A2A and MCP

The two open protocols Cremind speaks — A2A for pluggable agents and MCP for pluggable tools.

Cremind avoids proprietary plumbing by speaking two open protocols: A2A (Agent-to-Agent) for pluggable agents and MCP (Model Context Protocol) for pluggable tools. Plug in any MCP server to give the agent new capabilities, or connect other agents over A2A — both arrive in the same unified tool registry the reasoning loop calls into, alongside the intrinsic, builtin, and skill tools.

Documentation in progress

This page is being written. For now, see the source on GitHub at cremind-ai/cremind, and the related page The Tool Plane for how A2A and MCP tools fit into the unified registry.

The Tool Plane

Cremind's unified tool registry spanning intrinsic, builtin, A2A, MCP, and skill tools — one surface the reasoning loop calls into.

Document RAG

How Cremind indexes markdown you drop into a watched folder and retrieves it on demand through the documentation_search tool.
