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. Its 40 documented tools cover product, permission, member, group.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
