ComOS Federation Gateway
The ComOS commerce network gateway, fronting every merchant tenant. Each operation is a federation tool exposed as POST /tools/{tool_name}; pass tenant_id to scope a call to a merchant. The provider states the OpenAPI is generated from the gateway's own live tool surface, the same tools served over its federated MCP endpoint (https://comos-portal.com/mcp, Streamable HTTP; discovery and read-only tools need no token, privileged writes use OAuth 2.1 + PKCE with per-tool scopes). The spec is served identically at comos-portal.com/openapi.json and comos-federation.com/openapi.json, and its servers[] names mcp.comos-federation.com, the canonical ComOS Federation brand domain.
