Use cases

Six jobs to hand your assistant on day one.

Every prompt here works as written in any connected client. Copy one into your chat and approve each change as it comes.

  • How did my landing pages do last week? Visits, leads and conversion rate for each, best first, and flag any page whose conversion rate fell from the week before.

    • reporting_get

    14 landing pages, 48,210 visits, 1,932 leads. solar-az-v2 leads at 6.1%. roofing-tx fell from 4.8% to 3.2%, the only real drop.

    Monday landing page report

    Last week's numbers for every page, best first, with the drops flagged.

  • Which of my A/B tests has a clear leader? Pause the weakest variant and send 70% of the traffic to the leader.

    • variants_list
    • analytics_stats
    • variants_disableApproved
    • variants_set_weightsApproved

    solar-az: B converts at 4.2%, A at 3.1%, C at 1.8%. C is paused, and B now gets 70% of the traffic.

    Pick the split test winners

    Find the leader in each A/B test, pause the weakest variant and move the traffic.

  • Write last month's report for each client workspace: visits, leads and conversion rate by page against the month before, and the page that did best.

    • workspaces_list
    • reporting_get

    Roofing TX, September: 412 leads from 11,380 visits, up 14% on August. storm-damage-quiz did best, at 5.2%.

    Client reports

    Each client's month, page by page, written up and ready to send.

  • Publish my newest landing page, switch on the HubSpot integration for it and tell me the URL it's live on.

    • landers_list
    • lander_publishApproved
    • integrations_list
    • lander_integration_enableApproved

    roofing-houston is live at roofing.yourdomain.com/houston, with HubSpot on, so each lead lands as a contact.

    Launch a landing page

    Published, wired to your CRM and checked, from one message.

  • Pull this week's leads from every page and find duplicates and test entries. Delete the test entries once I confirm.

    • leads_list_org
    • leads_delete_orgApproved

    1,142 leads so far this week. 38 repeat an earlier lead's email, and the 5 test entries are deleted.

    Lead cleanup

    Duplicates and test entries caught before a buyer sees them.

  • List my published landing pages that aren't in ClickFlare yet and add them there with the same names.

    • landers_list
    • ClickFlare's MCP server

    3 published landing pages weren't in ClickFlare: solar-az-v2, roofing-tx and medicare-fl. All three are added, same names and URLs.

    Add landing pages to ClickFlare

    With ClickFlare's MCP server connected too, new landing pages go into your tracker by name.

Setup

Three steps, no API key.

Add LanderLab to your assistant, approve the access once, and ask for your landing pages.

  1. 01

    Add LanderLab to your assistant

    In Claude, find LanderLab under Settings, Connectors, Browse connectors. Anywhere else, add the server URL https://api.landerlab.dev/mcp.

  2. 02

    Sign in and approve

    A LanderLab sign-in page opens in your browser. Approve the access request once. There is no key to paste and nothing sensitive in a config file.

  3. 03

    Ask

    Start a new chat and ask for your landing pages. Choose which tools run on their own and which wait for your approval.

Clients

Works with the assistant you already use.

One server URL for every client. Each one has a setup guide in the docs.

  • Claude

    A listed connector on the web and in the desktop app. Search for LanderLab, click Connect, sign in.

  • Claude Code

    claude mcp add --transport http landerlab https://api.landerlab.dev/mcp, then /mcp to sign in.

  • ChatGPT

    Settings, Apps, Create app, with the server URL and OAuth. ChatGPT adds custom apps on the web, not in its desktop app.

  • Cursor

    Add the server to .cursor/mcp.json, or ~/.cursor/mcp.json for every project, then click Login.

  • Windsurf

    Add it under Windsurf Settings, MCP, and sign in from the browser window that opens.

  • Gemini CLI, Manus and more

    Any client that supports remote MCP servers connects to the same URL with OAuth.

Before and after

Ask in the chat instead of clicking through the dashboard.

Ask Claude or ChatGPT for numbers, splits and leads in plain English. The MCP server does the clicking.

The old way

  • “Workspace, page, date range. Then read the table.”
  • “Open the test, drag the sliders, save.”
  • “Filter the leads tab, page by page.”
  • “Copy each landing page URL into the tracker by hand.”

The MCP way

  • “How did the solar landing pages do last week?”
  • “Send 70% of the traffic to variant B.”
  • “Show me this week's insurance quiz leads.”
  • “Add my three published landing pages to ClickFlare.”

FAQ

Questions about MCP Server.

Anything not here is in the Help Center, or ask us.

Before you start

Which plans include MCP access?

Grow, Scale and Enterprise, together with REST API access. Grow is $149 a month, or $119 a month billed yearly. You can build and publish pages on the Free plan first and upgrade when you want to connect an assistant.

Do I need an API key?

No. The MCP server signs you in with your LanderLab account over OAuth, the same login as the dashboard. API keys are only for direct REST API calls.

Is it safe to connect my account?

Yes. Your password never reaches the assistant. You approve access on LanderLab's own sign-in page, you choose which tools may run without asking, and you can revoke access any time from Settings in LanderLab or by removing the connector in your AI tool. In Claude, keep write tools on Needs approval to review every change first.

Which AI assistants work with it?

Claude on the web, in the desktop app and in Claude Code, ChatGPT on the web, Codex, Cursor, Windsurf, Manus, Gemini CLI, and any client that supports remote MCP servers. They all use https://api.landerlab.dev/mcp. Grok and Perplexity can't connect their chats to an outside MCP server yet.

Does it work in the ChatGPT desktop app?

Not in the desktop app, because ChatGPT only adds custom MCP apps on the web. Set it up in ChatGPT in your browser. Claude takes LanderLab on the web and in its desktop app.

I set it up with an API key before. What do I change?

Remove the old entry that points at /api/v2/mcp with an X-API-Key header, and add https://api.landerlab.dev/mcp instead. You sign in once and the tools load in your next chat. If it still says it needs authentication, reconnect from the same screen, or in Claude Code run /mcp and choose Authenticate.
