propline-mcp
Listed in the official MCP Registry as io.github.proplineapi/propline-mcp — discoverable from Claude Code, Claude Desktop, and any MCP-aware client.
Model Context Protocol server for the PropLine player props betting odds API. Plug it into Claude Desktop, Claude Code, or any MCP-compatible client and ask natural-language questions about live odds, prop resolution, cross-book +EV, scores, and box-score stats — the model picks the right tool, calls the API, and answers from real data.
No more "I'd need an API for that" deflections from your AI assistant. PropLine MCP turns sports-betting research into a chat.
What you can ask
Once installed, you can prompt the model with things like:
- "What's the +EV on Yankees vs Red Sox tonight across all books?"
- "Pull Aaron Judge's last 20 prop-bet history with hit/miss outcomes."
- "List today's MLB pitcher strikeout props from DraftKings and Pinnacle side by side."
- "Did Nikola Jokic's points prop hit last night? What was the line?"
- "Compare PrizePicks DFS projections to Bovada lines for tonight's NBA slate."
The model uses these tools transparently:
| Tool | What it does |
|---|---|
propline_list_sports | Discover what sports PropLine polls (24 today) |
propline_list_events | Upcoming events for a sport, with ids |
propline_list_event_markets | Available market types for an event |
propline_get_odds | Live odds — bulk by sport or full props per event |
propline_get_odds_history | Pro: full snapshot history per outcome |
propline_get_scores | Game scores + status (free) |
propline_get_resolution_summary | Graded-prop volume + per-sport/market breakdown (free) |
propline_get_event_stats | Raw box-score stats (free, book-agnostic) |
propline_get_event_results | Pro: graded won/lost/push per prop |
propline_get_player_history | Player prop history with resolution |
propline_get_event_ev | Pro: cross-book +EV with no-vig fair lines |

Comparison with the-odds-api
PropLine is API-compatible at the response level (same bookmakers[].markets[].outcomes[] shape) and adds three things the-odds-api doesn't offer at any tier:
- Prop resolution — every Over/Under graded against the actual box-score stat after the game
- Cross-book +EV — Pinnacle-anchored no-vig fair lines per book, sorted with +EV plays at the top
- Webhooks — push delivery on Streaming tier, not pull-only
Pricing: free at 1,000 req/day (vs their 500/month), Pro at $19/mo for 25,000 req/day, Streaming at $79/mo for 1,000,000 req/day. No credit math.
