Best pick, every round

AI Fantasy Draft Assistant

League Loom is a free connector that reads your ESPN, Sleeper or Fantrax league settings and draft results, so Claude or ChatGPT can weigh the best available pick for your roster while you are on the clock.

It is not a mock draft simulator, and you make every pick. The same connection covers football, basketball, hockey and baseball; Sleeper covers NFL and NBA only.

My basketball draft is Saturday. What does my league actually reward?

Your league returned a categories scoring type, and your four keepers came back with salaries. The category list, lineup slots and salary cap were not returned. Here is what is settled and what is not:

How to connect

1

Add the connector

In Claude or any MCP tool, add a custom connector; in ChatGPT on the web, turn on developer mode and use the + button on the Plugins page. Give it a name and paste https://leagueloom.com/mcp as the server address. Setup is easiest on a computer; once it is added, you can ask from Claude's phone app during the draft. ChatGPT runs custom apps on the web only.

2

Connect the league you are drafting

Sleeper needs your username only. A public ESPN league needs nothing, and a private one takes your own espn_s2 and SWID cookies. Fantrax takes the league URL from your address bar.

3

Open a Draft Kit

Copy the Draft Kit prompt for your platform from the prompt library, paste it into your AI, and answer the handful of questions it asks about your draft slot, budget, or keepers.

https://leagueloom.com/mcp

Open setup wizard →

Your tool asks for a name and this URL. Then connect your leagues in the setup wizard. Personal team selection is optional.

What changes by platform

Basketball and hockey are the live draft season

NBA and NHL drafts run through September and October. League Loom reads ESPN, Sleeper and Fantrax basketball leagues and ESPN and Fantrax hockey leagues, including scoring settings and Fantrax salaries, so a category build or a cap budget starts from your league rather than a generic ranking.

ESPN returns the most settings

Full scoring, lineup slots, ESPN's own projections, ADP and average auction values come through the connector, so the assistant can show where the app's default ranks misprice a player for your rules. Private leagues need your own espn_s2 and SWID.

Sleeper is built for dynasty

A username is the whole setup. Your roster, scoring, the league's draft picks and platform-wide trending adds come back, which is what a rookie-only draft actually turns on. Keeper costs are not exposed, so the assistant asks.

Worked example

Work one pick end to end

A repeatable sequence, not a recorded live draft.

  1. Confirm the league

    Ask for your connected setup and your league's scoring and roster slots. Check the sport and season before any ranking talk.

  2. Read the board

    Ask which players are already drafted and what your roster is short of. Missing draft data must stay missing rather than becoming an empty board.

  3. Separate league facts from research

    Ask the assistant to label every projection or ADP figure as league data or outside research, and to say which public source it used.

  4. Decide, then pick

    Ask what would change the recommendation, then make the pick yourself in ESPN, Sleeper, or Fantrax. No League Loom tool submits a pick.

Try this after connecting

Read my connected league's scoring, roster slots, and draft results. Tell me what my roster is short of, then name the best available players for that need. Label every projection or ADP number as league data or your own research, and list anything you could not retrieve. Do not submit a pick.

Fantasy football

A free AI draft assistant for fantasy football

League Loom is free, with fair-use request budgets, and connects ESPN, Sleeper and Fantrax football leagues to Claude, ChatGPT or another MCP client. Your AI tool may have its own plan requirements.

Before the draft, the assistant reads the scoring and roster slots your platform returns and asks for what no connector returns, like your draft slot and keeper costs. During the draft it reads completed picks, so you can ask who is still available at a position and have a pick graded against your league's rules.

Scoring first

PPR, half PPR, TE premium and superflex change who belongs in each round. The assistant should restate your scoring from the returned settings before it ranks anyone.

Completed picks

Draft results return round, pick, team and player on ESPN, Sleeper and Fantrax, plus auction bids on ESPN and Fantrax, so the board reflects the picks already made when you ask.

Research, labeled

ESPN returns its own projections and ADP, and Fantrax returns ADP. Projections for Sleeper and Fantrax leagues, and any outside rankings, come from public sources the assistant researches and should label next to each number.

Illustrative example with fictional players. It shows the shape of an answer, not a current ranking or a recorded draft.

You askI pick next in round 5 of a half PPR league. Who should I take?

Example answer

Your league returned half PPR scoring with one QB, two RB, three WR, one TE and one flex. You have drafted two running backs, one receiver and one quarterback.

Your biggest gap is receiver: three WR slots and one filled. Receiver A and Receiver B are still available with ESPN ADP in this round, and Tight End C is the best left at a thinner position.

Take Receiver A. If both receivers go before your pick, Tight End C is the fallback. The ADP is ESPN's; the target shares are outside research.

