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.
