Query flag status via Claude Code

This MCP Server exposes your ConfigCat feature flags to your terminal environment. When debugging an issue, Claude Code can run `get_setting_value` to check the live status of a flag without forcing you to open a browser. You can pipe the terminal output from Claude Code directly into other shell scripts. The agent uses `list_settings` to dump your active ConfigCat flags and filters them using standard command-line tools.

Scripted environment management

Automating your deployment pipelines is straightforward with this terminal ConfigCat MCP Server. Claude Code calls `create_environment` during your CI/CD runs to spin up temporary test environments automatically. Claude Code tears down these ConfigCat environments when the pipeline finishes by invoking `delete_environment`. This keeps your testing setup clean and prevents configuration drift.

Direct segment configuration

This tool manages user targeting and segment rules directly from your Claude Code command line. The agent calls `create_segment` to establish new rules and links them to your active ConfigCat configurations using `update_setting_value`. Claude Code verifies the setup by running `list_segments` and printing the ConfigCat JSON payload directly to your terminal. No manual validation required.
