Yes, hosted, at /mcp on your instance: JSON-RPC 2.0 over streamable HTTP, protocol 2025-06-18. Any MCP client, Claude Code, Claude Desktop, Cursor, Windsurf, Codex, can list and call Heidi's tools with a bearer token.
MCP is how your AI tools read the company brain: memory search, entity lookups, and the ask_heidi tool that runs a full agent turn. Scopes apply exactly like REST, so a default token cannot touch anything side-effecting.
Your instance serves paste-ready config blocks for each client, and the docs live at falkster.ai/developers/mcp.
