Graph Polymarket Mcp

Overview

Graph Polymarket Mcp is a Model Context Protocol server that lets you query Polymarket prediction markets via The Graph. It exposes 20 tools across 8 subgraphs, so AI assistants can call market data directly instead of switching between apps.

It runs locally via the npm package graph-polymarket-mcp, which communicates over stdio. You'll need to set the GRAPH_API_KEY environment variable to authenticate. The latest release is v1.4.0, published under the MIT license with source code at PaulieB14/graph-polymarket-mcp on GitHub.

Graph Polymarket Mcp belongs in the Development category on mcp.site. It works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep information up to date.
