Cursor forgets. Here's how the next chat can remember.
Last updated September 26, 2026.
The blank chat
Open a new Cursor Agent tab and yesterday is gone. The model can still be sharp inside one thread. What usually does not travel is your repo: the convention you already corrected, the architecture call, the gotcha that cost an afternoon. That is the job here — next session, your codebase — not a claim that Cursor has no memory features at all.
What Memento is here
Memento at mementoagi.com is hosted memory for coding agents over MCP. The server URL is https://api.mementoagi.com/mcp. You sign in, take an API key, and add one mcp.json entry. Memory is markdown pages you can read and edit on the web. Memento is not in the official Cursor marketplace yet.
Search results mix this product with other GitHub projects that share the name. gannonh/memento-mcp is an abandoned Neo4j MCP server. runmemento.com is local SQLite. iAchilles, lfrmonteiro99/memento-mcp, and shane-farkas/memento-memory are different local tools. The hosted product is mementoagi.com.
Install
- Create a free account at https://mementoagi.com/signup.
- After sign-in, open Getting Started for Cursor. That page is login-only because the paste snippet embeds your key. Signed-out visits redirect to
/signup. - Copy the
mcpServersJSON from that page into Cursor's MCP config, or use the Install button if your key is present. Empty-key deeplinks do not fire. - The public marketplace plugin may still be an older build until the mementoagi GitHub repo is pushed. The paste-JSON path on Getting Started is the one that matches current pangea.
The live URL is /getting-started?ide=cursor. The older dashboard alias is gone.
First handshake
Connected means the client completed initialize, tools/list, and at least one tools/call against https://api.mementoagi.com/mcp with your key. A signup row or a last-used timestamp is not the handshake.
This session
Once the server is connected, treat memory as part of the work:
full-search(or the client's equivalent recall) before guessing conventions you already wrote down.remember/write-nodewhen a decision, gotcha, or architecture note should survive this thread.
If the page the agent wrote is wrong, open it on the web and fix it. The next recall reads the corrected page.
Next session
Open a new Agent chat on the same key. Run wake-up / full-search on the topic you stored. That is the “it remembered” moment: the new thread can see yesterday's notes without you pasting the thread back in.
