How do I use RunFast in ChatGPT and Claude?
Updated
Add livedot to ChatGPT or Claude as a custom connector, with the address https://livedot.me/mcp. Then ask in plain words: where a runner is in a race, how a race is going, or what the heat and wind will be on race day. It’s free, needs no sign-in and only reads public information.
What it is
livedot, the family RunFast belongs to, has a connector for AI assistants. Once it’s added, ChatGPT or Claude can read RunFast’s and Windline’s public live pages and forecasts, and answer with a map in the chat.
- Free, with no account and no sign-in.
- Read only. It can’t change anything, post anything or see anything private.
- The same numbers as RunFast. The heat, the wind and the weather cost come from the same forecast engine as the app and every live page.
The address is https://livedot.me/mcp. You add it once.
Add it to Claude
Custom connectors work on every Claude plan, on claude.ai and in Claude Desktop. The Free plan includes one.
- Go to Customize > Connectors.
- Tap + Add, then Add custom connector.
- Name it
livedotand pastehttps://livedot.me/mcpas the server URL. Tap Continue. - If Claude asks about signing in, choose No sign in. Tap Continue, then Add.
To use it in a chat, tap + at the bottom left, then Connectors, and check livedot is switched on.
On a Team or Enterprise plan, an owner adds it for everyone instead, from Organization settings > Connectors.
Add it to ChatGPT
ChatGPT lets you add your own connector on some plans. OpenAI’s help lists Business, Enterprise and Edu workspaces on the web, and Pro accounts in developer mode with read-only tools, which is all livedot needs.
- Open Plugins in ChatGPT (chatgpt.com/plugins).
- Tap +, then Add custom MCP server.
- Name it
livedot. Under Connection, pastehttps://livedot.me/mcp. - For authentication, choose none: livedot needs no sign-in.
- Read the warning, tap I understand and want to continue, then Create as a plugin.
- Install the plugin, open a new chat, type @ and choose livedot.
ChatGPT’s menus change often and differ between plans. If you can’t find Add custom MCP server, OpenAI’s guide Connecting custom MCP servers in ChatGPT has the current steps for your plan.
What to ask
Ask the way you’d ask a friend. A few to try:
| Ask | What you get |
|---|---|
| “Where’s Megan in the Comrades demo?” | Where she is, her pace, her goal, the heat where she is and on the road ahead, her finish time and a Follow live link. |
| “How’s the Comrades demo going?” | How long it’s been under way, how many runners are on the map, who’s out front. |
| “Fly the Comrades.” | The course from the air, in the chat, coloured by how hard the weather makes each stretch. |
| “What will the weather be like for the NYC Marathon?” | The heat and wind along the course at the times runners get there, with the rating. |
The demo race runs every day, so you can try it any time. See the live demo.
To find a real runner by name, they need to be on a public race with Findable by anyone switched on. If they sent you their livedot link (livedot.me/their-name) or their follow link, paste it into the chat instead. See following a runner in ChatGPT.
Units
Answers come in your units. ChatGPT tells livedot where you are, so miles and °F in the US, km and °C in most places. Claude doesn’t, so answers lead with the race’s own units and give the others in brackets, such as “km 79 (mile 49)”. You can always ask for miles or kilometres.
Privacy
The connector reads only what anyone can see on RunFast’s and Windline’s public live pages:
- by name, a runner shows up only on a public race, and only if they chose to be findable;
- no position is shared while they’re stopped or paused, or near the start or finish;
- names show as first name and initial, such as “Megan N.”;
- nothing is kept about who asked.
Private runs never reach it.
Every answer ends with a thank-you to the sponsor who keeps livedot, RunFast and Windline free.
