# ScoreKeeperCo (scorekeeper.co) > Free online scoreboard, score keeper, leaderboard and tournament software. Runs in the browser, no download. Live scoreboards update in real time on any device, embed on websites, and overlay on OBS / Streamlabs / Twitch / YouTube streams as a score bug. Tournament brackets (single and double elimination), round robin schedules, pool play with seeded playoffs, leagues with standings, online team registration with entry-fee payments via Stripe. Free tier for casual use; Pro (one-time $19 calendar-month pass or $79/year recurring) removes the watermark and unlocks team logos, colors, sponsor logos and 32-team brackets; Studio (one-time $49 calendar-month pass or $199/year recurring) adds double elimination, CSV export and unlimited bracket size. ## Agent integration - [Start here: machine-readable service info](https://www.scorekeeper.co/api/v1): public onboarding, MCP/OAuth endpoints, supported operations, free limits and current prices - [MCP](https://www.scorekeeper.co/api/mcp): Streamable HTTP; public get_service_info, then standard OAuth with PKCE for account tools; sign-in or sign-up and explicit consent - [OpenAPI](https://www.scorekeeper.co/openapi.json): REST contract; guest POST /api/v1/agent-sessions issues a seven-day bearer token for one board, then POST /api/v1/scoreboards - [Current agent pricing](https://www.scorekeeper.co/api/v1/pricing): USD amounts, duration, availability and renewal; calendar-month passes are paid once, annual offers recur - [Agent guide](https://www.scorekeeper.co/agents-guide.md): create/score/share, safe retries, human handoff, hosted checkout and Stripe CLI Pay when available in live pricing - [Account setup guide](https://www.scorekeeper.co/agents): human instructions.
