Mcp is a Model Context Protocol (MCP) server: 575+ agent tools: data, AI gateway, storage/queues/watchers. x402 USDC, no keys, usage billing. Because it speaks the Model Context Protocol, AI assistants can use Mcp as a set of callable tools instead of you copy-pasting between apps.
It runs locally: the npm package @2sio/mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need EVM_PRIVATE_KEY. The current release is v1.82.0, published under the MIT license, with source at 2s-io/sdk on GitHub.
On mcp.site, Mcp sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
