Three.ws Blender MCP Server

Three.ws Blender is an MCP integration. Drive a local Blender headlessly: inspect, convert, render and script 3D files.

Packages and local setup

The published npm package is @three-ws/blender-mcp, version 0.5.0. Its declared MCP transport is stdio.

The package declares 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.; 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_MCP_ALLOW_PYTHON: 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: Ceiling on inlined image bytes. 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.; THREE_WS_BASE: Base URL of the three.ws deployment backing blender_forge_import.; THREE_WS_FORGE_TIMEOUT_MS: Ceiling for one text-to-3D generation in milliseconds.; 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..

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
