## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `sql-to-csv` |
| Category | data-tools |
| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |
| Browser execution | Use the visible action or interactive controls. |
| Browser processing | Browser; see tool notes for network behavior. |
| HTTP API | /api/v1/tools/sql-to-csv/run |
| Browser-agent interface | run_current_tool |

### Implementation notes

Parses literal MySQL-style INSERT statements. Does not execute SQL or connect to a database.

### Inputs and settings

Text input: SQL.

Example or placeholder shown in the interface (not a validated fixture):

```text
SELECT id, name FROM users;
```

Paste SQL source. This tool does not connect to a database. Up to 1,000,000 characters. Review the settings before running.

No additional settings are declared for this tool.

### HTTP contract

API calls process supplied data on the server. The website origin is `https://happytails.ai`. Server API hosting is not connected on the public website yet. Use your local server origin to test these requests.

```http
POST https://happytails.ai/api/v1/tools/sql-to-csv/run
Content-Type: application/json
```

            }
          }
        }
      }
    }
  }
}
```

#### Error and retry handling

Failures return a non-200 status and `error.code` plus `error.message`. Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Parse a declared INSERT syntax subset; never execute uploaded SQL.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

## How to use SQL to CSV

1. Enter sql in the input field.
2. Review the settings, then choose Run SQL to CSV.
3. Review the result, then use Copy result or a download link when available.

## What to expect

Convert SQL to CSV. Paste the source content and review the available settings. Inspect nested values, numbers, empty cells, and column names before reusing the result. Parses literal MySQL-style INSERT statements. Does not execute SQL or connect to a database.
