Overview
What is Starknet MCP Server?
A comprehensive Model Context Protocol (MCP) server for the Starknet blockchain. It provides AI agents with the ability to interact with Starknet networks, query blockchain data, manage wallets, and interact with Cairo smart contracts. Designed for use with Claude, GPT, and other AI assistants.
How to use Starknet MCP Server?
Run the server in stdio mode (npx @mcpdotdirect/starknet-mcp-server) or HTTP mode (npx @mcpdotdirect/starknet-mcp-server http). Install via Smithery, npx, npm global, or local project installation. Connect from Cursor by adding a command-type MCP server or via .cursor/mcp.json. Use claude mcp add starknet-mcp-server npx @mcpdotdirect/starknet-mcp-server for Claude CLI.
