How to validate spatial reasoning with your AI

Connect this MCP to your agent to turn vague geographic guesses into precise mathematical certainties. It replaces LLM intuition with real-world trigonometry.

Short answer

How can I check if my AI's distance estimates are wrong?

Your agent uses the calculate_distance tool to run actual spherical trigonometry on coordinates. This provides a hard mathematical truth to compare against the agent's internal logic. You'll see exactly where its spatial reasoning fails.

The results.

Where the data lands.

The engine processes coordinates to produce these specific outcomes.

VERIFIED

Accurate distance checks

The AI uses the tool to confirm if a distance between two points is mathematically sound. You get a precise number instead of a guess.

DETECTED

Hallucination alerts

When the agent's estimate deviates from the tool's output, you catch the spatial error immediately. This prevents bad data from moving downstream.

REFINED

Better prompt logic

You can use the tool's results to adjust how your agent thinks about geography. This makes future spatial reasoning more reliable.

MANUAL

Human intervention

If the tool and the agent disagree significantly, you decide whether to trust the math or investigate the agent's context. The AI won't make this final judgment for you.

The workflow

What your AI does when coordinates arrive.

The agent stops guessing and starts calculating.

  1. Identify coordinates

    The agent pulls latitude and longitude pairs from your chat, a spreadsheet, or a database.

    calculate_distance

  2. Run trigonometry

    The agent invokes the tool to calculate the great-circle distance between those points.

    calculate_distance

  3. Compare results

    The agent weighs its own internal estimate against the tool's precise output.

    calculate_distance

  4. Flag errors

    The agent reports the discrepancy to you if the math doesn't match its reasoning.

FAQ

How the engine behaves

  • 01

    Can the AI change the coordinates in my files?

    No. The tool only reads coordinates to perform calculations; it cannot modify your original data.

  • 02

    Does the AI automatically fix its own mistakes?

    No. The AI identifies the discrepancy, but you must decide how to correct the agent's logic or the underlying data.

  • 03

    What kind of distance does it calculate?

    It uses the Haversine formula to calculate the great-circle distance between two points on a sphere.

  • 04

    Can I use this to find the shortest driving route?

    No. This tool calculates straight-line spherical distance, not road network distance or travel time.

  • 05

    Does it work with any coordinate format?

    The agent must be able to extract latitude and longitude from your input for the tool to work.
