Extra care is performed to strip out sensitive data and ensure we're not sharing too much.n* The Update Employee too also guards against updating fields which would preferably remain readonly. When you control the MCP server, you can determine behaviour of the tool.n* Finally, a Google Sheet node is used to log all operations for later audit. This will add a tiny bit of latency but recommended if sensitive data is being accessed.nn### How to usen* This MCP server allows any compatible MCP client to manage their PayCaptain employee database. You will need to have a PayCaptain account and developer key to use it.n* Connect your MCP client by following the n8n guidelines here - https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-langchain.mcptrigger/#integrating-with-claude-desktopn* Try the following queries in your MCP client:n * "When did Sarah start here employment at the company?"n * "Does Jack work Wednesdays or Fridays?"n * "Please update Tracy's NI number to ABCD123456"nn### Requirementsn* PayCaptain Account and Developer Key.n* Google Sheets to log actions for later audit.n* MCP Client or Agent for usage such as Claude Desktop - https://claude.ai/downloadnn### Customising this workflown* Add or remove employee attributes as required for your user case.n* If Google Sheets is too slow, consider an API call to a faster service to log calls to the MCP server.n* Remember to set the MCP server to require credentials before going to production and sharing this MCP server with others!"
