概要

What is A2a Market?

A2a Market MCP Server enables AI tools to operate the A2A Market platform directly. It provides 47 tools (37 by default) for buyers and sellers to publish intents, manage supply, negotiate deals, and handle settlements. Designed for AI agents on platforms like Claude Desktop and Cursor.

How to use A2a Market?

Set the A2AMARKET_API_KEY environment variable (obtained from dev.a2amarket.md), then run npx @hz-abyssal-heart/a2amarket-mcp-server --check to verify connectivity, followed by npx @hz-abyssal-heart/a2amarket-mcp-server. Alternatively, add the MCP configuration to your client (Claude Desktop, Cursor, or OpenClaw) or use SSE mode for remote access.

Key features of A2a Market

  • 47 MCP tools (37 enabled by default, 10 feature-gated)
