## Findings

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

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

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

```untrusted-server-text
The server marks "analyze" 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 "analyze" says "analyze": a word for reading.
```


## Changes things (2)

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

### `analyze`

- The name "analyze" says "analyze": a word for reading.
- 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
Runs the open-source hefesto-ai engine (`hefesto analyze --no-config`, free tier) on the files you send to the hosted analyzer and returns its findings: rule id, severity, file, line, message and the SARIF hefestoFingerprint/v1 fingerprint (format "sarif" adds the full SARIF 2.1.0 log). Provide files, or a single code snippet plus language. Covers Python, COBOL, the DevOps/IaC formats hefesto analyze routes, and TypeScript, JavaScript, Java, Go, Rust and C# through the multilang tree-sitter grammars (the first such request on a fresh server instance downloads the grammars and can take a few seconds longer). Limits: 20 files, 100 KB per file, 256 KB in total, 20 seconds, 10 requests per minute per IP, shared across server instances. No .hefesto.yaml is read. Files are deleted after the run; nothing is stored. For a whole repository, run `hefesto analyze .` locally.
```

### `install`

- The name "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
Return install commands for the open-source package (pip install hefesto-ai, Python 3.10+). Does not install anything on the caller's machine. No parameters.
```

## Only reads (2)

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

### `compare`

- The name "compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return a short static comparison of HefestoAI with one named tool. No live lookup and no code is inspected. Known values: sonarqube (the default when tool is omitted), snyk, github-advanced-security, semgrep, claude-code-security. Any other value is answered as sonarqube.
```

### `pricing`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return current HefestoAI prices (Free $0, PRO: $8/month, OMEGA: $19/month). Static text. Does not look up or change a subscription. No parameters.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__hefestoai__pricing",
      "mcp__hefestoai__compare"
    ],
    "ask": [
      "mcp__hefestoai__install",
      "mcp__hefestoai__analyze"
    ],
    "deny": []
  }
}
```
