Frequently asked questions

What is mttr?

Reads a site as search engines and AI assistants do, ranks its fixes, and checks them live.

How do I install mttr?

It runs as a remote server. In Claude Code: claude mcp add --transport http mttr 'https://mttr.si/mcp' --header 'Authorization: <Bearer and a free mttr key (mk_...) from https://mttr.si/agents. Without one, an agent can sign up with mttr_signup.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does mttr need an API key?

Yes. It expects Authorization, which you set in its configuration.

Who maintains mttr?

It is published by si.mttr. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
