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.
