"An introduction to GraphQL or resources for learning GraphQL" matching MCP servers:

Query the Sui blockchain directly from Claude using GraphQL.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Trace hidden insider wallet clusters behind Solana tokens before you ape — safety score, honeypot & LP-lock check, no signup for first 5 calls/day.

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

9 tools, Lightning-gated. Pay per call. For agents that need verifiable signed actions with an audit trail. Nostr event signing via daemon Publish events to relays Create Lightning invoices Action receipts — signed proof of agent actions Identity attestation

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

23 tools for AI agents working with Nostr Open source. No API key. No account. NIP-46 remote signing Publish notes, reply, react, repost Encrypted DMs (NIP-04 + NIP-44) Fetch events, profiles, social graph

A remote MCP server that links World ID 4.0 sessions to AI assistants, enabling verified human authentication and tools for claiming Founding Human places, accessing human grants, and interacting with a verified human wall.

A Model Context Protocol server that enables Claude AI to interact with the Solana blockchain, allowing it to execute transactions, query accounts, manage wallets, get price predictions, trade tokens, and access various blockchain data sources.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Powers AI agents with indexed blockchain data from The Graph, enabling them to fetch subgraph schemas and execute GraphQL queries against blockchain data.

A local-first MCP server that enables AI agents to query the Sui blockchain using gRPC, GraphQL, and Archival Service, with auto-routing and LLM-friendly responses.

Enables AI systems to fetch machine learning inferences and prediction market data from the Allora Network through the Model Context Protocol.

A server that allows AI agents to interact with the Tally API to access DAO governance data, proposals, and metadata using Model Context Protocol (MCP), built with TypeScript and GraphQL.

A Model Context Protocol server for Snapshot that lets AI assistants read governance data and act on the user's behalf through Snapshot's GraphQL API.

MCP server for a pre-interaction risk check on any EVM contract/token, enabling agents to verify contracts before approving, swapping, or trusting an address.

A read-only MCP server for AI agents to access Nostr profiles, notes, search, and relay lists through user-chosen relays, without requiring an account or keys.

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

A Model Context Protocol (MCP) server that provides tools and resources for AI agents to interact with the Algorand blockchain.
