ConfigCat MCP Server

The ConfigCat's Model Context Protocol (MCP) server provides access to ConfigCat's public management API for feature flag and configuration management. It also enables your code editor to understand your feature flags, integrate the appropriate ConfigCat SDK into your project or even create new feature flags directly in your codebase.

Features

  • Tools:
  • Complete set of tools for ConfigCat's public management API operations. You can Create, Read, Update and Delete any entities like Feature Flags, Configs, Environments or Products within ConfigCat.
  • Get comprehensive SDK documentation and code examples for seamless feature flag implementation in your project.

Setup

You can use the following environment variables to configure the MCP server.

The instructions below show how to connect a client to the MCP server.

Cursor

  1. Open Preferences -> Cursor Settings -> MCP & Integrations
  2. Click Add Custom MCP
  3. Add the following server definition for the ConfigCat MCP server:
{
  "mcpServers": {
    "ConfigCat": {
      "command": "npx",
      "args": ["-y", "@configcat/mcp-server"],
      "env": {
        "CONFIGCAT_API_USER": "YOUR_API_USER",
        "CONFIGCAT_API_PASS": "YOUR_API_PASSWORD"
      }
    }
  }
}
  1. Save the settings.

Visual Studio Code

  1. Create a .vscode/mcp.json file in your project root with the following content:
{
  "servers": {
    "ConfigCat": {
      "command": "npx",
      "args": ["-y", "@configcat/mcp-server"],
      "env": {
        "CONFIGCAT_API_USER": "YOUR_API_USER",
        "CONFIGCAT_API_PASS": "YOUR_API_PASSWORD"
      }
    }
  }
}
  1. Save the settings file. The MCP server should now be available in VS Code.

Claude Desktop

  1. Open Settings &rarr; Developer
  2. Click Edit Config
  3. Open claudedesktopconfig.json
  4. Add the following server definition for the ConfigCat MCP server:
{
  "mcpServers": {
    "ConfigCat": {
      "command": "npx",
      "args": ["-y", "@configcat/mcp-server"],
      "env": {
        "CONFIGCAT_API_USER": "YOUR_API_USER",
        "CONFIGCAT_API_PASS": "YOUR_API_PASSWORD"
      }
    }
  }
}
  1. Save and restart Claude.
