## 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__und-assay__get_changes` `mcp__und-assay__resolve_identifier` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__und-assay__get_evidence` `mcp__und-assay__get_setup` `mcp__und-assay__resolve_identifier` |
| 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 `check_before_install` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_before_install" 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 "check_before_install" says "install": a word for a change.
```

- **info** The word "credentials" in `get_changes` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...added artifact sources, newly requested credentials."
```


## Changes things (1)

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

### `check_before_install`

- The name "check_before_install" says "install": 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
Evidence summary for an MCP server before you install or connect it: publisher identity level, provenance, known vulnerabilities, install scripts, maintenance, open warnings, checks that could not run, and recent changes. No warnings is NOT a safety guarantee.
```

## Only reads (7)

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

### `get_changes`

- The name "get_changes" says "get": a word for reading.
- Tag private-data: The description's first sentence says "credential": it reads secrets.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Metadata changes between consecutive published versions: new network hosts, replaced or added artifact sources, newly requested credentials.
```

### `get_evidence`

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

Description, as the server wrote it:

```untrusted-server-text
A single assertion of a tool (by field name) with the evidence records behind it: URL, fetch time, SHA-256.
```

### `get_publisher`

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

Description, as the server wrote it:

```untrusted-server-text
How a publisher is identified across ecosystems (MCP namespace, domain, GitHub, packages) and the state of each link.
```

### `get_setup`

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

Description, as the server wrote it:

```untrusted-server-text
One stable answer (schema_version 1) for connecting an MCP server: its validated remote URL and transport, packages, copy-paste setup for Claude Code and JSON configs, warnings by severity, checks that could not run, and contradicted claims. auth is null until Assay has checked the sign-in metadata of the server. Never a safety rating.
```

### `get_tool`

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

Description, as the server wrote it:

```untrusted-server-text
Every assertion for a tool with its state (VERIFIED, CLAIMED, CONTRADICTED, STALE, UNKNOWN), reason, check and evidence records.
```

### `resolve_identifier`

- The name "resolve_identifier" says "resolve": a word for reading.
- Tag private-data: The description's first sentence says "resolve" and "repository": it reads repositories.
- Tag untrusted-input: The description's first sentence says "resolve" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Resolve an MCP server name, catalog id or GitHub repository URL to the real registry entry. If there is no exact match, returns the closest real names so look-alikes and invented names can be caught. No account needed.
```

### `search_tools`

- The name "search_tools" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search cataloged MCP servers by keywords. Returns classification (verified_publisher = the publisher proved control of a domain or verified GitHub org, NOT that a company named in the tool made it / community / not_analyzed), identity level and warning counts.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `und-assay`:

```json
{
  "permissions": {
    "allow": [
      "mcp__und-assay__get_setup",
      "mcp__und-assay__resolve_identifier",
      "mcp__und-assay__search_tools",
      "mcp__und-assay__get_tool",
      "mcp__und-assay__get_publisher",
      "mcp__und-assay__get_changes",
      "mcp__und-assay__get_evidence"
    ],
    "ask": [
      "mcp__und-assay__check_before_install"
    ],
    "deny": []
  }
}
```

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

- `mcp__und-assay__get_setup`: untrusted-input
- `mcp__und-assay__resolve_identifier`: private-data, untrusted-input
- `mcp__und-assay__get_changes`: private-data
- `mcp__und-assay__get_evidence`: untrusted-input
