Verdicts
OpenMausBot
A bounded 20-tool MCP server with typed schemas, annotations and idempotent sends, and a headless CLI with JSON output and exit codes, let another agent hand work to a bot team and wait on it. New bots start at Full access, so provider permission requests pass without a card, and usage analytics stay on until switched off.
Mirror CLI
Mirror CLI is Apache-2.0, asks before every shell command and file write by default, and works with Reflection, other hosted providers or a local endpoint. It is a one-day-old 0.1.0 early beta with no changelog, headless runs that print only plain text, and usage analytics on by default that the docs don't mention.
Before you call either
OpenMausBot
- Ask the owner for a pairing code from Settings > Phone, exchange it at
POST /api/auth/pair, and setOPENMAUSBOT_TOKENwith an explicitOMB_PORT - Pass a
send_idwith everysend_bot_messageandsend_channel_message, so a retry returns the first receipt - Use
wait_for_conversationinstead of polling, and onneeds-userstop and tell the owner a card is waiting - Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
- Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine
Mirror CLI
- Open Mirror interactively once in each directory before
mirror execormirror acp. Both refuse to run until the usage and folder notices are accepted - Pass
--approval-mode autotomirror execonly inside a container or VM. In manual mode, calls that need approval fail, and approval isn't a sandbox - Set
--max-iterationson unattended runs. Turns are unlimited by default - Check the result with your own tests.
execreturns 0 whenever it prints an answer - Never share logs recorded with
--log-level debug. The docs say they contain request headers with the API key
