Model Context Protocol server for the PropLine player props betting odds API. Exposes live odds, prop resolution, cross-book +EV, scores, and box-score stats as tool calls for Claude Desktop, Claude Code, and any MCP-compatible client.
PropLine MCP demonstrates solid tool design with 22 well-named, read-only tools covering sports betting data. All tools have descriptions (avg 150 chars) and explicit JSON schemas with typed parameters. Naming follows verb_noun convention (get_, list_, propline_ prefix). However, several tools lack output schema documentation, parameter descriptions are sometimes generic, and error handling guidance is minimal. No tool annotations (readOnlyHint/destructiveHint) despite clear risk profiles. One WRITE tool (propline_create_free_api_key) lacks confirmation pattern.
Register a free PropLine API key for an email address. The key is emailed to that address and never returned here — the response is only a status message. Use this to help users get their own key (removes pooling, unlocks full free tier).
Export full line-movement tick history as CSV. Backfill pass / Enterprise only — other tiers get a 403. Returns raw CSV text; the tool caps row count so a large pull never floods the context. A time window (since/until) is required to bound the download.
Fetch DFS (daily fantasy sports) payout odds from PrizePicks and other platforms. Returns expected value and payout structure for slate contests.
Fetch contextual information for an event (injuries, weather, recent form, etc.). Helps explain why props are moving or why certain outcomes are more likely.
Fetch cross-book +EV (expected value) opportunities for an event. Returns lines where one book's odds are better than the consensus, with the EV% calculated against the sharpest available price. Optionally filter by min_ev_pct to show only plays above a threshold.
No output schemas documented for any tool. LLMs cannot plan downstream calls or extract fields without knowing response structure.
propline_create_free_api_key (WRITE tool) lacks confirmation/dry-run pattern. Agents could accidentally register multiple keys without user consent.
No tool annotations (readOnlyHint/destructiveHint/idempotentHint) despite clear risk profiles. 21 tools are READ_ONLY, 1 is WRITE, annotations would guide agent safety.
Parameter descriptions for optional filters (markets, bookmakers, period) are minimal. LLMs need guidance on when to use these filters and valid format.

Fetch recent line movement for an event. Shows which direction odds have moved and by how much, useful for identifying sharp action and consensus shifts.
Fetch prop resolution results for a completed event. Returns which props won/lost/pushed and the final settled odds. Use this to understand how your bets resolved.
Fetch box-score stats for a completed event. Returns per-player and team statistics (points, rebounds, assists, etc. depending on sport). Useful for post-game analysis and understanding prop outcomes.
Fetch futures odds for a sport (e.g. season MVP, championship winner). Returns long-term bets with current odds across books.
Fetch MLB Grand Salami odds (total runs across all games on a date). Returns the current line and movement.
Fetch NHL daily goals total (total goals across all games on a date). Returns the current line and movement.
Fetch live odds for a sport or event. Optionally filter by market (e.g. player_points), bookmaker (e.g. draftkings, fanduel), or event. Returns each line's current odds across all configured sportsbooks.
Fetch closing odds (the final line before the event started) for an event. Useful for CLV (Closing Line Value) analysis and understanding the market's final assessment.
Fetch historical odds movements for an event. Returns snapshots of each line's odds over time, useful for line-shopping analysis and understanding how sharp money moved the market.
Fetch historical stats for a player across multiple events. Returns per-game performance (points, rebounds, assists, etc.) useful for trend analysis and prop evaluation.
Fetch a summary of recently resolved props across all sports. Shows which props won/lost/pushed and by how much, useful for understanding market accuracy and finding patterns.
Fetch live and final scores for a sport. Returns each event's current or final score, status, and timestamps. Useful for understanding game context when analyzing props.
Grade placed bets against their closing lines (CLV). Returns win/loss/push status and CLV% for each bet. Hobby+ tier. Useful for evaluating bet quality and line-shopping skill.
List all markets available for an event (e.g. player_points, player_rebounds, team_total_points). Use the returned market keys with propline_get_odds to fetch lines.
List upcoming events for a sport. Returns each event's id, home_team, away_team, commence_time. Use the returned event_id to drill into per-event odds, props, +EV, or results.
List all sports PropLine currently polls. Returns sport keys (e.g. baseball_mlb, basketball_nba, soccer_epl) along with human titles and active status. Use this first to discover what sport_key values are valid for the other tools.
Price a same-game parlay (SGP) at a book's correlated odds. Returns the parlay's fair odds and payout. Hobby+ tier. Currently supports FanDuel.
No error handling guidance in tool descriptions. LLMs cannot determine if a 403 (tier restriction) is retryable, user-fixable, or fatal.
