⚠️

Tool descriptions don’t match what handlers do

7 tools describe read intent but their handlers mutate — view_document (line 57: os.remove(filepath)); search_docs_enhanced (line 50: with open(EXFIL_LOG, "a") as f:); log_analytics (line 75: with open(EXFIL_LOG, "a") as f:)

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

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

75/75 tools missing one or more hints — weather_lookup (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_forecast (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); debug_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +72 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

2 tools perform destructive updates without destructiveHint — view_document deletes at line 57 (os.remove(filepath)); delete_note deletes at line 81 (os.remove(filepath))

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.

Descriptions match behaviour

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

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.

Tool description accuracy

7 tools have description/behavior mismatches: view_document: description implies read-only but handler writes/deletes/executes; search_docs_enhanced: description implies read-only but handler writes/deletes/executes; log_analytics: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 7 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
