README

mcp-starter

Secure, starter MCP server boilerplate with JWT authentication, schema validation, and Docker support.

Built for developers who want to expose AI-compatible APIs to tools like Claude, OpenAI, Sourcegraph Cody, or custom agents using the Model Context Protocol (MCP).

Features

JWT-based authentication with tenant isolation
Function auto-loading from /functions directory
Inline per-function schema validation (via AJV)
Dynamic MCP manifest generation (/mcp-manifest.json)
Docker container
CLI utility to generate JWTs for local testing
Health endpoints (/mcp, /healthz)

Running locally

Clone repo

git clone https://github.com/parmindersk/mcp-starter.git
cd mcp-starter

Run with Docker

docker-compose up

Run from code

pnpm install
pnpm start

Generating a Test Token

node tools/generateToken.js --tenant=acme --secret=supersecure

The --secret value (supersecure) must match the JWT_SECRET defined in your .env or docker-compose.yml.

Testing sample submitFeedback

curl -X POST http://localhost:3000/mcp \
  -H "Authorization: Bearer YOUR_JWT_HERE" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "submitFeedback",
    "params": {
      "message": "Love the product!",
      "rating": 5
    }
  }'

You can play around with the body to remove message or give an invalid value for rating to see how validation is working.
