Query cryptocurrency market data (prices, market caps) via CoinMarketCap through Anthropic MCP.
2
Expose web3 functions (blockchain queries, wallet interactions) to the Claude client via a self-hosted MCP plugin.
3
A simple, local Node.js bridge so Claude can call custom web3 endpoints and scripts.

Description

This repository provides a lightweight Node.js MCP server implementation to let Claude (Anthropic) call web3-related functions. It includes build instructions and an example Claude desktop config showing how to register the server and provide environment variables like a CoinMarketCap (CMC) API key. The server is intended to be run locally or on a host you control, enabling Claude agents to access blockchain and crypto market data via an MCP plugin interface.
