## 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__codereview__get_reviewer_persona` `mcp__codereview__review_diff` |
| 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 `ai_code_smell_scan` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "ai_code_smell_scan" 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 input takes a statement or command to run (input.code), which can change anything it can reach.
```

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

```untrusted-server-text
The server marks "complexity_report" 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 input takes a statement or command to run (input.code), which can change anything it can reach.
```

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

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

description: "...text for accidentally-committed machine credentials and private-key material. FREE. Report..."
```

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

```untrusted-server-text
The server marks "security_deep_dive" 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 description's first verb is "run": a word for a change.
```


## Changes things (5)

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

### `ai_code_smell_scan`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Flag the tells of unreviewed AI-generated code in a source file. FREE.

Detects comments that restate the next line, leaked assistant preambles,
placeholder TODOs, shipped 'Example usage' blocks, over-broad try/except
that swallows errors, and auto-named identifiers. Typical input
{"code": "<file contents>"} returns {"reviewed_confidence": 0-100,
"hits": [{"smell": "...", "evidence": "<quoted snippet>"}], "reading":
"...", "note": "..."}.

Use on a full source file suspected of unreviewed machine authorship. Not
on a diff (review_diff), and the result is a signal to check, not proof of
authorship. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `complexity_report`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Report structural complexity of a source file, function by function. FREE.

Measures per-function length, max nesting depth, and a cyclomatic-style
branch count (if/for/while/case/&&/||/except), flagging functions too
long or too deeply nested to review confidently. Typical input
{"code": "<file contents>"} returns {"functions": N, "detail":
[{"name": ..., "start": N, "lines": N, "branches": N, "max_depth": N}],
"flags": ["..."], "note": "..."}.

Use when structure rather than correctness is the question. Not for
vulnerabilities (security_deep_dive). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `review_checklist`

- 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
Produce a focused pull-request review checklist for a language or stack. FREE.

Covers the things that actually break in production, with extra items per
language. Typical input {"language": "python"} returns {"language":
"python", "checklist": ["...", ...], "note": "..."}.

Use before a review, to decide what to look for. Not for reviewing actual
code - pass code to review_diff or security_deep_dive. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `secret_scan`

- 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.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Scan text for accidentally-committed machine credentials and private-key material. FREE.

Reports each match's location and category so it can be rotated before it
leaks. Detection is pattern-based over the common leaked-credential
formats; it never echoes the matched value back. Typical input
{"text": "<file, diff, or config contents>"} returns {"leaked": bool,
"count": N, "findings": [{"line": N, "type": "<category>"}], "note": "..."}.

Pattern matching only - a clean result is not proof, and every hit needs
human confirmation before anyone acts on it. Not a general security review
(security_deep_dive). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `security_deep_dive`

- The description's first verb is "run": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Run an OWASP-oriented security pass over a source file. PREMIUM (license).

Checks injection sinks, auth/session handling, crypto misuse,
SSRF/deserialization, and unsafe file/path handling — each finding cites
the line, the OWASP risk class, and a concrete fix direction. Typical
input {"code": "<file contents>"} returns {"issues": N, "findings":
[{"line": N, "class": "A03 Injection", "fix": "...", "code": "..."}],
"owasp_note": "..."}.

Use on one source file when vulnerabilities are the question. Not for
style or structure (complexity_report), and never a substitute for a
security professional on high-risk code. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

## Only reads (2)

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

### `get_reviewer_persona`

- The name "get_reviewer_persona" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Load the Senior Reviewer persona for consistent, high-signal reviews. PREMIUM (license).

The persona is a reviewing voice that is skeptical, specific, and kind —
demands evidence over vibes and blocks only on real risk. Takes no
arguments. Returns {"persona": ..., "identity": ..., "rules": ["...",
...], "opening_move": "..."} ready to adopt as a system prompt.

Use to keep repeated reviews consistent in voice and rigor. Not for
running a review - the scan tools do that. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

### `review_diff`

- The name "review_diff" says "diff": a word for reading.
- Tag untrusted-input: The name "review_diff" says "diff" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Risk-scan a unified diff the way a senior reviewer triages a PR. FREE.

Flags added lines matching known risk patterns — injection sinks, disabled
TLS, bare excepts, debug prints, TODOs, N+1 hints, leaked secrets — with
the new-file line number and a severity (1 low - 4 high). Typical input
{"diff": "<git diff output>"} returns {"added_lines": N, "risk_score":
0-100, "verdict": "...", "secrets": [...], "findings": [{"line": N,
"severity": 1-4, "issue": "...", "code": "..."}], "note": "..."}.

Use on a unified diff, when only the change matters. Not for whole-file
analysis (complexity_report, ai_code_smell_scan). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `codereview`:

```json
{
  "permissions": {
    "allow": [
      "mcp__codereview__review_diff",
      "mcp__codereview__get_reviewer_persona"
    ],
    "ask": [
      "mcp__codereview__ai_code_smell_scan",
      "mcp__codereview__complexity_report",
      "mcp__codereview__secret_scan",
      "mcp__codereview__review_checklist",
      "mcp__codereview__security_deep_dive"
    ],
    "deny": []
  }
}
```

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

- `mcp__codereview__review_diff`: untrusted-input
- `mcp__codereview__get_reviewer_persona`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.moltlinestudio.com/codereview: tools/list returned 7 tools to an anonymous client, including ai_code_smell_scan (write), complexity_report (write), secret_scan (write), review_checklist (write), security_deep_dive (write)
