What is the difference between RER and MER?

RER is the Resting Energy Requirement, which is the baseline calories a pet needs at rest. MER is the Maintenance Energy Requirement, which adds lifestyle multipliers to the RER to account for activity or life stage.

Which AI clients can use this MCP?

You can use this MCP with any compatible client including Claude, Cursor, Windsurf, and VS Code.

Can I calculate calories for a pregnant cat?

Yes, the capability includes lifestyle factors like pregnant and lactating to adjust the caloric calculations.

Do I need to provide the multipliers myself?

No, you can use the list_lifestyle_factors capability to see all the multipliers the MCP supports.

Is this capability accurate for veterinary use?

The MCP uses veterinary-standard calculations for RER and MER based on metabolic weight.

Resting Energy Requirement (RER) is the minimum amount of energy needed to maintain vital functions while the animal is at rest.

How do I know which lifestyle factor to use?

You can use the list_lifestyle_factors capability to see a complete list of available keys like 'neutered' or 'athletic'.

Does this account for different breeds?

The calculation is based on metabolic weight (kg^0.75), which is a standard veterinary approach that inherently accounts for scaling across different sizes.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Pet Calorie Needs.

01
Calculate rer
This capability calculates the Resting Energy Requirement (RER) to find the baseline calories a pet needs at rest.
02
Calculate mer
This capability determines the Maintenance Energy Requirement (MER) by applying lifestyle multipliers to the baseline.
03
List lifestyle factors
This capability provides a list of all available activity and physiological multipliers used for caloric adjustments.

Real work

What teams actually run

Weight Management

Your agent uses the weight loss factor to calculate reduced caloric needs for overweight pets.

Puppy and Kitten Care

You calculate specific needs for growing animals based on their metabolic requirements.

Athletic Dog Training

The capability adjusts caloric intake for high-activity working dogs using the athletic multiplier.

Clinical Nutrition Planning

Veterinarians use the data to create precise feeding plans for patients in recovery.

Automate a task

Put Pet Calorie Needs to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Pet Calorie Needs works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Pet Calorie Needs to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
