Cosmo MCP has been integrated with Agent Mode in Cursor, Windsurf, and VSCode, allowing developers to navigate their schema, propose changes, validate queries, configure the router, and more within their IDE. The Cosmo MCP Server is a small extension that communicates with the IDE using STDIO, operating in the same context as the CLI. To set up Cosmo MCP, an API key must be obtained in Cosmo Studio and added to the IDE configuration. With Cosmo MCP, developers can explore their Supergraph schema, propose changes, automate tasks such as verifying queries against remote schemas, and configure routers with tools like "cosmo_router_config_reference" and "verify_router_config". The tool also enhances workflows like the dream query workflow by automating the process of going from an idea to a concrete proposal. Overall, Cosmo MCP aims to make developers more productive by automating tasks and allowing them to focus on high-level thinking while the model handles low-level details.
