MCP and Government: How AI Agents Connect to Legislative Data, Open Data Portals, Census Systems, Procurement Platforms, and Public Sector Operations

Government operates the world’s largest collection of disconnected information systems. A single federal agency might maintain dozens of databases — each with its own access controls, data formats, retention policies, and regulatory constraints — while state and local governments add thousands more. Citizens navigate this fragmentation daily when they search for benefits across agencies, track legislation across chambers, or try to understand how public money gets spent. Government employees face it too, spending significant time bridging systems that were never designed to talk to each other.

The numbers reflect both enormous opportunity and real momentum. AI use cases across 11 federal agencies GAO reviewed nearly doubled — from 571 in 2023 to 1,110 in 2024 — with generative AI use cases increasing about nine-fold, from 32 to 282. Roughly 90% of US government agencies are adopting or planning to adopt AI, and 43% of public-sector employees now use AI at least a few times per year — up from 17% in early 2023. Grand View Research’s market model puts the AI-in-government-and-public-services market at roughly $22–26 billion in 2024–2025, projected to $98–136 billion by the early-to-mid 2030s at close to an 18% CAGR — market-size forecasts like this vary meaningfully by methodology and vendor, so treat the range as directional rather than precise (the source blocked our automated re-verification during this audit; the URL is live and the figures match what we captured when this guide was first written).

MCP provides a structured protocol for connecting AI assistants to government data sources and systems. Rather than building custom integrations for each agency API, legislative database, open data portal, and procurement platform, MCP-connected agents can query congressional records, search open data catalogs, look up census statistics, track federal contracts, monitor regulatory changes, and access court records — all through defined tool interfaces with consistent authentication and error handling.

This guide covers the government and public sector MCP ecosystem — legislative tracking, open data portals, census and demographics, procurement and contracting, courts and legal systems, tax, emergency management, civic and municipal services, and architecture patterns for public sector AI operations. Our analysis draws on published documentation, open-source repositories, government announcements, and public sector reporting — we research and analyze rather than deploying these systems ourselves.

Why Government Needs MCP

Government has characteristics that make standardized AI integration both exceptionally valuable and uniquely constrained:

Data fragmentation is the defining challenge. Federal agencies alone maintain thousands of distinct databases and APIs — from Congress.gov and the Federal Register to SAM.gov, USASpending, EDGAR, and hundreds more. State governments add their own legislative tracking, court systems, licensing databases, and open data portals. Municipal governments layer on 311 systems, permitting, zoning, and local records. No single integration approach covers this landscape. MCP servers that wrap individual government APIs into standard tool interfaces make cross-agency AI queries practical without requiring each agency to redesign its systems.

Security and compliance requirements are non-negotiable. Government systems operate under strict frameworks — FedRAMP for cloud services, FISMA for information security, NIST 800-53 for security controls, CJIS for criminal justice data, ITAR for defense trade data. Any AI integration must respect these boundaries. MCP’s structured tool definitions enable fine-grained access controls, audit logging, and data classification enforcement that general-purpose API approaches don’t inherently provide.

Transparency and accountability are fundamental. Government data is public by default (with specific exceptions), and citizens have a right to understand how AI systems use their data and make recommendations. MCP’s explicit tool calls — where each action is visible and auditable — align well with government requirements for explainability and accountability that opaque AI integration approaches cannot satisfy.

Accessibility requirements apply universally. Section 508 requires federal digital services to be accessible to people with disabilities. Only 23% of top-visited federal websites fully conformed with accessibility standards in FY2024, and 37% conformed in the FY2025 assessment — though GSA itself cautions that reporting-methodology changes make a direct year-over-year comparison unreliable. AI agents that interact with government data through MCP must ensure their outputs support accessible formats and comply with WCAG 2.2 standards.

Scale and diversity of use cases are unmatched. Government AI applications span constituent services, policy analysis, regulatory enforcement, procurement optimization, fraud detection, emergency response, urban planning, and dozens of other domains. A standardized integration protocol means an AI agent built for legislative research can be extended to regulatory monitoring or procurement analysis without rebuilding the integration layer.

Comprehensive Government MCP Servers

The government MCP ecosystem spans legislative tracking, open data, census, procurement, courts, tax, emergency management, civic services, and international government data. Dedicated regulatory-compliance MCP tooling (mapping rules to NIST/CMMC-style frameworks, tracking Federal Register actions) is one of the thinner categories — see “Ecosystem Gaps” below.

