Setup snapshot

git clone https://github.com/losfair/hn-mcp.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Usage

Development

npm run dev

Production

npm run build
npm start

The server will start on port 3000 (or PORT environment variable) and provide:

  • MCP SSE endpoint at /sse (requires Bearer token authentication)
  • MCP message endpoint at /message (requires Bearer token authentication)
  • Direct HTTP API endpoints for testing

Authentication

For MCP endpoints, use Bearer token authentication:

Authorization: Bearer dummy-bearer-token-12345

Testing with Claude.ai

  1. Start the server: npm run dev
  2. In Claude.ai, add the MCP server URL: http://localhost:3000/sse
  3. Use the Bearer token: dummy-bearer-token-12345

API Examples

Get a story with comments

curl "http://localhost:3000/api/item/1"

Get top 10 stories

curl "http://localhost:3000/api/stories/top?limit=10"

Get user profile

curl "http://localhost:3000/api/user/pg"
