Use GSD-first tools for standings, structure, stats, actions, lineups, odds, rosters, and profiles. Use this family when the workflow fits this source-ownership boundary. Move to the tool page once you know the exact job and scope. ## Sequencing habits * Prefer atomic tools before reaching for a bundle. * Stay in GSD-first flows when the question is about standings, stats, lineups, odds, or structure. ##

Tool-by-tool guidance ### [`get_event_summary`](/sports-mcp-server/tool-reference/get_event_summary) * Job: Return the minimum single-event sports-truth object needed to answer what the event is and what is happening in it at summary depth. * Source ownership: GSD Lookup primary, On sports-event lookup optional when the caller already has On refs * Use it when: Use it as the default entry point for one known event before fetching deeper sections. * Do not use it when: the host needs play-by-play, lineups, stats, odds, or watchability detail in one response. ### [`get_event_lineups`](/sports-mcp-server/tool-reference/get_event_lineups) * Job: Return lineups and officials for one event. * Source ownership: GSD Lookup * Use it when: the answer needs the people on the field, court, grid, or match sheet. * Do not use it when: Do not use it as a general event summary or a substitute for stats or actions. ### [`get_event_timeline`](/sports-mcp-server/tool-reference/get_event_timeline) * Job: Return the action stream or timeline for one event. * Source ownership: GSD Lookup * Use it when: the product needs scoring actions, incidents, laps, plays, or turning points. * Do not use it when: Do not use it for lineups, aggregate stats, or watchability. ### [`get_event_stats`](/sports-mcp-server/tool-reference/get_event_stats) * Job: Return raw event stats plus normalized team and person stat groups with canonical metric keys. * Source ownership: GSD Lookup * Use it when: the answer needs performance numbers rather than a summary or timeline. * Do not use it when: the question is just about availability or schedule position. ### [`get_phase_results`](/sports-mcp-server/tool-reference/get_phase_results) * Job: Return ordered phase or session results for qualifying, rounds, heats, groups, and similar staged competition slices. * Source ownership: GSD Lookup * Use it when: the host already knows the right `phaseId` and needs the ordered result rows for that stage or session. * Do not use it when: Do not use it as a replacement for the full schedule, standings, or one-event summary. ### [`get_odds`](/sports-mcp-server/tool-reference/get_odds) * Job: Return event odds when available. * Source ownership: GSD Lookup * Use it when: the product explicitly needs odds or betting-style implied probability context. * Do not use it when: Do not use it for non-odds sports workflows or as a fallback when odds are missing. ### [`get_standings`](/sports-mcp-server/tool-reference/get_standings) * Job: Return raw standings plus normalized table rows and group metadata for a competition or competition season. * Source ownership: GSD Lookup * Use it when: Use it for table, ladder, playoff-picture, and current-rank questions. * Do not use it when: Do not use it for watchability, event detail, or generic ranking flows that are classification-based instead of table-based. ### [`get_rankings`](/sports-mcp-server/tool-reference/get_rankings) * Job: Return the richest non-empty leaderboard rows for a competition or series scope, plus selection metadata. * Source ownership: GSD Lookup * Use it when: the host needs leaderboards, driver standings, golf leaderboards, or category rankings rather than a single standings table. * Do not use it when: Do not use it to replace standings, one-event stats, or phase/session results. ### [`get_participant_profile`](/sports-mcp-server/tool-reference/get_participant_profile) * Job: Return team, person, or university profile data with normalized refs and optional season context. * Source ownership: GSD Lookup primary, On Universities enrichment optional * Use it when: Use it for team hubs, player hubs, and participant identity pages. * Do not use it when: the host only needs a roster list or one event’s lineups/stat line. ### [`get_venue_profile`](/sports-mcp-server/tool-reference/get_venue_profile) * Job: Return venue identity, geography, timezone, and normalized refs. * Source ownership: On Sports Venues primary, GSD enrichment optional * Use it when: the product needs venue context, travel/location framing, or venue-linked watchability browse flows. * Do not use it when: the answer is really about a competition, team, or event instead. ### [`get_roster`](/sports-mcp-server/tool-reference/get_roster) * Job: Return roster data for a team inside one competition context. * Source ownership: GSD Lookup * Use it when: the host needs the season-context roster and not just a single-event lineup. * Do not use it when: Do not use it for people stats, lineups, or general team identity questions. ## Next steps * Use [Tool Catalog](/sports-mcp-server/tools/tool-catalog) when you want the full 1.4.1 surface in one place. * Use [ID Acquisition and Tool Sequencing](/sports-mcp-server/tools/id-acquisition-and-tool-sequencing) when the host still needs provider refs or a safer tool order. * Use [Prompt-to-Tool Mapping](/sports-mcp-server/prompt-to-tool-mapping) when you want a proven low-token workflow for a real user prompt.
