About @modelcontextprotocol/fastify
@modelcontextprotocol/fastify
Fastify adapters for the MCP TypeScript server SDK.
This package is a thin Fastify integration layer for @modelcontextprotocol/server.
It does not implement MCP itself. Instead, it helps you:
• create a Fastify app with sensible defaults for MCP servers • add DNS rebinding protection via Host header validation (recommended for localhost servers)
Install
Exports
• createMcpFastifyApp(options?) • hostHeaderValidation(allowedHostnames) • localhostHostValidation()
Usage
Create a Fastify app (localhost DNS rebinding protection by default)
Streamable HTTP endpoint (Fastify)
To reject non-POST requests with 405 Method Not Allowed, add routes for GET and DELETE that send a JSON-RPC error response.
Host header validation (DNS rebinding protection)
