League Boss Assist works through an MCP connection in a compatible client. It can review the roster information you share.

Connect League Boss Assist

One endpoint for your client.

https://league-boss-assist-production.up.railway.app/mcp

Use this as the server URL when adding a custom MCP connection. It is not a web chat or an App Store install link.

  1. Add the connection in a client that supports remote MCP servers.
  2. Share a roster screenshot or paste your lineup. Include scoring settings and your league rules.
  3. Ask a specific question about your team. Review source coverage, assumptions, and freshness before acting.

Your leagues.
A connected browser.

Windowkeep is the separate browser service being built underneath connected League Boss accounts.

01 / YOUR ACCOUNT

Human sign-in.

The planned flow opens the real fantasy site so you can sign in and complete 2FA yourself. No passwords in chat.

02 / YOUR TEAM

A fresh roster read.

Yahoo, ESPN, and CBS are connection targets. The first live pilot will validate session reuse and roster inspection.

03 / YOUR CONTROL

Decisions before changes.

Lineup edits, waivers, trades, and recurring team management need separate validation before they can be offered.

Does League Boss need my Yahoo API access?

The connected-browser direction is designed around your signed-in website session, without depending on Yahoo API access. Real website compatibility still needs a live pilot.

Can it change my lineup today?

The available Assist service provides advisory analysis from the information you share. The public product does not currently execute lineup edits, waivers, or trades.

How are League Boss and Windowkeep different?

League Boss is the fantasy product: roster context, league rules, and decisions. Windowkeep is the general browser service: persistent workspaces, connection controls, and bounded agent tasks.
