Hosted MCP server for Xero
Xero is where hardware spend becomes real: supplier bills, payments, and the accounts your finance team reconciles at month end. On its own it knows nothing about parts or revisions — which is exactly why connecting it to the rest of your stack through bomrail is so useful. The purchase order in your factory system and the bill in Xero describe the same event, but no human wants to cross-reference them line by line.
The bomrail hosted MCP server for Xero gives agents read access to bills, payments, purchase order documents, and contacts, scoped through Xero’s own OAuth consent. Ask which bills are unpaid, which supplier invoices do not match a received PO, or how much you have spent with a machine shop this quarter — and get answers grounded in the ledger, not a stale export.
bomrail treats Xero as a strictly-audited read source by default. Write actions (creating a bill, updating a reference) exist behind per-action human approval on the Growth plan, so an agent can draft but never silently post to your books.
What the Xero MCP server exposes
Typed, read-only tools over bills, payments, purchase orders, contacts/suppliers, account summaries — callable by Claude, Claude Code, or any MCP-compatible agent:
bomrail.get_bill_status (po | bill_id) Bill status for a PO or bill: amount, due date, paid/unpaid.
bomrail.list_unpaid_bills (supplier?) Outstanding bills, optionally filtered by supplier.
bomrail.get_supplier_spend (supplier, period) Total spend with a supplier over a period, itemized by bill.
bomrail.find_bill_mismatches (po_ids) Bills whose amounts or quantities differ from the referenced purchase orders.
Questions teams ask
- Which Apex Machining bills are unpaid and past due?
- How much did we spend on fasteners suppliers last quarter?
- Do any bills disagree with their PO amounts this month?
Why not just use the Xero API directly?
You can — and for a single scripted workflow you should. bomrail earns its keep where direct API access gets expensive: distributing and rotating credentials across a team, keeping tools current as the Xero API evolves, and producing the audit trail your quality system expects when an AI is doing the reading. One OAuth sign-in, one MCP URL for the whole team, every call logged. Read more on the security page, or see what an MCP server is if the concept is new.
