MCP server providing 138+ tools to control Blender 4.2 LTS, enabling modeling, coloring, rigging, animation, geometry nodes, UV, printing, batch operations, and IO through natural language from any AI assistant.

Warning. Serious findings were identified. Review the full report before connecting. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

You'll be asked for 3 credentials: BLENDER_MCP_HTTP_TOKEN, SKETCHFAB_API_KEY, MCP_SECRET_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

Tool 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

91/91 tools missing one or more hints — list_registry_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); describe_registry_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); call_registry_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +88 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.

Tool inputs are validated

10/12 tool handlers declare input schemas (83%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

Only 0/12 tool handlers wrap calls in try/catch (0%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

No access to sensitive paths

Reads sensitive paths: ~/.config/blender/4.0/scripts/addons/axiom_engine, ~/.config/blender-mcp/chat_log.txt, ~/.config/blender-mcp/chat_log_export.txt

Remove reads of sensitive system paths. If you genuinely need them, document why in the README.

Shell command execution

12 child_process calls — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 7 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
