AI agents call keyword_generator to retrieve information from SEO Insights MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and retrieves keyword data from an SEO API. It does not create, modify, delete, or execute any code/commands. The worst-case misuse would be gathering competitive intelligence, which has minimal blast radius and no irreversible consequences.
From the tool's definition Tool description states it 'Returns a list of related keywords with volume and difficulty metrics' - a retrieval operation with no modification, deletion, or execution of external actions.
Documented attack patterns abuse exactly the kind of access keyword_generator gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SEO Insights MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for keyword_generator:
{
"version": "1",
"default": "deny",
"tools": {
"keyword_generator": {}
}
}keyword_generator is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
