AI agents call codeql_aggregate to retrieve information from Musubix without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool processes pre-existing scan results to produce summary statistics and consolidated reporting. It reads and transforms data without executing queries, modifying underlying data, executing code, or deleting information. Aggregation of security scan results is a read-only analytical operation with minimal blast radius if misused by an agent.
From the tool's definition Tool aggregates existing CodeQL scan results into a unified report with statistics. Keywords 'aggregate' and 'report' indicate data retrieval and compilation rather than execution, modification, or deletion.
Attacks that exploit this kind of access
Aggregate multiple CodeQL scan results into a unified report with statistics. It is categorised as a Read tool in the Musubix MCP Server, which means it retrieves data without modifying state.
Register the Musubix MCP server in PolicyLayer and add a rule for codeql_aggregate: 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 Musubix. Nothing to install.
codeql_aggregate 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 codeql_aggregate 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 codeql_aggregate. 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.
codeql_aggregate is provided by the Musubix MCP server (@nahisaho/musubix-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
