AI agents call codeql_list_cwes 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 performs a read-only query operation that retrieves CWE (Common Weakness Enumeration) reference data. It allows filtering by category or severity but does not modify, delete, or execute any code. The blast radius of misuse is minimal—an agent could only over-query or exfiltrate known vulnerability classifications, which are already public information.
From the tool's definition Tool name contains 'list' and description states 'List all known CWE entries', indicating retrieval of data with optional filtering. No modification, deletion, execution, or financial operations are described.
Attacks that exploit this kind of access
List all known CWE entries, optionally filtered by category or severity. 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_list_cwes: 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_list_cwes 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_list_cwes 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_list_cwes. 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_list_cwes 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.
