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

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

## Why doc is rated Low

This is a documentation generation tool that analyzes Rust code and produces diagnostic output. It is informational only - it queries/analyzes existing code and returns structured results without side effects. The tool does not modify, delete, or execute code, making it a Read operation with low severity. Misuse would result in unwanted documentation generation or information disclosure at worst.

From the tool's own definition: "Tool 'doc' generates documentation and returns structured output with warning count. It reads source code to produce documentation output with no modification to source files, deletion, execution of arbitrary code, or financial operations."

## Use case

AI agents call doc to retrieve information from Lint 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 Lint:

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

## 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`
