Blender MCP (Fork) (mgi24/blender-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.
A simplified installation fork of the Blender MCP server, enabling control of Blender through natural language via MCP. Provides an automated setup script and easy add-on configuration.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

BLENDER_HOSTBLENDER_PORTXDG_DATA_HOMETool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
41/41 tools missing one or more hints — get_scene_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_scene_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_object_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +38 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — get_viewport_screenshot deletes at line 333 (os.remove(temp_path))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool test coverage
Only 1/41 tools referenced in tests (2%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (addon.py:537)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
