Polygon

Overview

Polygon is a Model Context Protocol (MCP) server: Access stock, crypto, and ETF market data, analyst ratings, earnings, and financial news. Because it speaks the Model Context Protocol, AI assistants can use Polygon as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the Python package mcparmory-polygon (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.0.2, with source at mcparmory/registry on GitHub, where it has earned 30 stars.

On mcp.site, Polygon sits in the Finance category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
