Nowledge Mem Claude Desktop Extension

Demo Screenshots

https://github.com/user-attachments/assets/a99a1daa-e73c-429e-a17b-0183b2f9671a

For more details, please refer to the Nowledge Mem Documentation.

End User Installation

See also the end user installation details at Nowledge Mem Documentation: Claude Desktop.

Make sure Nowledge Mem is already running on the same machine, and update Claude Desktop to the latest version.
Download the Nowledge Mem Claude Desktop extension and double-click the .mcpb file to install it.
Restart Claude Desktop once after installation.

Access Mem Anywhere (Remote Access)

By default the extension connects to your local Mem at 127.0.0.1:14242.

For remote access, the extension reads the same shared config file as the nmem CLI:

macOS / Linux: ~/.nowledge-mem/config.json
Windows: %USERPROFILE%\\.nowledge-mem\\config.json

If you start Access Anywhere from Nowledge Mem Desktop on the same machine, this file is usually written for you automatically.

If you need to point Claude Desktop at a remote Mem manually, create the file with:

{
  "apiUrl": "https://mem.example.com",
  "apiKey": "nmem_your_key"
}

Use your server root URL in apiUrl. If you already have an older config ending in /remote-api or /mcp, the extension accepts that too.

Restart Claude Desktop after changing the file.

Troubleshooting

In Claude Desktop, click the + button in the chat box and open Connectors to confirm Nowledge Mem appears.
If it does not, open Settings → Extensions → Advanced Settings and inspect the extension status and logs there.
If you're using Access Anywhere, verify the shared config file above points to the correct URL and key.

Build From Source

The extension uses the Node runtime that ships with Claude Desktop, so end users do not need to install Python or Node.

npm ci
npm test
npm run smoke
npm run pack

For maintainers:

npm run build bundles the bridge into dist/index.js
npm test rebuilds and runs the end-to-end MCP forwarding checks
npm run smoke validates the built dist/index.js against a mock MCP server
npm run pack builds, packages, and audits the final .mcpb
npm run verify:package unpacks the finished bundle and checks the release invariants
npm ci also installs the pinned mcpb packer locally, so npx @anthropic-ai/mcpb pack resolves to the tested version inside this repo
the release archive excludes node_modules/, source files, and stale Python artifacts
