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.

Builds a file path from a variable cairn/code/utils.py:62
    base_str = posixpath.normpath(posixpath.join(importer_dir, import_path))

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.

Cairn — questions

Answers built from our own checks of this server.

Why is there no uptime for Cairn?
Cairn runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is Cairn still maintained?
The author archived this repository on GitHub, meaning it is no longer maintained. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
Is Cairn open source?
Yes — it is published under the GPL-3.0 licence, written in Python and 7 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
