// key findings
⚠️
Tool descriptions don’t match what handlers do
1 tool describes read intent but its handler mutates — read_note (line 115: os.remove(tmp_path))
✅
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 1 credential: webdav_password
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

check_webdav_login

Check if WebDAV login is successful. Returns a message indicating success or failure.

ensure_notes_folder_exists

Ensure that the /Notes folder exists in Nextcloud. Creates it if it doesn't exist.

list_uncategorized_notes

List all Markdown (.md) files directly inside /Notes (not in subfolders).

list_categories

List all categories (directories) inside /Notes.

list_notes_of_a_category

List all notes in a given category inside /Notes.

read_note

Read a Markdown (.md) file.

edit_note

Edit a Markdown (.md) file, updating its content. Always overwrites the old file.

create_note

Create a new Markdown (.md) note.

delete_note

Delete a note file inside Notes.

rename_note

Rename a Markdown (.md) note inside Notes or a category. Overwrites the target if it already exists.

create_category

Create a new category inside Notes by creating a subdirectory.

edit_category

Rename an existing category inside Notes.

delete_category

Delete a category folder inside Notes.

// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

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

13/13 tools missing one or more hints — check_webdav_login (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ensure_notes_folder_exists (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_uncategorized_notes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 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 — read_note deletes at line 115 (os.remove(tmp_path)); edit_note deletes at line 135 (os.remove(tmp_path)); create_note deletes at line 161 (os.remove(tmp_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.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — read_note (line 115: os.remove(tmp_path))

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

Tests exist

No test files found

Add tests that exercise each declared tool.

Tool description accuracy

read_note: 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 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
