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

Which US money market funds hold paper from a given issuer, from SEC Form N-MFP monthly portfolio filings — the reverse of a fund fact sheet, which makes you name the fund first. Give an issuer name (e.g. “Federal Home Loan Bank”, “JPMorgan”) or a CUSIP. Returns each fund holding it, the fund family, the security title, investment category and maturity dates. Answers “which money market funds are exposed to this issuer”, “who holds this bank’s commercial paper”.
