What the code does

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

if (-not $env:NEWAPI_JUDGE_KEY) { $jk = "sk-tU6bGHCw6cMotQvtAa502W4hEtMJe4PSkWbWWY5iuv0f4Bgf" } else { $jk = $env:NEWAPI_JUDGE_KEY }
Capabilities

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.

Runs an external command bin/compass-mcp.js:19, npm/bin/cli.js:20
    const r = spawnSync(cmd, ['--version'], { stdio: 'ignore' });
    with open(os.path.join(CAP_MEM_DIR, fname), "w", encoding="utf-8") as f:
    sql = _SELECT + where + " ORDER BY created_at ASC"

    cur = bus_conn.cursor()

Nautilus Compass Memory — questions

Answers built from our own checks of this server.

Why is there no tool list for Nautilus Compass Memory?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 98.7% of checks in the last 24 hours got a reply.
Is Nautilus Compass Memory working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 75 of 76 checks got a reply (98.7%), average response time 1818 ms. The bar chart above shows every period we have measured.
How do I connect Nautilus Compass Memory?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.
Does Nautilus Compass Memory need an API key?
Yes. Every time we knock, Nautilus Compass Memory answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How many people use Nautilus Compass Memory?
The pypi package nautilus-compass was installed 715 times in the last week. Week over week that is -18%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Nautilus Compass Memory open source?
We cannot say either way: written in Python, 207 stars on GitHub and 22 open issues, but we could not determine the licence, and without one the code is not open source by default.
