概要

What is Esign MCP?

Esign MCP is a Model Context Protocol server that integrates with the e签宝 (eSign) electronic signing platform, enabling file upload, signing flow creation, and signing status queries via standardized MCP tools.

How to use Esign MCP?

Configure the server by setting the environment variables HOST, APP_ID, and APP_SECRET in your MCP client’s configuration, then run npx -y mcp-server-esign@{version}. Two tools are available: create_sign_flow (upload a local file and initiate a signing flow) and query_sign_flow (check the status of a flow by its ID).

Key features of Esign MCP

Supports multiple file formats auto‑converted to PDF.
Automatically checks file processing status.
Logs all operations to /tmp/app.log.
