How to use Claude for fantasy football

To use Claude for fantasy football, add League Loom, a free, read-only connector, so Claude can read your ESPN, Sleeper or Fantrax NFL league.

Then run five prompts: rate my team, start/sit, waivers, a trade check and your matchup. Add it on a computer, then ask from Claude's phone app too; ChatGPT works on the web.

Who should I start at flex this week in my fantasy football league?

Your flex options for this week, ranked by projected upside:

1
Jaylen WarrenRB · PITrostered avail.
Soft run defense on the schedule and a rising snap share make him the steadiest floor of your bench options.
2
Jayden ReedWR · GBrostered avail.
Higher ceiling but boom-or-bust: target share has bounced around the last few weeks.
Start Warren at flex. He gives you the safer floor while Reed stays a risky upside play.

Five prompts for your football week

Start with rate my team

Ask Claude to read your roster, scoring and standings, then rate the team by position group and name your single biggest weakness. That one answer sets up every other question in the week.

Then the lineup call

Ask for a start/sit call on every slot you are unsure about, with the reason, and have it flag any slot already locked for this lineup period rather than suggesting a swap you cannot make.

Then waivers, with the drop

Ask for the best available players in that league, the drop each one would cost you, and your returned FAAB balance or waiver position. Confirm the claim deadline yourself; no provider returns it.

Check an offer when one arrives

Compare both rosters, the starting slots the trade would change and the depth left behind. Ask for an accept, pass or counter recommendation, with missing keeper rules or deadlines confirmed by you.

Then the matchup

Ask for your fantasy matchup and the score as of the returned snapshot. Separate live scores from projections, and identify unfinished starters only where game or lineup information supports it.

Worked example

Five decisions for your football week

Start with a team review, then copy the prompt for the decision you need. A trade check is useful when you have an offer to compare.

  1. Rate my team

    Ask for a position-by-position read with your biggest weakness named, and make Claude cite the roster and standings it actually read.

  2. Fix the weakness

    Take that weakness into the waiver ask: the best available player at that position, the drop, and what the claim would cost from your returned budget.

  3. Set the lineup

    Ask for a call on every uncertain slot with the reason, and leave any locked slot alone. Recheck before kickoff if a status came back questionable.

  4. Check a trade offer

    Compare the roster you have with the one the offer would leave you. Ask what would change the recommendation before you send or accept anything.

  5. Check the matchup

    Ask for a score snapshot and what remains unresolved. If player game status is missing, have the assistant say so instead of guessing who has yet to play.

Copy the prompt for your next decision

Paste one into your connected AI conversation. Each starts by checking the team and season.

1. Rate my team

Use League Loom to confirm my selected NFL team and season, then read my roster, scoring, starting slots and standings. If the team or season is unclear, ask me before advising. Review each position group, name my biggest roster weakness and explain it using the returned data. Separate facts from your judgment, flag missing fields and cite any outside research separately. Finish with one priority for this week. I will make any moves myself.

2. Make a start/sit call

Use League Loom to confirm my NFL team, season and lineup period. Read my roster, scoring, eligible slots and player lock states. Ask which decision I need if I have not named it. For each uncertain slot, compare eligible options and give a start/sit call with the reason. Keep locked slots unchanged; if a lock state is unknown, ask me to confirm it before suggesting a swap. Use projections only where returned, and cite current news or other research separately. Flag missing injury information. I will set the lineup myself.

3. Plan a waiver claim

Use League Loom to confirm my NFL team and season, then read my roster, scoring and available-player pool. Suggest up to three available adds with a possible drop, the roster need each fills and the trade-off. Use remaining FAAB or waiver priority only where returned; do not treat a season budget as my remaining balance. Respect roster locks and ask me to confirm unknown eligibility and the claim deadline. Flag missing data and cite outside news separately. Return a short add/drop table. I will submit any claims myself.

4. Check a trade offer

Use League Loom to confirm my NFL team and season. Ask me for the offer if I have not supplied it, then read both teams' rosters, our scoring, roster slots and standings. Compare the starting lineup and bench depth I would have before and after the trade. Give an accept, pass or counter recommendation with the reason and what would change it. Separate returned stats from forecasts and outside research. Ask for missing keeper costs, contract rules or the trade deadline instead of inventing them. I will send or accept any trade myself.

5. Check my matchup

Use League Loom to confirm my NFL team, season and current scoring period, then read my fantasy matchup. Show the fantasy opponent, score and snapshot time where returned. Keep projected, live and final scores separate. Identify starters who have yet to play only when game or lineup information supports it; otherwise say that their status is unknown. Do not infer game timing from injury status. Flag missing fields, and cite any real-world schedule research separately. Explain what remains uncertain. Treat this as a snapshot when I ask, not a continuous update or alert.

FAQ

Questions

How do I set up Claude for fantasy football?

Add the League Loom connector to Claude, sign in to your fantasy provider once, and pick your NFL team. After that you can ask Claude about your roster, matchups, waivers, and standings in plain language. Setup usually takes a couple of minutes and needs no API keys.

Does this work with my fantasy football league?

Yes, if your league is on ESPN, Sleeper, or Fantrax. All three cover NFL, so League Loom can read your football league and answer questions about it through Claude. It also handles other sports those providers support.

Is it safe to connect my league to Claude, and does it cost anything?

Yes. League Loom is a free independent MCP connector, not an official Claude or league plugin. Your credentials stay sealed inside your encrypted connection (with an optional encrypted email recovery backup).

What can Claude tell me about my fantasy football team?

Claude can walk through your roster, weekly matchups, standings, draft results, and available or waiver players, and it can pull season fantasy points and ownership for context. If you have more than one league, it can aggregate across all of them at once.

How do I get Claude to rate my team?

Ask it to read your roster, scoring and standings first, then rate the team by position group and name your single biggest weakness, citing the roster and standings it read. Take that weakness straight into the waiver ask so the rating turns into a move you can actually make.

Where do I find more prompts?

The full library of weekly prompts, including the waiver report, lineup check and trade finder, lives on the prompts page. This page is the football walkthrough; the cross-sport overview of what Claude can read sits on the Claude fantasy sports page.

Can I set League Loom up on my phone?

Add the connector on a computer: claude.ai or Claude Desktop, or ChatGPT on the web. What works on a phone afterward depends on the assistant. In Claude, a connector added on the web or desktop is also available in the Claude iOS and Android apps, so you can ask about your leagues from your phone. In ChatGPT, custom apps like League Loom currently run only on the web, not in the ChatGPT phone apps. If you start on a phone, use Send to my computer to email or message yourself the link and finish later.
