// key findings
⚠️
Tool descriptions don’t match what handlers do
1 tool describes read intent but its handler mutates — plugin_ops (line 287: probe.write_text("x", encoding="utf-8"))
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 4 credentials: MCP_WEB_PASSWORD, NOTEPADPP_SAMPLING_API_KEY, NOTEPADPP_SAMPLING_USE_OPENAI_KEY, OPENAI_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

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

19/19 tools missing one or more hints — agentic_notepad_workflow (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); intelligent_file_processing (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); suggest_notepad_plan (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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

1 tool perform destructive updates without destructiveHint — plugin_ops deletes at line 288 (probe.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.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — plugin_ops (line 287: probe.write_text("x", encoding="utf-8"))

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

Tool test coverage

11/19 tools referenced in tests (58%)

Write tests that reference each tool by name so every tool has at least one test.

// 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 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
