01 · Install Purmemo

before you install - you'll need

PURMEMO_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add purmemo-ai-purmemo-mcp -- npx -y purmemo-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "purmemo-ai-purmemo-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "purmemo-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package purmemo-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.purmemo-ai is GitHub-verified and matches the repo owner

06 · Purmemo FAQ

What is Purmemo?

Memory for your AI tools. Claude remembers who you are, what you're working on, and what you said last time - across every session, on every platform. It runs locally over stdio via the published package.

Is Purmemo still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-03 and it shipped 3 releases in the last 90 days. We re-verify nightly.

How do I install Purmemo?

Run `npx -y purmemo-mcp`. The README documents one environment variable (PURMEMO_API_KEY) to set first. You can also paste the ready-made client config above.

Does Purmemo run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
