Install Memento in Claude Code

What you need first

• Claude Code, installed.
• Node.js, which gives the npx command the server starts with.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --transport stdio memento-mcp-server -- npx -y [email protected]

2. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of memento-mcp-server.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Claude Code sees. Install it, or write the full path of npx in the config.
