NBA draft prep, rosters, and league reports
League Loom connects your ESPN, Sleeper, and Fantrax NBA leagues to ChatGPT or Claude for fantasy basketball questions.
Prepare for your draft, review your team, or follow a whole league without selecting a personal team.
Connect your leaguesStart with the connected league season and scoring format, then review guards, forwards, and centers. Keep last season's performance separate from current roster information.
| Check | What to establish |
|---|---|
| Roster depth | Positions held and open spots |
| Keeper costs | Returned salaries plus any rules you supply |
| Draft research | Current roles and news from separate sources |
For an identified team, the report brings together returned standings, matchups, roster status flags, and recent activity. Unavailable sections are labeled rather than filled with guesses.
A flagged starting guard can prompt a check of bench guards and available guards. Position matches are candidates to investigate, not confirmed legal replacements or category projections.
A personal team is optional. The report uses a league overview when no team is identified, with returned standings, matchup summaries, and recent moves.
| Connection | Report scope |
|---|---|
| One league | That league's overview |
| Several leagues | Name one league or request all |
| Mixed team selections | Team reports where identified; overviews elsewhere |
Illustrative example, not a live league report. Your answer depends on your league data and AI tool.

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.
Choose your provider from ESPN, Sleeper, or Fantrax, then load your NBA league. Verify the displayed sport and season, especially after a league renews. Follow the provider guide below for access requirements.
Start with points versus category scoring, then confirm lineup rules. A player who fits a points roster may not fit a punt strategy. Exact category arithmetic needs complete per-player stats, and returned stat coverage varies by provider.
Review depth across guards, forwards, and centers. Use returned draft history or salary fields where available, and supply missing keeper costs and rules. Treat prior-season totals as historical context.
Ask for roster checks, returned matchup information, recent moves, and available-player candidates. The weekly digest samples candidates by position need and provider order; it is not a complete player ranking or projection model.
Name one league for a focused report, or ask for all connected leagues. If no personal team is identified, you get league overviews. Mixed connections can show team reports and league overviews together.
Per-player stat categories are returned only where a provider or public player research exposes them. ESPN player lookups can include season actual and projected values for up to five players per call, keyed by ESPN stat IDs rather than category names. Fantrax available-player data in viewable leagues can include the league's stat columns, but rostered Fantrax players come back without them. Check returned values against your platform before exact category math. Matchup reads summarize team scores rather than a category-by-category breakdown. Category matchup forecasts, full NBA game schedules, usage, and confirmed rest decisions are not supplied. Verify those separately before recommending a punt build or a schedule-based stream. Sleeper and Fantrax do not supply league-scored NBA projections, and Sleeper does not supply ownership percentages.
Worked example
Illustrative workflow. Player availability, roster slots, and rules depend on your connected league.
Suppose a starting guard carries an injury flag. Read the returned status and check your bench before searching the available-player pool.
A bench guard or available guard may cover the position, but verify slot eligibility and current injury news. A category-league decision also needs each player's category stats, which vary by provider; a points-league decision needs the applicable scoring and available projections.
Compare the likely benefit with the player you would drop and any returned FAAB or waiver priority. State missing evidence and assumptions, then make any move yourself on the provider.
Paste one into your connected AI conversation. Each starts by checking the team and season.
Review my connected basketball leagues and confirm their seasons and scoring formats. For each identified team, summarize roster needs and draft or weekly priorities. Otherwise give a league overview. Separate returned facts, missing data, and outside research before suggesting any action.
Use League Loom to confirm my NBA league, season and whether it uses points or categories, then read the league settings, roster slots and any returned draft or keeper data. If the league or season is unclear, ask me before advising. Explain how this format changes the value of guards, forwards and centers, and list the positions to prioritize. Use per-player stat categories only where returned, and do not invent category projections or build a punt strategy from missing stats. Treat last season's totals as history and cite current news or rankings separately. I will make my own picks.
Use League Loom to confirm my NBA team and season, then read my roster and any returned salary, contract or keeper fields. If the team or season is unclear, ask me before advising. List which fields came back and which rules I still need to supply, such as keeper limits, cap, contract years or deadlines. Rank my keeper candidates using only returned data plus the rules I give you, and label outside research separately. I will submit any keeper decisions myself.
Use League Loom to confirm my NBA 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. Use stat categories and minutes only where returned. Full NBA game schedules are not returned, so cite schedule research separately before recommending a stream. Respect roster locks and ask me to confirm unknown eligibility. Return a short add/drop table. I will submit any claims myself.

Why League Loom
Fantasy basketball advice starts with the league you actually play in. League Loom supplies the roster, standings, settings, and player information your provider returns; the assistant interprets it.
In the preseason, use that context to identify roster gaps and research questions. During the season, ask for a weekly report with source limitations kept visible.
A fantasy matchup schedule describes teams in your fantasy league, not the real-world NBA schedule. Outside news and game schedules should be checked separately and labeled as outside research. Every move remains yours to make on your fantasy platform.
FAQ
League Loom connects ESPN, Sleeper, and Fantrax NBA leagues. ESPN also supports WNBA, and Fantrax supports college basketball. This guide focuses on NBA workflows. Check the capability matrix for differences in returned data.
Yes, you can connect supported leagues and ask the assistant to use their scoring format and available rules. Per-player stat categories are returned only where a provider or public player research exposes them, such as ESPN player lookups and Fantrax available-player lookups, and labels and coverage vary. Matchup reads summarize team scores rather than a category-by-category breakdown, and category matchup forecasts are not supplied, so the assistant should not invent category projections or build a punt strategy from missing stats. Missing scoring rules should be supplied before giving format-specific advice.
Yes. Start with returned rosters, league settings, and draft data where available. Supply keeper eligibility, costs, deadlines, or contract terms that are missing. Last season's totals are historical context, not a current forecast; research role changes and injuries separately.
No. If no personal team is identified, the weekly digest provides a league overview of returned standings, matchups, and recent activity. Identify a team only when you want personal roster checks and team-specific recommendations.
Connect them once, then name a league for a focused report or request all connected leagues. Each entry keeps its provider, league, team context, and data limitations. A connection can include both personal teams and leagues followed without a team selection.
