Open Claude Settings, then choose Connectors under Customize. This page lists every connection available to Claude.
Rehearsal MCP
Your Rehearsal memory, inside ChatGPT and Claude.
You forward screenshots, record voice notes on walks, save PDFs you mean to reread. Rehearsal keeps all of it. Connect it once over MCP, and ChatGPT or Claude can search that collection mid-conversation — your own material, in the AI you already use.

Quick answer
The Rehearsal MCP server (https://mcp.tryrehearsal.ai/mcp) connects your Rehearsal account to ChatGPT and Claude over the Model Context Protocol. Paste the address into ChatGPT's Plugins page or Claude's Connectors page, sign in with OAuth, and the AI can search your saved notes, voice notes, and documents. Setup takes about three minutes.
The plumbing
What is an MCP server?
An MCP server is a small bridge that lets an AI assistant reach information that lives outside it. MCP stands for Model Context Protocol — an open standard introduced by Anthropic in 2024 and now supported by ChatGPT, Claude, and most major AI tools. Instead of you copying and pasting material into every chat, the AI asks the server for what it needs, when it needs it.
The Rehearsal MCP server is that bridge for your Rehearsal account. Ask Claude about pricing strategy and it can quietly check what you saved about pricing — the article you forwarded in March, the voice note from the drive home — and answer from your own collection. If you want the same idea for context beyond Rehearsal, we also maintain Context Hub, an open-source MCP memory server.
After you connect
Questions only your own collection can answer
Exam season
Months of collecting for one exam — screenshots, PDF chapters, current-affairs clippings, a topper's notes someone forwarded. It is all sitting in Rehearsal.
“Use Rehearsal to pull everything I saved about inflation, and show me what I keep highlighting.”
Voice notes
You think out loud — on walks, in the car, after a podcast. Every recording lands in Rehearsal, transcribed and searchable.
“Search my Rehearsal voice notes from this month. What ideas do I keep circling back to?”
Saved reading
The PDFs and articles you saved to read properly later. They stopped being a guilt pile the day they became searchable.
“Find the paper I saved about habit formation and connect it to the note I wrote last week.”
Set up
Connect in about three minutes
The server address is the same everywhere. Claude calls these custom connectors and keeps them under Settings → Connectors; ChatGPT adds MCP servers from the Plugins page in Settings.

Choose add custom connector
Select Add in the top-right corner, then choose Add custom connector from the menu.
03
Add Rehearsal

Review and create
Tick the acknowledgement after reviewing it, then select Create. ChatGPT opens Rehearsal sign-in so you can authorise your account, and the connector appears in your chats.
First question
Start a new chat and name Rehearsal directly, so the client knows which tool to reach for:
“Use Rehearsal to find what I saved about pricing strategy, then give me the three ideas I return to most.”
Private by design
Your collection stays yours
OAuth, in your browser
ChatGPT and Claude open Rehearsal's own sign-in page. You approve access to your account; no keys or passwords are shared with the AI client.
Search and read only
The connection can look things up in what you saved. It cannot edit, delete, or add anything to your Rehearsal account.
One-tap disconnect
Remove Rehearsal from ChatGPT's Plugins page or Claude's Connectors page whenever you like, and reconnect later with the same address.
Questions
Setup, answered
What is the Rehearsal MCP server URL?
https://mcp.tryrehearsal.ai/mcp — paste it into ChatGPT's Plugins page or Claude's Connectors page and sign in when the browser window opens. The same address works for both.
What is an MCP server in plain words?
A small bridge that lets an AI assistant reach information stored somewhere else. MCP stands for Model Context Protocol, an open standard supported by ChatGPT and Claude. The Rehearsal MCP server lets those apps search what you have saved in Rehearsal, with your permission.
Does ChatGPT support MCP?
Yes. ChatGPT supports MCP servers through the Plugins page in Settings. Add Rehearsal as a server URL, choose OAuth, and it appears as a tool inside your chats.
How do I add a custom connector in Claude?
Open Claude Settings, choose Connectors, select Add custom connector, name it Rehearsal, and paste the server address. Leave the optional OAuth client fields blank — Claude handles sign-in in the browser.
Is my Rehearsal data safe when I connect?
You sign in with OAuth to your own account, so nothing is shared beyond it. The connection searches and reads what you saved — it does not edit or delete anything — and you can disconnect from ChatGPT or Claude at any time.
Why does the Rehearsal tool not show up in my chat?
Confirm the connection shows as enabled in your client — Plugins in ChatGPT, Connectors in Claude — then start a new chat. On the first request, name it directly: “Use Rehearsal to find my notes about pricing.”
What if the sign-in window never opens?
Allow pop-ups for ChatGPT or Claude, retry the authorisation, and check you are signed in to the right Rehearsal account in that browser.
What should I ask first after connecting?
Something only your own collection can answer. “Use Rehearsal to search my voice notes from this month and tell me what I keep coming back to” is a good first question — it proves the connection works and usually shows you something about yourself.
