mttr
Audits websites for search engine and AI readability, ranks fixes by impact, and checks improvements live.
mttr reads websites as search engines and AI assistants do, identifies technical issues ranked by priority, and verifies fixes. Tools check structured data, SSL certificates, X cards, multi-location SEO, and track changes across rescans. Requires signup and API key.
Try asking Muse: "Show me the top fixes needed on my website to improve how Google and AI assistants read it."

How to add it to Muse
Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Also use it in ChatGPT or Claude
mttr is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
Add it to Claude
- 1
Open Claude settings
In Claude, open Settings, then Connectors.
- 2
Add a custom connector
Choose Add custom connector, give it a name, and paste the link.
- 3
Connect and use it
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Put either one up, then call mttr_claim_check. A claimed site joins their account: its Search Console figures, visits, citations and rivals, their work board and their progress page. Anmttr_claim_checkChecks the record or file from mttr_claim and, once it is found, adds the site to the person's account. A new DNS record can take a few minutes to be seen.mttr_listNames a site the person has claimed on the public leaderboard, with a link to its report, or with show false takes its name off again so it goes by an anonymous code. Only a claimed site can be named.mttr_log_workTells mttr what you did on a site, after each step: what you planned, changed, checked, or where you got stuck, what you found along the way, the files you touched and the rules you worked on. It shows on your person’s progress page, and mttr reads these to get better. Never sendmttr_approvals_setSets how you work on one of the person's claimed sites: automatic, where you deploy each change as you go, or approve, where you propose each change with mttr_propose and deploy it only once the person approves. Turning approve off is emailed to the person. mttr_proposals({ site mttr_proposeBefore you deploy a change to a site set to approve, proposes it to the person: mttr keeps it and emails them what the change is, the rule and pages, your summary marked as your words, and an Approve and a Decline link, each working once and lapsing after 72 hours. Then wait: calmttr_proposalWhere one proposal stands: pending, approved, declined or expired, with "deploy" true only once the person approved it, and their reason when they declined. Poll it every few minutes after mttr_propose; deploy only when it says approved.mttr_proposalsThe person's proposals, newest first, each with where it stands, for one site or all of them.

A fix countsmttr_content_brainA claimed site's content brain as files to save under .mttr/brain/ in its repository: what the business does and where, how its pages read, the facts its structured data states, what is worth writing, and every brief so far. Read it before writing any page.mttr_content_nextThe brief for the page most worth writing next on a claimed site: the question, why, the kind of page and its path, the facts to use, the voice, and the rules it will be held to. mttr does not write the page; you or your person do. At most three briefs are open at once. When the mttr_content_doneSays where a content brief's page went on the site, by the brief's id from mttr_content_next and the page's path. The brief goes live when a later read finds that page, and keeps where the site stood then. Ask for a read with mttr_rescan after.mttr_content_dropDrops one of your open content briefs for a site, by its id, freeing its place among the three open at once. A dropped brief is never handed out again.mttr_content_postsBriefs for posts about a page that went live from one of your content briefs: for X and for LinkedIn, the point of the page, one fact of the site's own that carries it, the link, the voice, and the characters left (X counts a link as 23). mttr writes no post and posts nothing; yomttr_queueWhat the person queued for you from their mttr, oldest first: each task with its id, its site, and the words to work from. Check it when you start, and whenever an answer says tasks are waiting.mttr_queue_doneSays a queued task is done, by its id from mttr_queue. The fix itself counts only once a later read finds it passing, so ask for a fresh read with mttr_rescan.mttr_progress_linkA private link to the person's progress page: their sites, every read, what each changed, and what this agent has asked. Signed with this key; it lapses after the days asked (30 if none, 90 at most) or when the key is rotated. Hand it only to the person.mttr_portfolioThe person's portfolio, private to them: one score across every site they have claimed, half for what was improved while they held each site, three tenths for where the sites stand now, and a fifth for search traffic, not counted yet. Every site by its real name with what it givemttr_portfolio_setChanges the person's portfolio: publish or hide it, a display name (shown as chosen by its holder, not checked; null clears it), a home site that says who is behind it (one of their sites proved by DNS or a file), or whether one site is named on it or goes by its code. A site is mttr_portfolio_vetoFor the owner of a site: takes it out of every portfolio but their own, at once, or with out false puts it back. Needs the site proved with this key by DNS or a file. To keep a site in portfolios but take its name off, call mttr_list with show false.mttr_jobHow a rescan stands: waiting, running, done or failed, and how many reads are ahead of it.mttr_eventsThe newest things that happened: reads asked for, finished and failed, scores that moved, rules that were fixed.mttr_crawlsThe crawl as it stands: the sites being read now, the next in line, and how the reads that ended over the last 1, 7 or 30 days ended.Link
