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 · 1 capability

We ship only the actions that matter.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through mustache.

  1. 01

    Render mustache

    This capability renders Mustache templates using provided JSON data. It handles variables, sections, and inverted sections to produce deterministic text outputs like emails or documents.

Real work

What teams actually run

01

Email Automation

Your agent takes user profile data and fills a welcome email template.

02

Financial Document Generation

The agent converts order JSON into formatted invoice bodies for PDFs.

03

System Notifications

Monitoring data is mapped into pre-built Slack or SMS message templates.

04

Standardized Reporting

Raw data sets are transformed into consistent text reports using template sections.

Automate a task

Put mustache 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

mustache 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 mustache 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 mustache, so you can see the experience inside your AI.

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

FAQ

Questions mustache owners ask.

  • 01

    What makes Mustache different from other templating engines?

    Mustache is logic-less, meaning it doesn't allow complex logic like loops-within-loops or conditional chains inside the template. It only focuses on inserting data into slots.

  • 02

    Can I use these templates in different programming languages?

    Yes, the Mustache spec is universal and works identically across JavaScript, Python, Go, Ruby, Rust, and many other languages.

  • 03

    How does this prevent my agent from breaking layouts?

    By using a structured template instead of manual string concatenation, you avoid the common errors and missing tags that happen when an agent tries to build HTML manually.

  • 04

    Is it safe to use for generating HTML?

    Yes, the logic-less nature of the engine prevents code injection because the templates can only insert data and cannot execute arbitrary code.

  • 05

    What kind of data does this MCP accept?

    The engine accepts JSON data objects to fill the variables and sections defined in your Mustache templates.

  • 06

    Why Mustache instead of Handlebars or EJS?

    Mustache has a universal spec. the same template renders identically in JS, Python, Go, Ruby, Rust, and 30+ languages. Handlebars and EJS are JavaScript-only. If your pipeline spans multiple languages, Mustache is the only portable choice.

  • 07

    Is it safe to render user-provided templates?

    Yes. Mustache is logic-less. templates can only insert data, never execute code. There's no eval(), no function calls, no file access. Intrinsically safe by design.

  • 08

    Can it iterate over lists and arrays?

    Yes. Mustache sections ({{#items}}...{{/items}}) iterate over arrays automatically. Each item's properties are accessible inside the section.
