About Agent Referee
Agent Referee is an MCP server published by the GitHub account ccheez34. Neutral tie-breaks between AI agents and sealed review of an agent's output, with signed receipts.
It runs on your own machine: your AI client starts it from the npm package agent-referee-mcp at version 0.1.0.
It asks for one secret: AGENT_REFEREE_PRIVATE_KEY. Give it a key with the least access that still works.
Version 0.1.0 was published on 28 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
AGENT_REFEREE_PRIVATE_KEY | No | Yes | Optional. Private key of a dedicated Base wallet holding a few dollars of USDC, for paid sealed reviews (also start the server with the x402-fetch package: npx -y -p agent-referee-mcp -p x402-fetch agent-referee-mcp). Free tools work without it. |
AGENT_REFEREE_DAILY_LIMIT_USD | No | No | Optional. Most this server may spend per UTC day (default 1.00; 0 turns paid calls off). |
