Featureflip

@featureflip/mcp

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

Setup

1. 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.
2. Add the server to your MCP client:

Claude Code

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

Cursor / Cline / generic JSON config

{  "mcpServers": {    "featureflip": {      "command": "npx",      "args": ["-y", "@featureflip/mcp@latest"],      "env": { "FEATUREFLIP_TOKEN": "ffp_your_token" }    }  }}

Keep the @latest. Without a version, npx reuses the copy it downloaded the first time and never checks npm again, so tools added in later releases would never show up in your client.

Configuration

Tools

CRUD: list_projects, list_environments, list_flags, get_flag, create_flag, update_flag, delete_flag, archive_flag, restore_flag, set_flag_expiry, set_flag_owner, set_flag_permanent, toggle_flag, update_flag_environment_config, copy_flag_config, get_targeting, update_targeting, manage_targeting_rule, manage_variation, list_segments, get_segment, manage_segment, manage_project, set_default_flag_lifetime, manage_environment, list_sdk_keys, manage_sdk_key, list_flag_triggers, manage_flag_trigger

Webhooks (Admin token required): list_webhooks, list_webhook_deliveries, manage_webhook, deliver_webhook

Workflows: flag_status (cross-environment view), flag_evaluations (what a flag served in one environment: evaluation counts by variation and rule), compare_environments (which flags differ between two environments), find_stale_flags (cleanup candidates), list_removal_candidates (flags safe to remove, with the prerequisite dependents to remove first), wrap_feature (create flag + get the SDK snippet for your language)

Notes

• Flag evaluation is not exposed over MCP — use the language SDKs in application code.
• Every mutation is audit-logged and attributed to the token.
