The weekly walkthrough, prompt by prompt
Once League Loom is connected, five prompts cover a football week in ChatGPT: rate my team, the start/sit call for every uncertain slot, the waiver claim with its drop, a trade check and the matchup.
Each one answers from your live ESPN, Sleeper or Fantrax NFL roster instead of a generic ranking.
Connect your leaguesStep 1: In ChatGPT, add League Loom as a connector and sign in. It is free, and takes about a minute.
Step 2: Pick your ESPN, Sleeper, or Fantrax league. Now just ask ChatGPT about your team in plain English.
Reading your connected ESPN roster and this week's matchups to rank your RB options.
| Start | Sit | |
|---|---|---|
| RB1 | James Cook | None |
| RB2 | Chase Brown | None |
| Flex | None | Tyjae Spears |
Checking your roster gaps against available players in your connected league.
Illustrative example, not a live league report. Your answer depends on your league data and AI tool.
2 minutes
In Claude, ChatGPT, or any MCP tool, add a custom connector, give it a name, and paste the League Loom URL as the server address.
Load your leagues in the setup wizard. Select a personal team for team-specific help, or leave it unselected for league overviews. No API keys.
Ask about your roster, waivers, matchups, and more, in plain language, across every league.
Adding a connector is a job for a computer. Send yourself the link and finish there.
https://leagueloom.com/mcpYour tool asks for a name and this URL. Then connect your leagues in the setup wizard. Personal team selection is optional.
Ask ChatGPT 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.
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.
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.
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.
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
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.
Ask for a position-by-position read with your biggest weakness named, and make ChatGPT cite the roster and standings it actually read.
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.
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.
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.
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.
Paste one into your connected AI conversation. Each starts by checking the team and season.
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.
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.
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.
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.
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.

Why League Loom
Without a league connection, ChatGPT is guessing. It does not know your roster, scoring, bench, or waiver pool, and pasted data goes stale as soon as the league changes.
Add League Loom as a custom connector, authorize it, and choose your team in the setup wizard. ChatGPT can then use live rosters, standings, matchups, available players, scoring rules, waiver settings, and Sleeper FAAB details.
Ask who to start at flex, which receivers are trending on your waiver wire, or how your playoff format works; no write-action tools are registered today.
FAQ
Not on its own. Add League Loom's MCP connector at leagueloom.com/mcp and ChatGPT can read your live league data to answer roster questions.
Add the connector URL https://leagueloom.com/mcp in ChatGPT, then link your ESPN, Sleeper, or Fantrax league. Credentials stay sealed in your own encrypted connection.
Yes. The League Loom connector is free.
Once connected, ChatGPT surfaces injury and bye-week status on your best-available list and when it checks your lineup, pulled from your league data. It won't pull outside news or beat-reporter updates, so treat it as a roster-level check, not a full injury report.
Yes, once League Loom is connected it can read your league's real settings, scoring format, lineup slots, waiver or FAAB system, and playoff structure, and explain them in plain language instead of guessing at generic defaults.
Current connector tools recommend waiver and start/sit decisions; no write-action tools are registered today.
Ask it to read your roster, scoring and standings first, then rate the team by position group and name your single biggest weakness, citing what it read. Take that weakness straight into the waiver ask so the rating becomes a move you can actually make.
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 ChatGPT can read sits on the ChatGPT fantasy sports page.
Setting up is easier on a computer, because that is where the connector settings in Claude and ChatGPT are designed to be used. You can still start from a phone browser by opening those settings from our home page, and if you would rather finish later, use Send to my computer to email or message yourself the link. Once the connector is added, asking questions works fine from your phone.
