What it does

Connecting Lambda To Dynamodb is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Connects an AWS Lambda function to DynamoDB with IAM roles, stream event source mapping, and read/write permissions. Use when setting up Lambda-DynamoDB integration, processing DynamoDB stream events, or deploying serverless event-driven architectures.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/lambda-dynamodb-connection.md`).

It sits in Databases, covering NoSQL databases and Serverless. It works with Amazon DynamoDB and AWS Lambda. The repository describes itself as: Official, AWS-supported MCP servers, skills, and plugins to help AI agents build on AWS. The licence is Apache-2.0.

When your agent uses it

  • Setting up Lambda-DynamoDB integration
  • Processing DynamoDB stream events
  • Deploying serverless event-driven architectures

Example prompts

  • “Use the connecting-lambda-to-dynamodb skill to connect an AWS Lambda function to DynamoDB with IAM roles, stream event source mapping, and…”
  • “/connecting-lambda-to-dynamodb”

What it can do on your machine

Read from SKILL.md and the folder at commit bd49cc8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Connecting Lambda To Dynamodb loads about 341 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 128 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~341
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Connecting Lambda to DynamoDB

Overview

Domain expertise for connecting AWS Lambda functions to DynamoDB tables, including IAM execution role creation, function deployment, DynamoDB stream configuration, and event source mapping setup.

Connect a Lambda function to DynamoDB

To set up end-to-end Lambda-DynamoDB integration with IAM roles, streams, and event source mapping, follow the procedure exactly. See Lambda-DynamoDB connection procedure.

Troubleshooting

Lambda function not triggering

Verify the event source mapping is active, DynamoDB streams are enabled with the correct view type, and the execution role has proper permissions. See the full procedure for details.

Permission denied errors

Check the IAM role has AWSLambdaDynamoDBExecutionRole attached and the trust policy allows Lambda to assume it.

Function timeout issues

Increase the timeout setting or adjust the batch size in the event source mapping.
