gRPC服务反射 - 获取服务定义

Agent View of the PolicyLayer registry record for `grpc_reflect`. HTML page: https://policylayer.com/tools/seac-25-kali-security-mcp/grpc-reflect

## Facts

- Tool: `grpc_reflect`
- Server: Kali Security MCP (`seac-25/kali-security-mcp`) — https://policylayer.com/tools/seac-25-kali-security-mcp.md
- Homepage: https://github.com/SeaC-25/Kali-Security-MCP
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why grpc_reflect is rated Low

gRPC reflection is a reconnaissance capability that queries and retrieves service definitions, method signatures, and message types from gRPC endpoints. While it performs no modifications or destructive operations, it enables information gathering about target services which could inform further attacks.

From the tool's own definition: "Tool name 'grpc_reflect' and description 'gRPC服务反射 - 获取服务定义' (gRPC service reflection - get service definition) indicate it retrieves service metadata and definitions from gRPC services without modifying them."

## Use case

AI agents call grpc_reflect to retrieve information from Kali Security 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 Kali Security MCP:

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

## 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`
