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.
  • Creates signing flows with a receiver phone number.
  • Queries signing flow details by flow ID.

Use cases of Esign MCP

  • Automate contract signing from local documents (Word, PDF, images, etc.).
  • Integrate e签宝 signing into AI‑powered workflows via MCP.
  • Monitor and verify the progress of signing processes programmatically.
  • Replace manual file conversion and upload steps in document signing pipelines.

常见问题

1

What file formats are supported?

Supported formats include PDF, Word (docx, doc, rtf), Excel (xlsx, xls), PowerPoint (pptx, ppt), WPS files (wps, et, dps), images (jpeg, jpg, png, bmp, tiff, tif, gif), and HTML (html, htm). All are automatically converted to PDF.

2

Are there any file size or name restrictions?

Yes. Total file size must not exceed 50MB and a single page must be under 20MB. File names cannot contain special characters (`/ \ : * " < > | ?`) or emoji, and the extension must match the actual file format.

3

What environments are available?

The `HOST` variable accepts three values: test environment (for development), sandbox environment, and production environment (`https://openapi.esign.cn`).

4

How does error handling work?

The tool automatically catches common errors (unsupported format, upload failure, conversion failure, flow creation failure), logs them to `/tmp/app.log`, and returns a detailed error message to the user.

5

What license does this server use?

Esign MCP is distributed under the MIT license.
