Payanagent

Overview

Payanagent is a Model Context Protocol server that connects AI agents to a marketplace of over 24,000 live x402 services purchasable with USDC on Base. Any MCP-compatible AI assistant can invoke Payanagent's tools directly, letting the model decide when to access these services during conversations or agent runs.

The server runs locally via the npm package @payanagent/mcp, which communicates over stdio. Install it with npx -y @payanagent/mcp. You'll need an API key to authenticate. The latest release is v0.4.1, distributed under the MIT license with source code available at derNif/payanagent on GitHub.

Payanagent appears in the AI & Agents category and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim your listing on mcp.site to verify ownership and keep information up to date.