Comprehensive Multi-Agency Platforms

US Government Open Data MCP (108 stars) is the most comprehensive US government MCP server we found, providing 300+ tools across 40+ federal APIs — Treasury, FRED, BLS, BEA, EIA, Congress.gov, Federal Register, GovInfo, Regulations.gov, FEC, Senate Lobbying, SEC, FDIC, CFPB, CDC, FDA, CMS, ClinicalTrials.gov, NIH, NHTSA, DOL, EPA, NOAA, NREL, USGS, FBI Crime Data, DOJ News, USPTO, Census, HUD, FEMA, BTS, USDA, and World Bank among them. It features WASM-sandboxed JavaScript execution that the README says cuts context-window usage 98-100% on large responses, selective module loading, dual transport (stdio and HTTP), disk-backed caching, and rate limiting.

Gov MCP Servers Collection (5 stars) takes a modular approach with 13 production servers providing roughly 50 tools total. Specialized servers cover safety recalls (NHTSA, FDA), natural disaster intelligence (FEMA, NOAA, USGS), federal financial intelligence (SEC EDGAR, CFPB, BLS), immigration and travel (visa bulletins, border wait times), environmental compliance (EPA, HUD), government contracts (SAM.gov, USASpending), court records (PACER, federal courts), public health (NIH, FDA adverse events), business entities (SEC, SBA), regulatory monitoring (Federal Register, Regulations.gov), grant finding (Grants.gov, USASpending), competitive intelligence (patents, trade), and cybersecurity vulnerabilities (NIST NVD, CISA KEV, MITRE ATT&CK).

Legislative and Congressional Data

Congressional data is one of the most active areas in government MCP development, with multiple servers providing different levels of depth.

CongressMCP (32 stars) offers the deepest coverage with 90+ operations across seven toolsets: Bills (16 operations), Laws (2), Amendments (7), Treaties and Summaries (5), Members and Committees (13), Voting and Nominations (13), and Records and Hearings (10+). It supports both stdio and HTTP transport with response caching and configurable TTL.

Congress.gov MCP by AshwinSundar (19 stars) provides 50+ endpoint paths covering bills, amendments, members, committees, and congressional records in Python. A TypeScript alternative from bsmi021 (8 stars) takes a resource-oriented approach with MCP Resources for Bills, Members, Congresses, and Committees alongside two primary search tools.

LegiScan MCP (10 stars) extends legislative tracking beyond Congress to all 50 US states, with 10 tools including composite operations that collapse multi-step research workflows into single tool calls, reducing agent-to-tool round trips for common queries.

Open Data Portals

Open government data represents one of the most developed MCP categories, with an official French government server leading in adoption.

data.gouv.fr MCP (1.6k+ stars) is the highest-starred government MCP server in our sample and an official deployment by the French government’s open data platform — its own README doesn’t claim to be the first official government MCP deployment, so we’re not repeating that claim. It provides roughly 10 tools across dataset search and retrieval, third-party data-service management, and metrics. A public hosted instance runs at mcp.data.gouv.fr/mcp — no local setup required.

CKAN MCP Server by ondata (57 stars) connects to CKAN portals worldwide — including data.gov and national portals across Europe, Asia, and Latin America — with tools across search, organizations, groups, and DataStore queries.

Data.gov MCP Server (19 stars) offers direct access to the US federal open data portal with 4 tools for package search, dataset details, group listing, and tag browsing.

OpenDataMCP (155 stars) takes a platform approach, providing a CLI tool (odmcp) for setting up MCP servers for any open data portal with a template-based provider system. It’s building toward covering roughly 12,000 Swiss open datasets as an initial target.

Census and Demographics

The US Census Bureau has published an official MCP server — a notable milestone for government adoption of the protocol.

US Census Bureau Data API MCP (88 stars) is an official Census Bureau project (published under the uscensusbureau GitHub organization) providing 4 tools: List Datasets, Fetch Dataset Geography, Fetch Aggregate Data, and Resolve Geography FIPS codes. It uses TypeScript with PostgreSQL and Docker.

Procurement and Federal Contracting

Capture MCP Server (30 stars) is the most complete procurement MCP server we found, with up to 15 tools across USASpending.gov (4 tools, no API key required), SAM.gov (4 tools), data-joining operations (2 tools), and Tango API integration (5 tools) — the server enables tools progressively as API keys are supplied.

