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

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

## Why sympy_solve is rated High

Solving equations runs computational logic on the server side. While it doesn't modify data or move money, it executes potentially complex symbolic mathematics (which could be resource-intensive or exploit solver logic). It fits Execute rather than Read because it actively computes/processes rather than merely retrieving stored data.

From the tool's own definition: "'Solve an equation or system of equations' — this triggers SymPy's solver engine to execute symbolic computation"

## Use case

AI agents invoke sympy_solve 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": {

      "limits": [

          "scope": "grant"
        }
