Ahead on

  • Transparency & trust, 71 against 59

Watch for

Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026

OpenMausBot B

Best for A person or an outside agent who wants several CLI agents (Claude Code, Codex, Grok, ACP CLIs) organised as named bots with their own computers, routines and approvals, driven by MCP or a CLI.

Ahead on

  • Reliability, 60 against 55
  • Schema & documentation, 90 against 72
  • Agent ergonomics, 77 against 72
  • Payments & pricing, 50 against 40

Also in its favour

Verdicts

GitHub Copilot CLI

Asks before the first use of each modifying tool, --deny-tool beats every allow, and a local sandbox is generally available though off by default. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

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.

Before you call either

GitHub Copilot CLI

  1. Pass --deny-tool for anything destructive. It wins over --allow-all-tools and --allow-tool
  2. Turn on the sandbox with /sandbox enable or --sandbox. It's off by default
  3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
  4. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026
  5. Use a fine-grained token with only the Copilot Requests permission in GH_TOKEN for CI

OpenMausBot

  1. Ask the owner for a pairing code from Settings > Phone, exchange it at POST /api/auth/pair, and set OPENMAUSBOT_TOKEN with an explicit OMB_PORT
  2. Pass a send_id with every send_bot_message and send_channel_message, so a retry returns the first receipt
  3. Use wait_for_conversation instead of polling, and on needs-user stop and tell the owner a card is waiting
  4. Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
  5. Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
