Snowflake MCP Server — AI-Powered Data Platform Access with Cortex AI, SQL Orchestration, and Semantic Views

At a glance: GitHub — 286 stars, 92 forks, Python, [DEPRECATED]. PyPI — snowflake-labs-mcp v1.4.2. Official first-party from Snowflake. Apache 2.0 license. The open-source repo is now deprecated — Snowflake is directing all users to the managed cloud endpoint. Part of our Data & Analytics category.

Recent Updates (May 2026)

The open-source Snowflake-Labs/mcp repository is now officially deprecated. As of v1.4.2 (May 15, 2026), Snowflake has begun the deprecation process and is directing all users to migrate to the managed, cloud-hosted MCP server. The v1.4.2 release updated library dependencies for security (fastmcp, mcp, requests) and explicitly initiates the end-of-life path for the open-source server. Snowflake’s strategic direction is now the managed endpoint — zero infrastructure, built-in OAuth and RBAC, and access to the full Cortex AI suite.

Cortex Agents MCP connectors expand significantly: Snowflake’s managed MCP server now supports MCP connectors for Jira, Salesforce, Gmail, Google Calendar, Google Docs, and Slack — positioning Snowflake as an orchestration layer across enterprise data and workflow tools, not just a data warehouse.

New AI client integrations: The managed MCP server now lists 15+ supported AI platforms: Amazon Bedrock AgentCore, Azure AI Foundry, Augment Code, Claude, CrewAI, Cursor, Devin (Cognition), Glean, Kumo, Mistral AI, Salesforce Agentforce, UiPath, Windsurf, Workday, and WRITER. Enterprise data partnerships (MSCI, Nasdaq, Associated Press, eVestment) are now bundled in.

Appian partnership (April 28, 2026): At Appian World 2026, Appian announced integration with Snowflake via MCP, positioning Appian as “the AI orchestration layer for Snowflake’s AI Data Cloud.” Snowflake VP of AI Baris Gultekin confirmed the partnership.

Snowflake Summit 26 (June 1–4, 2026): The annual Summit at Moscone Center, San Francisco will feature Anthropic Co-President Daniela Amodei in the opening keynote alongside Snowflake CEO Sridhar Ramaswamy — a strong signal that Claude/MCP integration will be prominent. The Builder Keynote on June 3 focuses on deploying AI agents at scale on the Snowflake AI Data Cloud.

The Snowflake MCP Server is the official first-party MCP integration for working with the Snowflake Data Cloud. It provides AI assistants with access to Snowflake’s Cortex AI suite — search over unstructured data, natural language to SQL via semantic models, agentic orchestration across data sources — plus SQL execution with fine-grained permission controls, database object management, and semantic view querying.

Snowflake was founded in July 2012 by Benoit Dageville, Thierry Cruanes, and Marcin Żukowski. The company pioneered cloud-native data warehousing with separation of storage and compute. As of fiscal year 2026 (ended January 31, 2026): 9,060 employees and $4.68B annual revenue (29% YoY growth). Snowflake is publicly traded on NYSE (SNOW).

Snowflake offers two MCP deployment options: an open-source local server (Snowflake-Labs/mcp on GitHub) and a managed MCP endpoint built into the Snowflake platform (GA since November 2025). This review covers both, with emphasis on the open-source server.

What It Does

The server provides integrated tooling across six primary domains:

Cortex Search

Query unstructured data in Snowflake, commonly used in Retrieval Augmented Generation (RAG) applications. Search services are configured per database/schema with descriptive labels for the LLM to select the right source.

Cortex Analyst

Query structured data via semantic views — Snowflake’s approach to natural language SQL generation. The LLM describes what it wants, and Cortex Analyst generates the SQL based on the semantic model’s business logic and relationships.

Cortex Agent

Agentic orchestration across both structured and unstructured data sources. Cortex Agents combine Cortex Search and Cortex Analyst capabilities into a single tool that can reason across multiple data domains.

Object Management

SQL Execution (Query Manager)

Run LLM-generated SQL with user-configured permissions. The permission system uses allowlists and blocklists to control which SQL statement types are permitted:

sql_statement_permissions:
  - type: SELECT
    permission: ALLOW
  - type: CREATE
    permission: ALLOW
  - type: DROP
    permission: DENY
  - type: DELETE
    permission: DENY

This is a standout safety feature — you can let AI assistants query data while preventing destructive operations.

