It's closed source, every model turn runs through Cursor's backend on a Cursor plan, local sandboxing is off by default, and the changelog has two entries.\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## Before you call either\n\n### Cursor Agent SDK\n\n1. Install `@grok/agent-sdk`, not `@cursor/agent-sdk` from the launch post. That name answers 404 on npm\n2. Set `local.sandbox` before a turn reads webhook payloads, pull request diffs or chat. Without it shell commands auto-approve with the host's credentials\n3. Give every tool an `effect`. A tool without one counts as a write, runs once and is stubbed in dry runs\n4. Start `agent-sdk serve` with `--bearer-token` on any shared host. `--allow-anonymous` admits every caller as one principal\n5. Delete bot/hooks/memory.ts when sessions serve different people. The journal shares each turn's message and result with later turns\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## Questions\n\n### Which is better for AI agents, Cursor Agent SDK or LangGraph?\n\nLangGraph scores 70.6 (BB) on agent readiness against Cursor Agent SDK's 63.6 (B), and leads in 5 of 7 scored categories. Cursor Agent SDK leads on agent ergonomics and security \u0026 auth.\n\n### Are Cursor Agent SDK and LangGraph open source?\n\nNo open-source release is listed for Cursor Agent SDK. LangGraph is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cursor-agent-sdk-vs-langgraph.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cursor-agent-sdk-vs-langgraph.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cursor-agent-sdk\", \"b\": \"langgraph\"}`.
