MCP_PORT) in .env, then python main.py.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
44/44 tools missing one or more hints — my_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); count_tokens (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); extract_keywords (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +41 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
3 tools perform destructive updates without destructiveHint — delete_directory deletes at line 40 (shutil.rmtree(resolved)); delete_file deletes at line 37 (resolved.unlink()); move_file deletes at line 41 (dst.unlink())
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
37/43 tool handlers declare input schemas (86%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 12/43 tool handlers wrap calls in try/catch (28%)
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.
