MLB Data

Before writing queries, consult references/api-reference.md for endpoints, ID conventions, and data shapes.

Setup

Before first use, check if the CLI is available:

which sports-skills || pip install sports-skills

If pip install fails with a Python version error, the package requires Python 3.10+. Find a compatible Python:

python3 --version  # check version
# If < 3.10, try: python3.12 -m pip install sports-skills
# On macOS with Homebrew: /opt/homebrew/bin/python3.12 -m pip install sports-skills

No API keys required.

Quick Start

Prefer the CLI — it avoids Python import path issues:

sports-skills mlb get_scoreboard
sports-skills mlb get_standings --season=2025
sports-skills mlb get_teams

CRITICAL: Before Any Query

CRITICAL: Before calling any data endpoint, verify:

• Season year is derived from the system prompt's currentDate — never hardcoded.
• If only a team name is provided, call get_teams to resolve the team ID before using team-specific commands.

Choosing the Season

Derive the active season from the system prompt's date — not just the calendar year.

• If the user specifies a season, use it as-is.
• If the user says "current", "this season", or doesn't specify: The MLB season runs late March/April through October. If the current month is January–March, the last completed season was the prior calendar year. From April onward, use the current calendar year.

Commands that DO NOT exist — never call these

• get_odds / get_betting_odds — not available. For prediction market odds, use the polymarket or kalshi skill.
• search_teams — does not exist. Use get_teams instead.
• get_box_score — does not exist. Use get_game_summary instead.
• get_player_ratings — does not exist. Use get_player_stats instead.

If a command is not listed in the Commands table above, it does not exist.

Error Handling

When a command fails, do not surface raw errors to the user. Instead:

1. Catch silently and try alternatives
2. If team name given instead of ID, use get_teams to find the ID first
3. Only report failure with a clean message after exhausting alternatives

Troubleshooting

Error: sports-skills command not found Cause: Package not installed Solution: Run pip install sports-skills

Error: Team not found by ID Cause: Wrong or outdated ESPN team ID used Solution: Call get_teams to get the current list of all 30 MLB teams with their IDs

Error: No data returned for a future game Cause: ESPN only returns data for completed or in-progress games Solution: Use get_schedule to see upcoming game details; get_scoreboard only covers active/recent games

Error: Offseason — scoreboard returns 0 events Cause: No games scheduled during the offseason (November–March) Solution: Use get_standings or get_news instead; MLB offseason transactions are available via get_transactions
