Delete a custom agent

DELETE

/api/agent-definitions/custom/{id}

• Production

Permanently deletes a custom specialist agent definition. The agent’s MCP connection assignments are also removed. The MCP hub cache is invalidated so the agent is no longer dispatched. Platform agents cannot be deleted. A delete cannot be undone, so an API key needs the agents:write scope and no brand or workspace restriction.
