## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `text` | string | yes | Text to ASCII encode |

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": "ascii_encode",
    "arguments": {
      "text": "<text>"
    }
  }
}
```

## Why ascii_encode is rated Low

This is a deterministic encoding function that reads input text and returns its ASCII numeric representation. It performs no mutations, deletions, financial transactions, or arbitrary code execution. The operation is purely informational and reversible (ASCII codes can be converted back to text). Consistent with the server's purpose of offering utility functions for AI agents.

From the tool's own definition: "Tool description states 'Get ASCII codes for text' — a retrieval/query operation with no side effects. Returns encoded representation of input without modifying data."

## Use case

AI agents call ascii_encode 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": {
    "ascii_encode": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
