Cursor

Wire mnemostack into Cursor as an MCP server. Cursor reads MCP servers from its own settings, not from Claude Desktop's config.

Install

1. Make sure the binary and a working backend are ready:

   pip install 'mnemostack[mcp]'
   mnemostack health --provider gemini
   

2. Open Cursor → Settings → MCP (or edit ~/.cursor/mcp.json directly).

3. Add the server entry:

   {
     "mcpServers": {
       "mnemostack": {
         "command": "mnemostack",
         "args": [
           "mcp-serve",
           "--provider", "gemini",
           "--collection", "my-memory"
         ],
         "env": {
           "GEMINI_API_KEY": "your-key-here"
         }
       }
     }
   }
   

4. Reload Cursor (Cmd/Ctrl+Shift+P → Reload Window). The server should appear in the MCP panel with a green dot.

Verify

Open the Cursor chat and ask:

What MCP tools do you have from mnemostack?

Expected: health, search, answer, feedback (and graph_query plus graph_add_triple if a Memgraph URI was set).

Quick smoke test:

Search mnemostack for "VPN failover", tier 2.

The model should invoke the tool and return short (~40 char) snippets with source ids.

Uninstall

Remove the mnemostack block from ~/.cursor/mcp.json (or toggle it off in the Cursor MCP settings UI) and reload the window.

Troubleshooting

• Server stays red: Cursor doesn't always show stderr — run the same command manually in a terminal to see what's wrong: mnemostack mcp-serve --provider gemini --collection my-memory.
• PATH differs in GUI: Cursor on macOS inherits a different PATH than Terminal. Use an absolute path for command (e.g. output of which mnemostack).
• Model can't find the tool: some Cursor versions gate MCP behind per-chat tool toggles. Check the tools icon in the chat input.
