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 Celestial Navigation.

  1. 01

    Calculate sight reduction

    This capability calculates the intercept and true azimuth for a specific celestial sight.

  2. 02

    Get correction factors

    Use this to get the necessary atmospheric and physical correction values for an observation.

  3. 03

    Verify position validity

    This capability checks if an assumed position is geographically plausible for the given observation.

Real work

What teams actually run

01

Automated Sight Reduction

An agent takes raw altitude and GHA data to find the intercept and azimuth.

02

Error Checking

Your agent uses the validation capability to ensure an assumed position isn't impossible.

03

Correction Management

The agent pulls specific refraction and parallax values for a Moon observation.

04

Navigation Planning

Use the calculated azimuth to plot a course based on celestial sightings.

One connector, every AI

Celestial Navigation 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 Celestial Navigation 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.

Connect your client

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 Celestial Navigation, so you can see the experience inside your AI.

It does not authenticate your account with Celestial Navigation. 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 Celestial Navigation owners hand off.

This MCP is built for professionals who need to bridge the gap between celestial observations and digital navigation agents.

  • 01

    Navigators

    Hand off the tedious sight reduction math to your agent.

  • 02

    Maritime Engineers

    Use the agent to verify position plausibility and atmospheric corrections.

  • 03

    Astronomy Researchers

    Automate the calculation of azimuth and intercept for celestial bodies.

FAQ

Questions Celestial Navigation owners ask.

  • 01

    What celestial bodies can I use with this MCP?

    The capabilities are designed to work with the Sun, the Moon, and stars.

  • 02

    How does the MCP handle atmospheric errors?

    The get_correction_factors capability provides specific values for dip, refraction, parallax, and semidiameter.

  • 03

    Can my agent check if my position is wrong?

    Yes, the verify_position_validity capability checks if an assumed position is geographically plausible for your observation.

  • 04

    What kind of math does the sight reduction capability do?

    It calculates the intercept and the true azimuth for a celestial sight.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP so it is ready to use immediately after you connect your client.

  • 06

    What is a sight reduction?

    Sight reduction is the process of calculating the intercept and azimuth to determine a vessel's position based on the observed altitude of a celestial body.

  • 07

    How do I handle atmospheric corrections?

    You can use the get_correction_factors capability to retrieve specific values for dip, refraction, parallax, and semidiameter based on your observation.

  • 08

    Can I use this for Moon observations?

    Yes, the capability supports the Sun, Moon, and stars, including specific parallax corrections required for lunar observations.
