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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "vision.infer_materials",
    "arguments": {}

}
```

## Why vision.infer_materials is rated Low

This tool performs inference and analysis on material hypotheses based on observation data. It reads and processes existing data to generate insights but does not create, modify, delete, or execute external operations. The use of 'infer' and 'derive' in a visual compiler context suggests deriving conclusions from observations without side effects. No evidence of write, execute, destructive, or financial operations.

From the tool's own definition: "Tool name 'infer_materials' with description 'Infer a MaterialHypothesisSet capped by derive() over observation authorities' indicates data analysis and inference generation without modification."

## Use case

AI agents call vision.infer_materials to retrieve information from Visionmcp 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 Visionmcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "vision.infer_materials": {}
  }
}
```
