Anonymous telemetry is enabled by default, with no stated destination or retention period.\n\n**Microsoft Agent Framework.** Python 1.21.0 and .NET 1.24.0 are MIT, past 1.0 and released about weekly, with an MCP client, tool approval, checkpointed graph workflows and OpenTelemetry. Breaking changes ship in minor releases, a version User-Agent and a feature-usage token are sent by default, and a high-severity advisory in the .NET declarative workflows package was published on 7 October 2026.\n\n## Before you call either\n\n### CrewAI\n\n1. Set CREWAI_DISABLE_TELEMETRY=true before the first run\n2. Put MCP keys in headers, not in the URL as the docs' Exa example does\n3. Pin a stable version. Development builds share the crewai name on PyPI\n4. Add a PRE_TOOL_CALL hook for any tool that writes or sends\n5. Check the logs for MCP connection warnings. A failed server doesn't stop the agent\n\n### Microsoft Agent Framework\n\n1. Pin exact versions. Minor releases have carried [BREAKING] changes, so read python/CHANGELOG.md or the upgrade guides before moving up\n2. Set `approval_mode=\"always_require\"` on tools and MCP servers that write. The default is `never_require`\n3. Pass `allowed_tools` to `MCPStdioTool` or `MCPStreamableHTTPTool` so only the named MCP tools reach the model\n4. Set `AGENT_FRAMEWORK_USER_AGENT_DISABLED=true` to drop the framework's User-Agent and feature token, or `AGENT_FRAMEWORK_FEATURE_MASK_DISABLED=true` for the token alone\n5. On .NET, use Microsoft.Agents.AI.Workflows.Declarative 1.24.0 or later. Earlier versions could forward protected workflow values to an external MCP server\n\n## Questions\n\n### Which is better for AI agents, CrewAI or Microsoft Agent Framework?\n\nMicrosoft Agent Framework scores 82.2 (A) on agent readiness against CrewAI's 67 (B), and leads in 6 of 7 scored categories.\n\n### Are CrewAI and Microsoft Agent Framework open source?\n\nYes. CrewAI is open source (MIT). Microsoft Agent Framework is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/crewai-vs-microsoft-agent-framework.json, and with the fewest tokens: https://www.anchorterminal.com/compare/crewai-vs-microsoft-agent-framework.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"crewai\", \"b\": \"microsoft-agent-framework\"}`.
