What you can do with Wincher in Claude and ChatGPT

For SEO specialists and marketers who track keyword rankings with Wincher.

Find which keywords rank in the top 10

The AI lists the keywords tracked for a website with their latest position, best position, volume and difficulty, and picks out the ones near the top.

See how rankings changed over time

The AI reads the position history of one keyword, or of up to 50 keywords at once, so you can see which ones moved up or down.

Look at the search results page for a keyword

The AI reads the latest stored search result pages of a keyword, with SERP features and the ranking position, URL and domain of each result.

Compare your rankings with competitors

The AI lists tracked competitors, compares ranking summaries such as average position and share of voice, and shows your position and theirs for each keyword.

Review keyword groups or create a new one

The AI lists keyword groups with average difficulty and ranking summary, and creates a group that holds existing keywords.

Changes data

Add new keywords to track

The AI checks your keyword usage, then starts tracking up to 50 new keywords on one website. Each keyword uses a slot, and this tool cannot remove it again.

How do I connect Wincher?

Before you connect

The login page asks for your Wincher Personal Access Token.

Create it in Wincher → Account → Personal Access Tokens. The Wincher API is part of the higher paid plans. The token acts with your user's permissions and is used only to call the Wincher API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Wincher and this URL, then click Add:
    https://wincher.usefulapi.io/mcp
  3. Claude opens the login page: enter your Wincher Personal Access Token.
  4. In a chat, click + → Connectors and turn on Wincher.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

  1. Open Plugins, click +, then Add custom MCP server.
  2. Enter the name Wincher and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://wincher.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Wincher Personal Access Token.
  4. In Plugins, install Wincher, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http wincher https://wincher.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "wincher": {
      "url": "https://wincher.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "wincher": {
      "type": "http",
      "url": "https://wincher.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add wincher --url https://wincher.usefulapi.io/mcp
codex mcp login wincher

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://wincher.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Wincher Personal Access Token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Free$050 tool calls / month
Proper account$9/mo · $90/yr10,000 tool calls / month
Pro+per account$39/mo · $390/yr100,000 tool calls / month

Each paid plan covers this Wincher server only. Ask your AI to run wincher_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with wincher_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with wincher_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

  • Add keywords to trackwincher_add_keywords
    WRITE: start tracking up to 50 new keywords on ONE website. EACH keyword uses one keyword slot of the plan's keyword quota (see wincher_get_account), and it is tracked and updated from then on; this tool cannot remove keywords again. Each keyword may name a preferred_url (the landing page expected to rank). Invalid or already-tracked keywords are ignored by Wincher (not created). 'groups' are keyword group NAMES to put every keyword in (may be empty; use names from wincher_list_groups, an unknown name may create a new group).
  • Create keyword groupwincher_create_group
    WRITE: create a keyword group on a website, optionally containing existing keywords (ids from wincher_list_keywords). Uses no keyword quota.
  • Create annotationwincher_create_annotation

Your usefulapi plan · 4

  • Usage status (free-tier meter)wincher_usage_status
    Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
  • Request a missing featurewincher_request_feature
    Tell usefulapi that the user needs something the Wincher tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
  • Upgrade to Pro or Pro+wincher_upgrade
    Get a paid plan for Wincher (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionwincher_cancel_subscription
    Cancel the caller's Wincher Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run wincher_upgrade later to undo the cancel before the period ends. Does not count against the meter.

What can I do with Wincher in Claude or ChatGPT?

Find which keywords rank in the top 10. See how rankings changed over time. Look at the search results page for a keyword. Compare your rankings with competitors. Review keyword groups or create a new one. Add new keywords to track. See what you can do for the details.

Is this an official Wincher product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Wincher. The server calls the Wincher API with your own Wincher access, so it sees only the data that your account can see.

Can I connect Wincher to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Wincher Personal Access Token. See Before you connect for where to find it.

Do I put my Wincher key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Wincher Personal Access Token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Wincher credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Wincher API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Wincher.

Can the AI change my Wincher data?

Yes, if you approve it. 3 of the 22 Wincher tools can create or change data. The other 19 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Wincher server only. Cancel any time: your paid plan then runs to the end of the paid period. Run wincher_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run wincher_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run wincher_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Wincher tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with wincher_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
