What is the The Graph (Web3 Indexing) MCP Server?

Connect to The Graph to index and retrieve real-time blockchain data across multiple ecosystems. This MCP server allows your AI agent to query decentralized data from Ethereum, Polygon, Solana, and more through standardized tools and custom GraphQL subgraphs.

What you can do

EVM Data Access — Retrieve token transfers, top holders, and DEX swap events (Uniswap, Curve) for any EVM-compatible chain.
Solana (SVM) Integration — Fetch SPL token transfers, holders, and AMM swaps (Jupiter, Raydium) directly from the Solana network.
Historical Analysis — Access wallet balance changes in OHLCV format to track portfolio performance over time.
Custom Subgraph Queries — Execute raw GraphQL queries against any specific subgraph ID for deep, specialized data extraction.
Market Intelligence — Monitor liquidity pool activities and token distribution metrics without manual block explorer searching.

How it works

Subscribe to this server
Enter your The Graph API Token, API URL, and optional API Key
Start querying on-chain data from Claude, Cursor, or any MCP-compatible client

Who is this for?

Web3 Developers — debug smart contract events and verify on-chain state directly from your IDE
Data Analysts — aggregate token holder distributions and DEX volume metrics for research
DeFi Power Users — track wallet movements and liquidity pool swaps through natural language

FAQ

Frequently asked questions

Can I query any specific subgraph if I have its ID?

Yes! Use the query_subgraph tool by providing the subgraph_id and your GraphQL query string. This allows for deep, custom data extraction beyond the standard tools.

Does this server support Solana token data?

Absolutely. You can use get_svm_transfers, get_svm_holders, and get_svm_swaps to interact with SPL tokens and decentralized exchanges on the Solana network.

Can I track historical balance changes for a specific wallet?

Yes, the get_evm_historical_balances tool provides historical balance data in OHLCV format for EVM chains, making it easy to analyze portfolio trends.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
