MCP at the Edge: Deploying AI Agent Tools Closer to Users, Devices, and Data

MCP servers don’t have to live in a central data center. Edge computing — running code at network locations close to users and devices — is a natural fit for MCP tool calls. When a user in São Paulo calls an MCP tool, why route it through us-east-1 when a Cloudflare Worker in São Paulo can handle it in under 10ms?

The edge MCP ecosystem is maturing fast. Cloudflare’s Agents SDK includes a dedicated McpAgent class running across 300+ data centers. Fastly built a security-focused MCP server on their WebAssembly-based Compute platform. The wasmcp project lets you write MCP servers as portable WASM components deployable to any WASI-compatible runtime. IoT researchers have demonstrated MCP servers running on ESP32 microcontrollers with 205ms response times across 22 sensor types. And MCP over MQTT extends the protocol to bandwidth-constrained IoT networks.

This guide covers where edge MCP works, the patterns that make it effective, and when you should stick with centralized deployment. Our analysis draws on published documentation, GitHub repositories, research papers, and vendor materials — we research and analyze rather than deploying these systems ourselves.

Why Edge MCP Matters

Traditional MCP deployments put servers in a single cloud region. Every tool call travels from client to that region and back. For many use cases, this is fine — 50-100ms round trips are acceptable for database queries or API integrations.

But several scenarios demand lower latency or local execution:

Global user distribution. If your MCP clients are worldwide, edge deployment cuts latency from 50-100ms to 1-10ms by running tool logic at the nearest edge location.

IoT and device interaction. Controlling a smart thermostat or reading a factory sensor shouldn’t route through a distant cloud region. Local MCP servers respond faster and work without internet connectivity.

Data sovereignty. Some data can’t leave a geographic region. Edge MCP servers keep data processing local, satisfying residency requirements without complex proxy architectures.

Real-time applications. Voice assistants, robotics, and industrial control systems need sub-10ms tool responses. Edge deployment is the only way to hit these targets consistently.

Bandwidth efficiency. Sending raw telemetry to the cloud for processing wastes bandwidth. Edge MCP servers can filter, compress, and summarize data before forwarding — what AWS calls “semantic compression.”

Edge Platforms for MCP

Cloudflare Workers: The Most Mature Edge MCP Platform

Cloudflare has the deepest edge MCP integration. Their Agents SDK provides a McpAgent class that extends the base Agent class, backed by Durable Objects for stateful sessions with WebSocket Hibernation (the Worker sleeps during inactivity, preserving state without billing).

Transport options:

• Streamable HTTP — Production standard for remote MCP access
• SSE — Legacy support for older clients
• RPC bindings — Internal Worker-to-Worker communication via Durable Objects, no public internet traversal

Key projects:

• cloudflare/workers-mcp (644+ stars, used by 880+ repositories) — Connects Claude Desktop directly to Cloudflare Workers
• mcp-server-cloudflare (4,000+ stars) — 16 official Cloudflare service MCP servers
• mcp-server-worker — Semantic search with Workers AI + Vectorize; the project’s own cost estimate for 100,000 monthly searches is ~$5.40/month

Performance: V8 isolate architecture means near-zero cold starts. A documented distributed MCP architecture using 8 specialized Workers with service bindings reports sub-100ms global response times and auto-deployment across 300+ data centers.

Why Workers lead: CPU-time pricing (you pay for compute, not wall-clock time waiting on I/O), zero cold starts via V8 isolates, and Durable Objects for stateful session management without external databases.

For serverless-specific deployment details, see our MCP on Serverless guide.

Fastly Compute: WASM-Based Security-First Edge MCP

Fastly took a different approach — their Compute platform runs WebAssembly, providing browser-grade sandboxing for MCP tool execution. Each request runs in an isolated WASM instance with per-request isolation and near-instant startup.

The official Fastly MCP Server (released August 2025) has Tier 1 support. Their blog post “Building an actually secure MCP Server with Fastly Compute” details the security advantages of WASM sandboxing — tools execute in constrained environments with no filesystem or network access beyond what’s explicitly granted.

Fastly supports both Streamable HTTP and SSE for backward compatibility.

