## 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__nlp__knowledge_list_documents` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__nlp__analyze_sentiment` `mcp__nlp__analyze_toxicity` `mcp__nlp__answer_question` `mcp__nlp__aspect_sentiment` `mcp__nlp__check_groundedness` `mcp__nlp__check_nlp_service` `mcp__nlp__classify_text_custom` `mcp__nlp__detect_conversational_pii` `mcp__nlp__detect_language` `mcp__nlp__detect_pii` `mcp__nlp__detect_prompt_injection` `mcp__nlp__detect_protected_material` `mcp__nlp__extract_entities` `mcp__nlp__extract_key_phrases` `mcp__nlp__fraud_feedback` `mcp__nlp__fraud_score` `mcp__nlp__knowledge_ingest` `mcp__nlp__knowledge_list_documents` `mcp__nlp__knowledge_query` `mcp__nlp__link_entities_to_wikidata` `mcp__nlp__summarize_text` `mcp__nlp__translate_text` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The input carries an amount (input.amount) and a currency, so it moves money.
```

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

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

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