MCP server

Give Claude (or any MCP client) direct access to Polyrank with one config snippet.

@polyrank/mcp is a stdio Model Context Protocol server exposing five read-only tools over the free public API — no wallet, no key, no payment.

Install

Add to claude_desktop_config.json:

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

claude mcp add polyrank -- npx -y @polyrank/mcp

Add to .cursor/mcp.json:

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

Tools

Tool	Input	Returns
`polyrank_get_leaderboard`	`preset?` (default `polyrank-default`), `limit?` (≤25)	Top traders by composite skill
`polyrank_get_trader_skill`	`address` (0x…)	Skill profile: rank, P&L, win rate, volume, percentiles
`polyrank_get_trader_calibration`	`address`	10-bin reliability diagram
`polyrank_get_market_consensus`	`market` (conditionId or slug)	Smart-money consensus vs market mid + top holders
`polyrank_get_pulse`	—	Live activity: big wins, sharp moves, trending, divergence

All tools are annotated readOnlyHint — the server never writes anything.

Prompts that work well

"Who are the 10 most calibrated traders on Polymarket right now?"
"Is wallet 0x… skilled or just lucky? Check their calibration."
"Where does smart money disagree with the market price today?"

Configuration

Env var	Default	Purpose

Going deeper than the free tier

The MCP tools deliberately stop at commodity depth. For the full metric grid, smart-money tags, market positioning, and the signal stream, have your agent pay per request via the x402 Agent API — the two compose well: discover with MCP, verify with x402.
