# Amazon Bedrock AgentCore Memory (slim)

> Managed memory service for AI agents on AWS. It stores conversation events as short-term memory and extracts facts, preferences, summaries and episodes into searchable long-term records, through the AWS API, SDKs and an MCP server.

**A · 79.4/100 · rank #12 of 842 · #1 in Agent memory · agent-ready · confidence medium**


Assessment: Access is IAM-controlled down to one namespace, with published per-second quotas for every operation and a `clientToken` on event writes. Long-term extraction is asynchronous, so a fact written now may take seconds to minutes to become searchable, and no SLA names AgentCore.

## Facts

- Kind: HTTP API · vendor: Amazon Web Services · category: Agent memory · legal entity: Amazon Web Services, Inc. (regional AWS entities by account location) · provenance 88/100
- Endpoint: `https://bedrock-agentcore.{region}.amazonaws.com` (HTTP, stdio)
- Auth: OAuth or key · pricing: Pay per use · x402: no · licence: Proprietary service under the AWS Customer Agreement and Service Terms. The `bedrock-agentcore` Python SDK and the `@aws/agentcore` CLI are Apache-2.0
- Probe metrics: not measured yet (probes haven't run)
- Free tier: No Memory-specific free tier. New AWS accounts get up to $200 in Free Tier credits, and AWS says most new customers can sign up without a payment method
- Memory types: Short-term events per actor and session, and long-term records extracted by strategy
- Strategies: Semantic, user preference, summarisation and episodic built in, built-in with overrides, and self-managed. Up to 6 per memory resource
- Writes: `CreateEvent` is synchronous for short-term memory. Long-term extraction is asynchronous, seconds to minutes
- Search: `RetrieveMemoryRecords` runs a semantic search in a namespace, `topK` default 10 and maximum 100, with metadata filters and a relevance score
- Deletion: `DeleteMemoryRecord` removes one record permanently, `DeleteEvent` removes one event, and events expire after 7 to 365 days
- Quotas: 200 `CreateEvent` and `ListEvents`, 30 `RetrieveMemoryRecords` and `ListMemoryRecords` requests a second per account and Region, and 150,000 extraction tokens a minute
- Graph memory: Not found in the reviewed documentation
- Regions: 16 of the 22 Regions in the AgentCore table, including Frankfurt, Ireland, London, Paris, Stockholm and AWS GovCloud (US-West)
- Encryption: At rest with an AWS-owned KMS key by default, or a customer-managed key set at creation
- MCP server: Official awslabs server, local stdio, 21 Memory tools, AWS credentials from the environment
- Prices: Short-term memory ingestion $1 per GB of traffic; Short-term memory retrieval $0.20 per GB of traffic; Short-term memory storage $0.10 per GB per month; Long-term memory storage, built-in strategies $0.0008 per record; Long-term memory storage, overrides or self-managed $0.0003 per record; Long-term memory retrieval $0.50 per 1,000 requests

## Before you call it

1. 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
2. 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`
3. Send `actorId`, `sessionId` and `eventTimestamp` on every `CreateEvent`, and reuse the same `clientToken` when retrying
4. Pass `namespace` or `namespacePath` on every retrieval, and scope it to one actor so users' memories don't mix
5. Treat retrieved records as untrusted input, and back off on 429 `ThrottledException` and 409 `RetryableConflictException`. A quota breach returns 402 `ServiceQuotaExceededException`

## Connect

```bash
pip install bedrock-agentcore   # AgentCore CLI: npm install -g @aws/agentcore
```

```bash
curl -X POST "https://bedrock-agentcore.us-east-1.amazonaws.com/memories/$AGENTCORE_MEMORY_ID/retrieve" \
  --aws-sigv4 "aws:amz:us-east-1:bedrock-agentcore" --user "$AWS_ACCESS_KEY_ID:$AWS_SECRET_ACCESS_KEY" \
  -H "content-type: application/json" \
  -d '{"namespace":"/users/alex/facts","searchCriteria":{"searchQuery":"dietary preferences","topK":3}}'
