What index_coverage_report does on A3plus
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.
| Parameter | Type | Required | Description |
|---|---|---|---|
siteId | string | — | One site. Mutually exclusive with projectId. |
projectId | string | — | Whole-project rollup. Mutually exclusive with siteId. |
Parameters from the server's own tool schema.
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.
Attacks that exploit this kind of access
The rule that runs index_coverage_report safely
PolicyLayer is an MCP gateway: it sits between your AI agents and A3plus, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For index_coverage_report, this is the rule to start with:
index_coverage_report is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect A3plus, apply this rule, and every index_coverage_report call is checked against it from then on.
Questions about 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. It is categorised as a Read tool in the A3plus MCP Server, which means it retrieves data without modifying state.
index_coverage_report accepts 2 parameters: siteId, projectId. The full parameter table on this page comes from the server's own tool schema.
Register the A3plus MCP server in PolicyLayer and add a rule for index_coverage_report: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches A3plus. Nothing to install.
index_coverage_report is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the index_coverage_report rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for index_coverage_report. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
index_coverage_report is provided by the A3plus MCP server (a3plus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
