## What it does

The server connects an AI coding assistant to DevCycle for feature flag management. It can create flags, update them, and work with their values from the assistant’s development environment.

DevCycle hosts the MCP endpoint, so there is no local server package to install. The connection uses `https://mcp.devcycle.com/mcp`; on first use, the service takes the user through OAuth authentication. Flag management starts after that sign-in flow is complete.

The server can be connected to Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, and other listed clients. In Claude Code, add it with `claude mcp add` over HTTP.

## Requirements
