"An introduction to Neo4j, a graph database management system" matching MCP servers:

MCP server that exposes unified AI-friendly tools over Messari's standardized lending subgraphs on The Graph. One natural-language query → fan out across 40+ lending protocols on multiple chains → get back structured, comparable data.

MCP server for querying Lido liquid staking protocol data via The Graph's decentralized network, providing tools for staking stats, APR, withdrawals, node operators, and governance.

Provides a unified MCP interface over Uniswap V2, V3, and V4 across multiple chains via The Graph, enabling agents to query token prices, top pools, pairs, and recent swaps with clean JSON output.

MCP server for querying AAVE V2/V3 lending protocol and governance data via The Graph subgraphs. Exposes 14 tools and 5 guided prompts that any AI agent (Claude, Cursor, Copilot, etc.) can use to query lending markets, user positions, health factors, liquidations, flash loans, rate history, and AAVE governance — across 7 chains (Ethereum, Base, Arbitrum, Polygon, Optimism, Avalanche, Fantom) via

An MCP server that enables querying Polymarket prediction market data through The Graph subgraphs. It provides tools for accessing market stats, trader P\&L, user positions, and orderbook activity using AI agents.

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

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Enables AI agents to query live on-chain data from The Graph's decentralized network with built-in verification and computed risk insights for Uniswap V3 pools, such as swap counts, directional flow, and concentration signals.

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

Enables querying Base Network blockchain data including blocks, transactions, balances, and smart contracts on mainnet and testnet.

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

A Model Context Protocol server for creating, updating, and querying semantic relationships (cyberlinks) on Cosmos-based blockchains through integration with Cursor IDE and Claude Desktop.

An AI-driven platform for analyzing Polymarket prediction markets using on-chain data, offering smart money tracking, sentiment analysis, and arbitrage detection via natural language queries.

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

Provides comprehensive access to the Ethereum Follow Protocol (EFP) API, enabling social graph queries, follower/following management, ENS resolution, and profile data retrieval for Ethereum addresses and ENS names.

Enables AI agents to interact with the AI Network blockchain by managing accounts, submitting transactions, and reading database values. It supports registering Hyper Agents and accessing a Layer 2 DAG-based shared agent memory system based on staking status.

Provides complete HTTP/JSON access to all 100+ Emercoin RPC endpoints with integrated formatting utilities. Enables blockchain operations, name system management, wallet functions, and mining operations through a comprehensive REST API interface.

Enables querying Polymarket prediction market data, including top active markets and order books, without an API key or database.

Provides LLM access to Unicity gaming platform games through a payment-gated day pass system. Supports game discovery, access management, and payment processing via Nostr protocol and Unicity blockchain.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.
