Connector for Claude

Tesseract Decks & Designs

Claude writes the content; Tesseract lays it out as a page you can share: a slide deck, a diagram, a chart or a design. Each page is private in your Tesseract account until you share it.

What it makes

Four kinds of page.

Decks

16:9 slides in eight layouts (title, section, bullets, two columns, quote, big number, table and drawing) and three themes, with speaker notes. Present with the arrow keys, show the notes with N, and print to PDF.

Diagrams

Flowcharts, sequences, timelines and more from Mermaid, or a drawing Claude makes in SVG.

Charts

Bar, horizontal bar, line, area, pie, doughnut, scatter or radar, with the numbers in a table under the chart.

Designs

Mockups, logos and posters from Claude’s own HTML and CSS, or one SVG.

Tools

The six tools.

make_deck: Makes a slide deck from the slides Claude writes.
make_diagram: Makes a diagram from Mermaid, or from an SVG Claude draws.
make_chart: Makes a chart from numbers, with the numbers in a table under it.
make_design: Makes a page from Claude’s own HTML and CSS, or one SVG.
list_canvases: Lists the pages made through this connector, the most recently changed first.
get_canvas: Reads back one page made through this connector, with what it was made from.

Set it up

Add it to Claude.

You sign in with your Tesseract account and approve Claude, and that is it.

In Claude, open Settings → Connectors and choose Add custom connector.
Name it Tesseract Decks & Designs and paste the address. Leave Advanced settings empty.
Press Add, then Connect. Sign in to Tesseract, check that the page names Claude, and press Approve.
In a chat, turn it on under the tools button, then ask for a deck, a diagram, a chart or a design.

On a Team or Enterprise plan, an owner adds it once in Organization settings → Connectors, and each member presses Connect.

Any app that connects to MCP servers over Streamable HTTP with an OAuth sign-in can use it the same way: give it the address.

Questions

Good to know.

What does it cost?

Nothing, on every plan, because no AI model is called: Claude writes the content and Tesseract only lays it out. You need a Tesseract account, and a free one works. One person can make or change up to 120 pages an hour.

Who can see my pages?

Only you. Each page is private in your Tesseract account until you share it from Tesseract. A connected app can list and read only the pages made through this connector, never your other pages, conversations or files.

Can Claude change a page it made?

Yes. Asked to change a page, Claude makes a new version of it. The page keeps its earlier versions, the last 100.

Does it make pictures, video or sound?

No. It lays out what Claude writes: text, numbers, Mermaid, SVG, HTML and CSS. Nothing else is made, and no picture is fetched from the internet.

How do I disconnect it?

In Tesseract, open Settings → Account → API keys → Connected apps and remove it. It stops working on its very next request.
