# Link in Seconds documentation

Guides for sharing files as links, plus the API and MCP server for developers and AI agents.

Link in Seconds turns any file into a clean public link that opens in any browser, with no account, app or download for the person you send it to. These docs cover everything from your first upload to publishing files from your own code or an AI assistant.

[Share your first file Upload, copy the link, send it. Under a minute.](https://linkinseconds.com/docs/quickstart)[Control who sees it Passwords, expiry dates, view-only and view limits.](https://linkinseconds.com/docs/link-settings)[Upload with the API Three HTTP calls from file to public link.](https://linkinseconds.com/docs/api/uploads)[Connect an AI assistant Let Claude, Cursor or VS Code publish files for you.](https://linkinseconds.com/docs/mcp)

## For AI assistants, in one line

Add our MCP server to Claude Code with your API key, then ask it to “publish this page as a link”. Other clients are covered in [MCP server](https://linkinseconds.com/docs/mcp).

Shell

```
claude mcp add --transport http linkinseconds https://linkinseconds.com/api/mcp \
  --header "Authorization: Bearer lis_YOUR_KEY"
```
