File Relay

A remote MCP connector that lets AI agents hand you the files they create. The agent saves the file locally, uploads it with curl, and you get an expiring download link. Agents need a shell with internet access (Claude Code, Codex, Cursor; on claude.ai, allow code.easyllms.com in the code execution network settings). Links expire after 24 hours by default (7 days at most), and files are permanently deleted from storage within 7 days of upload. Each file can be up to 100 MB.

Connect

MCP server URL (Streamable HTTP, no sign-in):

https://code.easyllms.com/relay/mcp

• Claude (claude.ai / Desktop): Settings → Connectors → Add custom connector → paste the URL.
• ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app → paste the URL, authentication “No authentication”.
• Claude Code: claude mcp add --transport http file-relay https://code.easyllms.com/relay/mcp
• Codex CLI: in ~/.codex/config.toml add [mcp_servers.file-relay] with url = "https://code.easyllms.com/relay/mcp"
• Cursor and others: {"mcpServers":{"file-relay":{"url":"https://code.easyllms.com/relay/mcp"}}}

Tools

• create_upload_link: the agent saves the file locally, gets a one-time upload URL and uploads it with curl (up to 100 MB) → download link
• relay_attached_file: ChatGPT file references → download link
• get_file_info / read_file: let another agent pick a file up
• delete_file: delete a file early with its delete token

Anyone with a link can download the file until it expires, so do not relay secrets.

中文说明：给 AI Agent 用的临时文件中转。Agent 先把文件存到本地，再用 curl 传上来，你拿到一个会过期的下载链接（Agent 需要能执行命令并联网；claude.ai 要在代码执行的网络设置里放行 code.easyllms.com）（链接默认 24 小时后失效，最长 7 天，文件上传 7 天内从存储中彻底删除，单文件不超过 100 MB）。在 Claude / ChatGPT 里添加自定义连接器，填上面的 MCP 地址即可。
