- `include_prerelease` (boolean, optional)

## Output

- `versions` (array of string, required)

## Limits

- max versions: 5000

- max range length: 512

## Example

Request input:

```json
{
  "versions": [
    "1.0.0",
    "2.0.0",
    "1.5.0"
  ],

}
```

Response:

```json
{

      "1.0.0",
      "1.5.0"
    ]
  }
}
```

## How to call it

### MCP

Connect `https://computefirst.net/mcp` ([setup](/docs#connect)), then call `execute` with:

```json
{
  "id": "semver-filter",
  "version": "1.0.0",
  "input": {
    "versions": [
      "1.0.0",
      "2.0.0",
      "1.5.0"
    ],
    "range": "^1.0.0"
  }
}
```
