What gsc_sites does on A3plus
AI agents call gsc_sites 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 |
|---|---|---|---|
limit | number | — | Page size 1-500, default 200. |
offset | number | — | Pagination offset, default 0. |
onlyBound | boolean | — | When true, return only sites whose domain is already GSC-bound. |
projectId | string | Yes | The A3Plus project ID. Required unless A3PLUS_PROJECT_ID env var is set. |
Parameters from the server's own tool schema.
Why gsc_sites is rated Low
Even though gsc_sites 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 gsc_sites 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 gsc_sites, this is the rule to start with:
gsc_sites 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 gsc_sites call is checked against it from then on.
Questions about gsc_sites
List a project's sites with their Google Search Console binding status. Sourced from the DB (no live Google query — fast and quota-free). ALWAYS call this FIRST before gsc_site_detail / gsc_search_analytics: a site only has GSC data when gscQueryable is true (it has a verified custom domain bound to a property). Sites still on a test subdomain have no GSC data. It is categorised as a Read tool in the A3plus MCP Server, which means it retrieves data without modifying state.
gsc_sites accepts 4 parameters: limit, offset, onlyBound, projectId. Required: 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 gsc_sites: 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.
gsc_sites 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 gsc_sites 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 gsc_sites. 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.
gsc_sites 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.
