TheGraph MCP Server

An MCP server that powers AI agents with indexed blockchain data from The Graph.

Available Tools

1. getSubgraphSchema

Fetches the schema of a specified subgraph, providing AI agents with the context needed to generate GraphQL queries.

Parameters:

• subgraphId: The subgraph ID (e.g., "QmZBQcF...")

• asText: Output format flag

  • true: Returns human-readable GraphQL schema

  • false: Returns JSON schema (default)

2. querySubgraph

Executes GraphQL queries against a specified subgraph. While queries are typically generated by AI, you can also manually craft your own.

Parameters:

• subgraphId: The subgraph ID

• query: GraphQL query string

Example Prompts

Here are some natural language prompts to trigger the tools:

Schema Queries

• "Show me the schema for subgraph QmZBQcF... in a readable format"

• "What's the structure of the QmZBQcF... subgraph? Please display it in GraphQL format"

• "I need to understand the data model of subgraph QmZBQcF..., can you fetch its schema?"

Data Queries

• "Find the top 5 tokens by trading volume in the last 24 hours from subgraph QmZBQcF..."

• "Show me all pairs with liquidity greater than 1 million USD in subgraph QmZBQcF..."

• "Get the latest 10 swap events from the QmZBQcF... subgraph, including token symbols and amounts"

Analysis Tasks

• "Analyze the trading volume of USDT pairs in the last week using subgraph QmZBQcF..."

• "Compare the liquidity of ETH and USDC pairs in subgraph QmZBQcF..."

• "Find unusual trading patterns in the last 24 hours from subgraph QmZBQcF..."

Combined Tasks

• "First get the schema of QmZBQcF..., then help me write a query to find high-value transactions"

• "Check the schema of QmZBQcF... and tell me what fields are available for querying token prices"

• "Using subgraph QmZBQcF..., analyze the market impact of large trades by first understanding the schema and then querying relevant events"
