Announcing the Check MCP Server

We're releasing two new ways for AI agents to interact with our platform:

• The Check MCP server, which enables AI assistants like Claude, Codex, and Gemini to use Check's payroll APIs through the Model Context Protocol.
• The Check CLI, a command-line interface that allows developers and AI agents to manage payroll operations programmatically from the terminal.

Both of these beta tools can be cloned from our public GitHub repository and used today with any Check platform API key.

Both beta tools ship with full support for over 260 API operations, including list, filter, retrieve, create, update, and delete (where applicable) across all Check API objects. The MCP and CLI also support fine-grained tool filtering, configurable via environment variables or HTTP headers, as well as the ability to run in read-only mode.

These tools can be used to pull custom reports, load historical data into Check’s system for companies that are switching from a prior payroll provider, answer support questions about topics from tax applicability to employee and tax payment timing, and more.

For more information on how to get this set up, please see our API docs.
