## Registry-compatible endpoint

GET https://api.agentage.io/api/mcp/v0.1/servers mirrors the official MCP registry list contract (subregistry
pattern): a { servers: [{ server, _meta }], metadata } envelope with cursor pagination and
updated_since. Our enrichment (grades, categories, health, downloads, detail url) rides under
the _meta key "io.agentage.catalog/v0". See https://modelcontextprotocol.io/registry/registry-aggregators.
