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
15/15 tools missing one or more hints — list_instances (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_instance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); delete_instance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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
14/15 tool handlers declare input schemas (93%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 1 high severity in production deps — axios@1.17.0 (high), axios@1.17.0 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
