WunderGraph builds Cosmo, an open-source GraphQL federation platform for managing supergraphs, routing, schema registry, and analytics. It is offered as both self-hosted software and a managed cloud service.
WunderGraph exposes a developer CLI (`wgc`) and two MCP surfaces: a local stdio Cosmo MCP Server via the CLI, plus the Cosmo Router MCP Gateway; both are part of its GraphQL federation platform docs, with API-key auth confirmed for the CLI-based surfaces and router-gateway auth/config documented but endpoint mechanics not fully exposed in the public docs reviewed.

Create an API key in Cosmo Studio following the steps on API Keys. The CLI docs state API keys are required for wgc, and you then provide it as COSMO_API_KEY.
