AI agents call query_project_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.
Given the tool name and context (a documentation workflow MCP server managing project rules), 'query_project_rules' most likely retrieves or searches existing rules without modification. The empty description reduces confidence but does not change the assessment, as the naming convention and sibling tools all suggest read operations. No evidence of side effects, deletions, or external state changes.
From the tool's definition Tool name 'query_project_rules' uses the verb 'query', which conventionally indicates data retrieval. The empty description prevents higher confidence.
Attacks that exploit this kind of access
query_project_rules. 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 query_project_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.
query_project_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 query_project_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 query_project_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.
query_project_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.
