Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @featureflip/mcp
Claude Code 
claude mcp add featureflip -e 'FEATUREFLIP_TOKEN=<your featureflip_token>' -e 'FEATUREFLIP_API_URL=https://api.featureflip.io' -e 'FEATUREFLIP_ORG=<FEATUREFLIP_ORG>' -- npx -y @featureflip/mcp@0.4.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "featureflip": {
            "command": "npx",
            "args": [
                "-y",
                "@featureflip/mcp@0.4.0"
            ],
            "env": {
                "FEATUREFLIP_TOKEN": "<your featureflip_token>",
                "FEATUREFLIP_API_URL": "https://api.featureflip.io",
                "FEATUREFLIP_ORG": "<FEATUREFLIP_ORG>"
            }
        }
    }
}

Environment variables

  • FEATUREFLIP_TOKEN required secret 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 Management API base URL. Defaults to https://api.featureflip.io.
  • FEATUREFLIP_ORG Organization slug. Only needed for a personal token that can reach more than one organization.

@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
Cursor / Cline / generic JSON config
{
  "mcpServers": {
    "featureflip": {
      "command": "npx",
      "args": ["-y", "@featureflip/mcp"],
      "env": { "FEATUREFLIP_TOKEN": "ffp_your_token" }
    }
  }
}

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.
