What kind of limits does this MCP check?

It checks several AWS service quotas, including template resource counts, parameter limits, output limits, and specific limits for multi-account deployments using Stack Sets.

Does this work for all AWS regions?

The MCP provides deterministic calculations for standard AWS service quotas. Always confirm the specific regional quota you are working with.

Can I use this if my template is already failing?

Yes. You can use it to diagnose why it's failing. For instance, it can tell you if the failure is due to exceeding the resource count or the parameter limit.

Is this just a directory of AWS limits?

No. It's a live calculation capability. You input your template details or deployment plan, and the MCP calculates the limits based on those specific inputs.

How do I check if my template exceeds AWS resource limits?

You can use the check_template_compliance capability by providing your template size in KB and the total resource count.

What are the standard limits for stack outputs and parameters?

The standard limit for both outputs and parameters is 200 per stack. You can verify this using calculate_stack_capacities.

Can I check limits for Stack Sets?

Yes, use the evaluate_stack_set_limits capability to determine the maximum number of stack sets and instances per set allowed for your account.

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.

Curated set · 4 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through AWS CloudFormation Limits.

01
Assess deployment health
This capability provides recommendations on nested stack depth and change set management. It helps you keep your deployments stable and manageable.
02
Calculate stack capacities
Run this to find the maximum allowed outputs, parameters, and policies for a standard stack. It gives you hard limits based on AWS constraints.
03
Evaluate stack set limits
Use this when planning multi-account deployments with Stack Sets. It calculates the specific limits you'll hit across multiple AWS accounts.
04
Check template compliance
Use this capability to verify if your template configuration stays within standard AWS service quotas. It tells you if your template size or resource count is compliant.

Real work

What teams actually run

Large Template Rollout

You're updating a core service and the template is massive. Use this MCP to confirm the resource count stays under the standard AWS quota.

Multi-Region Deployment

You need to deploy the same stack across ten accounts. Use this to calculate the specific limits for Stack Sets across all those environments.

Optimizing Stack Parameters

You're unsure if your application needs 150 or 250 parameters. Use this to find the absolute maximum allowed parameters per stack.

Preventing Dependency Hell

Your stack depth is getting too high. Use this to check the recommended nested stack depth and avoid complexity issues.

One connector, every AI

AWS CloudFormation Limits 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 AWS CloudFormation Limits 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.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of AWS CloudFormation Limits, so you can see the experience inside your AI.

It does not authenticate your account with AWS CloudFormation Limits. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