Courts and Legal Systems

UK Case Law MCP (26 stars) provides semantic search and case retrieval across UK courts and tribunals (Supreme Court, Court of Appeal, High Court divisions, and several tribunals) from 2003 onward, querying The National Archives’ case law API.

Tax and Revenue

IRS Taxpayer MCP (8 stars) is notable for its privacy-first design: 39 tools covering federal tax calculations, deductions, credits, retirement planning, state taxes, IRS information, and the 2025 One Big Beautiful Bill Act — all executing 100% locally with zero network calls. It supports both TY2024 and TY2025.

Emergency Management and Weather

Weather MCP (36 stars) provides 17 tools for a one-call weather summary plus forecasts, alerts, air quality, marine conditions, radar, lightning, river monitoring, wildfire tracking, and historical data back to 1940. It uses the NOAA API for the US and Open-Meteo internationally with no API keys required.

The Gov MCP Servers Collection includes a natural disaster intelligence server with tools covering FEMA, NOAA, and USGS data.

Civic and Municipal Services

City Navigator (15 stars) emerged from a San Diego hackathon with a Civic MCP Server providing 10 tools and 5 resources. It supports five languages (English, Spanish, Filipino, Arabic, Korean), permit guidance, 311 issue reporting, and budget transparency.

Civicnet MCP Server (2 stars) implements a federated platform for neighborhood, city, or org-level nodes with GIS data ingestion, civic-principle enforcement (equity, truth, privacy, transparency), what-if/participatory simulation capabilities, and a full audit trail of agent steps and data sources.

International Government MCP Servers

Parliament MCP (27 stars) comes from the UK government’s Incubator for AI (i.AI), providing 13 tools for election results, member search, ministerial roles, departments, committees, parliamentary questions, and debates. It features vector database semantic search using Qdrant and AWS Lambda deployment for data ingestion.

Parliament MCP and the official French data.gouv.fr server (covered in the open data section above) show that government MCP adoption isn’t a US-only phenomenon, though our research turned up far fewer verifiable non-US, non-UK, non-French government MCP projects than the pace of US federal releases.

Government-Adjacent: Health, Education, and Finance Regulators

OpenFDA MCP Server (21 stars) provides 10 tools — 6 for drug data (adverse events, labels, NDC codes, recalls, approvals, shortages) and 4 for device data (510(k) clearances, classifications, adverse events, recalls) — against the openFDA API.

Education Data MCP (2 stars) connects to the Urban Institute Education Data API covering schools, school districts, and colleges.

Government MCP Server Comparison

Star and tool counts above are from live GitHub data pulled during this audit (August 2026) and will keep drifting — click through for current figures. A number of servers referenced in earlier drafts of this guide (a “US Compliance MCP,” “US Legal MCP,” “US Legal Tools,” “Federal Register MCP,” “CourtListener MCP,” “Open Legal Compliance MCP,” “Open Census MCP,” “Census API MCP,” “BankRegPulse,” “NOAA Tides and Currents MCP,” “Israeli Government Data MCP,” “Hong Kong Open Data MCP,” “Canada Open Government MCP,” “OpenDiscourse MCP,” and two secondary CKAN forks) have been removed from this page: their repos are either gone, or we could not confirm with confidence which of several similarly-named projects (if any) the original figures described. If you know a specific, actively-maintained project in one of those categories, let us know.

Architecture Patterns for Government MCP

Government MCP deployments must navigate unique constraints around security boundaries, data classification, compliance frameworks, and multi-level access controls. These patterns reflect common approaches to structuring government AI integrations.

Pattern 1: Federated Multi-Agency Query

This pattern enables AI agents to query across multiple government agencies while respecting each agency’s access controls and rate limits.

┌─────────────────────────────────────────────────┐
│                   AI Assistant                   │

└──────────┬──────────┬──────────┬────────────────┘
           │          │          │
     ┌─────▼──┐ ┌────▼───┐ ┌───▼────────┐

   │Congress│ │Fed Reg  │ │Regulations │
   │.gov API│ │  API    │ │.gov API    │
   └────────┘ └─────────┘ └────────────┘

The agent queries legislative history through CongressMCP, and the diagram’s other two legs illustrate the same pattern applied to the Federal Register and Regulations.gov APIs — correlating activity across the legislative and regulatory pipeline. We did not find a currently-maintained, verifiable dedicated MCP server for either the Federal Register or Regulations.gov at the time of this audit, so treat those two legs as an architecture pattern to build against those agencies’ own public APIs, not a specific product recommendation.

