MCP (Model Context Protocol) server for Featureflip — manage feature flags from AI coding assistants (Claude Code, Cursor, Copilot, Cline) and autonomous agents.

Setup

Create an API token in the Featureflip dashboard:
- Personal token (ffp_...): Settings → API Tokens — acts as you, for interactive editor use.
- Service token (ffs_...): Organization Settings → Service Tokens — scoped machine identity for CI/agents.
Add the server to your MCP client:

Claude Code

claude mcp add featureflip -e FEATUREFLIP_TOKEN=ffp_your_token -- npx -y @featureflip/mcp
