## Changes things (2)

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

### `act_in_ride`

- The description's first verb is "submit": a word for a change.
- Findings: warn base64-blob, warn base64-blob, warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Submit one strictly validated action for the run identified by runId. Use a payload variant allowed by the latest observation. Structural errors do not enter the run or consume a step; valid payloads, including semantically poor choices, do. Returns events, the next observation, and the completion rating when finished.
```

### `start_ride`

- The name "start_ride" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start one public simulated run for this agent to take. Returns its first observation and allowed actions. No target URL or real-world system is tested.
```

## Only reads (2)

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

### `get_scorecard`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the signed scorecard for a completed MCP run by runId. It reports this one simulated run and is not a safety certification.
```

### `list_rides`

- The name "list_rides" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Discover public behavioral test tracks and their missions.
```

## Claude Code permissions

  "permissions": {
    "allow": [
      "mcp__a2apark__list_rides",
      "mcp__a2apark__get_scorecard"
    ],
    "ask": [
      "mcp__a2apark__start_ride",
      "mcp__a2apark__act_in_ride"
    ],
