Polarity

Overview

Polarity is a Model Context Protocol (MCP) server: Real-time threat intelligence lookups and IOC parsing from your self-hosted Polarity instance. Because it speaks the Model Context Protocol, AI assistants can use Polarity as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @polarityio/mcp-connector speaks MCP over stdio on your machine. The current release is v1.0.1.

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