Focus area: seo, readability, structure, all (default: all)
AI agents call focus to retrieve information from Frase SEO without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to set focus parameters for SEO analysis, analogous to a filter or scope selector. It retrieves or configures the presentation of data without creating, modifying, or deleting anything. While context from sibling tools (apply_optimization, apply_ai_comment, auto_fix) suggests the server performs write/execute operations, this specific tool is limited to read-like configuration.
From the tool's definition Tool name 'focus' with description indicating it selects or filters analysis areas (seo, readability, structure, all). No verbs like 'execute', 'delete', 'modify', or 'create' are present.
Documented attack patterns abuse exactly the kind of access focus gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Frase SEO, and nothing reaches the server without passing your rules. This is the rule we recommend for focus:
{
"version": "1",
"default": "deny",
"tools": {
"focus": {}
}
}focus is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Focus area: seo, readability, structure, all (default: all). It is categorised as a Read tool in the Frase SEO MCP Server, which means it retrieves data without modifying state.
Register the Frase SEO MCP server in PolicyLayer and add a rule for focus: 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 Frase SEO. Nothing to install.
focus 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 focus 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 focus. 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.
focus is provided by the Frase SEO MCP server (frase-io/newfrase). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Frase SEO, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
