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
7/7 tools missing one or more hints — get_network_counters (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); preview_recommendations (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_network_stats (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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 0/7 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