Vercel Edge Functions

Vercel’s Edge Runtime, built on V8 isolates, is architected for sub-5ms cold starts versus the hundreds of milliseconds typical of container-based serverless functions. The mcp-handler package (640+ stars) drops MCP into Next.js, Nuxt, SvelteKit, and Hono projects. Community boilerplate like sdiehl/mcp-on-vercel demonstrates stateless Python MCP on Vercel Functions.

Netlify Edge Functions

Built on the Deno runtime at Netlify’s CDN edge. Netlify’s guide documents deploying MCP servers with Streamable HTTP transport. The official netlify-mcp server covers project creation and deployment, access controls, extensions, environment variables/secrets, and form submission management. (A separate, third-party DynamicEndpoints/Netlify-MCP-Server claims a larger 43-tool surface including Blobs and Analytics — that is a different, community-maintained project, not Netlify’s own.)

Supabase Edge Functions

Deno-based serverless functions on Fly.io with sub-50ms latency. Uses mcp-lite, a zero-dependency TypeScript framework that works anywhere the Fetch API is available. Lightweight and practical for database-adjacent MCP servers.

Akamai EdgeWorkers

The ALECS MCP server breaks its tools out by domain — per the project’s README: Property Manager (31 tools), Edge DNS (24), Certificate/CPS (22), Security/WAF (95), and Reporting (19), around 190 tools in total. It manages CDN configurations, cache purging, EdgeWorkers deployment, and DNS records through natural language — a practical example of using MCP to manage edge infrastructure itself. Note the project describes itself as deliberately trimming scope (“stability over sprawl”) to a smaller set of verified, production-ready tools, so the exact count is a moving target.

AWS Lambda@Edge and CloudFront Functions

Lambda@Edge runs across CloudFront’s global network, which AWS currently lists at 750+ points of presence in 100+ cities across 50+ countries (AWS does not publish a Lambda@Edge-specific subset count). CloudFront Functions are lighter — AWS pricing puts CloudFront Functions at $0.10 per million invocations versus $0.60 per million requests for Lambda@Edge, a 1/6th ratio on the request-pricing axis (Lambda@Edge also bills separately for execution duration). AWS has the broadest serverless MCP ecosystem overall through awslabs/mcp and aws-samples/sample-serverless-mcp-servers.

Platform Comparison for Edge MCP

MCP on IoT and Embedded Devices

Edge computing’s other frontier is the device itself. MCP servers running on microcontrollers and single-board computers bring AI tool access directly to sensors, actuators, and local hardware.

ESP32: MCP on a $5 Microcontroller

Multiple projects demonstrate MCP running on ESP32 hardware:

• navado/ESP32MCPServer — WebSocket-based MCP server for resource discovery and monitoring
• ESP RainMaker MCP Server — Official Espressif integration for natural language IoT control
• emqx/esp-mcp-over-mqtt — MCP over MQTT protocol transport for ESP32. EMQX’s companion “Building Your AI Companion with ESP32 & MCP over MQTT” blog series (six-plus parts, hosted in the separate emqx/esp32-mcp-mqtt-tutorial repo) walks through building a voice-interactive AI companion, culminating in Part 4: Enabling Voice Interaction
• xiaozhi-esp32 (28,800+ stars) — Voice AI on ESP32 supporting 70+ hardware platforms

Raspberry Pi: Full MCP Server on ARM

ARM’s learning path demonstrates deploying MCP servers on Raspberry Pi 5 using FastMCP (Python). The server exposes tools like read_temperature, toggle_relay, and get_motion_status over JSON-RPC 2.0 — turning a Pi into an MCP-accessible sensor hub.

IoT-MCP Research: Production-Validated Architecture

A research paper (arxiv.org/html/2510.01260) presents a three-domain IoT-MCP architecture:

1. Local Host — LLMs + MCP servers
2. Datapool/Connection Server — Message routing and device registry
3. IoT Devices — Sensors and actuators

Results from testing with 22 sensor types across 6 microcontroller families: 100% task success rate, 205ms average response time, 74KB peak memory usage. A 12-hour production deployment in a multi-story building used 6 ESP32-S3 units.

An IEEE paper on IoT Robotics (IoRT), “Enabling Modular and Intelligent IoRT Systems: Integrating the Model Context Protocol for Semantic Decoupling at the Edge” (published January 2026), describes MCP enabling modular service composition and semantic decoupling — treating devices as callable resources and tools rather than requiring protocol-specific integration code.

