Sling a file

For AI agents

Your agent built it. Now you review it.

Connect Claude, Cursor, ChatGPT or any MCP client. When your agent makes something (a landing page, a logo, a song, a deck) it sends it to you on Slingdrop. You comment on the exact spot and approve or ask for changes, and it comes back with the next version.

  • I built the pricing page. Sent v1 for your review.

The loop

Feedback your agent can actually use

No more pasting screenshots back into a chat. Comments arrive with their location in words, like “pinned on the headline” or “at 1:42”, so the agent knows exactly what to fix.

  1. 1. Agent sends

    request_review uploads the work and gives you a link. You get a notification.

  2. 2. You comment

    Open it on any device. Pin comments, highlight, or comment at a timestamp.

  3. 3. You decide

    Approve, or request changes with a note. The agent is waiting for it.

  4. 4. Agent revises

    submit_revision sends v2 behind the same link and resolves what it fixed.

Works with everything an agent makes

Review anything, in the browser

Web pages and designs

Landing pages, components and prototypes render live and interactive in the review, at desktop, tablet and phone sizes.

Images and logos

Pin comments on the exact pixel. Compare versions side by side.

Songs, voiceovers and video

Comment at 1:42, or on a range. The agent gets the timestamp.

Documents and slides

PDFs, Word, PowerPoint and spreadsheets preview in the browser, with highlights and page pins.

Code and copy

Comment on a line or a sentence. The agent sees the quote.

Anything else

Every file type can be shared, versioned and approved.

Connect your agent

The remote server at https://slingdrop.my/mcp signs you in with your Slingdrop account. Or run it locally with an API key from Settings → Developer, which also lets your agent send local files and folders by path.

Claude Code

terminal
claude mcp add --transport http slingdrop https://slingdrop.my/mcp

Or locally, with a key:

terminal
claude mcp add slingdrop --env SLINGDROP_API_KEY=sd_… -- npx -y @slingdrop/mcp

Claude.ai and ChatGPT

Add a custom connector with this URL, then sign in to Slingdrop when asked:

https://slingdrop.my/mcp

In Claude: Settings → Connectors → Add custom connector. In ChatGPT: Settings → Connectors → Create (developer mode).

Cursor, Windsurf and other clients

mcp.json (remote)
{
  "mcpServers": {
    "slingdrop": { "url": "https://slingdrop.my/mcp" }
  }
}

Claude Desktop and any stdio client

claude_desktop_config.json
{
  "mcpServers": {
    "slingdrop": {
      "command": "npx",
      "args": ["-y", "@slingdrop/mcp"],
      "env": { "SLINGDROP_API_KEY": "sd_…" }
    }
  }
}

Signing in creates an API key named after the app, which you can revoke any time in Settings → Developer. Agents can only do what the tools allow, and every review link is yours.
