mttr for VS Code

Let Copilot fix your SEO

Add mttr to VS Code and ask Copilot in chat. It reads what to fix, edits your site, and has mttr check every change.

VS Code chatA sample

What should I fix first on example.com?

Used mttr_brief

Start with answering in the first lines: 14 pages open on a welcome instead of the answer. It is worth about 6 points. Want me to fix all 14?

Yes, then check it.

Used mttr_rescan

Done. Score 72 to 86, and the rule passes on all 14 pages.

Or connect with no key, and your agent signs you up itself with mttr_signup.

Connect VS Code

Add this in the site’s repository. VS Code asks for the key the first time and keeps it safe.

.vscode/mcp.json

{
  "servers": {
    "mttr": {
      "type": "http",
      "url": "https://mttr.si/mcp",
      "headers": { "Authorization": "Bearer ${input:mttr-key}" }
    }
  },
  "inputs": [
    { "id": "mttr-key", "type": "promptString", "description": "Your mttr key", "password": true }
  ]
}

Nothing to set by hand: paste the key when VS Code asks for it.

Ask VS Code something
In words. It picks the call, and the answer is the one a person sees on the report.

- Fix the top issue, then have mttr read the site again.mttr_rescan({ site: "example.com" })

A real site, fixed by its agent

A real site, shown by its code: who owns it is theirs to tell. A score says pages are well formed, not that an assistant cites the site.

Read, fix, check, until the list is empty

Readmttr_briefmttr reads the site and hands over the fixes worth the most, each with its pages.
FixCopilotThe agent makes each change in your repository, the way it would any task.
Checkmttr_rescanmttr reads the site again and says what each change fixed, and anything it broke.

Using another agent?

VS Code is its maker’s product. mttr is independent and not affiliated with it. A score says pages are well formed. It does not say an assistant cites the site.