Home Assistant: The Local-First Smart Home MCP

Home Assistant’s MCP Server integration (available since version 2025.2, used by 3.5% of active installations per Home Assistant’s own integration page) runs entirely locally — data stays on your network. The unofficial ha-mcp (4,300+ stars) provides 88 tools for comprehensive smart home control.

This is local-first edge computing in practice: no cloud dependency, low latency, full data privacy.

For more IoT MCP servers, see our Best IoT MCP Servers guide.

MCP over MQTT: Edge-Native Protocol Transport

EMQX’s MCP over MQTT implementation extends MCP to IoT and edge networks using MQTT’s lightweight transport. MQTT adds capabilities MCP’s HTTP transport lacks for IoT scenarios:

• QoS levels — At-most-once, at-least-once, and exactly-once delivery
• Message persistence — Broker stores messages for disconnected devices
• Built-in service discovery — Topic-based routing without a registry
• Bandwidth efficiency — Minimal overhead for constrained networks

This makes MCP viable on networks where HTTP’s overhead is prohibitive — factory floors, agricultural monitoring, remote installations.

WebAssembly: Portable, Secure MCP at the Edge

WebAssembly is emerging as the ideal runtime for edge MCP. WASM modules are portable (run anywhere), sandboxed (secure by default), and fast to start (no cold boot).

wasmcp: The WASM Component Development Kit for MCP

wasmcp (74+ stars, Apache 2.0, v0.4.13 as of March 2026) is the most complete WASM MCP framework. Key features:

• Polyglot — Write MCP tools in Rust, Python, or TypeScript, compile to a single WASM binary
• Middleware chain — Chain-of-responsibility pattern, described as “Unix pipes for MCP”
• Deploys everywhere — wasmtime, wasmCloud, Spin, any WASI-compatible runtime
• Edge scaling — Scales via Fermyon Wasm Functions across Akamai’s edge network

Wassette: Microsoft’s Security-Oriented WASM MCP Runtime

microsoft/wassette is a Rust-based runtime built on Wasmtime with a deny-by-default permission system. It fetches WASM Components from OCI registries and exposes them as MCP tools with zero runtime dependencies. Compatible with Claude Code, Cursor, VS Code Copilot, and Gemini CLI.

The security model is significant: each MCP tool runs in a WASM sandbox with explicit capability grants. A tool that queries a database cannot access the filesystem unless explicitly permitted. This is a stronger isolation model than process-based or container-based MCP servers.

Browser-Based MCP via WASM

beekmarks/mcp-wasm demonstrates MCP servers running directly in the browser via WebAssembly. A custom browser-transport.ts layer bridges the MCP protocol to the browser environment. This proves that browsers themselves can be MCP server runtimes — enabling client-side tool execution without any server infrastructure.

MCP.run: App Store for WASM MCP Servers

MCP.run operates as a registry and runtime for MCP servers packaged as WASM “servlets.” All servlets are WebAssembly modules — portable across OS, processor, browser, and device. The mcpx CLI manages installation and execution. Planned expansion includes serverless execution of WASM MCP servers.

Spin Framework: Composable WASM MCP

Fermyon’s Spin framework supports building MCP servers as composable WASM components. Deploys to Fermyon Wasm Functions, SpinKube (Kubernetes), or any WASI-compatible runtime — giving you a single build target with multiple deployment options.

WildFly: WASM MCP in Java

WildFly’s integration exposes WASI binaries as MCP tools via CDI and the Chicory JVM WASM runtime. Alpha stage, but demonstrates that Java application servers can host WASM-based MCP tools — useful for enterprises with existing Java infrastructure.

Edge AI: Small Models + MCP

One of the most promising edge MCP patterns pairs small language models (SLMs) running on-device with MCP for tool access. The SLM handles local reasoning; MCP connects it to tools, data, and (when needed) larger cloud models.

The SLM-LLM Bridge Pattern

Documented in detail by Data Reply, this pattern works in two tiers:

1. Edge tier — A small model (7B parameters) runs on local hardware, handling intent extraction, context summarization, and simple tool calls via MCP
2. Cloud tier — Complex reasoning tasks are forwarded to a large model (70-175B parameters) via MCP, with the SLM’s extracted context reducing token costs

The economics are compelling: serving a 7B model is 10-30x cheaper than a 70-175B model. NVIDIA’s research paper “Small Language Models are the Future of Agentic AI” provides the academic backing.

