Minimal MCP server for discovering and calling ERC8004 agents with x402 payment integration. Find agents by skill, retrieve agent cards, and execute agent calls with Coinbase payment signing.

What it does

Claynsn/agent-discovery-mcp is a lightweight Model Context Protocol (MCP) server (~250 lines of TypeScript) that enables discovery and interaction with ERC8004 agents on a decentralized network. It provides three core tools for agent discovery, card retrieval, and payment-enabled agent calls using x402 payment standards and Coinbase's official x402fetch.

How to set up

1. Clone the repository from GitHub (Claynsn/agentdiscoverymcp). 2. Install dependencies using npm or yarn. 3. Configure your EOA (Externally Owned Account) for direct signing. 4. Set up Coinbase credentials for x402 payment handling. 5. Run the MCP server and connect it to your AI client (Claude, ChatGPT, or other MCP-compatible platforms).
