## Findings

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

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


## Changes things (1)

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

### `evaluate_operation_risk`

- The name "evaluate_operation_risk" says "evaluate": 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
Check whether the actual operation inside an MCP tool call is safe before execution. Use this when one MCP tool exposes multiple operations with different side effects, so whole-tool permissions are too coarse. Provide the native MCP server identity, the tool's tools/list metadata and the intended arguments. For supported consolidated tools, distinguish read, create/add, update/mutate and delete/destructive operations. Return ALLOW, DENY, or REQUIRE_APPROVAL. Unknown, unsupported, ambiguous, or schema-changed calls fail closed with REQUIRE_APPROVAL. The evaluator never executes the source operation.
```

## Only reads (1)

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

### `describe_operation_risk_service`

- The name "describe_operation_risk_service" says "describe": a word for reading.

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__operation-risk__describe_operation_risk_service"
    ],
    "ask": [
      "mcp__operation-risk__evaluate_operation_risk"
    ],
    "deny": []
  }
}
```
