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 — gmail_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gmail_get (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gmail_get_attachment (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
11/15 tool handlers declare input schemas (73%)
Declare an inputSchema with zod/joi/yup on every tool definition.

No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
