Overview
A Model Context Protocol (MCP) server that connects to Heurist Mesh APIs, providing Claude with access to various blockchain and web3 tools. Heurist Mesh is an open network of purpose-built AI agents and tools, each specialized in domains such as blockchain data analysis, smart contract security, token metrics, and blockchain interactions. The server loads a suite of tools, including commonly used agents like CoinGeckoTokenInfoAgent, ElfaTwitterIntelligenceAgent, ExaSearchAgent, DexScreenerTokenInfoAgent, and ZerionWalletAnalysisAgent, enabling integrated workflows across crypto data, sentiment analysis, web searches, and security reviews. A hosted SSE endpoint is provided at sequencer-v2.heurist.xyz/mcp/sse, and the service supports both Server-Sent Events and stdio transports to accommodate Cursor and Claude Desktop, as well as other MCP-compatible interfaces. Prerequisites include Python 3.10 or higher, UV package manager (recommended), or Docker, and a Heurist API key. Installation can be performed via UV or Docker, with usage examples for stdio and SSE modes. The full toolset is viewable at mesh.heurist.ai/metadata.json or mcp.heurist.ai, and agents to expose can be customized by editing DEFAULT_AGENTS in server.py.
