Terms.
Plain English: Muffed is free, read-only, and tells you about football. It doesn't tell you what to do about it.
What Muffed is
A free NFL statistics and story service. It publishes verified figures, reference pages, and AI-written podcasts about every team and a library of players. Everything is read-only: nothing you do here writes to anything but your own Muffed account.
No account is required for the reference layer — the stat boards, glossary, handcuff pages and trends — or for the MCP server at https://muffed.ai/api/mcp, which lets an AI assistant call the same verified figures directly. An account is only needed for the personalized weekly show built around your own roster.
No advice
Muffed publishes verified figures and editorial context. It publishes no projections, no start/sit or lineup advice, no draft grades, no rankings offered as advice, no picks, and no betting lines or odds. Nothing on this site or in the MCP server is a recommendation to take any action of any kind, and you are responsible for your own decisions.
This is a permanent product position, not a limitation we intend to remove. Where a question calls for a recommendation, Muffed returns verified context instead — including any “smashed” or “muffed” verdict in an episode, which is a description of what happened and not a suggestion about what to do next.
Muffed takes no payments, sells nothing, and facilitates no transaction, wager or transfer of anything of value.
Where the data comes from
Figures are derived from nflverse, NFL Next Gen Stats via nflverse, and FTN Data via nflverse, used under Creative Commons attribution licences. The credit line is part of the licence, so it is carried on every surface — on the page, and verbatim on every MCP tool response: Data via nflverse · NFL Next Gen Stats via nflverse · FTN Data via nflverse. Charting-derived figures cover the 2025 season only and say so wherever they appear.
Sleeper league data comes from Sleeper's public read-only API. It is read only when you ask for it, it is never written to our database, and it is never linked to you.
Muffed is not affiliated with, endorsed by, or sponsored by the NFL, the NFLPA, any NFL club, any player, Sleeper, or any data provider. Team names, logos, and player names are referenced for editorial purposes; all trademarks belong to their respective owners.
Accuracy, and its limits
Figures published on the reference layer and served by the MCP server are verified against a gated panel at publication and carry an as-of date. Muffed's verification covers those figures as returned. Analysis built on top of them by a third party — an AI assistant combining several responses, a ratio or a ranking derived from them — is that party's own work and is not covered by Muffed's verification or its attribution.
The podcast episodes are AI-written. The data underneath is real, but the narrative may occasionally get a stat wrong, miss a play, or describe something that didn't happen quite that way. Listen for the story; if a specific number matters to you, check the figure on the stat board it came from.
The service is provided “as-is”, without warranty of any kind. To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of it.
Acceptable use of the site and the MCP server
Use it freely as an individual. Please don't bulk-scrape it, don't redistribute the underlying datasets as a competing data feed, and don't try to work around the rate limits — they exist so one caller can't take the server down for everyone else. Rate limits may change without notice.
If you are calling the server at volume or building it into a product, email hello@muffed.ai first so we can keep it up for everyone. The underlying nflverse data is openly licensed and free to anyone — what Muffed adds is verification, structure, freshness, and the story layer.
We may change or stop the service
Muffed is a small, free product. We may pause it, change it, or shut it down at any time without notice. If we do, we will do our best to give you an honest heads-up.
Governing law
These terms are governed by the laws of the State of California.
