HarborRank

Claude SEO skills and SEO MCP server (HarborRank)

Eighteen free, MIT-licensed Claude SEO skills, plus the HarborRank SEO MCP server that gives them live keyword, SERP, backlink and Google Search Console data. They work in Claude, Claude Code, Cursor, Gemini CLI, Codex, and other agents that support SKILL.md files. Every skill works on its own from web evidence and your files, and gets live numbers when HarborRank is connected.

Contributions welcome. Found a way to improve a skill or have a new SEO workflow to add? See CONTRIBUTING.md and open a PR.

Each skill is one slash command. With HarborRank connected, the skills pull live data through the HarborRank MCP server: keyword metrics, SERPs, ranked keywords, backlinks, rank tracking, Google Search Console, and Google Analytics.

Install in Claude (web, desktop, Cowork)

1. Install HarborRank SEO from the plugin directory, or add the HarborRank connector (Customize, then Connectors).
2. Choose Connect and sign in to HarborRank with Google or email to start your 7-day free trial.
3. Back in Claude, ask for something real, for example "Find 20 low-difficulty keywords for mysite.com and save the best ones to my project" or "Which of my pages sit at positions 8 to 20 in Search Console?"

If you ask before connecting, Claude says HarborRank isn't connected, gives these steps, and picks the task back up once you say "connected".

Install as a Claude Code plugin

One install adds the HarborRank MCP server and all eighteen skills. Inside Claude Code:

/plugin marketplace add winsley-jeune/harborrank-skills

/plugin install harborrank@harborrank

Then run /mcp, pick harborrank, and sign in (setup guide). The first MCP call opens the HarborRank login in your browser. Installed this way the skills run as /harborrank: , for example /harborrank:keyword-research.

Install in Cursor

Install HarborRank SEO from the Cursor Marketplace, or add the MCP server by hand in ~/.cursor/mcp.json:

{ "mcpServers": { "harborrank": { "url": "https://app.harborrank.com/mcp" } } }

Cursor opens the HarborRank login the first time it connects. The plugin also adds the eighteen skills.

Install in ChatGPT

Add HarborRank from ChatGPT's plugin directory and sign in when ChatGPT asks. It connects the same MCP server; the skills in this repository are for agents that read SKILL.md files.

Install as a Gemini CLI extension

gemini extensions install https://github.com/winsley-jeune/harborrank-skills

Then run /mcp auth harborrank in Gemini CLI to sign in. The extension adds the MCP server and the eighteen skills.

Requirements

• A HarborRank account. Start free: new accounts get a 7-day free trial with 1,000 research credits, one project, Search Console, and Google Analytics. You add a card at signup; Basic ($29/month, 15,000 credits a month) starts when the trial ends unless you cancel from Billing first. Backlinks, lead research, and Lighthouse checks need a paid plan, and you can email support@harborrank.com within 7 days of the first charge for a full refund.
• Claude Code, Cursor or Gemini CLI (or another agent that reads SKILL.md files and can connect to a remote HTTP MCP server).

Example prompts

• "Research keywords for a Plymouth, MA marine electrician: shortlist ten with volume, difficulty and intent, and save the good ones to my project."
• "Who ranks for my saved keywords, and where are the openings a small site could take?"
• "Which of my pages bring in leads from Google, and how much of my traffic now comes from ChatGPT and other AI assistants?"
• "Is /pricing indexed? If not, why not, and which of my pages are sitting at positions 8 to 20?"

What the plugin runs, sends and fetches

• The skills are plain-text instructions. They run nothing on your machine and install no code.
• .mcp.json (Claude Code), mcp.json (Cursor) and gemini-extension.json (Gemini CLI) all point at one remote MCP server, https://app.harborrank.com/mcp, over HTTPS with OAuth 2.0. No credentials are stored in this repository.
• Tool calls send the arguments you or the agent supply (keywords, domains, URLs, a project id) to HarborRank, which fetches SEO data from DataForSEO and, when you connect a property, read-only data from your Google Search Console and Google Analytics. Nothing is sent anywhere else.
• Research and Google Analytics tools use plan credits; Search Console and saved-keyword reads use none.
• Privacy policy: https://harborrank.com/privacy?utm_source=github&utm_medium=readme&utm_campaign=harborrank-skills Terms: https://harborrank.com/terms-and-conditions?utm_source=github&utm_medium=readme&utm_campaign=harborrank-skills Support: support@harborrank.com.

Install the skill files only

For Codex or any agent that reads SKILL.md files, or if you already added the MCP server by hand:

npx skills add winsley-jeune/harborrank-skills

Install everything for Claude Code only:

npx skills add winsley-jeune/harborrank-skills --skill '*' --agent claude-code

Or copy the folders under skills/ into ~/.claude/skills/ (Claude Code) or ~/.codex/skills/ (Codex).

If you install the files only, connect HarborRank MCP first. The skill files are instructions, not data: without the MCP connection your agent only has what it can see on its own.
