Download here. MCP Server: Setting up Claude Code communication CapFrameX ships an in-process Model Context Protocol server hosted by CapFrameX.exe. Once registered with Claude Code, the assistant can read captures, compute statistics, query the live system, and diagnose capture issues. The endpoint exists only while CapFrameX is running. Setup 1. Find the port. Open %appdata%/CapFrameX/Configuration/AppSettings.json and read WebservicePort (default 1337; CapFrameX falls back to a free port if it's taken). 2. Register with Claude Code (one-time, user-scoped): claude mcp add -s user capframex --transport http http://localhost...
