Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Turn on guest uploading for a gallery and get the link to share.

SmugMug MCP tools: https://cotlet.dev/docs/mcp/smugmug.md

MCP tool: `smugmug_write → set_guest_upload_key`

Access: write. Confirm: waits for the user's OK before it runs.

Sets the Guest Uploading field under Security & Sharing and returns the upload link. Anyone with the link can upload into this gallery and only this gallery. Guests still need the viewing password for a password gallery, and an invitation for a People I Choose gallery, to see photos. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `gallery_id` | string | yes | Gallery ID from list_galleries. |
| `key` | string | yes | Letters and digits only. Guests can see it in the link. An empty value removes the key. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
