Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "configcat": {
      "command": "npx",
      "args": [
        "-y",
        "@configcat/mcp-server"
      ],
      "env": {
        "CONFIGCAT_API_USER": "your-value",
        "CONFIGCAT_API_PASS": "your-value",
        "CONFIGCAT_BASE_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add configcat --env CONFIGCAT_API_USER=your-value --env CONFIGCAT_API_PASS=your-value --env CONFIGCAT_BASE_URL=your-value -- npx -y @configcat/mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "configcat": {
      "command": "npx",
      "args": [
        "-y",
        "@configcat/mcp-server"
      ],

        "CONFIGCAT_API_PASS": "your-value",
        "CONFIGCAT_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "configcat": {
      "type": "stdio",

      "args": [
        "-y",

Common questions

Is Configcat MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CONFIGCAT_API_USER, CONFIGCAT_API_PASS

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 13 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

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.

Environment variable	Required	Default	Description
CONFIGCAT_API_USER	☑		ConfigCat Management API basic authentication username.
CONFIGCAT_API_PASS	☑		ConfigCat Management API basic authentication password.
CONFIGCAT_BASE_URL		https://api.configcat.com	ConfigCat Management API host.

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

Cursor

Open Preferences -> Cursor Settings -> MCP & Integrations
Click Add Custom MCP
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" } } } }

Save the settings.

Visual Studio Code

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" } } } }

Save the settings file. The MCP server should now be available in VS Code.

Claude Desktop

Open Settings → Developer
Click Edit Config
Open claude_desktop_config.json
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" } } } }

API Rate Limits

The ConfigCat public API has rate limits. The server will respect these limits and return appropriate error messages if limits are exceeded.

Security Note

This server is designed for management operations only. Do not use it for evaluating feature flag values in production applications - use the ConfigCat SDKs or ConfigCat Proxy instead.
