`manager_portfolio`

Pack: sec-13f · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

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

Every 13F position reported by one institutional manager, largest first — the classic manager-first view, over the same indexed data. Give the manager name (“Berkshire Hathaway”, “Pershing Square”). Returns each holding with value and share count, plus the reported quarter. For what CHANGED since the prior quarter use manager_changes instead.

Parameters

Name	Type	Required	Description
`manager`	string	yes	Filing manager name or a distinctive fragment of it.
`limit`	number	no	How many positions to return, 1-200 (default 50).
