What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • identify_mark

    Ranks catalogue marks that match a description of a mark: visible wording or letters, symbols, outline shape, colour, how it was made, category, country and years of use. Returns pages of marks with maker, image, period and the details that matched, plus a link to the same search

  • find_makers

    Searches makers and their aliases by name across pottery, silver, jewelry, glass and other maker marks, optionally within one category or country. Returns pages of makers with place, active years, number of marks and an example mark image.

  • get_details

    Returns the full public record for one mark or one maker: wording, type, period and dating notes for a mark; history, aliases, what to look for and look-alike makers for a maker. Includes links to the matching pages on Marks & Signatures.

  • get_maker_marks

    Returns the marks of one maker with images, wording, type and period, in date order. Accepts a maker id or a mark id; with a mark id that mark comes first.

  • list_categories

    Lists the five mark categories with the number of marks and makers in each and a link to each category page.

Common questions

Is Marks & Signatures safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, AvaHR
