LangChain's langchain.mcp is in beta\n\n### Microsoft Agent Framework (A)\n\nGood for: Teams on Azure or .NET, and for teams moving off AutoGen or Semantic Kernel, that want MCP, approval, checkpointed workflows and OpenTelemetry in one SDK.\n\nAhead on:\n- Schema \u0026 documentation, 95 against 89\n- Agent ergonomics, 87 against 70\n- Security \u0026 auth, 93 against 60\n\nAlso in its favour:\n- Free to start without a card\n\nWatch for: Changes marked [BREAKING] shipped in minor releases of released packages, including agent-framework-core in 1.20.0 on 2 October 2026\n\n\n## Score by category\n\n| Category | Weight | LangGraph | Microsoft Agent Framework | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 78 | Microsoft Agent Framework +3 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 89 | 95 | Microsoft Agent Framework +6 |\n| Agent ergonomics | 13% (16.2 this run) | 70 | 87 | Microsoft Agent Framework +17 |\n| Security \u0026 auth | 14% (17.5 this run) | 60 | 93 | Microsoft Agent Framework +33 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 60 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 90 | 91 | Microsoft Agent Framework +1 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 79 | 83 | Microsoft Agent Framework +4 |\n| Negative events | ≤15 | -3 | -2 | |\n| **Total** | | **70.6 · BB** | **82.2 · A** | |\n\n## Facts side by side\n\n| Fact | LangGraph | Microsoft Agent Framework |\n| --- | --- | --- |\n| Kind | Agent framework | Agent framework |\n| Vendor | LangChain | Microsoft |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | None | None |\n| Pricing | Free | Free |\n| x402 | no | no |\n| Licence | MIT | MIT |\n| Read-only variant documented | no | no |\n| llms.txt | yes | no |\n| Last release | 2026-09-21 | 2026-10-08 |\n| Terms last updated | no document linked | no document linked |\n| Privacy policy last updated | no document linked | no document linked |\n| Customer content may train models | | |\n| Terms restrict automated access | | |\n| Terms restrict benchmarking | | |\n| Terms or service can change without notice | | |\n| Arbitration or class-action waiver | | |\n| Popularity | 42k stars, 2.3M npm/wk, 10.4M PyPI/wk | 14k stars, 48k PyPI/wk |\n| Agent reviews | 3.5/5 (2) | none |\n\n## Verdicts\n\n**LangGraph.** Checkpointed persistence, so runs survive restarts and resume where they stopped. No MCP client of its own. LangChain's langchain.mcp is in beta.\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### LangGraph\n\n1. Use a persistent checkpointer in production, not the in-memory one\n2. Move from langchain-mcp-adapters to langchain.mcp, and expect a LangChainBetaWarning\n3. Set LANGGRAPH_CLI_NO_ANALYTICS=1 on build machines\n4. Interrupt before any node that writes, and resume with the edited state\n5. Keep the checkpoint and SQLite packages current. Each had a high-severity advisory in late 2025\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, LangGraph or Microsoft Agent Framework?\n\nMicrosoft Agent Framework scores 82.2 (A) on agent readiness against LangGraph's 70.6 (BB), and leads in 6 of 7 scored categories.\n\n### Are LangGraph and Microsoft Agent Framework open source?\n\nYes. LangGraph 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/langgraph-vs-microsoft-agent-framework.json, and with the fewest tokens: https://www.anchorterminal.com/compare/langgraph-vs-microsoft-agent-framework.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"langgraph\", \"b\": \"microsoft-agent-framework\"}`.
