"Sanity" matching MCP servers:

Enables LLM agents to query live Wildberries marketplace data — product search with pages, sorting, price filters, per-article ratings and reviews, weekly price history, and seller legal details — with honest, sanity-checked answers and automatic anti-bot handling.

Gives AI assistants read-only, key-free access to Sentinel-2 NDVI time series, ESA WorldCover land-cover shares, and Copernicus 30 m elevation and slope for a point or small area, returning the scene IDs, units, and caveats behind every number. Built-in sanity checks and a verify tool recompute key values through an independent path so the assistant can flag cloudy, low-confidence, or mismatched results instead of guessing.

Enables AI assistants to read an open laser project through LightBurn's local REST API, explain and sanity-check cut settings, change them by natural-language sentence, apply material-library entries, and drop generated SVGs onto the workspace. It also exposes machine state, position, overrides, and the loaded camera overlay for review, while never starting or stopping a job.

MCP server for discovering, triaging, and monitoring arXiv papers with transparent interest modeling and inspectable ranking.
