Return the keyword list for the given syntax.
AI agents call keywords-for to retrieve information from APLCart MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves keyword information associated with APL syntax. The action is read-only—it fetches data from the APLCart collection and returns it without creating, modifying, deleting, or executing anything. This matches the 'Read' category (retrieves or queries data; no side effects). The blast radius of misuse is minimal, as returning keywords poses no security, financial, or operational risk.
From the tool's definition Tool name 'keywords-for' and description 'Return the keyword list for the given syntax' indicate a retrieval operation that returns existing keyword data without modification or side effects.
Attacks that exploit this kind of access
Return the keyword list for the given syntax. It is categorised as a Read tool in the APLCart MCP Server MCP Server, which means it retrieves data without modifying state.
Register the APLCart MCP Server MCP server in PolicyLayer and add a rule for keywords-for: 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 APLCart MCP Server. Nothing to install.
keywords-for 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 keywords-for 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 keywords-for. 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.
keywords-for is provided by the APLCart MCP Server MCP server (xpqz/ac-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
