## Facts

- Tool: `pad`
- Server: TinyFn (`https://api.tinyfn.io/mcp/all/`) — https://policylayer.com/tools/io-tinyfn-tinyfn.md
- Homepage: https://github.com/tinyfn-io/tinyfn-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 4 (2 required)
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `char` | string | no | Padding character |
| `side` | string | no | Side to pad (left, right, both) |
| `text` | string | yes | The text to pad |
| `length` | integer | yes | Target length |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "pad",
    "arguments": {
      "text": "<text>",
      "length": 0
    }
  }
}
```

## Why pad is rated Low

This tool performs a deterministic, read-only string manipulation operation (padding text). It has no external side effects, does not modify any data store, and cannot cause harm if misused beyond returning unexpected output.

From the tool's own definition: "Pad text to a specified length — pure string transformation with no side effects"

## Use case

AI agents call pad to retrieve information from TinyFn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches TinyFn:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "pad": {}
  }
}
```
