For Agents

Store and query schemaless attribute data in Amazon SimpleDB domains. Agents can create domains, put and batch-put attributes, fetch attributes by item, and run Select queries.

Quickstart

Get started with Amazon SimpleDB in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"store and query schemaless data in amazon simpledb"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with Amazon SimpleDB API.

Create and delete SimpleDB domains that hold structured item-attribute data

Write attributes to items using PutAttributes and BatchPutAttributes for bulk loads

Read attributes for a specific item with GetAttributes including consistent-read mode

Run Select queries with SQL-style predicates over a domain to return matching items

Jentic publishes the only available OpenAPI specification for Amazon SimpleDB, keeping it validated and agent-ready. Amazon SimpleDB is a schemaless, automatically indexed key-value data store that exposes domain, item, and attribute primitives over a query API. Agents can create domains, put and get attributes on items, run select-style queries, and perform batched mutations without managing servers, indexes, or replication. SimpleDB targets small-to-medium structured datasets where simplicity and elasticity matter more than transactional joins.

Use Cases

Patterns agents use Amazon SimpleDB API for, with concrete tasks.

★ Lightweight Metadata Store for Application Objects

Use SimpleDB as a schemaless catalog for object metadata that does not justify a relational database. Applications create one domain per logical entity, write attributes via PutAttributes, and query with Select to retrieve matching items. SimpleDB indexes every attribute automatically, so adding new fields needs no migration and queries do not require pre-defined indexes.

Create a domain named 'product-catalog', PutAttributes for item 'sku-1001' with name, price, and category, then run Select to fetch all items where category = 'audio'.

Configuration and Feature Flag Storage

Store feature flags, environment-scoped configuration, and small lookup tables in SimpleDB so multiple services can read and update them without operating a database. BatchPutAttributes loads many flags at once and consistent reads ensure freshly written values are returned on the next GetAttributes call. Suitable for small-to-mid scale systems where feature flag volume is bounded.

BatchPutAttributes into the 'feature-flags' domain to set 10 flag values for the staging environment, then GetAttributes with ConsistentRead=true to verify the writes.

Bulk Cleanup and Domain Lifecycle Management

Operations teams use SimpleDB to maintain domains over time: rotating expired records with BatchDeleteAttributes, decommissioning domains with DeleteDomain, and auditing capacity via DomainMetadata. Because SimpleDB pricing scales with stored attributes, periodic cleanup keeps cost predictable.

Call DomainMetadata on 'audit-logs', then BatchDeleteAttributes for any item whose timestamp attribute is older than 90 days.

AI Agent Schemaless Workspace via Jentic

AI agents using Jentic can treat SimpleDB as scratch storage for task state, intermediate results, and per-session memory. Through Jentic, the agent searches for the SimpleDB write or query operation by intent, loads the input schema, and executes against the vault-stored AWS credentials. No SDK or signing logic is needed in the agent runtime.

Search Jentic for 'put attributes on a SimpleDB item', load the PutAttributes schema, and write three attributes for item 'session-42' in the 'agent-memory' domain.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

AWS access key ID and secret are stored encrypted in the Jentic vault. Agents never see the raw keys — Jentic signs each SimpleDB request with SigV4 on the agent's behalf and returns only the response payload.

Intent-based discovery

Agents search by intent (for example, 'store key value data in simpledb' or 'run a select query') and Jentic returns the matching SimpleDB operations with their parameter schemas, so the agent can invoke PutAttributes or Select without browsing the AWS reference.

Time to first call

Direct SimpleDB integration: 1-2 days to set up SigV4 signing, the Query API serializer, and error handling. Through Jentic: under 30 minutes — search, load the operation schema, and execute.

Alternative

Amazon DynamoDB Accelerator (DAX)

DynamoDB cluster cache for high-throughput key-value workloads where SimpleDB scale would not suffice

Choose DAX with DynamoDB when single-digit millisecond reads at high QPS matter; use SimpleDB only for small, schemaless metadata stores

Alternative

Amazon DocumentDB

MongoDB-compatible document database for richer query patterns than SimpleDB Select supports

Pick DocumentDB when documents have nested structure or need indexing strategies SimpleDB cannot express

Complementary

AWS Lambda

Serverless functions that read and write SimpleDB attributes in response to events

Use Lambda alongside SimpleDB to wrap PutAttributes calls in event-triggered logic without operating servers

FAQs

Specific to using Amazon SimpleDB API through Jentic.

Why is there no official OpenAPI spec for Amazon SimpleDB?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Amazon SimpleDB via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Amazon SimpleDB use?

Amazon SimpleDB uses AWS Signature Version 4 (HMAC-based request signing) with an access key ID and secret access key. Through Jentic, these credentials are stored encrypted in the vault and never enter the agent's context — the agent receives a scoped session and Jentic signs each request before it reaches the SimpleDB endpoint.

Can I run SQL-style queries against the Amazon SimpleDB?

Yes. The Select action accepts a SQL-like expression over a single domain (for example, 'select * from product-catalog where category = "audio"') and returns matching items with their attributes. Joins across domains are not supported — design one domain per logical entity.

What are the rate limits for the Amazon SimpleDB?

SimpleDB throttles based on per-domain throughput rather than fixed per-second limits. Each domain is capped at 10 GB of data and roughly 25 writes per second per item; BatchPutAttributes accepts up to 25 items per call. Beyond that, requests are throttled with a ServiceUnavailable response and should be retried with exponential backoff.

How do I write a batch of items into SimpleDB through Jentic?

Through Jentic, search for 'batch put attributes simpledb', load the BatchPutAttributes input schema, then execute a single call with up to 25 items in the Items array. Jentic handles the SigV4 signing and returns the response with no additional AWS SDK setup.

Is the Amazon SimpleDB free?

SimpleDB has a free tier covering the first 25 machine hours, 1 GB of storage, and 1 GB of data transfer per month. Beyond that, AWS charges for machine hours consumed by queries, stored data, and data transfer. Pricing is documented at https://aws.amazon.com/simpledb/pricing/.