Pattern 2: Open Data Intelligence Hub

This pattern uses CKAN and open data MCP servers to aggregate insights across national and international data portals.

┌─────────────────────────────────────────────────┐
│                   AI Assistant                   │

└────┬──────────┬──────────┬───────────────────────┘
     │          │          │

│Portals │ │Open    │ │Census│
│(global)│ │Data    │ │API   │
└────────┘ └────────┘ └──────┘

An analyst agent searches across CKAN portals worldwide via the ondata CKAN MCP server, the French government’s official data.gouv.fr MCP endpoint, and the official US Census Bureau MCP. This enables cross-country comparisons, dataset discovery, and demographic analysis without requiring the agent to know each portal’s specific API.

Pattern 3: Procurement and Spending Analysis

This pattern connects procurement, spending, and regulatory data to support contract research and government accountability.

┌─────────────────────────────────────────────────┐
│                   AI Assistant                   │
│        (Procurement Research Agent)              │
└──────┬──────────────────────┬────────────────────┘
       │                      │
 ┌─────▼────┐           ┌─────▼─────┐

 └────┬─────┘           └─────┬─────┘
      │                       │
┌─────▼──┐              ┌─────▼───┐
│SAM.gov │              │Treasury │

│Spending│              │BLS APIs │
└────────┘              └─────────┘

A procurement analyst agent uses Capture MCP to search SAM.gov registrations and USASpending awards, and cross-references with broader government financial data through the comprehensive US Gov Open Data MCP. This enables questions like “show me all contracts over $1M to companies registered in Virginia for cybersecurity services.” Matching those results against a specific compliance framework (NIST 800-53, CMMC, etc.) is a separate step today — we did not find a currently-maintained MCP server that does compliance-framework mapping, so that piece still needs a human reviewer or a non-MCP tool.

Pattern 4: Civic Services Gateway

This pattern supports municipal services where citizens interact with local government through AI-assisted interfaces.

┌─────────────────────────────────────────────────┐
│              Citizen-Facing Interface             │
│         (Multilingual, Section 508)              │
└──────────┬──────────┬──────────┬────────────────┘
           │          │          │
     ┌─────▼────┐ ┌───▼────┐ ┌──▼───────┐
     │ City     │ │Weather │ │Open Data │
     │Navigator │ │  MCP   │ │   MCP    │
     │  MCP     │ │(NOAA)  │ │          │
     └────┬─────┘ └───┬────┘ └────┬─────┘
          │           │           │
    ┌─────▼────┐ ┌────▼───┐ ┌────▼─────┐

    │Systems   │ │Weather │ │Data      │
    │Budget DB │ │Alerts  │ │Portal    │
    └──────────┘ └────────┘ └──────────┘

A citizen-facing AI assistant handles permit questions, 311 issue reporting, budget inquiries, weather alerts, and open data queries through separate MCP servers. The multilingual City Navigator MCP handles civic interactions while Weather MCP provides emergency alerting capability. This pattern requires strict attention to Section 508 accessibility and language support.

Security, Compliance, and Data Classification

Government MCP deployments face the most demanding security and compliance requirements of any sector. Understanding these frameworks is essential for any team building or deploying government AI integrations.

FedRAMP and Cloud Authorization

FedRAMP (Federal Risk and Authorization Management Program) is the mandatory standard for cloud services used by federal agencies. GSA’s FedRAMP 20x initiative has begun prioritizing authorization of AI-based cloud services, with a target of meeting 20x pilot authorization requirements within two months of a vendor qualifying. (An earlier draft of this guide cited specific January 2026 and mid-2026 authorization-timeline predictions and named vendors as already-authorized; GSA’s announcement doesn’t state those specifics, so they’ve been removed rather than left uncited.)

For MCP deployments, FedRAMP considerations include where MCP servers run (on-premise vs. authorized cloud), how data flows between MCP clients and servers, whether AI model inference happens within FedRAMP boundaries, and how audit logs are retained and protected.

