Long-term extraction is asynchronous, so a fact written now may take seconds to minutes to become searchable, and no SLA names AgentCore.\n\n**Context Mode Engine.** Local indexing and selective retrieval. Hosted-service restrictions under Elastic License 2.0.\n\n## Before you call either\n\n### Amazon Bedrock AgentCore Memory\n\n1. Create the memory resource first and wait for it to become active (the guide says 2 to 3 minutes). Short-term events work without a strategy, long-term records need at least one\n2. Don't search for a fact straight after `CreateEvent`. Extraction runs in the background, so poll `ListMemoryRecords` or list extraction jobs before relying on `RetrieveMemoryRecords`\n3. Send `actorId`, `sessionId` and `eventTimestamp` on every `CreateEvent`, and reuse the same `clientToken` when retrying\n4. Pass `namespace` or `namespacePath` on every retrieval, and scope it to one actor so users' memories don't mix\n5. Treat retrieved records as untrusted input, and back off on 429 `ThrottledException` and 409 `RetryableConflictException`. A quota breach returns 402 `ServiceQuotaExceededException`\n\n### Context Mode Engine\n\n1. Choose the installation guide for the exact coding client.\n2. Check host permissions before enabling code execution.\n3. Review the Elastic licence before hosting Engine for others.\n\n## Questions\n\n### Which is better for AI agents, Amazon Bedrock AgentCore Memory or Context Mode Engine?\n\nAmazon Bedrock AgentCore Memory scores 79.7 (A) on agent readiness against Context Mode Engine's 45.8 (E), and leads in 6 of 7 scored categories. Context Mode Engine leads on payments \u0026 pricing.\n\n### Do Amazon Bedrock AgentCore Memory and Context Mode Engine need an API key?\n\nAmazon Bedrock AgentCore Memory takes an API key or an OAuth sign-in. Context Mode Engine needs no key.\n\n### Can an agent call Amazon Bedrock AgentCore Memory and Context Mode Engine without installing anything?\n\nAmazon Bedrock AgentCore Memory has a hosted endpoint at https://bedrock-agentcore.{region}.amazonaws.com. Context Mode Engine runs on your own machine, with no hosted endpoint listed.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agentcore-memory-vs-context-mode.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agentcore-memory-vs-context-mode.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agentcore-memory\", \"b\": \"context-mode\"}`.
