BlenderMCP connects Blender to Claude AI through the Model Context Protocol (MCP), allowing Claude to directly interact with and control Blender. This integration enables prompt assisted 3D modeling, scene creation, and manipulation.
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.

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
44/44 tools missing one or more hints — get_addon_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); disable_telemetry (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_scene_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +41 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 491 (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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
2 child_process/subprocess calls in production code — runs shell commands (addon.py:1156, src/blender_mcp/bundled/addon.py:1156)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
