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

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

## Why sympy_matrix_LU is rated High

This tool executes a mathematical computation (LU decomposition of a matrix) using SymPy's symbolic math engine. It runs code/computation but has no side effects on data, files, or external systems. Severity is low as it is purely computational with no destructive or financial implications.

From the tool's own definition: "LU decomposition — performs matrix factorization computation via SymPy"

## Use case

AI agents invoke sympy_matrix_LU 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:
