Install Jentic One Beta

Connect the AWS RDS Data API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS RDS Data API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with AWS RDS Data API.

Execute a single SQL statement with named parameters via Execute against an Aurora cluster

Run a parameterized statement across many parameter sets in one call using BatchExecute

Open a transaction with BeginTransaction and thread the transactionId through subsequent calls

For Agents

Run SQL and parameterized batch statements against Aurora Serverless and Aurora DSQL clusters over HTTPS without managing connections.

Use for: I need to run a SELECT against an Aurora Serverless cluster, Insert a row into an Aurora table from a Lambda function, Execute a batch of INSERTs with parameter sets in one call, Begin a transaction on an Aurora cluster and run multiple statements

Not supported: Does not provision databases, manage schemas via DDL workflows, or run SQL on non-Aurora engines - use for HTTPS SQL execution on Aurora Serverless and Aurora DSQL clusters only.

Jentic publishes the only available OpenAPI specification for the AWS RDS Data API, keeping it validated and agent-ready. The RDS Data API runs SQL against Aurora Serverless and Aurora DSQL clusters over HTTPS without persistent database connections or VPC connectivity, using IAM and Secrets Manager for authentication. Six operations cover single-statement execution, batch parameterized execution, transaction begin and commit and rollback, and a legacy ExecuteSql endpoint. It is the right fit for serverless functions, mobile clients, and AI agents that need ad-hoc SQL access without managing a connection pool.

Use Cases

Patterns agents use AWS RDS Data API for, with concrete tasks.

★ Serverless SQL from Lambda

Call SQL from AWS Lambda or any HTTPS-capable client without VPC attachment, NAT, or a connection pool. ExecuteStatement (POST /Execute) takes resourceArn, secretArn, database, sql, and named parameters and returns columnMetadata plus records. The credentials live in Secrets Manager, so the function only needs IAM permissions for rds-data:ExecuteStatement and secretsmanager:GetSecretValue.

Call POST /Execute with resourceArn of the Aurora cluster, secretArn of the credentials secret, database 'app', sql 'SELECT id,email FROM users WHERE id = :id', and parameters [{name:'id',value:{longValue:42}}]

Batch Inserts and Imports

Bulk-load data without paying the per-statement HTTP overhead by using BatchExecute. The API accepts a single sql template and an array of parameterSets and runs the same statement once per set inside one call. Useful for syncing webhook payloads, ETL row inserts, or migration top-ups into Aurora Serverless.

Call POST /BatchExecute with sql 'INSERT INTO events(id, payload) VALUES(:id, :payload)' and parameterSets containing one entry per event

Multi-Statement Transactions

Run several SQL statements atomically over HTTPS by opening a transaction with BeginTransaction, threading the returned transactionId into each Execute call, and committing or rolling back at the end. Common for handling money movement, idempotent upserts, or multi-table writes from a stateless service.

Call POST /BeginTransaction to obtain transactionId, run two Execute calls with that transactionId for INSERT and UPDATE, then POST /CommitTransaction with the same transactionId

AI Agent Database Tool via Jentic

An agent that needs to read or write SQL data uses Jentic to discover the RDS Data API, load Execute, and run parameterized statements against Aurora. Jentic stores the AWS access key in its vault and signs requests with SigV4; the database credentials themselves stay in Secrets Manager and are referenced by ARN, so secrets never enter the agent context.

Use Jentic to search 'execute sql against aurora serverless', load Execute, and execute it with resourceArn, secretArn, database, and parameterized sql

Why Jentic?

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

Credential isolation

Your AWS access keys are stored once, encrypted, by your own Jentic One instance and used to produce a SigV4 signature per request, while the database credential stays in Secrets Manager referenced by ARN. Neither the AWS secret access key nor the database password enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'run SQL against an Aurora Serverless cluster', and Jentic returns Execute with its parameter schema for resourceArn, secretArn, database, sql, and parameters so the agent calls the right endpoint directly.

FAQs

Specific to using AWS RDS Data API through Jentic.

Why is there no official OpenAPI spec for the AWS RDS Data API?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call the AWS RDS Data API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the RDS Data API use?

The API uses AWS SigV4 HMAC request signing for the HTTPS call, plus a Secrets Manager secretArn parameter that holds the database username and password. Through Jentic, AWS credentials are stored in the vault and SigV4 signatures are produced per request.

Which databases does the RDS Data API support?

The Data API supports Aurora Serverless v1 and v2 for PostgreSQL and MySQL, and Aurora DSQL. It does not work against provisioned Aurora clusters running classic engines or other RDS engines like Oracle, SQL Server, or MariaDB.

Can I run multi-statement transactions?

Yes. POST /BeginTransaction returns a transactionId; pass that transactionId into each POST /Execute call and finish with POST /CommitTransaction or POST /RollbackTransaction. Transactions time out after a few minutes of inactivity.

What are the rate limits for the RDS Data API?

The Data API enforces per-account, per-region quotas on simultaneous connections and result-set size (around 1 MB). Throttled requests return BadRequestException or 429 with a throttling message; back off and retry, and use BatchExecute to reduce per-row request volume.

How do I run a parameterized query through Jentic?

Search Jentic for 'execute sql against aurora serverless', load Execute, and execute it with resourceArn, secretArn, database, sql containing named placeholders, and parameters. Install with pip install jentic; AWS credentials come from your Jentic One instance.

Can I limit what my agent is allowed to do with the AWS RDS Data API?

Yes. Because Jentic One is self-hosted, you decide which of the six operations your agent may call, so you can grant only Execute and BatchExecute for statement execution and withhold everything else. Transaction-control operations such as BeginTransaction, CommitTransaction, and RollbackTransaction are available to the agent only when you choose to include them. The cluster ARN, secret ARN, and SQL all travel in the request body under rules you set, keeping the agent scoped to the exact access it needs.
