Yieldagentx402

Overview

Yieldagentx402 is a Model Context Protocol (MCP) server: Policy-gated x402 MCP for agent workflows with TEE receipts, 18 tools, and no custody. Because it speaks the Model Context Protocol, AI assistants can use Yieldagentx402 as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package agentx402-mcp-server speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need YAX_API_KEY, YAX_AGENT_ID. The current release is v1.0.4, published under the MIT license, with source at Fabio662/yieldagentx402-sdks on GitHub.

On mcp.site, Yieldagentx402 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.
