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

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

## Why math_matrix is rated Low

Based on the server context (symbolic mathematics MCP server supporting linear algebra) and the tool name, this tool likely performs matrix computations such as determinants, inverses, eigenvalues, or decompositions. These are read/query operations with no side effects. However, the empty description significantly lowers confidence. No financial, destructive, or execute behavior is expected from a math utility tool.

From the tool's own definition: "Tool name is 'math_matrix'; description is empty or uninformative."

## Use case

AI agents call math_matrix to retrieve information from Symath-MCP 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 Symath-MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "math_matrix": {}
  }
}
```

## 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`
