FEISHU_APP_ID"": "cli_xxxxxxxx",FEISHU_APP_SECRET"": "your_app_secret"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
18/18 tools missing one or more hints — feishu_create_bitable (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); feishu_add_bitable_records (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); feishu_read_bitable (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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 3/18 tool handlers declare input schemas (17%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 16 high severity in production deps — @modelcontextprotocol/sdk@1.6.1 (high), @modelcontextprotocol/sdk@1.6.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
