It is at 0.12.12 after 98 releases in 90 days, two of them breaking on 7 October 2026. No MCP client was found in the package, and code tools an agent writes run in an in-process node:vm context.\n\n**Claude Agent SDK.** Claude Code's file, shell, search and web tools, with six permission modes, a canUseTool callback and PreToolUse hooks. Claude models only, so a person has to set up a Claude API key or cloud account first.\n\n## Before you call either\n\n### AgentOS\n\n1. Pin an exact version of @framers/agentos. Feature commits ship as patch releases while it is 0.x, and breaking changes ship as minors\n2. Leave emergentConfig.allowSandboxTools off unless forged code runs through an executor that isolates. The default executor shares the host process\n3. Pass your own ICheckpointStore to compile() for runs that must survive a restart. The default store is in memory\n4. Set hitl.approvals.beforeTool for tools that write, and choose a handler. No approval gate is on by default\n5. Use Node 22 or newer, and set a provider key such as OPENAI_API_KEY or ANTHROPIC_API_KEY. The provider is detected from the environment\n\n### Claude Agent SDK\n\n1. Set DISABLE_TELEMETRY=1 before the first run on the Claude API\n2. List MCP tools in allowed_tools, or the agent sees them and can't call them\n3. Pass permission_mode explicitly. An unset mode can start in auto mode since TypeScript 0.3.286\n4. Pin the version. Releases land almost daily and some get yanked\n5. Check the init message for MCP servers in failed or needs-auth. They don't raise\n\n## Questions\n\n### Which is better for AI agents, AgentOS or Claude Agent SDK?\n\nAgentOS scores 75.3 (BB) on agent readiness against Claude Agent SDK's 72.1 (BB), and leads in 3 of 7 scored categories.
