# Cleric Cleric is a desktop application that helps you manage Model Context Protocol (MCP) servers for [Claude desktop](https://claude.ai/download). It provides an easy-to-use interface for adding, removing, and configuring your MCP servers. Builds are available for MacOS and Windows at: https://github.com/pcarion/cleric/releases > **Note:** The version `0.3.0` is available for Windows but has not been tested on Windows. Any feedback is welcome. The code related to starting and stopping the MCP Inspector should be looked at. ## How It Works Cleric manages two configuration files: 1. A personal server list at `$HOME/.cleric.json` - Stores all your available MCP servers - Acts as a backup of your server configurations 2. The Claude Desktop configuration at `/claude_desktop_config.json` - Contains the active MCP servers currently used by Claude Desktop ## Key Features - Seamlessly switch MCP servers in and out of Claude Desktop - Automatically preserves server configurations when making changes - Syncs with Claude Desktop: Any servers you manually add to Claude Desktop will be automatically added to your Cleric server list on next launch - Real-time saving: Changes are saved automatically as you make them - Test any server by launching the MCP Inspector ## How to use On the left side of the application, you can see the list of MCP servers that you have configured. The servers with a checkmark are the ones that are currently configured in Claude desktop. The right side of the application shows the information about the selected server: ![MCP server information](assets/cleric-screenshot-01.png) The `Remove From Claude` button will remove the server from Claude desktop but the server will remain in your personal server list. The `✄` button will remove the server from both your personal server list and the list of servers that are currently configured in Claude desktop. The `🖊️` button will allow you to edit the server information: ![MCP server information](assets/cleric-screenshot-02.png) The `👁️` button will show you the command to start the MCP Inspector in the terminal: ![MCP server information](assets/cleric-screenshot-03.png) ## Important Note Before using Cleric for the first time, please back up your `claude_desktop_config.json` file if you have manually configured MCP servers in Claude Desktop. Don't forget to restart Claude Desktop after you have made changes to the server list. ### MacOS issue when launching the app If you get the "cannot be opened because the developer cannot be verified" error, you can apply the following workaround. * Control-click the app icon, then choose Open from the shortcut menu. * Click Open. If you get the "cleric is damaged and can't be opened. You should move it to the Bin." error you can apply the following workaround. Launch Terminal and then issue the following command: `xattr -cr /path/to/cleric.app`. ## Changelog - `0.5.0` - 2025-01-25 - remove capabilities to start the MCP Inspector.
