NBA Prop Lab

PropLab MCP Server

Model Context Protocol server for PropLab: NBA and WNBA player-prop analytics. You get the daily board the model publishes before tip-off, its public record graded against the official box score, defense vs position, usage, referees and player research.

There are two ways to use it:

• Remote server: works now, nothing to install, no key. https://nbaproplab.com/mcp
• Local stdio package, built from this repository. It adds backtests and on-demand pick evaluation, which need an API key. It is not yet published on npm.

The data is informational sports analysis, not betting advice. PropLab does not take wagers, link to sportsbooks or guarantee outcomes, and past results do not predict future ones.

Remote server (recommended)

Streamable HTTP, stateless, no authentication. Every tool is read-only and returns the same public data shown on nbaproplab.com.

Claude (claude.ai, desktop, mobile): Settings → Connectors → Add custom connector. Name: PropLab. URL: https://nbaproplab.com/mcp. Authentication: none.

Claude Code:

claude mcp add --transport http proplab https://nbaproplab.com/mcp

Codex:

codex mcp add proplab --url https://nbaproplab.com/mcp

or in ~/.codex/config.toml:

[mcp_servers.proplab]
url = "https://nbaproplab.com/mcp"

Any other client that supports streamable HTTP can point at the same URL.

Tools

Tool	Parameters	Returns
daily_board	league (nba or wnba)	The published player-prop board for the next slate (player, stat, line, direction, tier, model score) and how the previous board settled
track_record	league?, tier? (Premium or Standard), from?, to?	Settled record by tier and stat. The published record is the Premium tier (premiumHitRate, goodPicks) and Standard (marginalPicks); overall* fields also count internal ratings that are never published. Dates before 2026-04-03 are a backtest
defense_vs_position	league	Points, rebounds and assists each team allows to guards, forwards and centers relative to the league average, with defensive rating, pace and ranks
usage_leaders	league	Players ranked by usage rate this season, with last-10-games usage, minutes and points
nba_today	—	Today's NBA games with tip-off times, yesterday's scores and the standings
games	date? (yyyy-MM-dd)	NBA and WNBA games on a date (default: today, US Eastern)
referee_assignments_today	—	The crew of each NBA game today, once the league publishes it the morning of game day
referees	—	NBA referees this season with games worked and fouls per game against the league average
search_players	query	NBA and WNBA players by name, accents optional ("Jokic" finds Jokić)
player_research	playerId	Recent game logs, current prop lines across books with hit rates, injury status, next-game context and the model's picks on that player

Example prompts:

• "Which NBA teams allow the most rebounds to centers, and do any of them play today?"
• "How has PropLab's published Premium tier done in the WNBA since April, by stat?"
• "Search for Jokic and show his last 10 games and injury status."

Invalid arguments, for example league: "nfl", return a tool error that explains the valid values.

Local stdio package

Not yet published on npm, so build it from this repository:

git clone https://github.com/Khavel/proplab-mcp.git
cd proplab-mcp
npm install
npm run build      # compiles src/index.ts → dist/index.js

Then register it in your MCP client with the absolute path to the build:

{
  "mcpServers": {
    "proplab": {
      "command": "node",
      "args": ["/absolute/path/to/proplab-mcp/dist/index.js"],
      "env": {
        "PROPLAB_API_KEY": "…"
      }
    }
  }
}

PROPLAB_API_KEY is optional: without it the public tools still work. For local development with hot reload, run npm run dev.

Environment variables

Variable	Required for	Description
PROPLAB_API_URL	No	API base URL (default: https://nbaproplab.com)
PROPLAB_API_KEY	Backtest, pick and research tools	Bearer API key

The key is minted at nbaproplab.com → Account → API keys. It is shown once at creation and can be revoked from the same screen.

Verify locally

npx @modelcontextprotocol/inspector node dist/index.js

Then call proplab_system_status, which needs no key and should return the live system status.

Data and privacy

• Remote server: it keeps no state and stores nothing from your conversations. It only receives the arguments of each tool call (a league, a date, a player name or id), and the web server keeps its standard access logs.
• Local package: it calls the public nbaproplab.com API over HTTPS and reads the key only from the environment, never logging it. No tool reads database credentials or app settings, or opens a shell.
• Inputs are validated with zod and responses are truncated at 40,000 characters. Every tool is read-only except proplab_evaluate_pick, which scores a hypothetical pick and stores nothing.
• Privacy policy: nbaproplab.com/legal/privacy. Responsible gambling: nbaproplab.com/responsible-gambling.
