Coteach
Math diagram generation for K-12 teachers inside Claude
Overview
What Coteach does
Coteach is built for K-12 mathematics instruction. A teacher describes the visual in ordinary words and the connector returns up to four separate diagrams: number lines, tape diagrams, arrays, area models, coordinate planes, fraction models. The intended uses named in the listing are lesson planning, worksheets, practice problems, and visual scaffolds for students who need them. One published tool fits a connector that does a single thing rather than wrapping a product's whole API. Coteach carries partner tier, meaning the listing passed a review step rather than being self-published, and it publishes both an endpoint URL and documentation.
Tool surface
A single tool is listed, and the endpoint returns 401 before naming it, so its arguments and output format stay the publisher's claim rather than something checkable.
Availability
Where Coteach is listed
Coteach is listed in the Claude connectors directory only. Coteach has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
Coteach publishes 1 tool to Claude, a deliberately narrow surface; only 0.7% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Education & Research publishes 4, so this one sits 3 tools below its bucket's median, 13th of 14.
It falls in the 1-3 tools band, which holds 16.4% of the Claude directory.
Coteach publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Coteach carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.
In the publisher's words
How Coteach describes it
Coteach helps K-12 math educators create classroom-ready diagrams directly in Claude. Describe the visual you need in plain language, and Coteach generates up to four separate math diagrams. It is useful for lesson planning, worksheets, practice problems, and visual scaffolds such as number lines, tape diagrams, arrays, area models, coordinate planes, and fraction models.

This is an independent catalogue entry compiled by Node8 from Coteach's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Coteach, and inclusion here is not an endorsement.
