## Exfil surface

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

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

## Findings

- **warn** Annotations that disagree with the tool in `create_project` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_project" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_project" says "create": a word for a change.
```

- **warn** Annotations that disagree with the tool in `create_theme` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_theme" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_theme" says "create": a word for a change.
```


## Changes things (2)

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

### `create_project`

- The name "create_project" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns the Maven archetype command that scaffolds a new webforJ project, plus the follow-up commands to change into the generated directory and start the dev server. Relay the Maven command to the user via the host shell tool without modifying its arguments. Set showOptions=true to list available archetypes and the startforJ web generator instead of producing a command.
```

### `create_theme`

- The name "create_theme" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generate a webforJ theme from a primary HSL color. Returns two content blocks: a JSON summary with theme metadata, @AppTheme / @StyleSheet snippets, and recommended file paths, plus a second text block prefixed "CSS_CONTENT:" containing the full stylesheet.
```

## Only reads (7)

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

### `fqcn_validate`

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

Description, as the server wrote it:

```untrusted-server-text
Validate fully qualified class names against the catalog of types declared in webforJ source for the target version. Accepts either an explicit list of FQCNs or a Java snippet (the handler extracts its import statements). Returns unknown FQCNs with ranked similar-name suggestions. FQCNs outside the webforJ package family are not validated. Run this on any generated or edited Java before writing it to disk.
```

### `get_document`

- The name "get_document" says "get": a word for reading.
- Tag private-data: The name "get_document" says "get" and "document": it reads documents. The description's first sentence says "return" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Return the full content of an indexed webforJ documentation or sample file. Use this as a follow-up to search_knowledge_base when a search result excerpt is not enough and you need the complete page — migration guides, tutorials, long API docs. Pass the documentId from a search result.
```

### `get_versions`

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

Description, as the server wrote it:

```untrusted-server-text
Report the webforJ versions this server knows about. Returns the latest stable release, the current in-development SNAPSHOT (from the main-branch pom.xml), and an array of every major with its highest observed tag plus a `status` flag: "development" (the active SNAPSHOT line — actively changing), "stable" (the latest released major — may still receive minor/patch bugfixes), or "frozen" (older released majors — no new releases will be cut). Each major also carries `dataAvailable` indicating whether the DWC styling tools can answer questions about it. Call this FIRST when you do not know what version the user is on or which version to target — never guess.
```

### `search_knowledge_base`

- The name "search_knowledge_base" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "doc": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Search webforJ documentation, JavaDoc, and code samples for any class, method, annotation, or component, and for CSS styling concepts and rules (palette semantics, seed vs h/s, :not([theme]) pattern, dark mode, ::part limits, table styling). Returns matching snippets with titles, categories, and relevance scores. Call this before claiming any webforJ API exists. For exact --dwc-* custom property or ::part() names on a specific component, use styles_get_component instead; to verify tokens in generated CSS, use styles_validate_tokens. Pass category to narrow the search; if the category is unknown the tool errors with a ranked list of similar names plus the full set of valid categories, so you can retry. In a webforJ project the deliverable is Java (or the Kotlin DSL) using webforJ classes; search for the dedicated webforJ component before falling back to React, JSX, or hand-built HTML.
```

### `styles_get_component`

- The name "styles_get_component" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "return" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Return the real CSS styling surface of a DWC web component: CSS custom properties, shadow parts, reflected attributes, and slots. Accepts a DWC tag ("dwc-button") or a webforJ Java class name ("Button", "TextField"). Use mode="list" for every valid tag, mode="map" for Java -> tag mappings. Call this before writing CSS for a component so you never guess a var or part name. Prefer a typed Java setter on the component over CSS when both can produce the same result.
```

### `styles_list_tokens`

- The name "styles_list_tokens" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the authoritative list of global --dwc-* tokens (palette seeds, color shades, surfaces, spacing, typography, borders, etc.). Use this for any "which tokens are available for X" question — DO NOT ask the knowledge base to list tokens; it returns prose and the answer will be hallucinated. Filter with "prefix" (e.g. "--dwc-color-primary-") or "contains" (e.g. "seed") to narrow the result. For component-scoped CSS vars like --dwc-button-* use styles_get_component instead. The returned list is verbatim and complete for the filter you passed — do not add, rename, complete, or explain "implied" tokens, and do not reference tokens from other webforJ versions. If a token you expect is missing from the response, it does not exist for that version. Tokens that share a description are returned in a single entry where "names" is the list of every token that has that description; treat each name as a real, independently usable token. When writing CSS, use a token instead of hardcoding colors, spacing, or font sizes.
```

### `styles_validate_tokens`

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

Description, as the server wrote it:

```untrusted-server-text
Validate every --dwc-* reference in CSS, Java, MDX, or Markdown text against the real DWC global tokens and component CSS variables. Returns the list of invalid tokens with line numbers and ranked similar-name suggestions. Run this on any generated or edited stylesheet before writing it to disk.
```

## Claude Code permissions

    "ask": [
      "mcp__webforj__create_project",
      "mcp__webforj__create_theme"
    ],
    "deny": []
  }

```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__webforj__get_document`: private-data
- `mcp__webforj__search_knowledge_base`: private-data
- `mcp__webforj__styles_get_component`: untrusted-input
