AI agents call rules to retrieve information from Starlog without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing project documentation (guidelines, standards, rules). It performs a query operation that returns information without creating, modifying, deleting, or executing anything. No financial, destructive, or code execution implications. The blast radius of misuse is minimal—an agent could only view documentation it may not have been intended to see, but cannot alter or act upon it.
From the tool's definition Tool description states 'View project guidelines and standards' and 'check what coding standards and project rules have been established.' The verb 'view' and 'check' indicate read-only retrieval of existing data with no modification or side effects.
Attacks that exploit this kind of access
View project guidelines and standards. Use this to check what coding standards and project rules have been established. It is categorised as a Read tool in the Starlog MCP Server, which means it retrieves data without modifying state.
Register the Starlog MCP server in PolicyLayer and add a rule for rules: 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 Starlog. Nothing to install.
rules 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 rules 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 rules. 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.
rules is provided by the Starlog MCP server (sancovp/starlog-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
