Supplier Invoice Tool
Turns a UK trade business's supplier invoices (CEF, Edmundson, Screwfix, Toolstation and others) into one draft Xero bill per supplier per month, one line per job, with the originals kept and price rises flagged.
Endpoint: https://supplier-invoice-tool.nerolabs.workers.dev/mcp (MCP, Streamable HTTP)
Sign-in: A private key per business. The first call (create_trade_account) returns it once; every later call sends it as the header "Authorization: Bearer ". Xero is connected separately by the business signing in to Xero.
Status: Test mode. Free while it is tested. Only a Xero Demo Company can be connected until the Xero link is approved.
