Use Cohort inside Claude or ChatGPT

Cohort’s college data is available as a free connector. Add it once, then ask questions in plain English. No account, no key.

Things to ask

• “Compare UCLA and UC Berkeley for computer science.”
• “What are Amador Valley’s UC admit numbers?”
• “California publics under $15k tuition that admit more than half.”

Claude

1. On claude.ai or in the Claude desktop app, open Settings → Connectors.
2. Choose Add custom connector, name it Cohort, and paste the address above.
3. Start a chat and ask. Claude shows when it uses Cohort.

In Claude Code: claude mcp add --transport http cohort https://api.collegecohort.com/mcp

ChatGPT

1. Open Settings → Connectors and turn on developer mode if it is off.
2. Choose Create, paste the address above, and leave authentication off.
3. Pick Cohort from the tools menu in a new chat, then ask.

Cohort is being submitted to the Claude and ChatGPT connector directories. Once listed, it will be one click there and the address above stays as the fallback.

Build on it

The same data is a plain web API. The description is at api.collegecohort.com/openapi.json, and /v1/methodology explains every source, unit and known gap. Rates are fractions from 0 to 1; money is US dollars per year.

Privacy

Cohort records which tools were called and how long they took, never who asked. Your questions stay between you and Claude or ChatGPT.
