Mcp Server

Overview

Mcp Server bridges AI agents and ConfigCat, a feature flag service for teams. By implementing the Model Context Protocol, it lets AI assistants query and manage feature flags as callable tools, eliminating manual copy-pasting between applications.

The server runs locally via the npm package @configcat/mcp-server, communicating with your MCP client over stdio. You'll need to provide CONFIGCAT_API_USER and CONFIGCAT_API_PASS as environment variables to authenticate with ConfigCat. Version v0.1.3 is available now under the MIT license, with full source code at configcat/mcp-server on GitHub.

Mcp Server is listed in the AI & Agents category on mcp.site and works with any MCP-compatible client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server for ConfigCat, claim your listing to earn the Verified badge and keep information current.