Semantic MCP Server: Edge AI for Telco

AWS’s Semantic MCP Server architecture demonstrates edge AI for telecommunications:

• Fine-tuned SLMs on AWS Outposts perform “semantic compression” — converting gigabytes of raw telemetry into kilobytes of diagnostic signals
• Only the compressed, meaningful data travels via MCP to cloud systems
• Reference model: Qwen 3 14B
• Results reported in the post: a 90% reduction in token consumption for root-cause analysis (by filtering noisy logs down to kilobytes of semantic data), 97.5% precision and 91.7% recall in root-cause identification (correctly identifying the cause in 773 of 1,000 test cases), a 93% reduction in false positives versus earlier iterations, and ~6.45 seconds average inference latency on a single NVIDIA A10 GPU

This pattern applies beyond telco — any scenario with high-volume sensor data benefits from edge-side semantic filtering before MCP transport.

On-Device Hardware

• Raspberry Pi 5 — Runs quantized models with MCP coordinating between inference engines and sensor pipelines
• NVIDIA Jetson — GPU-accelerated edge inference with MCP tool orchestration
• Qualcomm Snapdragon — NPU delivers up to 45 TOPS for on-device inference, with Qualcomm publishing guidance on MCP integration across cloud, edge, and real-world devices
• ARM Cortex-A — MCP server as runtime abstraction layer over device I/O

Edge Databases with MCP

Edge MCP servers often need data access. Several databases now offer both edge deployment and MCP integration:

Turso/libSQL: Distributed SQLite at the Edge

Turso provides edge-hosted distributed SQLite with built-in MCP server support via the CLI. Community servers include nbbaier/mcp-turso and spences10/mcp-turso-cloud (with two-level org/database auth).

The killer feature for edge MCP: embedded replicas. Local SQLite files auto-sync from the remote primary, giving edge MCP servers local-speed reads with eventual consistency from the central database.

Cloudflare D1: Serverless SQLite on the Edge

D1 is managed serverless SQLite deployed across Cloudflare’s edge network. Workers access D1 through bindings — no network hop, just a function call. MCP access comes through the Cloudflare Workers MCP server for D1 database management.

PlanetScale

Official MCP support via pscale mcp install / pscale mcp server. Provides read-only database access for AI tools — useful for MCP servers that need to query production data safely.

Neon Postgres

neondatabase/mcp-server-neon offers serverless Postgres with MCP for natural language database management. Safe migration workflows via temporary branches let MCP tools modify schemas without risking production.

DynamoDB

Official AWS MCP server at awslabs.github.io/mcp/servers/dynamodb-mcp-server with 8 tools for data modeling, validation, cost analysis, and code generation. Global Tables provide multi-region replication for edge access patterns.

For a broader database MCP survey, see our Best Database MCP Servers guide.

CDN-Level Caching and Routing for MCP

When MCP servers run at the edge, API gateways and CDN-level caching become important architectural components.

Gravitee MCP API Gateway

Gravitee’s MCP gateway provides protocol translation, caching, routing, and security. The caching strategy is nuanced:

• Cache: resources/list, prompts/list, resource content (read-heavy, rarely changing)
• Don’t cache: tools/call (has side effects), authentication flows
• Different TTLs: Resource listings can cache for minutes; tool schemas for longer

Envoy AI Gateway

The Envoy AI Gateway runs a lightweight MCP Proxy (Go) within an Envoy sidecar. This leverages Envoy’s existing load balancing, rate limiting, circuit breaking, and observability for MCP traffic — no new infrastructure required if you’re already running Envoy.

IBM ContextForge

IBM/mcp-context-forge is an open-source AI Gateway, registry, and proxy that federates MCP, A2A, REST, and gRPC APIs. Per its README, it offers 40+ plugins and Redis-backed federation and caching for multi-cluster Kubernetes deployments. Supports HTTP, JSON-RPC, WebSocket, SSE, stdio, and Streamable HTTP transports.

AWS Edge Architecture

A typical AWS edge MCP architecture combines Route 53 (DNS-based global routing), CloudFront (CDN caching for read-heavy MCP operations), and API Gateway (request management, auth, throttling) in front of Lambda@Edge MCP servers.

For more on MCP API gateways, see our Best API Gateway MCP Servers guide.

