## Facts

- 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: 3 (1 required)
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `items` | string | yes | Comma-separated items to sort |
| `order` | string | no | Sort order (asc or desc) |
| `numeric` | boolean | no | Sort as numbers |

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": "sort_items",
    "arguments": {
      "items": "<items>"
    }
  }
}
```

## Why sort_items is rated Low

Sorting is a deterministic computational operation with no side effects—it retrieves and reorganizes existing data but does not create, modify, delete, or execute external operations. This aligns with the 'Read' category for operations that query or process data without persistent changes.

From the tool's own definition: "Tool name 'sort_items' and description 'Sort a list of items' indicate a read-only operation that orders data without modifying, creating, or deleting it."

## Use case

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