NIST Security Frameworks

NIST 800-53 Rev 5 organizes its catalog of security and privacy controls into 20 control families (Access Control, Audit and Accountability, Configuration Management, Incident Response, and so on). It is the foundational control catalog for federal information systems.

NIST AI Risk Management Framework (AI RMF 1.0) provides voluntary guidance for AI system governance. The companion NIST AI 600-1 (July 2024) — the Generative AI Profile — walks through 12 categories of generative-AI risk (sections 2.1 through 2.12) with suggested mitigating actions. NIST’s separate AI 100-2e2025 report (March 2025) covers adversarial machine learning attack categories including poisoning, evasion, and privacy attacks. Sector regulators are increasingly referencing NIST AI RMF in their guidance.

FISMA and Continuous Monitoring

FISMA (Federal Information Security Modernization Act) legally requires federal agencies and their contractors to secure information systems. NIST 800-53 provides the specific controls, and agencies must maintain continuous monitoring programs. MCP servers used in federal environments must fit within an agency’s FISMA authorization boundary.

DoD Impact Levels

Department of Defense systems use Impact Levels (IL) to classify data sensitivity:

• IL2: Public and non-critical data — FedRAMP Moderate equivalent, commercial data centers within the US
• IL4: Controlled Unclassified Information (CUI) — FedRAMP Moderate plus DoD enhancements, citizenship verification required
• IL5: Higher-sensitivity CUI and mission-critical data — dedicated infrastructure, US citizens only
• IL6: Classified SECRET — SIPRNet connection, dedicated DoD/federal facilities, active SECRET clearances

These levels are defined in the DoD Cloud Computing Security Requirements Guide (SRG); Microsoft’s Azure Government IL5 guidance is a useful plain-language walkthrough of what IL5 isolation requires in practice. MCP servers handling DoD data must operate at the appropriate IL, which determines everything from where they can be hosted to who can access them.

CJIS Security Policy

CJIS (Criminal Justice Information Services) governs law enforcement data access. The FBI’s CJIS Security Policy Resource Center is the authoritative source for the current policy version and compliance deadlines — that page blocked our automated fetch during this audit (a common pattern for law-enforcement-portal .gov sites), so we could not independently re-confirm the specific Version 6.0 / December 2024 / October 2027 figures from earlier drafts of this guide against the live document. Readers relying on CJIS deadlines for compliance planning should check the resource center directly rather than this page. MCP servers that access criminal justice data — including court records via PACER — must comply with CJIS requirements.

Section 508 and Accessibility

Section 508 requires federal digital services to be accessible. Only 23% of top-visited federal websites fully conformed with accessibility standards in FY2024, improving to 37% in the FY2025 assessment (GSA cautions that reporting-methodology changes make a direct comparison unreliable). WCAG 2.2 is now incorporated into 508 standards. UsableNet’s 2025 midyear tracker put website accessibility lawsuits on pace for roughly 4,975 filings in 2025, a “nearly 20%” increase over 2024’s 4,187. Separately, under DOJ’s Title II web/app accessibility rule, state and local government entities serving populations of 50,000+ must comply by April 26, 2027, with smaller entities and special districts given until April 26, 2028.

AI agents that serve government functions must ensure their interfaces and outputs comply with accessibility requirements — this includes screen reader compatibility, keyboard navigation, sufficient color contrast, and clear language.

Data Classification and Handling

Government data exists on a spectrum from fully public (open data portals, published regulations) to highly classified (national security, intelligence). MCP servers must enforce appropriate handling for each classification level:

• Public data (data.gov, Census, Federal Register): Can flow freely through MCP, suitable for stdio transport
• Controlled Unclassified Information (CUI): Requires encryption in transit, access controls, audit logging
• Personally Identifiable Information (PII): Subject to the Privacy Act, requires minimization and purpose limitation
• Law enforcement data: CJIS controls apply, background checks may be required
• Classified data: Cannot traverse standard MCP channels, requires isolated infrastructure

Executive Orders and Policy Framework

Executive Order 14365, “Ensuring a National Policy Framework for AI” (issued December 11, 2025) directs the Attorney General to stand up a DOJ AI Litigation Task Force to challenge state AI laws, and calls for a uniform federal policy framework that preempts conflicting state AI laws — with carve-outs for child-safety protections and state government procurement/use of AI. OMB Memorandum M-25-21 (“Accelerating Federal Use of AI through Innovation, Governance, and Public Trust,” issued April 3, 2025) requires each agency to stand up an AI Governance Board within 90 days of issuance (July 2, 2025) and sets a 270-day deadline (December 29, 2025) for agencies to update related policies. OMB M-25-22 addresses AI procurement.