Semantic View Querying (Semantic Manager)

Discover and interact with Snowflake’s semantic views, which provide business-friendly abstractions over raw database tables.

Setup & Configuration

The open-source server is installed and run via uvx:

{
  "mcpServers": {
    "snowflake": {
      "command": "uvx",
      "args": [
        "snowflake-labs-mcp",
        "--service-config-file", "/path/to/config.yaml",
        "--account", "your-account",
        "--user", "your-user",
        "--password", "your-password"
      ]
    }
  }
}

Service Configuration

Services are declared in YAML with three categories:

agent_services:
  - name: "my_agent"
    description: "Orchestrates across sales and support data"
    database: "MY_DB"
    schema: "PUBLIC"

search_services:
  - name: "doc_search"
    description: "Search internal documentation"
    database: "DOCS_DB"
    schema: "PUBLIC"

analyst_services:
  - name: "revenue_analyst"
    description: "Revenue and financial metrics"
    semantic_model: "@MY_DB.PUBLIC.REVENUE_MODEL"

other_services:
  object_manager: true
  query_manager: true
  semantic_manager: true

Authentication Methods

The server leverages the Snowflake Python Connector and supports:

Connection parameters can be passed as CLI arguments or environment variables (SNOWFLAKE_ACCOUNT, SNOWFLAKE_USER, SNOWFLAKE_PASSWORD, SNOWFLAKE_PRIVATE_KEY, etc.).

Transport Options

Supported AI Clients

Open-source server: Claude Desktop, Cursor, VS Code with GitHub Copilot, Codex CLI, fast-agent. (Deprecated — users directed to managed endpoint.)

Managed MCP server: Amazon Bedrock AgentCore, Azure AI Foundry, Augment Code, Claude, CrewAI, Cursor, Devin (Cognition), Glean, Kumo, Mistral AI, Salesforce Agentforce, UiPath, Windsurf, Workday, WRITER.

Docker Deployment

Docker and Docker Compose configurations are provided for containerized deployments, with environment variable injection for credentials and volume mounting for config files.

Managed MCP Server (Cloud Endpoint)

Snowflake also offers a managed MCP endpoint built directly into the platform — no separate server to deploy. This went GA on November 4, 2025.

Managed Server Tools

Managed Server Setup

Created via SQL:

CREATE MCP SERVER my_mcp_server
  FROM SPECIFICATION $$
    tools:
      - name: "search_docs"
        type: "CORTEX_SEARCH_SERVICE_QUERY"
        identifier: "my_db.my_schema.doc_search"
        description: "Search internal documentation"
  $$;

Endpoint format: https://<account_URL>/api/v2/databases/{db}/schemas/{schema}/mcp-servers/{name}

Managed Server Authentication

OAuth 2.0 via Snowflake security integrations. Snowflake explicitly recommends OAuth over hardcoded tokens to prevent credential leakage.

Managed Server Limitations

• No resources, prompts, roots, or notifications support
• No streaming responses
• No version negotiation
• Semantic views only (not semantic models) for Cortex Analyst
• Not available in government regions

Development History

The managed server launched alongside Snowflake Cortex AI for Financial Services, signaling Snowflake’s investment in AI-native data access. The open-source server provides broader flexibility with local deployment and additional transport options.

Pricing Impact

The MCP servers themselves are free — both the open-source server (Apache 2.0) and the managed endpoint. However, all operations run against Snowflake, which uses consumption-based pricing:

Cortex AI features (Search, Analyst, Agents) consume additional credits based on usage. Prepaid capacity contracts offer 15-40% discounts over on-demand pricing.

Comparison with Alternatives

Snowflake-Labs MCP vs isaacwasserman’s server: The official server integrates deeply with Cortex AI (Search, Analyst, Agents) — capabilities the community server doesn’t offer. isaacwasserman’s server focuses on direct SQL execution and schema discovery, with a simpler setup and an insights memo feature that summarizes discovered data patterns. For pure SQL workflows, either works; for Cortex AI, only the official server applies.

