Connecting an Agent

Connecting an Agent

MCP Harbor is itself an MCP server, so an agent can search the registry, read install instructions and submit servers without a browser.

• Endpoint: https://ai.mcpharbor.dev/mcp
• Transport: Streamable HTTP (stateless; POST only)
• Auth: none for searching and reading

Add it

Claude Code:

claude mcp add --transport http mcp-registry-search https://ai.mcpharbor.dev/mcp

mcp-registry-search is just the local label for your own config; use any name you like.

Any other client: add a remote server of type http with that URL. The MCP server directory shows the exact block for each client.

Tools

Tool	What it does
search_servers	Searches names, titles, descriptions, tags and tool names. Returns short summaries.
get_server	One server by exact name: its server.json, review status and install snippets.
submit_server	Adds a server. It is reviewed before appearing in search — see Publishing a Server.

Search before submitting, so you don't add a duplicate.

For LLMs that read instead of connect

llms.txt describes the site, the endpoint and the tools in plain text.