Latency Optimization Patterns

Running MCP at the edge is only half the battle — you need to optimize the server itself.

Cold Start Mitigation

Initial warm-up costs for MCP servers (loading models, database connections, configuration) can run into the seconds, while a warm, cached call can complete in under a millisecond — a difference of multiple orders of magnitude. Strategies:

• Schedule warm-up windows before peak traffic
• Keep-alive connections to databases and external APIs
• Lazy-load tools — initialize only the tools actually called, not all registered tools
• Use V8 isolates (Cloudflare, Vercel) or WASM (Fastly) for near-zero cold starts

Connection Pooling

Described as “80% of the performance win” in the MCP Mastery series. Size your connection pool to realistic peak load, not theoretical maximum.

Batching and Parallelism

Group independent tool calls to reduce round trips. Fire independent calls simultaneously rather than sequentially. This is a client-side optimization but dramatically improves perceived latency for multi-tool workflows.

Language Selection

MCP server performance benchmarks from tmdevlab.com show Java and Go MCP servers at 0.835ms and 0.855ms average latency respectively, both handling 1,600+ requests/second with sub-millisecond p50/p90.

Security at the Edge

Distributed MCP deployment introduces security challenges that centralized architectures don’t face.

Authentication Across Regions

MCP’s OAuth 2.1 foundation supports distributed auth through:

• Signed JWTs with scoped claims — edge servers validate tokens locally without calling an auth server
• OIDC provider delegation with OAuth Token Exchange — edge servers exchange tokens with a central identity provider
• mTLS for service-to-service communication between edge MCP servers
• Machine-to-machine OAuth client credentials for internal edge-to-cloud communication

Session Management

Updated for the current spec. The 2026-07-28 MCP specification revision removed protocol-level sessions and the Mcp-Session-Id header entirely (SEP-2567): servers that need cross-call state now mint their own explicit handles and pass them as ordinary tool arguments, rather than relying on a session ID header. For edge deployments, this removes a class of session-affinity problems outright — there is no protocol-level session to keep sticky across edge locations. Auth codes, tokens, and consent records still need to live in a shared external store (Redis, Firestore, Postgres) if /authorize and /token run on different edge instances, since OAuth flows are unaffected by the session-handling change.

Azure’s approach — API Management with Entra ID — provides multi-layered security with OAuth, credential management for backend API tokens, and a self-hosted gateway option for edge deployment.

WASM Sandboxing

Fastly Compute and Microsoft’s Wassette provide the strongest isolation model for edge MCP: each tool execution runs in a WASM sandbox with deny-by-default permissions. This is stronger than container-based isolation because the sandbox boundary is at the instruction level, not the process level.

For more on MCP security patterns, see our MCP Security Best Practices guide and MCP Compliance guide.

Offline-First MCP Patterns

No MCP-specific offline-first framework exists yet, but the patterns are well-established from Progressive Web App architecture:

• Service workers as network proxy — Cache-first or network-first strategies for MCP tool responses
• IndexedDB for structured local storage — Cache tool results and resource data locally
• Background Sync API — Queue MCP tool calls when offline, execute when connectivity returns
• Conflict resolution — Last-write-wins or user prompts when offline changes conflict with server state

MCP’s stateless-by-default Streamable HTTP transport (see above) is naturally compatible with store-and-forward patterns — each tool call is an independent HTTP request, so queuing and replaying is straightforward.

Local MCP servers using stdio transport run entirely offline on the device. The MCP specification’s local server documentation covers this pattern. Combined with on-device SLMs, this enables fully offline AI tool access.

Architecture Patterns

Pattern 1: Edge-Only (Stateless)

Client → Edge MCP Server (nearest location) → Response

Each request is independent. No session state. The edge server handles the tool call completely — reading from an edge database, calling a local API, or processing local data.

Best for: Read-heavy queries, IoT sensor readings, cached data lookups, location-based services.

Pattern 2: Edge + Cloud Hybrid

Client → Edge MCP Server → [Simple tools handled locally]
                          → [Complex tools forwarded to cloud MCP]

The edge server acts as a router. Simple, latency-sensitive tools execute locally. Complex tools requiring large models, cross-region data, or heavy compute are forwarded to centralized MCP servers.

Best for: Applications mixing real-time and batch operations, SLM-LLM bridge pattern, semantic compression.

