The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
6/6 tools missing one or more hints — get_catalog_item_form (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_user_orders (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); place_order (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 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
Only 0/6 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
4/6 tool handlers wrap calls in try/catch (67%)
Wrap each tool handler body in try/catch and return a structured error response.
Production dependencies are patched
0 critical, 1 high severity in production deps — axios@1.16.0 (high), axios@1.16.0 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
