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
1/1 tools missing one or more hints — quip_read_spreadsheet (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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.
Secrets not logged
1 secret value sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@1.21.0 (high), @modelcontextprotocol/sdk@1.21.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
