What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

Past this the image stays on disk and the response says where. · BLENDER_MCP_INLINE_IMAGE_PX=Longest edge of the render copy returned inline in a tool result. The full-resolution PNG is always written to disk. · BLENDER_MCP_MAX_CONCURRENCY=How many Blender processes may run at once. Further calls queue rather than compete for memory. · BLENDER_MCP_TIMEOUT_MS=Ceiling for one Blender job in milliseconds. Renders and heavy conversions are the slow ones. · BLENDER_MCP_WORKDIR=Directory for outputs written when a tool is called without an explicit output path. · BLENDER_PATH=Absolute path to the Blender 3.0+ executable. Leave unset to discover it on PATH and at the platform's standard install locations. · THREE_WS_BASE=Base URL of the three.ws deployment backing blender_forge_import. · THREE_WS_FORGE_PROVIDER_KEY=Meshy/Tripo API key for the bring-your-own-key geometry lane. The default image lane is free and needs no key. · THREE_WS_FORGE_TIMEOUT_MS=Ceiling for one text-to-3D generation in milliseconds. |

Paste this line into a README of your own. The badge states how many values the registry holds for the entry and when it last looked, and it links back to this page.

The image is drawn again on every request, so it always reports the current state while the pasted line stays as it is. It carries no rating and no traffic light – only the two measured figures.
