Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)

Environment variables

  • WELLKNOWN_API_KEY secret Optional wk_live_ key for higher rate limits and owner tools.
  • WELLKNOWN_MCP_URL Endpoint to bridge to. Defaults to https://wellknown.network/mcp.

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

ToolWhat it does
search_agentsSearch by capability or plain-language need. Returns observed status and the ranking signals behind each hit.
resolve_agentGiven a task and constraints, returns ranked callable candidates and a recommendation with its evidentiary basis. Use this when you intend to call the result.
get_agentThe full record: declared metadata, derived capabilities, observed status, verification, provenance.
check_statusCurrent liveness, the reason for it, and a 30-day reliability summary. unknown means no evidence, never a guess.
list_capabilitiesThe capability taxonomy, for precise filtering.
submit_agentAnnounce an agent by its A2A card URL or an inline manifest.
claim_agent / verify_claimProve you control a record — DNS, a /.well-known/ file, or a repository file — and unlock owner edits, 15-minute checks and an owner API key.
index_statsTruthful counts: records, live endpoints, observations, last crawl.

Configuration

VariableDefaultPurpose
WELLKNOWN_MCP_URLhttps://wellknown.network/mcpEndpoint to bridge to.
WELLKNOWN_API_KEY—A wk_live_… key: higher rate limits and owner tools. Created in the dashboard or minted by a verified claim.
WELLKNOWN_TIMEOUT30000Per-request timeout in milliseconds.

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.

Frequently asked questions

What is network.wellknown/wellknown?

Live index of AI agents, MCP servers and tools with observed liveness and capability search.

How do I install network.wellknown/wellknown?

It runs as a remote server. In Claude Code: claude mcp add --transport http wellknown 'https://wellknown.network/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does network.wellknown/wellknown need an API key?

Yes. It expects WELLKNOWN_API_KEY, which you set in its configuration.

Is network.wellknown/wellknown open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains network.wellknown/wellknown?

It is published by sanemavcil. AI.tn lists it but does not maintain or endorse it.
