No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/sec_13d_filing for the schema, then POST the same URL with its arguments for the data.

Parse one 13D/13G filing: reporting owners, voting power, percent of class, Item 4 purpose.

Tool description as the model sees it

Parse ONE Schedule 13D or 13G filing by issuer + accession_number (get the accession_number from sec_13d_filings). Returns every reporting owner (the “group members”) with percent of class, sole/shared voting power, sole/shared dispositive power, and aggregate shares owned; for Schedule 13D, also Item 4 — the free-text “Purpose of Transaction”, which is where an activist states its intent (board seats, a merger, liquidation, or “no plans”). Filings from before SEC’s 2024 structured-XML rule have no machine-readable fields — this returns structured: false plus the bounded plain text of the filing instead of silently returning empty data.

Parameters

Name	Type	Required	Description
`ticker_or_cik`	string	no	Ticker, company name, or CIK of the ISSUER the filing is about (same value you passed to sec_13d_filings).
`ticker`	string	no	Alias for ticker_or_cik.
`cik`	string	no	Alias for ticker_or_cik.
`accession_number`	string	yes	The filing’s SEC accession number, e.g. “0001104659-25-086308” (dashes optional). From sec_13d_filings.
