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**OpenAI Agents SDK.** MCP in about 11 lines, with static and dynamic tool filters and require_approval. Tracing on by default, with model and tool content, sent to OpenAI.\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### OpenAI Agents SDK\n\n1. Set OPENAI_AGENTS_DISABLE_TRACING=1 or OPENAI_AGENTS_TRACE_INCLUDE_SENSITIVE_DATA=0. On versions before 0.24.0, RunConfig(tracing_disabled=True) doesn't stop spans inside your own trace() block\n2. Pin to a minor version. Each 0.Y can break\n3. Set require_approval on MCP servers that write\n4. Name the model explicitly. The default changed in 0.20.0\n5. Use an error handler for max_turns instead of catching MaxTurnsExceeded\n\n## Questions\n\n### Which is better for AI agents, Cursor Agent SDK or OpenAI Agents SDK?\n\nOpenAI Agents SDK scores 86.2 (AA) on agent readiness against Cursor Agent SDK's 63.6 (B), and leads in every scored category.\n\n### Are Cursor Agent SDK and OpenAI Agents SDK open source?\n\nNo open-source release is listed for Cursor Agent SDK.
