Overview

What is ConfigCat MCP Server?

The ConfigCat MCP Server provides access to ConfigCat's public management API for feature flag and configuration management. It enables code editors to understand feature flags, integrate the appropriate ConfigCat SDK into a project, or create new feature flags directly in the codebase. It is designed for developers managing ConfigCat feature flags and configurations.

How to use ConfigCat MCP Server?

Configure the server with the required environment variables CONFIGCAT_API_USER and CONFIGCAT_API_PASS (and optionally CONFIGCAT_BASE_URL). Connect via Cursor, Visual Studio Code (.vscode/mcp.json), or Claude Desktop by adding a JSON server definition that runs npx -y @configcat/mcp-server with the environment variables.

FAQ from ConfigCat MCP Server

What authentication is required?

The server uses basic authentication with a CONFIGCAT_API_USER and CONFIGCAT_API_PASS (public API credentials from the ConfigCat dashboard).

What are the rate limits?

The ConfigCat public API has rate limits; the server respects these and returns appropriate error messages if limits are exceeded.

Can I use this server to evaluate feature flags in production?

No. The server is for management operations only. Use the ConfigCat SDKs or ConfigCat Proxy for evaluating flag values in production applications.

How is the server connected to clients?

The server runs via npx using stdio transport. Configuration is provided as environment variables in the MCP client’s server definition.