Open-source vs Managed endpoint: The managed endpoint requires zero infrastructure — just a CREATE MCP SERVER SQL statement — and provides built-in OAuth, RBAC, and Snowflake-managed security. The open-source server offers more flexibility: local deployment, Docker containers, multiple transports, and the full object management toolkit. Organizations with strict compliance requirements may prefer the managed endpoint; developers wanting maximum control will prefer the open-source server.

Known Issues

1. Hostname underscore bug — Hostnames containing underscores cause connection failures. Use hyphens instead. This is a known gotcha that affects users with certain Snowflake account identifiers
2. Semantic views only (managed) — The managed MCP server’s Cortex Analyst tool only supports semantic views, not the older semantic models format. Organizations with existing semantic models must migrate to semantic views
3. No streaming responses (managed) — The managed endpoint does not support streaming, which can be noticeable for large result sets or complex queries
4. Permission granularity complexity — The managed endpoint requires separate permission grants for the MCP server itself and for each individual tool. This is good for security but can be tedious to configure for many tools
5. Government region exclusion — The managed MCP server is not available in Snowflake government regions, limiting options for public sector organizations
6. Tool poisoning risk — Snowflake warns that using multiple MCP servers without verification can lead to tool poisoning or tool shadowing vulnerabilities. They recommend verifying third-party servers before use
7. Deprecated CLI arguments — Several CLI arguments (--account-identifier, --pat) are deprecated in favor of new names (--account, --password). Documentation and examples may still reference the old names
8. Permission middleware bypass — Semantic view tools bypass the permission middleware due to an if/elif logic error (#166). Still open as of May 2026; PR #167 was opened in February but has not merged. Given the deprecation, resolution is uncertain
9. Authentication token expiry — The server fails until manually restarted when authentication credentials expire (#176). Confirmed still present in v1.4.2 as of May 16, 2026. PR #180 proposes auto-reconnection logic but remains unreviewed — and with deprecation now announced, it may not be merged
10. Open issues on GitHub — 19 open issues as of May 2026; the repo is now deprecated so these are unlikely to be resolved by Snowflake
11. Open-source repo deprecated — v1.4.2 (May 15, 2026) initiates formal deprecation. Users running the open-source server should plan migration to the managed endpoint. No future feature work is expected

The Bottom Line

Rating: 4 out of 5

The major development since the last review is the deprecation of the open-source Snowflake-Labs/mcp repository — v1.4.2 (May 15, 2026) initiated the end-of-life process, with Snowflake directing all users to migrate to the managed endpoint. This is not a setback; it’s a strategic consolidation. Snowflake’s managed MCP server now supports 15+ AI platforms (Amazon Bedrock AgentCore, Azure AI Foundry, Salesforce Agentforce, Windsurf, Workday, and more), MCP connectors for Jira, Salesforce, and Google Workspace, and enterprise data partnerships with MSCI, Nasdaq, and the Associated Press. Over 9,100 Snowflake accounts now use Cortex AI weekly, with 200%+ growth in AI workloads.

The Snowflake MCP Server earns its rating through official first-party backing from a major data platform ($4.68B revenue, 9,060 employees), deep Cortex AI integration that no community server offers (Search for RAG, Analyst for natural language SQL, Agents for multi-source orchestration), and a rapidly expanding ecosystem with enterprise partners, cloud platform integrations, and workflow tool connectors. The managed endpoint’s SQL command (CREATE MCP SERVER) remains the easiest entry point — built-in OAuth, RBAC, and zero infrastructure.

The open-source server’s deprecation resolves the dual-path confusion but also closes the door on local deployment flexibility, Docker containers, and the full object management toolkit. Known security issues (#166 permission middleware bypass, #176 auth token expiry) remain open and are now unlikely to be resolved. The managed endpoint’s limitations — no streaming, semantic views only, no government regions — apply to anyone moving off the open-source path. Snowflake Summit 26 (June 1–4) with Anthropic’s Daniela Amodei in the opening keynote is expected to bring further MCP announcements.

For data engineers and analysts working with Snowflake, the path forward is the managed endpoint. The Cortex Search integration enables RAG over unstructured data, Cortex Analyst turns natural language into SQL via semantic views, and the connector ecosystem makes Snowflake an orchestration hub across enterprise tools. If you use Fivetran to load data into Snowflake, the two MCP integrations remain complementary: Fivetran MCP handles pipeline control (connector management, sync triggers, destination configuration), while Snowflake MCP handles query and analysis on the data once it lands.
