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 Yarn Substitution Calculator.

  1. 01

    Get gauge impact summary

    This capability provides a summary of how a gauge change will physically alter the dimensions of your finished piece. It helps you understand if your project will end up larger or smaller than intended.

  2. 02

    Analyze fiber compatibility

    Use this to check if different materials will behave similarly in your project. It compares properties like elasticity and drape between different fibers.

  3. 03

    Get substitution requirements

    This capability calculates the exact grams and skeins you need when changing yarn weight or gauge. It handles the math for yardage requirements based on your new yarn's specs.

Real work

What teams actually run

01

Emergency Substitutions

When you run out of your original yarn, use the AI to find a replacement that won't change the size of your project.

02

Pattern Testing

Check if a specific yarn weight will work with a pattern before you start stitching.

03

Material Swapping

Determine if switching from a natural fiber to a synthetic one will affect the drape of a garment.

04

Sizing Adjustments

Calculate the necessary yardage multipliers when your gauge is different from the pattern instructions.

One connector, every AI

Yarn Substitution Calculator 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 Yarn Substitution Calculator 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 Yarn Substitution Calculator, so you can see the experience inside your AI.

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

Who it's for

Built for the work Yarn Substitution Calculator owners hand off.

This MCP is built for anyone who knits or crochets and needs to make quick, accurate decisions about materials.

  • 01

    Knitting Enthusiasts

    They hand off pattern specs to the AI to find suitable yarn replacements.

  • 02

    Crochet Designers

    They use the capability to verify how different yarn weights will affect their pattern dimensions.

  • 03

    Fiber Artists

    They check fiber compatibility to ensure the structural integrity of their work.

FAQ

Questions Yarn Substitution Calculator owners ask.

  • 01

    How do I use this MCP with my AI client?

    You connect to the Vinkius catalog once, and then the capabilities are immediately available in any MCP-compatible client like Claude or Cursor.

  • 02

    Can I use this for both knitting and crochet?

    Yes, the capabilities are designed for both knitting and crochet yarn substitutions.

  • 03

    Will this tell me how many skeins to buy?

    Yes, the substitution capability calculates the exact grams and number of skeins needed based on the yarn weight you provide.

  • 04

    Does it account for fiber elasticity?

    Yes, the fiber compatibility capability analyzes how different materials will behave, such as how silk might stretch differently than alpaca.

  • 05

    How does gauge affect my project size?

    The gauge impact capability summarizes how a change in gauge will physically alter the dimensions of your finished piece.

  • 06

    How do I know if my substitute yarn is the right amount?

    You can use the get_substitution_requirements capability. By providing the original yarn specs and the substitute yarn specs, it calculates the exact grams and skeins required.

  • 07

    Can I substitute cotton for wool?

    To check this, use analyze_fiber_compatibility. It will provide a compatibility score and a warning if the lack of elasticity in cotton might affect your project's drape.

  • 08

    What happens if my gauge is different?

    The get_gauge_impact_summary capability explains how the gauge difference will change the size of your project and provides a multiplier to adjust your yardage.
