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
76/76 tools missing one or more hints — list_air_quality_stations (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_air_quality (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_avalanche_bulletin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +73 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.
Descriptions match behaviour
2 tools describe read intent but their handlers mutate — get_swiss_news (line 52: itemRe.exec(xml)); search_swiss_news (line 52: itemRe.exec(xml))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
Only 2/8 tool handlers declare input schemas (25%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Tool description accuracy
get_swiss_news: description implies read-only but handler writes/deletes/executes; search_swiss_news: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
