AsyncAPI MCP Server

An MCP (Model Context Protocol) server that gives AI assistants access to the AsyncAPI specification. Search, explore, and retrieve any version of the spec directly from your coding tool.

Try it in your browser on Glama — no installation required.

Features

• Search the AsyncAPI specification by keyword

• Retrieve specific sections by heading or slug

• List all stable spec versions available as GitHub tags

• Get metadata about the spec (version, source, cache info, size)

• Version-aware — query any released spec version, or default to the latest

• Caching — ETag/Last-Modified-based HTTP caching with a 10-minute TTL on tag lookups

Quick Start

Remote (Glama)

Use the hosted server on Glama — no local setup needed. Add the following to your MCP client configuration:

{
  "mcpServers": {
    "asyncapi": {
      "url": "https://glama.ai/mcp/servers/Souvikns/asyncapi-mcp"
    }
  }
}

See the Configuration section below for client-specific instructions.

Local (Self-hosted)

Prerequisites

• Node.js v20 or later

Install

npm install

Build

npm run build

Run

Streamable HTTP (for local development):

npm run dev

The server starts on http://localhost:3000/mcp by default. Set the PORT environment variable to use a different port:

PORT=8080 npm run dev

Stdio (for deployment):

npm start

Deployment

This server is deployed on Glama.ai. See glama.ai/mcp/servers/Souvikns/asyncapi-mcp for the hosted instance.

To deploy your own instance, build and run with stdio transport:

npm run build
npm start

A Dockerfile is included for containerized deployments:

docker build -t asyncapi-mcp .
docker run -p 3000:3000 asyncapi-mcp

Usage Examples

Once configured, you can ask your AI assistant questions like:

• "What does the AsyncAPI spec say about server objects?"

• "Search the AsyncAPI spec for 'channels'"

• "Get the Info Object section from version 2.6.0"

• "List all available AsyncAPI spec versions"

• "What are the differences between messages in AsyncAPI 2.x and 3.x?"

• "Show me the spec section about schema definitions"
