Centering Lab
Card centering measurement tool with MCP server and REST API for AI assistants
Centering Lab measures collectible card centering from photos or known front/back ratios and returns centering ceilings for PSA, BGS, CGC and SGC. It offers a free website tool that processes photos locally in the browser, a REST API with OpenAPI documentation, and a remote MCP server (https://centeringlab.com/mcp, Streamable HTTP, no API key) with tools grade_centering, get_centering_standards and measure_card_centering. API/MCP photo measurements are processed on the server in memory and discarded. Not affiliated with PSA, Beckett, CGC, SGC or TAG; TAG thresholds are excluded.
