multichain-mcp is the only MCP server that gives AI agents native access to Stacks, Celo, and Base from a single npm package — no RPC keys required. 5 production-ready tools across 3 chains: → get_balance & get_prices — Free → get_portfolio & prepare_transfer — Pro ($9/mo) → deploy_token on Celo & Base — Team ($29/mo) All write operations return unsigned transactions — non-custodial by design. Works with Claude Desktop, Cursor, and Windsurf out of the box.
