- Install: `npx -y pypi:mcp-sympy`
- Homepage: https://github.com/daedalus/mcp-sympy

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

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

## Why sympy_im is rated Low

This tool performs a read-only mathematical operation (extracting the imaginary part of a complex expression) with no side effects, data modification, or external operations. It is consistent with the other SymPy math tools on this server (acos, asin, atan, abs, etc.) which are all pure computational functions.

From the tool's own definition: "Tool name 'sympy_im' and description 'Imaginary part.' indicate a pure mathematical computation that retrieves the imaginary component of a symbolic expression."

## Use case

AI agents call sympy_im to retrieve information from Pypi:mcp Sympy without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. 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_im": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
