Is the Amazon S3 MCP server free?

Yes. Activepieces is open source and free to start, and the MCP server is included on every plan, from the free cloud tier to any self-hosted deployment.

How do I connect Amazon S3 to Claude or Cursor?

Connect Amazon S3 in Activepieces, enable the server under Settings → MCP Server, then paste your server URL into your client config. It authenticates over OAuth on first use.

What can my agent do in Amazon S3?

It can call 8 tools, including Upload File, Read File, Generate signed URL, and chain them with steps in other apps inside the same run.

Is it safe to let an agent call Amazon S3?

Connections use OAuth2 with limited scopes and are stored under 256-bit encryption, with no API to read them back, so an agent gets scoped access rather than your keys.
