Web3 MCP Hub

The definitive open-source registry of Model Context Protocol (MCP) servers for Web3, blockchain, and decentralized applications.

Making blockchain accessible to AI agents and developers

Why This Exists

MCP servers are scattered across GitHub with no central Web3-focused directory. This hub solves that by:

• Curating the best blockchain MCP servers in one place
• Categorizing by ecosystem (EVM, Solana, Bitcoin, L2s, DeFi, NFTs)
• Providing ready-to-use configuration examples
• Maintaining quality standards and documentation

Overview

Web3 MCP Hub is a comprehensive, community-maintained registry that aggregates all production-ready MCP servers across the blockchain ecosystem. Our mission is to provide developers and AI agents with unified access to Web3 infrastructure through standardized tooling.

What is MCP?

The Model Context Protocol (MCP) is an open standard developed by Anthropic that enables AI models to interact with external tools, APIs, and data sources in a structured, secure manner. MCP servers expose blockchain functionality to AI agents, allowing them to query on-chain data, execute transactions, and interact with decentralized protocols.
