Arcaeon MCP Server

Arcaeon is an MCP integration. A record of what an agent did that the agent cannot quietly rewrite, and a way for anyone to check.

Packages and local setup

The published pypi package is arcaeon, version 0.9.0. Its declared MCP transport is stdio.

The package declares ARCAEON_KEY: Witness API key for the two paid tools (witness_pin, witness_renew). Free tools work without it..

This package has launch arguments in its registry record. Use the maintainer’s configuration for those arguments rather than launching it with only the package name.

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
