TheGraph MCP Server powers AI agents with indexed blockchain data from The Graph. It exposes two primary tools: getSubgraphSchema, which fetches the schema of a specified subgraph (with an asText flag to return a human-readable GraphQL schema or default JSON schema), and querySubgraph, which executes GraphQL queries against a specified subgraph (allowing AI-generated or manual queries). The server is designed to enable AI workflows by providing the necessary context to construct and execute subgraph queries. The README includes installation steps (clone the repository) and a client configuration example for registering the MCP server under the name "thegraph-mcp" with a command, arguments, and an environment variable THEGRAPH_API_KEY for authentication. It runs with Python 3.10+ as indicated by the badges. Example prompts demonstrate schema queries, data queries, analysis tasks, and combined tasks to guide usage. Overall, this MCP server enables AI agents to access and query blockchain data via The Graph subgraphs efficiently within MCP workflows.
