Does Odoo 20 have MCP built in?
Yes. Odoo 20 Enterprise includes a native MCP module called ai_mcp, which exposes a single /mcp endpoint speaking JSON-RPC 2.0 against MCP spec revision 2025-11-25. It auto-installs on any Enterprise 20 database that already has the AI module. It is not available on Odoo Community, and it does not exist in Odoo 14 through 19.
