How is the RSA signature handled?

Rong360 APIs typically require generating a strict base64 signature for each URL. This MCP server entirely abstracts that operation. You just securely paste your pkcs8 Private Key once during setup, and the agentic execution environment automatically handles URL signing on each outgoing LLM request.
