About Diavlos

Diavlos is an MCP server published by the GitHub account harisnopen. Signed messages between AI agents. Dangerous actions wait for a human-signed approval.

It runs on your own machine: your AI client starts it from the cargo package diavlos at version 2.1.1.

It asks for no keys or passwords.

Version 2.1.1 was published on 28 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 3 pass, 1 warn, 0 fail, 3 info. How we check.

What it asks for

Variable	Required	Secret	Description
`DIAVLOS_HOME`	No	No	Data directory. Defaults to ~/.diavlos. Keep it short: the helper's Unix socket path lives inside it and the kernel caps that at 107 bytes.
`DIAVLOS_AS`	No	No	Which local key to act as. Created on first use. Defaults to 'default'.
