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
94/94 tools missing one or more hints — add (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_folder (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); delete_folder (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +91 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.
Destructive tools are labelled
9 tools perform destructive updates without destructiveHint — delete_folder deletes at line 51 (os.rmdir(folder_path)); delete_folder deletes at line 51 (os.rmdir(folder_path)); delete_folder deletes at line 51 (os.rmdir(folder_path))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
74/94 tool handlers declare input schemas (79%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
50/94 tool handlers wrap calls in try/catch (53%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
