AWS Simple Storage Service

Enable the AWS Simple Storage Service connector in your fastn dashboard, then let each customer authenticate their own AWS Simple Storage Service account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no AWS Simple Storage Service client code in your app and no per-customer branch in your codebase. Setup is 4 steps.

Yes. Every connection is scoped to the individual customer, so each authorises their own AWS Simple Storage Service account and only ever sees their own files, documents and versions. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.

Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reads an object to answer a question grounded in the customer's own files.

fastn does. When AWS Simple Storage Service changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.

Each customer's own AWS Simple Storage Service grant. Where AWS Simple Storage Service holds a library, their existing folder and item permissions apply and your product cannot reach content the connected account could not reach itself. Where it processes content you supply rather than storing it, the call runs under that customer's own credentials and is logged per tenant.

Where AWS Simple Storage Service supports writes, documents, entries and assets can be created, updated and filed from your product or by an agent within scoped permissions, with each action logged. Where it is a read surface, the same connection serves reads only.

A common starting point: read and write objects in their own buckets from your product. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding AWS Simple Storage Service does not change your per-connector cost. You can start free with 3 connected accounts.
