How does this MCP calculate latency?

It uses the runtime, memory allocation, and bundle size to estimate the time difference between cold and warm starts.

Can I use this to save money on serverless?

Yes, you can use the cost comparison capability to see if on-demand or provisioned concurrency is more economical for your specific workload.

Which AI clients can use this MCP?

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

Does this work with AWS Lambda?

The capability is designed to handle characteristics common in serverless environments like AWS Lambda, focusing on runtime and memory impacts.

How do I get started?

Simply connect your client to the Vinkius platform, and the capabilities will be immediately available for your agent to call.

How does the latency estimation work?

The estimateLatencyImpact capability uses runtime-specific weights and considers your package size and memory allocation to calculate the latency delta. Capabilities available: estimate_latency_delta, calculate_cold_start_probability, compare_cost_models.

Can I use this for AWS Lambda?

Yes, the capabilities are highly effective for analyzing parameters like memory size and execution duration used by providers like AWS.

How do I calculate cost savings?

Use the compareConcurrencyPricing capability by providing your monthly request volume and average execution duration to see the difference in costs.

Connect Serverless Cold Start Estimator to your AI

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Predict latency and costs before you deploy your functions.

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 · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Serverless Cold Start Estimator.

01
Compare cost models
Compares the monthly financial impact of On-Demand versus Provisioned Concurrency. Use this to decide if paying for reserved capacity is cheaper than per-request pricing.
02
Estimate latency delta
Calculates the time difference between a cold start and a warm start. You provide the runtime, memory, and bundle size to get a specific millisecond estimate.
03
Calculate cold start probability
Estimates the percentage of requests that will trigger a cold start. This capability uses your traffic patterns and idle timeouts to predict initialization frequency.

Real work

What teams actually run

SLA Validation

Check if a new Node.js function will stay within your latency requirements during a cold start.

Budget Planning

Determine if switching to provisioned concurrency is worth the cost for your specific request volume.

Traffic Pattern Analysis

Predict how often your functions will go cold during periods of low or spiky activity.

Resource Tuning

See how increasing memory allocation changes the delta between cold and warm starts.

One connector, every AI

Serverless Cold Start Estimator 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 Serverless Cold Start Estimator 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.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

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

It does not authenticate your account with Serverless Cold Start Estimator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
