SST Python SDK

The Python SDK for SST lets you access linked resources in your Python Lambda functions.

Installation

pip install sst-sdk

Or with uv:

uv add sst-sdk

Migrating from the Git dependency

If you were previously installing the SDK from GitHub:

# Before
[project]
dependencies = ["sst"]

[tool.uv.sources]
sst = { git = "https://github.com/anomalyco/sst", subdirectory = "sdk/python" }

Update your pyproject.toml to use the PyPI package instead:

# After
[project]
dependencies = ["sst-sdk"]

That's it — remove the [tool.uv.sources] entry for sst and replace the dependency name. No code changes needed; from sst import Resource works the same way.

Usage

Use Resource to access any resource linked to your function in sst.config.ts:

from sst import Resource

# Access linked resources by name
bucket_name = Resource.MyBucket.name
table_name = Resource.MyTable.name

Resources are defined and linked in your sst.config.ts:

const bucket = new sst.aws.Bucket("MyBucket");

new sst.aws.Function("MyFunction", {
  handler: "handler.main",
  link: [bucket],
});

The SDK reads resource bindings from encrypted environment variables set by SST at deploy time. In sst dev, resources are available automatically through the local development bridge.
