Cursor With Wasabi MCP

Wasabi MCP is an OAuth-protected Model Context Protocol (MCP) server that lets an AI client operate your Wasabi account (S3, IAM/STS, WACM) without ever receiving your Wasabi access keys. The client gets a short-lived, scoped OAuth token; your Wasabi credentials stay encrypted on the server.

Wasabi’s MCP service is currently in beta and may be subject to changes, limitations, or occasional instability. Report any issues you encounter to Wasabi Support (support@wasabi.com).
