Common questions
Is Paceva safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 14 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

Paceva for developers
Paceva turns an endurance athlete's watch data into honest race predictions: ranges, checked against their own history. This repository documents the public surface: the Paceva MCP server, the OAuth 2.1 sign-in in front of it, and how Paceva connects to Intervals.icu.
The Paceva app itself is closed source. This repo is documentation and
examples only.
Connect in one minute
Server URL: https://paceva.app/api/mcp
| App | How |
|---|---|
| Claude (claude.ai, desktop, mobile) | Settings → Connectors → *Add custom connector*, paste the URL, sign in to Paceva, approve. |
| ChatGPT | Settings → Apps & Connectors → add a custom connector with the URL (some plans need developer mode). |
| Claude Code | claude mcp add --transport http paceva https://paceva.app/api/mcp, then /mcp to sign in. |
| Cursor / VS Code | One-click buttons on paceva.app/dashboard/ai, or add it as a Streamable HTTP server. |
| Anything else | Any MCP client that supports Streamable HTTP and OAuth 2.1 with PKCE. |
Then ask things like *"Should I go hard today?"*, *"What could I swim a 1500 in right now?"* or *"How did my last block of riding go?"*.
Full walkthrough: docs/connect.md.
What's here
| Doc | For |
|---|---|
| docs/connect.md | Connecting each AI app, and what to expect |
| docs/tools.md | Every MCP tool, its arguments and what it returns |
| docs/oauth.md | The OAuth 2.1 server: discovery, PKCE, client registration, tokens |
| docs/intervals-icu.md | How watch data gets in: the Intervals.icu sign-in, step by step |
| docs/data-and-privacy.md | What the AI app can and can't see |
| docs/listing.md | The MCP Registry entry (server.json) and directories to submit to |
| examples/ | curl discovery, a raw JSON-RPC call, client config snippets |
Ground rules
- Read-only. One scope,
paceva:read. No tool writes anything. - Only your own data. A token is bound to one Paceva account; it can never read anyone else's.
- Every number is labelled.
devicevalues are your watch's own (e.g. Garmin's HRV);pacevavalues are computed by Paceva. - Predictions are ranges. Tools return a low–high range and how often that range holds for you. Quote the range, not a single time.
- Revocable. Disconnect any app from Paceva → Use with AI; its tokens stop working on the next call.
Status
| Piece | Status |
|---|---|
| MCP server + OAuth | Live |
| Intervals.icu sync (Garmin, Coros, Wahoo, Polar, Suunto) | Live |
| Paceva web dashboard | Coming soon, join the waitlist |
| iPhone app (Apple Health) | Coming soon |
