Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account whitmorelabs for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Local MCP server giving an assistant Polymarket trading intelligence: slippage, liquidity, arbitrage and price feeds.

What you can do: Analyze Polymarket markets for slippage and liquidity.
Compare markets to surface arbitrage opportunities.
Read price feeds for prediction-market pricing.
No tool list is published, so the exact operations are not documented.
When to use it: Worth adding when you want an assistant to reason about Polymarket prediction markets — checking liquidity, estimating slippage, or looking for arbitrage between markets — from a local desktop setup.
Requirements: Runs as a local process over stdio, installed from the PyPI package polymarket-trading-mcp, so a Python environment is needed. No authentication, environment variables or headers are declared. Desktop only; not available as a web executable.

Before you install

The name and description point at trading, but no tools, README or instructions are published, so what it can actually do — and whether it can place or modify orders — cannot be verified. No credentials are declared, yet trading-related servers often need wallet or API access; review the package before installing and avoid exposing funds.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
