Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "featureflip": {
      "command": "npx",
      "args": [
        "-y",
        "@featureflip/mcp"
      ],
      "env": {
        "FEATUREFLIP_TOKEN": "your-value",
        "FEATUREFLIP_API_URL": "your-value",
        "FEATUREFLIP_ORG": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add featureflip --env FEATUREFLIP_TOKEN=your-value --env FEATUREFLIP_API_URL=your-value --env FEATUREFLIP_ORG=your-value -- npx -y @featureflip/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "featureflip": {
      "command": "npx",
      "args": [
        "-y",
        "@featureflip/mcp"
      ],
      "env": {
        "FEATUREFLIP_TOKEN": "your-value",
        "FEATUREFLIP_API_URL": "your-value",
        "FEATUREFLIP_ORG": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "featureflip": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@featureflip/mcp"
      ],
      "env": {
        "FEATUREFLIP_TOKEN": "your-value",
        "FEATUREFLIP_API_URL": "your-value",
        "FEATUREFLIP_ORG": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

FEATUREFLIP_TOKEN secret required env
Featureflip API token. A personal token (ffp_) acts as you; a service token (ffs_) is a scoped machine identity for CI and agents.
FEATUREFLIP_API_URL env
Management API base URL. Defaults to https://api.featureflip.io.
FEATUREFLIP_ORG env
Organization slug. Only needed for a personal token that can reach more than one organization.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Featureflip safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: FEATUREFLIP_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.8.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@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, 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

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), 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)

Full reference: https://featureflip.io/docs/integrations/mcp/

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.
