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

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

## Why analyze_vector_search_efficiency is rated Low

This tool analyzes vector search performance—a read-only operation that queries and evaluates existing data. No description is provided, which lowers confidence slightly, but the naming pattern and sibling tools strongly indicate diagnostic/analytical intent rather than data modification, deletion, or code execution. The blast radius of misuse is low as it cannot alter state or execute arbitrary operations.

From the tool's own definition: "Tool name 'analyze_vector_search_efficiency' and sibling tools (analyze_distance_metric, analyze_hnsw_recall, analyze_lock_hotspots, analyze_query_plan, analyze_rerank_ndcg, etc.) are all analysis/inspection tools that query database metrics and performance…"

## Use case

AI agents call analyze_vector_search_efficiency to retrieve information from Mcpg 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 Mcpg:

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