Plan my next pick

Use League Loom to confirm my NFL league, season and team, then read the scoring settings, roster slots and the draft results so far. Ask me for my draft slot or remaining auction budget if they were not returned. List my drafted players by position and the starting slots still empty. Suggest up to five targets for my next pick from players still available, with the reason for each, and label every projection or ADP figure as league data or your own research. Say what would change the order. I will make the pick myself.

What it will not do

  • Run a mock draft or predict other managers' picks.
  • Submit, queue or trade a pick. You draft in your fantasy app.
  • Know your draft slot, auction budget or keeper costs unless they are returned or you supply them.

ESPN drafts

ESPN fantasy draft help with AI

ESPN returns more draft-day data through League Loom than the other platforms: full scoring settings, lineup slots, ESPN's own projections, ADP and average auction values in player lookups, and draft results with auction bids and keeper flags. That lets the assistant compare ESPN's default ranks with your actual scoring and point out where they disagree. A public league loads by URL; a private league also needs your espn_s2 and SWID cookies.

Your scoring against ESPN's ranks

The ESPN draft room ranks players for default settings. Ask the assistant to re-rank a position for your scoring and show which players move most.

Auction values

ESPN player lookups can include average auction values next to ADP, which helps set a maximum bid before a player is nominated.

Every ESPN sport

The same connection reads ESPN football, basketball, hockey, baseball and WNBA leagues.

Illustrative example with fictional players. It shows the shape of an answer, not a current ranking or a recorded draft.

You askMy ESPN league gives tight ends 1.5 points per catch. Who is ESPN underrating?

Example answer

Your scoring returned 1.5 points per reception for tight ends and 1 for everyone else.

Re-ranked for that rule, Tight End A moves from an ESPN ADP of 60 to about 38 on this board, and Tight End B from 95 to about 70. Receivers with similar catch totals move less, since they earn 1 point per catch.

Tight End A is the value if he is there in round 4. The catch projections are ESPN's; the re-rank is my own calculation from your scoring.

Compare ESPN's ranks with my scoring

Use League Loom to confirm my ESPN league, sport, season and team, then read the full scoring settings, lineup slots and any draft results so far. Look up ESPN's projections, ADP and average auction values for the players I name, or for the top available players at the position I ask about. Re-rank them for my league's scoring and show where the order differs from ESPN's ADP, labeling any outside projections as research. Ask me for my draft slot or budget if it was not returned. I will make my own picks.

Before you rely on it

  • Private-league cookies expire. Refresh espn_s2 and SWID if the league stops loading.
  • ESPN projections are ESPN's forecasts, not a forecast League Loom makes.
  • No tool submits a pick or a bid.

Sleeper drafts

Sleeper mock drafts, rookie drafts and what the AI can read

League Loom is not a mock draft simulator, and it does not read Sleeper mock draft rooms. What it reads is your real Sleeper league: scoring settings, roster slots, every team's roster, the league's draft picks once they are made and platform-wide trending adds, all from your username with no password.

That makes it most useful for a dynasty rookie draft or a redraft you are preparing for, and for checking the board once your draft is under way. Sleeper covers NFL and NBA leagues.

Rookie drafts

In a dynasty league the assistant reads your roster and every other team's, including player ages, so it can say which positions you are thin at before a rookie-only draft.

Rehearse without a simulator

To practice, ask the assistant to walk through your first rounds from your slot, stating its assumptions about other managers. It is a thought exercise, not a simulation of your league.

No draft rankings from Sleeper

Sleeper does not return season projections or ADP, so draft rankings come from research the assistant should label.

Illustrative example with fictional players and picks. It shows the shape of an answer, not a prospect ranking or a recorded draft.

You askMy Sleeper rookie draft is next week and I have picks 1.04 and 2.09. What should I target?

Example answer

Your roster came back with four running backs, two of them over 28, and six receivers. Two other teams in your league are also thin at running back.

At 1.04, research the top running back prospects first. At 2.09, a receiver or tight end with a clear role is the better use of the pick.

Your pick numbers and the prospect notes come from you and outside research, not from Sleeper. Ask again once picks are made and I can read who is gone.

Prepare for my Sleeper rookie draft

Use League Loom to confirm my Sleeper league, season and team, then read the scoring settings, roster slots, every team's roster and any draft picks already made. If the league or season is unclear, ask me before advising. Tell me which positions my roster is thinnest at for the next two seasons and which other teams need the same positions. Then ask me for my pick numbers, and list the rookies to research at each pick, labeling all rankings and prospect notes as outside research. I will make my own picks in Sleeper.

What it cannot do

  • Run or read a mock draft.
  • Read the rookie draft order or a full list of traded picks before picks are made.
  • Make a pick. You draft in Sleeper.

