README

Agent Referee MCP server

Let any MCP-capable agent use Agent Referee: a neutral tie-breaker between agents from different owners, and sealed review of one agent's own work, with Ed25519-signed receipts.

Works with Claude Desktop, Claude Code, Cursor, and any other client that runs MCP servers over stdio. The free tools need no wallet and no account.

What it's for: Agent Referee is for technical evaluation of AI agents' work; it isn't for deciding legal claims, contractual disputes or anyone's rights; results are advisory.

Paid use can be paused by the service. While it is, a paid call is refused before any payment, so nothing is charged, and the free tools keep working; the service's front page says when it's paused.

Tool	What it does	Cost
`demo_match`	Runs a complete tie-break in one call, playing both seats, so you can see how it works.	Free
`tiebreak`	Settles a deadlock with another agent. Both agents call it with the same `key` and settings; neither side nor the service can steer the result.	Free demo for now (paid tiers next)
`sealed_review`	Independent AI reviewers check your agent's output against its task, and return a verdict plus a signed receipt you can hand to whoever receives the work.	Free: 3 reviews and 1 `review-3` a day per address (no wallet). Then $0.05, or $0.20 for `review-3` (three reviewers from three AI companies). Work in 2 or 3 pieces: $0.60 (`review-3x2`) or $0.70 (`review-3x3`), paid only
`verify_receipt`	Checks any Agent Referee receipt offline against the pinned signing key. Pass the task and output (or the pieces, for a multi-part review or judge match) to confirm a receipt is about exactly that work.	Free
`review_result`	Returns a `sealed_review` that was still running when its call came back (`status: "running"`, a `job_id`).	Free
`saved_receipts`	Lists the review receipts this server saved on your machine, and today's spend.	Free

Set it up

You need Node.js 18 or newer.

Claude Desktop

Open Settings → Developer → Edit Config and add this to claude_desktop_config.json, then restart Claude Desktop:

{
  "mcpServers": {
    "agent-referee": {
      "command": "npx",
      "args": ["-y", "agent-referee-mcp"]
    }
  }
}

On Windows, if Claude Desktop can't start it, use "command": "cmd" and "args": ["/c", "npx", "-y", "agent-referee-mcp"].

Claude Code

claude mcp add agent-referee -- npx -y agent-referee-mcp

On Windows: claude mcp add agent-referee -- cmd /c npx -y agent-referee-mcp

Grok CLI (Grok Build)

grok mcp add agent-referee -- npx -y agent-referee-mcp

Restart the Grok session so it loads the server. The first call can take a few extra seconds while npx downloads the package.

Other MCP clients

Any client that runs local (stdio) MCP servers works the same way: the command is npx with the arguments -y agent-referee-mcp.

Try it

Ask your agent: "Use demo_match to run a free Agent Referee demo." It returns the winner, the signed receipt (marked demo), and the checks: the signature, each side's own seed, and the math.

Free sealed reviews

With no wallet set up, sealed_review uses the free daily allowance: 3 single-reviewer reviews and 1 review-3 per day from each address (IP address, or /64 block for IPv6), reset at 00:00 UTC. The operator pays for these, and one daily budget is shared by everyone, so free reviews can run out before the day ends. When they do, the tool says so.

Free receipts are signed exactly like paid ones and say "funding": "free", with no payer.
A busy service or a failed reviewer doesn't use up a free review.
With a wallet set up, reviews are paid unless the agent passes free: true.

Paid sealed review: add a wallet

sealed_review pays per review in USDC on Base over [x402
