## Exfil surface

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

| 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__upgrade-brief__dependency_upgrade_plan` `mcp__upgrade-brief__npm_breaking_changes` `mcp__upgrade-brief__npm_changelog` `mcp__upgrade-brief__npm_versions` `mcp__upgrade-brief__pypi_breaking_changes` `mcp__upgrade-brief__pypi_changelog` `mcp__upgrade-brief__pypi_versions` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__upgrade-brief__npm_breaking_changes` `mcp__upgrade-brief__npm_changelog` `mcp__upgrade-brief__pypi_breaking_changes` `mcp__upgrade-brief__pypi_changelog` |

## Findings

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```

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

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