Run402 is a Model Context Protocol (MCP) server: x402 pay-per-call infra for agents: $0.03 image generation, Postgres, auth, storage, functions. In practice that means any MCP-compatible AI assistant can call Run402's tools directly — the model decides when to use them in a conversation or agent run.
You can run Run402 two ways: connect to the hosted endpoint at https://mcp.run402.com/mcp with no local install, or run it on your own machine via the npm package run402-mcp. The current release is v4.16.0, published under the MIT license, with source at kychee-com/run402 on GitHub, where it has earned 24 stars.
Run402 is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
