AllMCPs Categories API

openapi: 3.2.0
info:
  title: AllMCPs Directory Categories API
  description: 'Public API for querying and managing Model Context Protocol (MCP) servers listed on AllMCPs. Designed for AI agents, LLM tool callers, and developer integrations.


    **Versioning & deprecation policy**: this spec is URL-versioned (`/api/v1/...`). Endpoints are additive within v1 — existing fields are not removed or repurposed without a version bump. If an endpoint is ever deprecated, responses will carry a `Deprecation: true` header (and, once a removal date is set, a `Sunset: ` header) for at least 90 days before removal, and the change will be announced at https://allmcps.com/blog. There is currently no deprecated surface in v1.


    **Auth**: most endpoints are public/unauthenticated (see each operation). Listing-mutating agent actions require a scoped Bearer token — see `components.securitySchemes.agentBearerAuth` and https://allmcps.com/auth.md.'