NBA and NHL

Basketball and hockey drafts

The same draft workflow covers NBA and NHL leagues. Basketball drafts run on ESPN, Sleeper and Fantrax; hockey drafts on ESPN and Fantrax, since Sleeper hockey is not supported.

Most leagues in both sports draft in the weeks before the regular season. Category leagues need the most care: per-player stat categories come back only where your provider or public research returns them.

Basketball

Points or categories, guard and big-man depth, and Fantrax salaries in cap leagues. The basketball guide has a live draft board prompt and an ESPN basketball check.

Hockey

Goalie slots and minimums, skater positions and ratio categories. The hockey guide covers when to take a goalie and what the data cannot confirm about starts.

Check these elsewhere

  • Category projections and punt plans, which are not supplied.
  • Confirmed goalie starts, NBA minutes and real game schedules.

Why League Loom

Best pick, every round

Static cheat sheets and preseason rankings go stale the moment your draft starts moving in directions nobody predicted. League Loom instead reads your actual league, so the assistant knows your scoring, your roster construction and which players are already gone.

That means Claude or ChatGPT can reason about your specific team, not a generic strategy. The platform you play on changes what the assistant starts from.

ESPN returns full scoring settings, lineup slots, its own projections, ADP and average auction values, so the assistant can re-rank the board for a TE premium or a category league and show where ESPN's defaults misprice somebody. Sleeper needs only a username, and what it returns (your roster, your scoring, the league's draft picks and platform-wide trending adds) is what a dynasty rookie draft turns on.

Fantrax carries a salary on every rostered player and returns average draft position in its available-player data, which makes auction and cap planning possible. Projections are the honest boundary.

Sleeper and Fantrax do not return league-scored season projections, so the assistant researches those and tells you when a number came from its research rather than your league. It will also ask for what no connector can see, like your draft slot, auction budget and keeper costs. League Loom does not run mock drafts, and no tool submits a pick.

FAQ

Questions

Does it see who's already been drafted?

Yes. League Loom reads your draft results, so the AI knows which players are gone and recommends the best available for your roster needs.

Does it use my league's actual scoring?

Yes, and this is the whole point. ESPN exposes full scoring settings and lineup slots, Sleeper returns its scoring settings, and Fantrax returns league info and roster rules. The assistant re-ranks players for the league you are actually in rather than a default list, which matters most in a TE premium, a category basketball league, or any format that is not standard.

Does it help with fantasy basketball drafts?

Yes. League Loom reads ESPN, Sleeper and Fantrax NBA leagues, so the assistant can plan a category build from the settings your provider returns, or a salary-cap budget from Fantrax salaries plus the cap and roster rules you supply. Per-player category stats come back only where the provider or public research returns them.

Does it work for dynasty and rookie drafts?

Yes, and Sleeper is where most of them live. League Loom reads your existing roster and the league's draft picks once they are made, so the assistant can tell you which positions are actually thin heading into a rookie-only draft instead of ranking players in a vacuum.

Does it work for auction drafts, not just snake drafts?

Yes. Fantrax returns a salary on every rostered player and average draft position in its available-player data, and ESPN player lookups can include average auction values, so the assistant can weigh remaining budget against player cost. For a Sleeper auction, tell it your budget when it asks and it plans a spend allocation across your roster spots instead of a round by round order.

Where do the projections come from?

Two places, and the assistant labels both. ESPN's own projections, ADP and auction values come through League Loom, and Fantrax returns ADP. Everything else, including Sleeper rankings and outside projections, is researched by the assistant from public fantasy sources and identified as research rather than league data.

Is it a mock draft simulator?

No. League Loom does not run mock drafts, simulate other managers or read mock draft rooms. It reads your real league's settings, roster slots and draft results, so it is most useful for preparing for the draft you will actually have and for checking the board once picks are made.

Is the AI draft assistant free?

League Loom is free, with no subscription or per-league fee, and fair-use request budgets apply. You can connect up to 25 leagues per platform. Your AI tool has its own plan and connector requirements, so check those before draft day.

What do I need to connect for each platform?

Sleeper needs only your username, because its league data is public. A public ESPN league needs nothing; a private one needs your own espn_s2 and SWID cookies, sealed into your encrypted connection. Fantrax takes your league URL, because account discovery by Secret ID often returns nothing.

Can it make my picks for me?

No. No League Loom tool can submit a pick. You draft in your fantasy app while the assistant advises.

Can it help me during a live draft, or only before it starts?

Both. Before your draft, ask it about your league's rules, scoring, and roster needs. Once the draft is under way it reads completed picks, so you can ask who is best available or get a pick graded round by round.

Is League Loom free?

Yes. The MCP server and connector are free, with no subscription and no per-league fee. Fair-use request budgets apply. Connect supported ESPN, Sleeper, and Fantrax leagues and ask questions from your AI tool.
