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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "sympy_randMatrix",
    "arguments": {}
  }
}
```

## Why sympy_randMatrix is rated High

Generating a random matrix involves executing a computation/function call rather than merely reading existing data or writing persistent data. It has no destructive, financial, or write side effects. Severity is low as it only produces an ephemeral mathematical object with no external impact. Confidence is moderate because the description is minimal ('Random matrix') and doesn't clarify any further behavior.

From the tool's own definition: "'Random matrix' - generates a random matrix using SymPy's randMatrix function"

## Use case

AI agents invoke sympy_randMatrix to trigger actions in Pypi:mcp Sympy. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pypi:mcp Sympy:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "sympy_randMatrix": {
      "limits": [
        {

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
