MCP

518.PLUS runs a standard MCP server (Streamable HTTP). Configure it once in any MCP client and your agent can call every 518 file tool — metered per call, failed calls refunded.

Quick start

Create an API token first: Tokens（fsk_ 开头）
Add the server URL + Bearer token in your MCP client
Ask your agent to process files right in the conversation

HTTP API (Bearer)

Need plain REST? API v1 stays available under the same Bearer token.
