## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `postmd_delete_document`

- The name "postmd_delete_document" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete a document. Password-protected documents require the password or the owner's API key; documents without a password can be deleted by anyone.
```

### `postmd_update_document`

- The name "postmd_update_document" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Update a document. Password-protected documents require the password or the owner's API key; documents without a password can be updated by anyone. Include `markdown` to replace the stored content; any metadata field replaces that field. clearPassword removes the password. Replacing the content requires notesOnReplace.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `postmd_create_document`

- The name "postmd_create_document" says "create": a word for a change.
- The description's first verb is "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Publish Markdown as a PostMD web page. No API key required — anyone can publish. Returns docCode and data.shareUrl; hand shareUrl to people. Documents have a 30-day retention period (data.retainedUntil) that extends on each read. Documents without a password can be updated or deleted by anyone; password-protected documents require the password or the owner's API key. With an API key the document belongs to that member; groupId files it into that group (key with documents:write). The returned docCode can be kept at the top of the source file in a `postmd:document` comment (format at /docs/api) so a later session finds the document.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `postmd_get_document`

- The name "postmd_get_document" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get document metadata by docCode: title, fileName, hasPassword, viewerStyle, timestamps. Public — no API key needed. Content is not included; use postmd_get_document_raw for the Markdown source.
```

### `postmd_get_document_raw`

- The name "postmd_get_document_raw" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the stored Markdown source of a document. Public — no API key needed. Password-protected documents need `password`.
```
