What single_quote does on Itick
AI agents call single_quote to retrieve information from Itick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why single_quote is rated Low
This tool retrieves a single market quote (price data), which is a read-only query operation with no side effects.

Attacks that exploit this kind of access
The rule that runs single_quote safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Itick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For single_quote, this is the rule to start with:
single_quote 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 Itick, apply this rule, and every single_quote call is checked against it from then on.

Yes. Add a rate_limit block to the single_quote 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.
