## Facts

- Tool: `monitor_index_build`
- Server: Mcpg (`pypi:mcpg`) — https://policylayer.com/tools/io-github-devopam-mcpg.md
- Install: `npx -y pypi:mcpg`
- Homepage: https://github.com/devopam/MCPg

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

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

## Why monitor_index_build is rated Low

Index build monitoring would query system state to report progress, performance metrics, or statistics about index construction. This is a read operation retrieving observability data. It does not create, modify, delete, execute commands, or commit financial transactions. Low severity because misuse would only expose information, not cause operational damage.

From the tool's own definition: "Tool name 'monitor_index_build' suggests observation/monitoring of an ongoing index build operation. Similar sibling tools like 'analyze_query_plan', 'analyze_lock_hotspots' are introspection/analysis functions."

## Use case

AI agents call monitor_index_build 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": {
    "monitor_index_build": {}
  }
}
```

## 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`
