Trigger Contracts from Your CI/CD Pipeline

Embed contract generation directly into your development workflow. You can create a GitHub Action that, on a new release tag, runs a Claude Code script to `create_sign_flow` for a new Service Level Agreement. The script can then use `add_docs` and `start_flow` to automatically send it to the customer. The output of one command, like the new `flowId`, can be piped to the next step in your pipeline. This is headless automation for your legal processes, managed entirely from the terminal.

Run Bulk Signing Operations with Shell Scripts

Onboarding a new batch of employees? Don't send contracts one by one. Write a simple shell script that reads a CSV of new hires, then loops through it, using Claude Code to call the eSign (e签宝) tools for each person. Your script can call `create_sign_flow` using a standard employment contract template, `add_signers` with the new hire's details from the CSV, and `start_flow` to send it. This is how you automate HR and legal tasks at scale. This MCP Server makes it possible.

Monitor and Archive Contracts with Cron

Keep your systems in sync without manual checks. Set up a cron job that runs a Claude Code script every night. The script can use `list_sign_flows` to find all completed contracts from that day, then call `download_docs` to archive the signed PDFs to a secure backup location. You can also build alerting with it. Have your script check for flows that have been pending for more than 7 days and pipe the details to a monitoring service or a Slack webhook. It's a powerful way to manage contract health from the command line.

Common questions about eSign (e签宝) MCP in Claude Code

You run a single command in your terminal: `claude mcp add ...` with the server URL provided by Vinkius. Once connected, the eSign (e签宝) tools are available directly for use in your shell scripts and CI/CD jobs.

Absolutely. Claude Code is a headless CLI, so it's perfect for containerized environments. You can build a Docker image with your script and run it as part of a larger, automated workflow to `create_sign_flow` and manage contracts.

Each tool call returns a standard exit code. A successful call returns 0, while an error returns a non-zero code. You can use standard shell scripting logic (`if [ $? -ne 0 ]`) to check for failures and handle them, like retrying a `start_flow` call.

Yes. The `list_sign_flows` tool is designed for this. You can run `claude esign-e-mcp list_sign_flows` and pipe the JSON output to tools like `jq` to filter, sort, or transform the data right in your terminal.

Your Vinkius token authenticates you with the MCP Server, which then uses securely stored credentials to talk to eSign (e签宝). Document data like PDFs and signer information is streamed through an encrypted, in-memory-only process and is never written to disk on the server.
