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 · 2 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-02

2 capabilities in this set.

Part of 2 available through Sun Sign Calculator.

  1. 01

    Calculate cusp

    This capability finds the exact zodiac sign cusp for a specific date. It uses the birth year to account for orbital shifts.

  2. 02

    Get sign details

    This capability retrieves the elemental, modal, and polarity properties of a zodiac sign. Use it to find if a sign is Fire, Earth, Cardinal, or Masculine.

Real work

What teams actually run

01

Cusp Identification

Your agent determines the exact sign for someone born on a transition date by checking the specific year's orbital data.

02

Character Profiling

You ask your AI to retrieve the elemental and polarity traits of a sign to build a personality profile.

03

Historical Astrology

The capability calculates sign boundaries for any past year to ensure historical accuracy.

04

Automated Horoscope Generation

Your agent pulls sign details to provide context for astrological readings.

Who it's for

Built for the work Sun Sign Calculator owners hand off.

This MCP is built for developers and researchers who need precise astrological data for their agents.

  • 01

    Astrology App Developers

    They hand off the heavy lifting of orbital math to the MCP to power their apps.

  • 02

    Data Researchers

    They use the capability to pull specific elemental and modal attributes for study.

  • 03

    AI Agent Builders

    They connect this to their agents to provide accurate horoscope and zodiac context.

FAQ

Questions Sun Sign Calculator owners ask.

  • 01

    How is this different from a standard zodiac chart?

    Standard charts use fixed dates. This MCP calculates cusps based on specific birth years to account for orbital variations.

  • 02

    Which AI clients can use this MCP?

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

  • 03

    Can I find the properties of a sign?

    Yes, the get_sign_details capability provides elemental, modal, and polarity attributes for any sign.

  • 04

    Does it work for people born on the cusp?

    Yes, because it calculates boundaries based on the specific year, it can identify the exact sign for cusp births.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP for you. You just connect and start using it.

  • 06

    Why do I need to provide my birth year?

    Zodiac sign transitions (cusps) do not occur on the same calendar day every year due to Earth's orbital variations. Providing the year ensures the calculate_cusp capability identifies the precise boundaries for your specific birth period.

  • 07

    What information can I get about a zodiac sign?

    By using get_sign_details, you can retrieve the fundamental astrological attributes of any sign, including its element (e.g., Fire, Water), modality (e.g., Cardinal, Fixed), and polarity (e.g., Masculine, Feminine).

  • 08

    Can this capability calculate my full astrological profile?

    Yes, by combining the calculate_cusp and get_sign_details capabilities, you can determine your sign's boundaries and its corresponding elemental and modal characteristics for a complete identity summary.
