Environment

Name	Required	Notes
BLENDER_PATH	No	Absolute path to the Blender 3.0+ executable. Leave unset to discover it on PATH and at the platform's standard install locations.
BLENDER_MCP_TIMEOUT_MS	No	Ceiling for one Blender job in milliseconds. Renders and heavy conversions are the slow ones.
BLENDER_MCP_WORKDIR	No	Directory for outputs written when a tool is called without an explicit output path.
BLENDER_MCP_ALLOW_PYTHON	No	Set to 0 to withdraw blender_run_python, which executes caller-supplied Python inside Blender, from the advertised tool list.
BLENDER_MCP_INLINE_IMAGE_BYTES	No	Ceiling on inlined image bytes. Past this the image stays on disk and the response says where.
BLENDER_MCP_INLINE_IMAGE_PX	No	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	No	How many Blender processes may run at once. Further calls queue rather than compete for memory.
THREE_WS_BASE	No	Base URL of the three.ws deployment backing blender_forge_import.
THREE_WS_FORGE_TIMEOUT_MS	No	Ceiling for one text-to-3D generation in milliseconds.
THREE_WS_FORGE_PROVIDER_KEY	No	Meshy/Tripo API key for the bring-your-own-key geometry lane. The default image lane is free and needs no key. Secret.
