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.

A futuristic MCP client docking bay
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 · 2 capabilities

We ship only the actions that matter.

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

FAQ

Questions CTA Button Optimizer owners ask.

  • 01

    How does this MCP help with conversion rates?

    It identifies weak verbs and friction words that cause users to hesitate, allowing you to swap them for higher-impact alternatives.

  • 02

    Can I use this to check mobile responsiveness?

    Yes, the check_dimension_fit capability checks character counts against device constraints to prevent text overflow.

  • 03

    What kind of clients can use this?

    Any MCP-compatible client like Claude, Cursor, or Windsurf can use these capabilities once connected through Vinkius.

  • 04

    Does it provide a score for my button text?

    Yes, the analyze_copy_strength capability provides specific scores for verb strength and urgency.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.

  • 06

    How does the capability evaluate verb strength?

    The analyze_copy_strength capability compares your text against a lexicon of impactful verbs (like 'Claim' or 'Unlock') and generic verbs (like 'Click' or 'Submit') to provide a strength score.

  • 07

    Can I check if my CTA is too long for mobile screens?

    Yes, by using the check_dimension_fit capability and specifying 'mobile' as the device type, you can detect if your text exceeds character limits that might cause overflow.

  • 08

    Does this capability identify friction words?

    Yes, the analysis identifies phrases like 'free' or 'no credit card' and provides a count of these low-barrier markers to help you balance urgency with quality.
