Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-19 (score 55, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `convert_bank_statement` (~322 tokens)

Convert bank statement

Convert one PDF bank statement through the complete MainBook workflow: create a job, upload, start, poll, and return structured data. This creates a job and spends page credits; it is not read-only.

Input parameters:

- `file_path`: Path to a PDF on the MCP server machine. This field is only available over stdio and is rejected in HTTP mode; remote clients must use file_url. The path must be inside the allowed folders, which def…
- `file_url`: Public HTTPS URL of a PDF for remote mode. Redirects and non-public network addresses are rejected. Exactly one source is required.
- `idempotency_key`: Optional value forwarded verbatim in the Idempotency-Key REST header.
- `output_path`: Optional absolute result file or existing folder on the MCP server machine. Only available over stdio and only inside the allowed folders. The file extension is corrected to match result_type.
- `result_type` (string): JSON is returned inline. Over stdio, XLSX or CSV is written to an allowed local folder and the full path is returned. HTTP mode returns safe download instructions. Binary bytes never enter model cont…
- `timeout_seconds` (integer): Internal polling budget from 30 to 900 seconds. Timeout leaves the job running and returns its job_id for get_conversion. The default stays under the 60-second request timeout most MCP clients enforc…

Output parameters:

- `data`
- `download`
- `job_id` (string)
- `message` (string)
- `pages`
- `result_type` (string)
- `saved_file`
- `state`
- `timed_out` (boolean)
- `validation`

### `get_balance` (~27 tokens)

Get page-credit balance

Return total, reserved, and available MainBook credits. Every value is measured in PDF pages.

Output parameters:

- `available` (integer)
- `balance` (integer)
- `explanation` (string)
- `reserved` (integer)
- `units` (string)

### `list_conversions` (~62 tokens)

List conversions

List one cursor page of conversion jobs visible to the MainBook account. Pass the returned next_cursor to continue.

Input parameters:

- `cursor`: Opaque next_cursor from the previous page.
- `limit` (integer): Jobs on this page, from 1 to 100.

Output parameters:

- `conversions` (array)
- `count` (integer)
- `next_cursor`
- `units` (string)

### `get_conversion` (~112 tokens)

Get conversion

Get the current state of one MainBook conversion. When successful, return JSON inline or save XLSX/CSV locally over stdio. HTTP mode returns safe download instructions. Use this after convert_bank_statement times out.

Input parameters:

- `job_id` (string, required): Conversion job UUID returned by MainBook.
- `output_path`: Optional absolute result file or existing folder on the MCP server machine. Only available over stdio and only inside the allowed folders.
- `result_type` (string): Result representation to retrieve after the job succeeds.

Output parameters:

- `data`
- `download`
- `job_id` (string)
- `message` (string)
- `pages`
- `result_type` (string)
- `saved_file`
- `state`
- `timed_out` (boolean)
- `validation`

### `output_folder` (~75 tokens)

Manage output folder

Read or change the default local result folder. Call with no path to inspect the current setting and allowed folders. Pass an allowed absolute folder, or 'next_to_source' to restore the default behavior.

Input parameters:

- `path`: Allowed absolute folder to remember, or 'next_to_source' to reset. Omit to read without changing anything.

Output parameters:

- `allowed_folders` (array)
- `message` (string)
- `output_folder` (string)
