# index_coverage_report

GSC-style "why pages are not indexed" report — the same reason categories as Search Console's Page indexing screen ("Crawled - currently not indexed", "URL is unknown to Google", "Not found (404)", …) with counts and sample URLs. Pass siteId for one site, or projectId for a whole-project rollup (worst sites first). Scope: built from our daily URL-Inspection sweep (up to ~100 URLs/site) — category labels match the GSC UI exactly, but counts cover inspected URLs, not whole-property totals (Google has no API for the full report). Check lastCheckedAt/staleDays before drawing conclusions. Triage guide: "URL is unknown" → discovery lag, the daily sitemap/IndexNow pushes handle it, wait 1-2 weeks; "Crawled - currently not indexed" → content-quality signal, improve the content/images; 404 → the article was deleted or its slug changed; redirect/canonical variants → usually normal, ignore.

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

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

  "method": "tools/call",
  "params": {
    "name": "index_coverage_report",
    "arguments": {}

## Why index_coverage_report is rated Low

Even though index_coverage_report only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call index_coverage_report to retrieve information from A3plus 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 A3plus:

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