MCP server for pūrmemo - AI conversation memory that works everywhere. Save and recall conversations across Claude Desktop, Cursor, and other MCP-compatible platforms. Intelligent context extraction, smart titles, living documents. Exposed over MCP by the purmemo mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
That's it for installing. The script handles everything — it'll install Node if you don't have it, set up the purmemo command, and tell you when it's done.
Everything the assistant can do here goes through one of these:
macOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%\Claude\claude_desktop_config.jsonPlan — PriceFree — $0Pro — $19/monthYou will need one environment variable: PURMEMO_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Purmemo MCP's toolset — macOS, Windows, Plan and 2 more — is a fair guide to whether it matches your workflow. It is maintained by purmemo-ai; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
