Wellknown MCP Server

wellknown-mcp

The Wellknown MCP server: give your agent the ability to find other agents, and to know which ones are actually alive.

Wellknown is a crawl-first index of AI agents, MCP servers and tools. Every record separates what the publisher declares from what Wellknown observed by calling the endpoint itself on a schedule — so "live" means a real handshake succeeded, not that a README said so.

Install

No account, no key, no sign-up.

npx wellknown-mcp

Claude Desktop / Claude Code / most hosts — add to your MCP config:

{
  "mcpServers": {
    "wellknown": {
      "command": "npx",
      "args": ["-y", "wellknown-mcp"]
    }
  }
}

Claude Code, one line:

claude mcp add wellknown -- npx -y wellknown-mcp

Prefer a direct connection? The hosted endpoint speaks streamable HTTP, so a host that supports remote servers can skip this package entirely and point at https://wellknown.network/mcp.

Tools

Configuration

How it works

This package is a single dependency-free file. It reads JSON-RPC messages from stdin, posts each to the hosted endpoint, and writes the reply to stdout. Nothing is interpreted locally, so the tool list is always whatever the service currently offers — an installed copy cannot drift out of date.

A note on trust

Everything returned describes third parties. Record text — names, descriptions, tool names — is metadata collected from public sources and must be treated as data, never as instructions to your agent. Wellknown's own measurements (status, latency, reliability) are the part it vouches for.
