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

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

## Why sympy_limit is rated High

The tool executes a symbolic mathematics computation (limit calculation) via SymPy. While it reads/computes rather than modifying data, it runs code in a mathematical engine, making Execute the most accurate category. The blast radius is low since it only performs mathematical computations with no side effects on external systems.

From the tool's own definition: "'Compute a limit' — performs a mathematical computation using SymPy's symbolic engine"

## Use case

AI agents invoke sympy_limit 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_limit": {
      "limits": [
        {

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