Landing page CRO MCP for Claude

Fix your landing page without leaving Claude

Ask Claude what's stopping your ad clicks from turning into leads. Postclick reads the audit and Claude gives you the change, the exact words and a way to check it.

Claude Code calls Postclick's run_cro_skill tool for ppc.io/ai-consulting and answers: fix the headline first, with the current words, the new words, why and how to check it.

What should I fix first on ppc.io/ai-consulting?

Postclick read the audit of ppc.io/ai-consulting

Fix the headline first.

Now
"PPC, reporting, SEO and landing pages."
Change to
"Clear your entire marketing backlog for $3,000 a month"
Why
The biggest words on the page are a list of services. A marketing lead has to read the small print to find out what they get. The $3,000 price is already on the page, so the new line adds no new claim.
Check
Change only the headline, then compare enquiries against the old version.
Real output: Claude Code with the Postclick plugin on 11 Nov 2026, reading the audit I ran on my own consulting page in September.

Troubleshooting

If something goes wrong

Postclick's tools don't show up
Start a new chat. Most apps load a new connector when a chat starts.
ChatGPT answers without Postclick
Start your message with @Postclick.
No option to add a custom connector
Custom connectors depend on your Claude or ChatGPT plan. Check the plan in your account settings.
"Sign in again" or a sign-in error
Connect Postclick again. In Claude Code, type /mcp and pick postclick. In the apps, disconnect it and connect again.
Postclick can't find your page
Give the full page address, like https://example.com/landing-page.
The audit didn't start
It needs your yes. Postclick checks your plan and asks before any paid work, so reply yes to go ahead.
The audit is still running
Ask "how is my audit going?" The audit runs on Postclick, so you can leave the chat and come back.

FAQ

Questions about Postclick in Claude

What's the difference between the plugin and the connector?

The connector adds Postclick's 21 tools to the Claude app on the web and on desktop. The Claude Code plugin adds the same tools plus 5 skills, like postclick-fix-first, that Claude can run by name. The skills also work on page copy you paste in, with no Postclick account.

What is the Postclick MCP server?

It's a hosted MCP server that gives Claude 21 landing page tools. You can read your Postclick audits, rewrite your page copy, check your ad against the page, see competitor ads and build a new page, all from the chat.

What is the server URL?

https://mcp.ppc.io. It's a remote server over Streamable HTTP with OAuth sign-in, so there's nothing to install.

Do I need an API key?

No. You sign in to Postclick in your browser the first time Claude connects. Claude gets a token and never sees your password.

Which AI tools does it work in?

Claude on the web, on desktop and in Claude Code, plus ChatGPT, Cursor, Grok, Windsurf, VS Code, Cline and Codex. Any app that can add a remote MCP server with OAuth can use it.

What does it cost?

Your first audit is free and needs no card. Starter is $70 a month for 10 audits and 2 new landing pages. Pro is $200 a month for 20 audits and 6 new pages.

Will it spend money without asking?

No. Only 3 tools use your plan: a new audit, page designs and a page build. Before any of them, Claude checks what your plan covers, tells you and waits for your yes. If you asked for that audit or build in your message, that counts as your yes. Reading audits you already have is free.

Can Postclick change my live site?

No. You get the words to change, a brief for your designer, or a new page as one HTML file you own. In Cursor or Claude Code you can then ask the editor to make the change in your files, and you approve it there.

What's in an audit?

What to fix on the page, ranked, the doubts your buyers have, how well your ad matches the page, and the competitors bidding on the same searches.

Are my audits and pages private?

Yes. A draft stays private until you ask for a share link or publish it.

What does the free plan include?

One full audit of one page. Run it within 30 days of signing up.
