No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/pcaob_auditor_changes for the schema, then POST the same URL with its arguments for the data.

Issuers whose most recent Form AP filing names a DIFFERENT audit firm than their prior filing, where the new filing landed in the last N days — the “who switched auditors recently” aggregation, which no upstream PCAOB page offers directly. Scans issuers with a Form AP filing in the window (capped at 1500 issuers per call) and compares each against its own filing history.

Parameters

Name	Type	Required	Description
`days`	number	no	Lookback window in days for the most recent filing (default 90).
`limit`	number	no	Max changes to return, 1-200 (default 50).
