MCPBundles Vault

File storage built into your workspace. Files are stored in AWS S3 (eu-west-2), encrypted at rest by AWS SSE-S3.

Data Model

  • Files — blobs in S3, metadata in workspace DB. Scoped to workspace via RLS.
  • Folders — nested containers for organization (workspace root by default).
  • Categories — general, identity, financial, legal, medical, digital.

Auth

No credentials required. Vault is a first-party MCPBundles service — enable the bundle and it works.

Usage

  • Upload — save text or binary content as a file
  • Download — retrieve file content (text as UTF-8, binary as base64)
  • Browse — list files with optional folder or category filters
  • Search — find files by name
  • Metadata — read file metadata without downloading bytes
  • Delete — permanently remove a file
  • Folders — create nested folders for organization
  • Usage — workspace storage consumption stats

Limits

  • Max file size: 100 MB per file.
  • Files over 50 MB return metadata only on download.
