It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default.\n\n**Leon.** Connected-app credentials are encrypted per profile and the Gmail connection is read-only. The 2.0 Developer Preview has no tagged release, runs tools and a 30-minute proactive pulse with no approval step, listens on every network interface with client authentication off, and sends telemetry by default.\n\n## Before you call either\n\n### Atticus\n\n1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box\n2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac\n3. Point a user who wants pinned versions to Settings \u003e About \u0026 Updates to turn off self-update\n\n### Leon\n\n1. Clone the develop branch for 2.0. `npm install --global @leon-ai/cli` and docs.getleon.ai install and describe the legacy 1.0 betas\n2. Set `client_interface.auth.enabled: true` and a `LEON_PROFILE_TOKEN` before the machine joins a shared network. The server binds 0.0.0.0\n3. Set `telemetry_enabled: false` and `runtime.pulse_enabled: false` in the profile `config.yml` for an unattended or private run\n4. Use `availability.tools.allowed` to limit tools. Shell, file writes, computer use and browser control are otherwise available to the agent with no approval prompt\n5. Back up `LEON_CONNECTIONS_ENCRYPTION_KEY` from the profile `.env`. Without it the stored connections cannot be read\n\n## Questions\n\n### Which is better for AI agents, Atticus or Leon?\n\nAtticus scores 42.9 (E) on agent readiness against Leon's 41 (E), and leads in 3 of 7 scored categories. Leon leads on schema \u0026 documentation and agent ergonomics.\n\n### Are Atticus and Leon open source?\n\nYes. Atticus is open source (MIT). Leon is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/atticus-vs-leon.json, and with the fewest tokens: https://www.anchorterminal.com/compare/atticus-vs-leon.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"atticus\", \"b\": \"leon\"}`.
