Scriptable Compliance Checks

This isn't for manual one-offs. Use this MCP from any shell script. Pipe in your layoff data and call `check_warn_compliance` to get a simple, script-friendly exit code. Zero for compliant, non-zero for a violation. It’s designed for automation. You can build a simple bash script that reads from a CSV of proposed layoffs and checks each one, logging any potential violations to a file without any manual intervention.

Get Total Liability via CLI

When a check fails, get the financial impact instantly. Chain commands to pipe the event data into `calculate_employee_backpay_liability` and `calculate_civil_penalty_exposure`. The output is clean, parsable JSON. You can use tools like `jq` to extract the exact numbers you need. This lets you automatically populate environment variables for the next stage of your pipeline or send a structured alert with the full cost breakdown.

Run Audits in Your CI Pipeline

Add this MCP Server to your CI/CD environment, like GitHub Actions. Create a job that runs on a schedule or when your HRIS data changes. Let it check for any new, large-scale layoff events that might trigger the WARN Act. A failed pipeline job is a much better alert than a letter from the Department of Labor. This setup gives you a continuous, automated guardrail against costly compliance mistakes.

Common questions about US WARN Act Compliance Calculator MCP in Claude Code

Connect Claude Code to the MCP. In your pipeline script, like in a GitHub Action, call the tools with your layoff data. You can fail the build if `check_warn_compliance` returns a violation.

Use it for automation. Write a shell script that pulls data from a source, uses Claude Code to run the calculations, and then pipes the JSON output to `jq` for parsing or to another script for alerting.

Absolutely. Set up a cron job that executes a script. The script can use Claude Code to run a full liability analysis via this MCP and email the results to your legal and HR teams every week.

No. It's a calculation engine that models financial risk under the WARN Act. It provides data for your decisions, but does not replace the judgment of qualified legal counsel.

The service is stateless. It only processes aggregate data like employee headcounts and dates for a specific event. No personally identifiable information is ever sent or stored. Your connection via Claude Code is transport-layer encrypted.
