Model Context Protocol

An SEO MCP server that actually tracks your rankings

Give Claude, ChatGPT or Cursor direct access to your Google positions. Ask what moved, what is cannibalising what, and what to track next — answered from your own recorded rank checks, not from a live guess.

Install

Connect it in under a minute

Create an API key in LemRank: sign in, open REST API Documentation (/api-docs) and use the API Keys tab. The key is shown once and stored only as a hash.
Add the server below to your assistant and paste the key in place of YOUR_LEMRANK_API_KEY.
Ask it something like “which of my keywords dropped this week?”

Endpoint

https://lemrank.com/api/public/mcp

Claude Desktop, Cursor, Windsurf and other clients that read a JSON config

{
  "mcpServers": {
    "lemrank": {
      "url": "https://lemrank.com/api/public/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_LEMRANK_API_KEY"
      }
    }
  }
}

Claude Code

claude mcp add --transport http lemrank https://lemrank.com/api/public/mcp \
  --header "Authorization: Bearer YOUR_LEMRANK_API_KEY"

In ChatGPT, add it as a remote connector using the same endpoint and put the key in an Authorization: Bearer header. Any client that speaks Streamable HTTP MCP will work — the server holds no session state. The same data is available over REST.

Tools

What the assistant can do

Tool	What it returns
list_projects	Every site the API key tracks, with its domain, tracking frequency, default language and default location.
get_project	One tracked site, checked against the key's owner.
list_keywords	Current Google positions, previous and best position, ranking URL, volume, CPC and difficulty.
ranking_history	Up to 90 days of recorded positions with check dates, so the assistant can describe movement rather than guess.
serp_snapshots	Whether an AI Overview, featured snippet or local pack was present when the result page was captured.
track_keyword	Add a keyword to tracking. Returns the existing one instead of creating duplicates.
url_intel	For one URL you own: ranking keywords, 30-day sparklines, cannibalisation, toxic backlink count and AI citations.
whoami	Confirm which account the configured key belongs to.

What it does not do: it has no site crawler and no third-party backlink index of its own. For a technical crawl, pair it with a crawler MCP — we say which ones in the roundup.

Why this one

Tracking data beats live lookups

It remembers, because it tracks

Most SEO MCP servers query data live, one question at a time. LemRank stores scheduled keyword checks, so the assistant can compare recorded positions instead of guessing from a single lookup. Check dates depend on your plan and scheduling.

Up to ninety days of history per call

Recorded positions come back with their check dates. The API can read up to 90 days in one request; it does not imply that every keyword was checked daily.

Scoped to your account

Every call carries your own API key and is re-checked against the account that owns each project. A key can never read another workspace.

No install, no local process

It is a remote server over Streamable HTTP. Nothing to run on your machine, nothing to keep awake for a scheduled task.

In practice

Things to ask it

Which keywords dropped more than five places this week?
Summarise the ranking trend for my top twenty keywords over the last 30 days.
Which of my pages are competing for the same keyword?
Track these fifteen keywords for me.
Which tracked keywords show an AI Overview on the results page?

Check it works

Call it directly

List the tools with curl

curl -X POST https://lemrank.com/api/public/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer YOUR_LEMRANK_API_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Rate limits and error codes match the REST API: 60 requests a minute per key, and a clear message when a key is missing, expired or out of quota.

Start tracking, then plug it in

The MCP server reads whatever LemRank is tracking for you, so the first step is adding your keywords. The trial is free and needs no card.
