An analysis of agent-native discovery for MCP.
A long-form essay with a live working prototype as the appendix. The writing examines where MCP server discovery is headed; the prototype demonstrates one possible answer.
The official MCP registry at registry.modelcontextprotocol.io is the canonical source of truth for MCP servers. Other directories — PulseMCP, Smithery, Glama, MCP.so — offer human-browsable views on top of it. mcpindex.ai explores the other view: machine-first, agent-callable, recommendation-shaped.
The thesis: as IDEs and agents add MCP server discovery to their UX, somebody becomes the API the IDE calls when a user types /add mcp postgres. The registry is the data source. mcpindex.ai is one argument for what the recommendation surface on top of it could look like — quality-scored, semantically searchable, and shaped to be callable from inside an agent loop.
Three primitives are exposed as part of the demonstration: an agent-readable index, a recommendation API, and a drop-in MCP server. The full architecture and integration patterns are documented in /docs; the open scoring methodology is at /methodology.

Server data comes from the official MCP registry; quality scoring and semantic ranking are generated locally from public fields only.
