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.

FAQ

Questions BR Business Days Calculator owners ask.

  • 01

    Does this MCP require an internet connection to calculate dates?

    No. This engine uses a hardcoded Brazilian holiday list within a V8 isolate, meaning it performs calculations locally without external network calls.

  • 02

    How does it handle Carnival in Brazil?

    The engine includes Carnival as part of its holiday logic, ensuring that adding business days correctly skips these dates.

    Can I use this with Cursor or VS Code?

    Yes. This MCP is compatible with any MCP-compatible client, including Cursor, Windsurf, and VS Code.

  • 04

    Is the holiday list updated?

    The engine uses a static, local-first list of Brazilian national holidays to ensure absolute determinism and zero latency.

  • 05

    What happens if I want to subtract days?

    You can use the add_business_days capability with negative values to subtract business days from a specific date.

  • 06

    Does it require an external API?

    No! It uses a statically compiled list of Brazilian national holidays.

  • 07

    Does it skip weekends automatically?