Pattern 3: Edge Gateway + Federated Backends

Client → Edge Gateway (Envoy/ContextForge/Gravitee)
           → MCP Server A (edge)
           → MCP Server B (cloud)
           → REST API C (legacy)

An API gateway at the edge routes MCP requests to the appropriate backend — some at the edge, some in the cloud, some to legacy REST APIs with protocol translation.

Best for: Enterprise environments with mixed infrastructure, gradual MCP migration, multi-team organizations.

Pattern 4: Device-Local MCP

On-device LLM → Local MCP Server (stdio) → Hardware/Sensors

Everything runs on-device. The LLM, MCP server, and tools are all local. No network dependency.

Best for: Privacy-sensitive applications, offline environments, IoT devices, robotics.

When to Use Edge MCP vs. Centralized

The hybrid approach is most common in production. Edge handles latency-sensitive processing and device interaction; centralized handles batch analytics, model training, and compliance-heavy workflows. Gateway patterns (Envoy, ContextForge) federate both tiers under a unified MCP interface.

MCP Specification Features That Enable Edge

The spec has moved fast on this front — the picture below reflects the 2026-07-28 specification revision, the current version as of this update, which changed several of the mechanics edge deployments care about most.

Streamable HTTP — Single HTTP endpoint using HTTP POST/GET, introduced in specification version 2025-03-26 to replace the older HTTP+SSE transport. This transport was designed for serverless and edge deployment. See our MCP on Serverless guide for transport details. Two mechanics edge operators may remember from earlier versions were removed in 2026-07-28: the Mcp-Session-Id header and protocol-level sessions (superseded by explicit, server-minted state handles passed as ordinary tool arguments), and SSE stream resumability via Last-Event-ID (a broken response stream now means the client re-issues the request with a new request ID rather than resuming the old one).

Stateless by default — The 2025-03-26 spec offered stateless mode as an option; the 2026-07-28 revision made it the protocol’s baseline behavior by removing the initialize/notifications/initialized handshake entirely (SEP-2575). Every request now carries its own protocol version and capabilities, so there’s no connection-scoped setup step to keep pinned to one edge instance — a direct win for horizontal scaling across edge locations.

Async Tasks moved to an extension — The task-tracking mechanism for long-running server work (useful for querying status from any edge location) shipped inside the core spec in the 2025-11-25 revision, but the 2026-07-28 revision moved it out into an official extension (io.modelcontextprotocol/tasks) with a redesigned polling-based API (SEP-2663). The general extensions mechanism itself (for edge-specific additions outside the core spec) and continued OAuth authorization hardening for distributed auth are both part of the current spec.

Getting Started

If you’re considering edge MCP deployment:

1. Start with Cloudflare Workers if you need the most mature platform with stateful session support. The Agents SDK’s McpAgent class handles transport, sessions, and scaling.

2. Choose Fastly Compute if security isolation is your primary concern. WASM sandboxing provides the strongest tool execution boundaries.

3. Use wasmcp if you want portability across edge runtimes. Write once in Rust/Python/TypeScript, deploy to any WASI-compatible edge.

4. Try MCP over MQTT if you’re integrating IoT devices on constrained networks where HTTP overhead is prohibitive.

5. Consider the SLM-LLM bridge if you need on-device intelligence with cloud fallback. The cost savings (10-30x) justify the architectural complexity.

6. Default to centralized if your use case doesn’t have latency, sovereignty, or offline requirements. Edge deployment adds operational complexity — only adopt it when the benefits justify the cost.

What’s Coming

The edge MCP ecosystem is evolving rapidly:

• MCP specification — The stateless-by-default push tracked here as a proposal (SEP-1442) has already shipped: the 2026-07-28 specification revision removed the initialize handshake and made every request self-describing (SEP-2575), which is exactly the edge-deployment simplification this was aiming at
• WASM ecosystem — MCP.run’s planned serverless execution and wasmcp’s growing middleware library will make WASM MCP more accessible
• Edge AI hardware — Qualcomm Snapdragon NPU (45 TOPS), Apple Neural Engine, and Google Edge TPU will make on-device MCP + local inference increasingly practical
• Protocol transports — MCP over MQTT is just the beginning; expect MCP over CoAP, BLE, and other IoT protocols
• Gateway convergence — Projects like IBM ContextForge are federating MCP, A2A, REST, and gRPC under unified gateways, making edge routing simpler
