@pipeworx/the-graph

The Graph MCP — GraphQL queries against blockchain subgraphs.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• query_subgraph(subgraph_id, query, variables?) — run an arbitrary GraphQL query.

• introspect_schema(subgraph_id) — fetch the subgraph schema for query construction.

Related MCP server: TheGraph MCP Server

Auth

• Platform key: gateway env PLATFORM_THEGRAPH_KEY.

• BYO: ?_apiKey=<key> after signing up at https://thegraph.com/studio/apikeys (free 100k queries/month).

The legacy hosted service is gone; everything routes through the decentralized network gateway at gateway-arbitrum.network.thegraph.com.

Finding subgraph IDs

Browse https://thegraph.com/explorer. Each subgraph's "Query URL" ends in /subgraphs/id/<the-id-you-want>.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "the-graph": {
      "url": "https://gateway.pipeworx.io/the-graph/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about The Graph data" })

The gateway picks the right tool and fills the arguments automatically.
