Connect ChatGPT

Updated 2026-10-18

Only a remote (hosted) server works. ChatGPT cannot start a local npx process.

Steps

In ChatGPT Settings, turn on Developer mode. The switch is usually under Apps / Connectors → Advanced, and under Security on some accounts.
On the connectors page press Create. Use Dyscalculia.io as the name, one sentence as the description (for example Dyscalculia prevalence figures and study sources) and the URL below.
Choose No authentication, tick the trust box and create the connector.
In a new chat, enable the connector from the tools menu.

Configuration

Connector URL

https://mcp.dyscalculia.io/mcp

Check it works

Ask: “Using Dyscalculia.io, what share of school-age children have dyscalculia, and what is the source?” The answer should be about 3 to 6 percent, with the study it comes from and its year.

Which plans include Developer mode, and its menu names, change on OpenAI's side. On Business and Enterprise an admin may have to allow custom connectors. None of the tools writes anything; all six are read-only.
