Nothing serious here today

Today is the operative word: we check Aethis MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Optional settings from the registry entry, left out of the block above: AETHIS_API_KEY (API key for rule authoring tools (create/generate/publish). Decision tools (decide/schema/explain on public rulesets) work without a key. Get one via 'aethis login' in aethis-cli), AETHIS_BASE_URL (API base URL. Defaults to https://api.aethis.ai — override for self-hosted or staging).

Aethis MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Aethis MCP?

Aethis MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package aethis-mcp was installed 41 times last week.

How do I connect Aethis MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls aethis-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Aethis MCP?

The npm package aethis-mcp was installed 41 times in the last week. Week over week that is -37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Aethis MCP open source?

Yes — it is published under the MIT licence, written in TypeScript, 1 stars on GitHub and 8 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
