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

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

## Why sympy_abs is rated High

This tool computes an absolute value via SymPy's symbolic math engine, which involves executing a mathematical computation. It has no side effects, no data modification, and no destructive capability. Severity is low as the blast radius of misuse is minimal — it simply returns a mathematical result.

From the tool's own definition: "MCP server that exposes SymPy's symbolic mathematics functionality; tool name 'sympy_abs' with description 'Absolute value.'"

## Use case

AI agents invoke sympy_abs 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_abs": {
      "limits": [

          "scope": "grant"
        }
