Overview

AI-generated overview

Measures trading-card centering and checks it against PSA, BGS, CGC and SGC centering standards.

What it does
Centering Lab is a remote MCP server that measures how well a trading card is centered and compares the result with the centering ceilings and standards used by PSA, BGS, CGC and SGC. The registry description states it can measure card centering and check those graders' centering standards. No individual tools are listed in the manifest, so the exact operations are not documented here.
When to use it
Useful when preparing a card for grading and wanting a quick read on whether its centering would meet a given grader's threshold before submitting. Also relevant for sellers or collectors describing centering in a listing.
Requirements
It runs as a remote endpoint at centeringlab.com over streamable HTTP; no local package, environment variables or headers are declared. The manifest declares no authentication, so no account or API key is documented. Network access to the endpoint is required.
Before you install
The manifest declares no authentication, environment variables or headers, so no credentials are requested. The description does not state whether card images or measurements are uploaded and stored, or whether any paid grading or submission service is involved; confirm data handling and any costs with the provider before relying on results.
