Connect it
The server speaks JSON-RPC 2.0 over HTTP POST. No API key, no OAuth — add the endpoint and it works.

What it exposes
| Tool | What it does |
|---|---|
| vigil_describe_inputs | Explains which Xero exports the check can read (Trial Balance, Account Transactions, Aged Receivables / Payables) and how to obtain them — so the assistant knows what to ask for. |
| vigil_run_health_check | Takes the exports as CSV text plus an optional industry, runs the diagnostic, and returns the score, headline verdict, and each finding with the reasoning for why it matters. |
One file is enough for a result; more files unlock more checks. Formats are auto-detected — exports do not need cleaning first.
What it will never do
- It is read-only, permanently. There is no tool that posts journals, changes records, or connects to any accounting system. It analyses text the user chooses to provide — nothing else.
- It stores no financial data. File contents are processed in memory for the duration of the request and discarded. The only thing ever persisted is an email address, and only if the user volunteers one to be contacted.
- It returns the diagnosis, not the treatment. The free check shows what is wrong and why it matters. The specific corrections, their order, and a scope to put things right are professional work — see below.
Who is behind it
The Vigil Health Check is built and operated as part of Vigil Ledger, the continuous compliance-monitoring platform for accountants, and is provided by Insight Professional Partners Ltd, a UK practice led by a CIMA Member in Practice. If the check surfaces problems in your books and you want them put right by a qualified accountant, that is exactly what the practice does.
