Two critical CVEs in 2026, one of them in tool confirmation itself.\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### Agent Development Kit (ADK)\n\n1. Upgrade to 2.5.0 or later before relying on tool confirmation\n2. Always pass tool_filter to McpToolset\n3. Pin a 2.x minor and read the changelog's breaking section before each bump\n4. Install the bigquery-analytics extra if you use pyarrow, since 2.7.0\n5. Keep ADK Web off public interfaces, or run 1.28.1 or later at the least\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, Agent Development Kit (ADK) or Microsoft Agent Framework?\n\nMicrosoft Agent Framework scores 82.2 (A) on agent readiness against Agent Development Kit (ADK)'s 74.7 (BB), and leads in 5 of 7 scored categories.\n\n### Are Agent Development Kit (ADK) and Microsoft Agent Framework open source?\n\nYes. Agent Development Kit (ADK) is open source (Apache-2.0). Microsoft Agent Framework is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/google-adk-vs-microsoft-agent-framework.json, and with the fewest tokens: https://www.anchorterminal.com/compare/google-adk-vs-microsoft-agent-framework.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"google-adk\", \"b\": \"microsoft-agent-framework\"}`.
