MCP connections

MCP connections expose tools from a remote Model Context Protocol server to an agent. Register the endpoint in Central Hub, test it to discover its tools, then attach its connection ID to enabled_mcp_connection_ids.

An MCP connection includes a URL, transport, authentication mode, encrypted credentials, and scope_visibility (private or space). Use the MCP endpoints to create, update, delete, test, and refresh discovered tools. Rotate credentials through the connection instead of embedding secrets in prompts or skills.
