MCP for AI agents
MCP is gatOS’s agent interface. It exposes the same snapshots and command queue as the other transports, but groups them into logical resources and tools such as world, celestial, vessel, kitten, runtime, controls, batches, schedules, camera, audio, FX, and paint.
The default local endpoint is:
http://127.0.0.1:4243/mcpIt is Streamable HTTP and binds to loopback by default. Set mcp_bind_host to another IP or
0.0.0.0 for all IPv4 interfaces. There is no guest endpoint, bearer token, CORS policy, or legacy
SSE transport in MCP v1, so a non-loopback bind exposes the endpoint to reachable clients. Start
with gatos.get_capabilities, then discover vessels and read a fresh snapshot before sending a
narrow command.
MCP is deliberately not a path-for-path /sim copy. It uses raw KSA IDs, structured JSON, and
logical actions. /sim/display is intentionally outside MCP v1 because a terminal image stream is a
poor substitute for an agent-readable world model.
