AI agents call keyword_insights to retrieve information from Asc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Keyword analysis tools in app store contexts retrieve and analyze existing keyword performance metadata to provide insights. The verb 'analyze' combined with the server's stated purpose to 'manage apps...via natural language' suggests this queries App Store Connect data rather than executing arbitrary code, modifying app configurations, or deleting data. No side effects are implied.
From the tool's definition Tool name 'keyword_insights' and description 'Analyze your app' indicate data retrieval and analysis with no modification.

keyword_insights 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 keyword_insights 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 keyword_insights. 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.
keyword_insights is provided by the Asc MCP server (pofky/asc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
