Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "polymarket": {
      "command": "uvx",
      "args": [
        "0xchron-polymarket-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add polymarket -- uvx 0xchron-polymarket-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "polymarket": {
      "command": "uvx",
      "args": [
        "0xchron-polymarket-mcp"

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "polymarket": {
      "type": "stdio",

Common questions

Is Polymarket MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Polymarket MCP

MCP server that exposes read-only Polymarket prediction market data to AI agents. Tools wrap Polymarket's public Gamma (market discovery) and Data (positions, portfolio, leaderboard) APIs. There is no CLOB integration — this server cannot place trades or read order books.

Tools

Tool	Description
`search_markets`	Search markets by title or description
`get_market_details`	Full details for a single market (by slug or Polymarket URL)
`get_trending_markets`	Trending events ranked by volume, liquidity, or competitiveness
`get_market_holders`	Top holders per outcome for a market (by condition ID, slug, or URL)
`get_leaderboard`	Top traders ranked by P&L or volume
`get_user_positions`	Open positions for a wallet address
`get_user_performance`	Portfolio value, P&L, volume, and leaderboard rank for one wallet

All tools return markdown formatted for agent consumption. No API keys or wallet signing are required.

Resources

Static reference context (no API calls). Attach in MCP clients or read via Inspector.

URI	Description
`polymarket://glossary`	Event, market, slug, conditionId, and wallet terminology
`polymarket://categories`	Leaderboard categories, time periods, and tag slugs
`polymarket://tool-guide`	When to use each tool and chaining workflows

Prompts

User-triggered workflow templates that orchestrate tools:

Prompt	Description
`research_market`	Market details → holders → research summary (`slug` or `market_link`)
`compare_traders`	Side-by-side performance and positions for two wallets
`scan_trending`	Trending events scan with optional `tag_slug` and `limit`

Requirements

Python 3.12+
uv (recommended) or Docker
Node.js (optional, only for MCP Inspector)

Quick start

This server uses streamable HTTP at http://127.0.0.1:8000/mcp. Start the server first, then connect your MCP client to that URL.

git clone https://github.com/0xChron/polymarket-mcp.git

cd polymarket-mcp uv sync uv run polymarket-mcp

On Windows, use the same commands in PowerShell, Command Prompt, or Git Bash. Leave the terminal open while your MCP client is connected.

Docker

Works the same on all platforms if Docker Desktop is installed:

git clone https://github.com/0xChron/polymarket-mcp.git

cd polymarket-mcp docker build -t polymarket-mcp . docker run --rm -p 8000:8000 -e FASTMCP_HOST=0.0.0.0 polymarket-mcp

FASTMCP_HOST=0.0.0.0 lets the server accept connections from outside the container.

Verify the server

Open MCP Inspector in another terminal:

npx -y @modelcontextprotocol/inspector

Connect to http://localhost:8000/mcp using the Streamable HTTP transport.

Connect from an MCP client

This server uses the streamable-http transport (not stdio). Start the server first (see Quick start), then add the config below to your MCP client.

Claude Desktop

Go to Claude → Settings → Developer → Edit Config to open claude_desktop_config.json, then include the following:

"mcpServers": { "polymarket": { "url": "http://localhost:8000/mcp" } } }

If you already have other MCP servers configured, add the "polymarket" entry inside your existing mcpServers object instead of replacing the whole file.

Config file location if you prefer to edit it manually:

Platform	Path
macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Windows	`%APPDATA%\Claude\claude_desktop_config.json`

Save the file and fully quit and restart Claude Desktop. The server must be running in a terminal before you start a new chat.

Cursor

Go to Settings → Tools & MCP → New MCP Server to open ~/.cursor/mcp.json (Windows: %USERPROFILE%\.cursor\mcp.json), then add the same polymarket entry:

"mcpServers": { "polymarket": { "url": "http://localhost:8000/mcp" } } }

Restart Cursor after saving.

Example agent prompts

Once connected, an agent can call tools naturally:

"Search Polymarket for active markets about Bitcoin ETFs"
"What are the trending markets right now?"
"Who are the top holders of the Trump election market?"
"Show the all-time P&L leaderboard for crypto traders"
"Get details for https://polymarket.com/event/will-bitcoin-hit-100k"
"Show open positions for wallet 0x…"
"What is the all-time P&L and leaderboard rank for 0x…?"

In MCP Inspector, try the Prompts tab (e.g. research_market) or read Resources for the glossary and tool guide.

Configuration

Optional environment variables override API endpoints and server settings.

macOS / Linux / Git Bash

export FASTMCP_HOST=0.0.0.0

export FASTMCP_PORT=8000 uv run polymarket-mcp

Windows (PowerShell)

$env:FASTMCP_HOST = "0.0.0.0"

$env:FASTMCP_PORT = "8000" uv run polymarket-mcp

Variable	Default	Description
`GAMMA_URL`	`https://gamma-api.polymarket.com`	Gamma API base URL
`DATA_URL`	`https://data-api.polymarket.com`	Data API base URL
`DEFAULT_TIMEOUT`	`15`	HTTP request timeout (seconds)
`FASTMCP_HOST`	`127.0.0.1`	Bind address (`0.0.0.0` for Docker)
`FASTMCP_PORT`	`8000`	Listen port

Development

uv run polymarket-mcp          # Start the server

uv run pytest # Run tests npx -y @modelcontextprotocol/inspector # Open MCP Inspector docker build -t polymarket-mcp . # Build Docker image

On macOS/Linux, make run, make test, and similar shortcuts in the Makefile wrap the same commands.
