Definition
N-MFP versus N-PORT
are both SEC portfolio holdings reports. N-MFP is filed monthly by money market funds. N-PORT is filed quarterly by other registered management funds, such as open-end and closed-end funds and ETFs. One is money-market and monthly; the other is broader and quarterly. Source: SEC.
Who files each, and what does it report?
Form N-MFP is filed by a money market fund about the fund and its portfolio holdings for the preceding month. Each fund or series files a separate form, under Rule 30b1-7 of the Investment Company Act. Form N-PORT is the machine-readable portfolio holdings report for other registered management investment companies, filed quarterly. Both are structured data feeds of what a fund holds; the split is the type of fund and how often it reports.
How do they differ?
The differences come down to which fund files, and how often.

Which one should you read?
Read whichever matches the fund. For a money market fund's holdings, open the N-MFP. For another registered fund's holdings, use the N-PORT. For a fund's certified shareholder report and financials, that is the N-CSR, and for how a fund is organized and serviced, the N-CEN annual census. For a manager-level snapshot of large US equity positions, see the 13F.
Both N-MFP and N-PORT sit on the SEC's EDGAR system, free to read. Flock reads disclosure filings and keeps each one dated and linked to its source, so you can move from a summary to the original filing in one step. What any of it means for your money is your call to make.
