Dropbox Connector

Dropbox connector for file search, metadata, and approval-gated temporary links.

Credential setup

bearer

Use an app token limited to files.metadata.read; temporary links also require files.content.read.

Setup docs: https://www.dropbox.com/developers/apps

After adding this connector, attach the credential on the server page, then run astrail tools list.

Hosted MCP endpoint

/api/mcp/preset-dropbox

Private servers require an Astrail API key in the Authorization header.
