Memory MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 252 installs a week from npm. Last commit 30 Oct 2026.
Persistent memory for AI agents - save once, recall in every session, project and tool.
What the code does

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
const listed = spawnSync(command, args, {
return fs.readdirSync(folder);
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
