> A community index of open-source Codex, Claude Code, and Agent Plugins packages containing agent skills and MCP servers.

The index is built from public GitHub repositories that declare a valid canonical runtime manifest. It is a discovery index, not the publisher of the listed plugins.

## Canonical pages

- [Home](https://pluginsmp.com/) — definition, registry totals, and featured plugins.
- [Browse plugins](https://pluginsmp.com/plugins) — searchable, filterable plugin index.
- [Categories](https://pluginsmp.com/categories) — manifest-keyword categories with counts.
- [Timeline](https://pluginsmp.com/timeline) — plugins ordered by when they entered the index.
- [API and MCP documentation](https://pluginsmp.com/docs) — endpoint contract and examples.
- [Full LLM catalog](https://pluginsmp.com/llms-full.txt) — text summary of every indexed plugin.

## REST API (JSON, read-only, no auth)

- GET https://pluginsmp.com/api/v1/plugins — search the index. Repeat protocol to match any selected runtime (codex|claude-code|agent-plugins); other params: q, category, type (skills|mcp), transport (stdio|streamable-http|sse), sort (stars|updated|recent), page, per_page (1-50, default 24).
- GET https://pluginsmp.com/api/v1/plugins/{slug} — full detail for one plugin: manifest, skills, MCP server configs. No params.
- GET https://pluginsmp.com/api/v1/categories — keyword-derived categories with plugin counts. No params.
- GET https://pluginsmp.com/api/v1/stats — registry totals: plugins, skills, MCP servers, categories. No params.

## MCP endpoint

- POST https://pluginsmp.com/api/mcp — streamable-http transport, stateless (no session, single JSON-RPC messages).
- Tools: search_plugins (query/protocol as one runtime or runtime array/category/type/transport/sort/page/per_page), get_plugin (slug), get_stats.
