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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "numbers_get_formula",

## Why numbers_get_formula is rated Low

This tool retrieves metadata about a spreadsheet cell (its formula text) without executing it, modifying it, or triggering any side effects. It is a read-only query operation on the Numbers application, analogous to inspecting source code rather than running it. The blast radius of misuse is minimal—an AI agent could only learn what formulas exist in a spreadsheet, not alter or execute them.

From the tool's own definition: "Tool name 'numbers_get_formula' and description 'Read the literal formula behind a cell' explicitly indicate retrieval of data with no modification or execution of the formula itself."

## Use case

AI agents call numbers_get_formula to retrieve information from AirMCP 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 AirMCP:

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