@agentscore/mcp

MCP server for AgentScore — check AI agent reputation scores, trust levels, and ecosystem stats in the x402 network.

Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Tools

| Tool | Description | |------|-------------| | check_score | Look up an agent's reputation score by wallet address | | check_trust | Quick pass/fail trust check against a minimum threshold | | get_leaderboard | Top-scored agents in the x402 ecosystem | | get_ecosystem_stats | Network-wide transaction and agent statistics |

Quick Start

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "agentscore": {
      "command": "npx",
      "args": ["-y", "@agentscore/mcp"],
      "env": {
        "AGENTSCORE_API_KEY": "your-gateway-key-optional"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "agentscore": {
      "command": "npx",
      "args": ["-y", "@agentscore/mcp"]
    }
  }
}

Run directly

npx @agentscore/mcp

Environment Variables

| Variable | Required | Description | |----------|----------|-------------| | AGENTSCORE_API_KEY | No | Gateway key to bypass x402 payment for score lookups | | AGENTSCORE_API_URL | No | Override API base URL (default: https://pylon-reputation.fly.dev) |

How It Works

AgentScore indexes x402 payment transactions on Base to build reputation profiles for AI agents. Each agent gets a score (0-100) based on:

• Transaction volume — how active the agent is
• Success rate — reliability of payments
• Consistency — regular activity over time
• Longevity — how long the agent has been active
• Diversity — breadth of services used

The check_score tool queries the reputation API (x402-payable at $0.001, or free with a gateway key). Leaderboard and stats endpoints are free.
