Overview
Query by any of 17 supported muscle groups, such as chest, glutes, or triceps, with optional filters for exercise name and equipment. Every match includes the movement name, target muscle, required gear, and push or pull force direction. Paid plans include full step-by-step instructions, difficulty ratings from beginner to expert, and compound or isolation mechanics.

The tool
Once your client is connected to the VerveContext server, this appears in its tool list as ExerciseGroundingDataforAIAgents. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.
{
"name": "ExerciseGroundingDataforAIAgents",
"arguments": {
"muscle": "chest"
}
}You do not name the tool yourself; the model picks it. Asking about chest in the terms this source covers is enough for it to reach for ExerciseGroundingDataforAIAgents on its own — naming it explicitly also works, and is the way to force the call.
Connecting
One server URL covers every source in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

Arguments
These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

What the model gets back
The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

"From the starting position, breathe in and begin coming down slowly until the bar touches your middle chest.",

Why ground on it
A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong. This source returns the current value in a shape you can check, which is the difference between an answer you can cite and one you have to hedge.
Point an evaluation at count: it is the field most worth pinning a claim to, and it is either present and current or absent — never plausibly invented.
Failure modes
Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.
| Status | What it means |
|---|---|
400 / 422 | The arguments did not validate. The message names the offending one. |
401 | The OAuth session is invalid or expired — reconnect the server. |
403 | Blocked by a key restriction or an IP allow-list. Never a bad identity. |
404 | This source is not part of VerveContext. Check the catalog. |
429 | Out of credits, or a brief rate limit. The message tells them apart. |
A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
Use cases
- Workout Routine Generation
- To build customized workout splits, fitness platforms query target muscle groups and organize matching push and pull exercises into balanced daily sessions.
- Home Gym Filtering
- When users have limited equipment like dumbbells or resistance bands, fitness coaches filter movements to assemble effective training routines without heavy gym machines.
- Strength Training Logs
- Personal training portals populate exercise pickers by muscle group so lifters can record exact movements and equipment during workout sessions.
- Physical Therapy Prescriptions
- Rehabilitation clinics look up targeted movements for specific muscle groups like the lower back or neck to create safe recovery regimens for patients.