These policies create both opportunity (agencies are mandated to explore AI) and constraint (governance boards must approve AI deployments, including MCP-based integrations).

Ecosystem Gaps and Opportunities

The government MCP ecosystem is growing rapidly but has significant gaps that represent opportunities for developers and vendors.

No FOIA/public records MCP server exists. Despite Freedom of Information Act requests being one of the most common citizen-government interactions, no MCP server automates FOIA filing, tracking, or response processing. Building one that connects to agencies’ FOIA portals would serve journalists, researchers, and transparency advocates.

Regulatory-compliance mapping is a gap, not a category. Earlier drafts of this guide named several dedicated regulatory/compliance and legal-research MCP servers (mapping NIST/CMMC-style frameworks, tracking Federal Register actions, aggregating CourtListener/eCFR data). On re-audit, we couldn’t confirm several of those repos still exist, and couldn’t confidently match others to a single verifiable project among multiple similarly-named ones. Net effect: dedicated compliance-mapping and Federal Register MCP tooling looks thinner right now than the legislative and open-data categories.

Election and voting data is underserved. We found no MCP server providing access to US election data (FEC filings, state election results, redistricting, voter registration statistics). This is a sensitive but important area for democratic transparency.

State and local government coverage is thin. The overwhelming majority of government MCP servers focus on federal data. State legislatures, state courts, county records, municipal code, and local open data portals have minimal MCP coverage despite being the government layer citizens interact with most frequently. This gap is especially significant given the explosion of state-level AI legislation — 1,561 bills across 45 states in 2026 alone — which is creating a patchwork of compliance requirements that MCP tooling does not yet address.

No benefits eligibility or navigation tools. Government benefits (SNAP, Medicaid, housing assistance, veteran benefits) require citizens to navigate complex eligibility rules across multiple agencies. An MCP server that could query eligibility criteria and application status across programs would have significant public impact.

Grants discovery needs improvement. While the Gov MCP Servers Collection includes a grant finder, a dedicated Grants.gov MCP server with deep search, eligibility matching, and deadline tracking would serve researchers, nonprofits, and small businesses.

International coverage beyond open data is limited. The UK Parliament MCP and various open data servers exist, but legislative tracking, procurement, and regulatory compliance for non-US governments have minimal MCP coverage.

Air-gapped and classified environment tooling is absent. MCP servers designed for disconnected or classified networks — common in defense and intelligence — don’t exist in the open-source ecosystem. This is likely being developed behind classification boundaries.

Getting Started by Role

Policy researchers and analysts: Start with CongressMCP (90+ operations for legislative data) and the US Gov Open Data MCP for cross-agency economic and demographic data. We did not find a currently-maintained dedicated Federal Register MCP server, so regulatory tracking today means working against the Federal Register API directly or through the US Gov Open Data MCP’s broader coverage.

Open data practitioners: Begin with the CKAN MCP server (ondata) for access to CKAN portals worldwide, or the official French data.gouv.fr MCP if working with European data. Add the Census Bureau MCP for demographics and OpenDataMCP for building custom portal connections.

Government contractors and procurement teams: The Capture MCP server provides the most complete procurement workflow with SAM.gov and USASpending integration. We could not identify a currently-maintained MCP server dedicated to compliance-framework mapping (NIST 800-53, CMMC, etc.) — that step still needs a human reviewer or a non-MCP tool today.

Civic technologists: City Navigator provides a template for municipal AI services. Civicnet MCP offers a federated approach for multi-city deployments. Weather MCP adds emergency alerting capability.

Legal researchers: UK Case Law MCP is the strongest verified option for cross-jurisdiction UK case research. For US legal/regulatory research (Congress.gov, Federal Register, CourtListener), several small community MCP servers exist, but we couldn’t confirm which of several similarly-named projects (if any) matches the specific tool counts cited in earlier drafts of this guide — check GitHub directly before adopting one.

Tax and financial analysts: IRS Taxpayer MCP provides privacy-first local tax calculations. For broader financial data, the US Gov Open Data MCP covers Treasury, FRED, BLS, SEC, FDIC, and CFPB.
