PolicyClient Claude Desktop Integration
This guide explains how to configure Claude Desktop (Mac and Windows) to use the PolicyClient API through the Model Context Protocol (MCP). The integration exposes 10 API endpointsas callable tools inside Claude's chat interface, including PolicyAssignments_List, PolicyDefinitions_List, PolicyDefinitions_Get, and more. No API keys or credentials are needed — setup takes approximately 30 seconds. The server runs locally via npx and communicates over STDIO transport. Paste the JSON configuration below into your claude_desktop_config.json file to get started.
