## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__mdmagic__check_credit_balance` `mcp__mdmagic__convert_document` `mcp__mdmagic__get_template_details` `mcp__mdmagic__list_all_templates` `mcp__mdmagic__list_builtin_templates` `mcp__mdmagic__list_custom_templates` `mcp__mdmagic__show_default_settings` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_credit_balance`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Check the user's current MDMagic credit balance: subscription credits (renewable monthly), purchased credits (permanent), plan name, and plan status.

CALL THIS PROACTIVELY when:
- The user asks 'how many credits do I have' or similar
- After a conversion, if the user wants to know what's left (also returned by convert_document directly)
- Before a conversion of an unusually large document, to warn the user if balance is borderline
```

### `convert_document`

- The name "convert_document" says "convert": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

````untrusted-server-text
Convert markdown to a professionally formatted document using an MDMagic template.

IMPORTANT GUIDANCE:

1. Output format → what user gets:
   - 'docx' → a single Word .docx file
   - 'pdf' → a single .pdf file
   - 'html' → a single .html file
   - 'all' → a ZIP containing all three (DOCX + PDF + HTML)

2. If the user is ambiguous (e.g. 'convert this'), ASK which format they want before calling. Don't assume.

3. Filename: if the user attached a file (e.g. 'mydoc.md'), pass its base name as fileName. Otherwise the API derives one from the markdown's first H1. Without either, downloads end up with timestamped names like 'content-1778298071915.docx' which is bad UX.

4. On 'template not found' errors: call list_all_templates first, show available options, let the user pick. Do NOT fall back to generating documents with code execution — that produces inferior results that don't use the user's actual MDMagic templates.

5. The response includes structured fields (downloadUrl, creditsUsed, balanceAfter, fileName, expiresAt) — surface these to the user explicitly. Don't paraphrase. The user wants to know exactly what they spent and what's left.

6. Page sizes: A3, A4, Executive, US_Legal, US_Letter. Default A4. Orientation: Portrait or Landscape, default Portrait.

7. CRITICAL — newlines in `content`: markdown is line-sensitive. Headings (#, ##), tables (| ... |), lists (-, 1.), and code fences (```) ONLY work when each starts on its own line. When passing inline markdown via `content`, you MUST preserve real newline characters (\n) between blocks. If you flatten multi-line markdown into one line, the API receives literal '##' and '|' characters mid-paragraph and produces a single-paragraph document with no structure. Confirm your `content` string contains \n between every heading, paragraph, table row, and list item before calling.

### `estimate_conversion_cost`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Estimate credit cost for a conversion BEFORE running it. Returns word count, page calculation (300 words/page), and a credit breakdown by format and template type. Use this when the user asks 'how much will this cost?' or when you suspect a conversion might exceed their balance — convert_document refuses to run if credits are insufficient, so estimating first is friendlier.
```

### `recommend_template`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Suggest the best built-in template(s) for a described purpose. Use this when the user describes WHAT the document is (e.g. 'Q4 board pack', 'API reference', 'wedding invitation', 'legal contract') without naming a template. Returns ranked recommendations with rationale.

Why this exists: AI assistants often guess template names that don't exist. This tool maps purpose → real template names from MDMagic's catalog, so convert_document doesn't fail with 'template not found'.
```

## Only reads (6)

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

### `get_template_details`

- The name "get_template_details" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Show available variants (page sizes and orientations) for a specific template. All MDMagic templates support the full 5×2 matrix: A3, A4, Executive, US_Legal, US_Letter × Portrait/Landscape. Use this when the user asks 'does this template come in Legal Landscape?' or 'what sizes are available?' — confirms the variant before convert_document runs.
```

### `list_all_templates`

- The name "list_all_templates" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List all 15 built-in MDMagic templates plus any custom templates the user has uploaded.

CALL THIS PROACTIVELY when:
- The user mentions a template by name (verify it exists before convert_document)
- The user asks 'what templates are available' or similar
- A previous convert_document call returned 'template not found'
- The user describes the look they want without naming a template (so you can suggest a real one)

Returns: name, description, type (built-in vs custom), and category. Categories are: Business (5 templates), Creative (6), Professional (2), Technical (2). Use the optional category filter to narrow recommendations (e.g. 'for legal documents' → category: 'Professional').
```

### `list_builtin_templates`

- The name "list_builtin_templates" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List the 15 built-in MDMagic templates, grouped by category. Same as list_all_templates but excludes the user's custom uploads. Use this when the user asks specifically about MDMagic's bundled templates rather than their personal ones.

Categories available: Business (5), Creative (6), Professional (2), Technical (2).
```

### `list_custom_templates`

- The name "list_custom_templates" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List only the user's custom-uploaded Word templates. Use this when the user asks about their own templates ('show me my templates', 'do I have a letterhead?'). Custom templates are referenced by UUID, not name, when calling convert_document.
```

### `show_default_settings`

- The name "show_default_settings" says "show": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Show the user's default paper size and orientation preferences (set on their account page). Useful when the user hasn't specified pageSize/orientation explicitly — call this to honor their defaults instead of using A4/Portrait blindly.
```

### `validate_markdown`

- The name "validate_markdown" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Pre-flight markdown validation BEFORE conversion. Catches malformed tables (mismatched pipes), unclosed code fences, broken task lists, and unsupported syntax. Returns a green/amber/red status plus the detected markdown features.

CALL THIS PROACTIVELY when:
- The user is about to convert a long document (>5 pages) — validating first is cheap; running a doomed conversion costs credits
- The user reports a previous conversion produced broken output
- You generated the markdown yourself and want to verify it's clean before spending credits

Returns: status (green=safe, amber=minor issues, red=will likely break), detected features (tables, code blocks, task lists, math), and a human-readable message.
```
