Connect

Any client that supports remote MCP servers:

{ "mcpServers": { "mcp-harbor": { "url": "https://mcpharbor.app/mcp" } } }

For stdio-only clients, use a bridge such as mcp-remote: {"command":"npx","args":["mcp-remote","https://mcpharbor.app/mcp"]}.

Try it with curl

curl -s https://mcpharbor.app/mcp -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_tools","arguments":{"query":"postgres"}}}'

Self-host

No dependencies and no build step. src/mcp.js is the protocol and search logic. src/worker.js is a Cloudflare Worker entry point that loads the directory dataset from DATA_URL.

Development

npm ci && npm run check runs ESLint, a strict TypeScript check of the JSDoc-typed JavaScript (tsc, checkJs), and the node:test suite (fixtures only, no network). GitHub Actions runs the same on every push and pull request.
