Fingerprint skills - Fingerprint Docs

Fingerprint skills are installable packages that give AI coding agents specialized knowledge about Fingerprint. Once installed, your agent can help you add Fingerprint to your stack, act on Smart Signals, serve the JavaScript agent from your own domain, configure the Rules Engine, and more. For example, ask your agent to add Fingerprint to your app, and it detects your framework, installs the right SDK, adds visitor identification on the frontend, and adds server-side verification on the backend. Skills follow the Agent Skills standard and work with Claude Code, Cursor, Codex, OpenCode, Pi, and other compatible agents. The source is available in the fingerprintjs/skills GitHub repository.

Why use skills

Matched to your stack: your agent applies the integration guide for the framework your project uses.
Secure by default: every integration pairs frontend identification with server-side verification and keeps your secret API key out of client code.
Current APIs: each skill points your agent to Fingerprint’s live documentation, so it confirms package names, options, and response fields against the current version.

Prerequisites

A Fingerprint account to get your API keys
A coding agent that supports Agent Skills

Fingerprint skills set up JavaScript agent v4 and Server API v4. If your app already uses JavaScript agent v3, your agent keeps your existing integration and doesn’t migrate it. To upgrade, follow Migrating JavaScript agent from v3 to v4.

Install

npx skills
Claude Code
Cursor
Manual

Use the skills CLI to install Fingerprint skills for any supported agent:

npx skills add fingerprintjs/skills

Fingerprint skills are available as a Claude Code plugin. The plugin also connects the Fingerprint MCP server.In the Claude Code CLI, add the marketplace and install the plugin:

/plugin marketplace add fingerprintjs/skills
/plugin install fingerprint@fingerprint

Run /reload-plugins to activate the plugin.In the Claude desktop app, open Customize > Plugins, add the marketplace source fingerprintjs/skills, select the fingerprint plugin, and click Install. Restart the app to activate the plugin.After installing, start the guided setup in any project:

/fingerprint:get-started

Go to Settings > Plugins and click Browse Marketplace to find Fingerprint. You can also paste https://github.com/fingerprintjs/skills into the Pasted Link field. Select the fingerprint plugin to install it.Fingerprint is also listed in the Cursor directory.

Clone the fingerprintjs/skills repository and copy the folders in skills/ to your agent’s skills directory:

Agent	Skills directory
Claude Code	`~/.claude/skills/`
Cursor	`~/.cursor/skills/`
Codex	`~/.codex/skills/`
OpenCode	`~/.config/opencode/skills/`
Pi	`~/.pi/agent/skills/`

Use skills

Open your project in your coding agent and ask in plain language:

Add Fingerprint to this app

Your agent reads your project, loads the matching skill, and makes the changes. Review and test each change before you commit it. For the full list of skills and the stacks they support, see the fingerprintjs/skills README.

Skills and the MCP server

Skills give your agent knowledge about Fingerprint. The Fingerprint MCP server gives your agent live access to your workspace, so it can search identification events and manage environments and API keys. Use both together: the Claude Code plugin includes the MCP server, and the MCP server also exposes the same skills through its list_skills tool.
