Connect ChatGPT to Mempipe

To connect ChatGPT to Mempipe, use the ChatGPT desktop app. Open Settings, then MCP servers, and choose Add server. Paste your Space’s address from Mempipe’s MCP Endpoint page as a Streamable HTTP server, save, and restart ChatGPT. Then choose Authenticate to sign in to Mempipe and approve access. ChatGPT can then search and read the files in that Space and cite them in its answers.

To browse your files inside ChatGPT, choose files for a chat, and save files you attach, use Mempipe Notebook, Mempipe’s app for ChatGPT, instead.

Before you start

• The ChatGPT desktop app. OpenAI’s MCP guide covers its MCP settings. On the web, ChatGPT’s custom MCP server setting adds Mempipe for all your Spaces, with the notebook. OpenAI describes it for developers testing their own apps. See Use Mempipe Notebook in ChatGPT.
• A Mempipe Space with files in it, and the Mempipe account you use to open it. See Upload files to a Space.

Add Mempipe to ChatGPT

1. Copy the Space’s address.

   In Mempipe, open the Space. Choose Pipeline in the left rail, then MCP Endpoint. Choose Add beside ChatGPT Desktop. The window shows the name to give the server, such as mempipe-acme-research-research. Choose Copy URL.

   

   Mempipe's Add to ChatGPT Desktop window has the name and address to use.

2. Add the server in ChatGPT.

   In the ChatGPT desktop app, open Settings, then MCP servers, and choose Add server. Enter the name from the Mempipe window.

3. Paste the address, then save and restart.

   Choose Streamable HTTP and paste the address. Choose Save, then Restart. ChatGPT loads the server when it restarts, so don’t skip the restart.

4. Authenticate.

   In MCP servers, choose Authenticate beside the Mempipe server. Your browser opens Mempipe. Sign in if asked, then on Allow this client access to Mempipe? choose Approve access.

   To let ChatGPT save notes and wiki pages, tick Create and replace Markdown, SQL, and chart files in this Space before you approve. What a connected AI can read and change explains the choice.

5. Ask a question.

   In a new chat, type /mcp to check that the server and its tools are listed. Then name the server in your question:

   Use the mempipe-ORG-SPACE server. Search my files for what they say about [topic], and answer with the citation links it returns.

ChatGPT’s answers now link to the passages it used, and each link opens the passage in Mempipe. Open a citation and check its source shows what to check.

The ChatGPT desktop app shares its MCP servers with Codex, so a server you add here also appears in Codex. See Connect Codex to Mempipe.

If something goes wrong

• The server doesn’t appear in chats. Restart ChatGPT. It loads new servers only when it starts.
• The server still needs signing in. Choose Authenticate again in MCP servers.
• The sign-in page asks for a password you don’t have. Choose Sign in on the Mempipe app and sign in there, in the same browser. Then choose Authenticate again. See If the connection fails for other sign-in problems.
• ChatGPT says it can’t save files. You approved read access only. See how to add write access.
