# The Blender MCP server on nh3-dev, reaching the add-on socket over an SSH tunnel

`[2026-09-27]` **The Blender MCP server on nh3-dev, reaching the add-on socket over an SSH tunnel.** Every tool worked except `get_viewport_screenshot`, which had Blender write a file for the SERVER to read ("Screenshot file was not created"). The server now runs inside the Blender container over ssh+docker-exec stdio. That also means no port is published. → `stacks/blender/README.md`
