Environment variable: FEATUREFLIP_TOKEN

Management API base URL. Defaults to https://api.featureflip.io.Optional

Environment variable: FEATUREFLIP_API_URL

Organization slug. Only needed for a personal token that can reach more than one organization.Optional

Environment variable: FEATUREFLIP_ORG

How to Install

Add this to your MCP configuration file:

{
  "mcpServers": {
    "io-github-canopy-labs-featureflip": {
      "env": {
        "FEATUREFLIP_ORG": "your-featureflip-org-here",
        "FEATUREFLIP_TOKEN": "your-featureflip-token-here",
        "FEATUREFLIP_API_URL": "your-featureflip-api-url-here"
      },
      "args": [
        "-y",

From the project's GitHub README.

@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

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@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

Env var	Required	Default	Purpose
`FEATUREFLIP_TOKEN`	yes	—	`ffp_`/`ffs_` API token
`FEATUREFLIP_API_URL`	no	`https://api.featureflip.io`	API base URL
`FEATUREFLIP_ORG`	no	auto	Org slug (needed only for multi-org personal tokens)

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.
