Anthropic's MCP Registry

TODO: Review Ingestion Theory

Guha/Team: Please review the ingestion and superset mapping theory for this ecosystem integration before finalized publication.

Agent Finder acts as an open, protocol-agnostic discovery envelope designed to ingest, wrap, and index the Model Context Protocol (MCP) tool ecosystem.

The Envelope Mapping

The Model Context Protocol (MCP) standardizes model-to-data/tool connections. Agent Finder wraps MCP tool server endpoints under the standard application/mcp-server+json media type:

{
  "identifier": "urn:ai:acme.com:server:weather",
  "displayName": "Acme Weather Telemetry Server",
  "type": "application/mcp-server+json",
  "url": "https://api.acme.com/mcp/weather.json",
  "capabilities": ["WeatherTool", "ForecastTool"],
  "representativeQueries": [
    "what is the current wind speed in Chicago",
    "get the 5-day forecast for Seattle"
  ]
}

Developer Value

  • Federated Scaling: Developers of private or enterprise MCP tools can bypass the centralized modelcontextprotocol.io registry altogether and host their servers sovereignly on their own FQDNs.
  • Zero Prompt Bloat: By indexing representativeQueries outside the prompt, clients (like Claude Code) can perform semantic vector searches on the registry first, feeding Claude only the top matching tool schemas dynamically at runtime.
