Building MCP tools with GraphQL can simplify the development process and provide better tools for Large Language Model (LLM) interaction. A commonly recommended pattern is to create a simple tool for every Entity defined in an API endpoint, but this approach has limitations due to the need for additional code and deployment. GraphQL operations as MCP tools offer a better alternative by providing no writing tool code, allowing the graph to do the API orchestration, and enabling the addition of tools without code deployments. This approach enables rapid iteration, hot-reloading, and improved developer experience, making it an attractive solution for building MCP tools with GraphQL.
