AI agents call symbolic_detect_hallucinations 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 analyzes generated code to identify hallucinations (non-existent APIs, modules, symbols) and reports findings. It reads and inspects data without creating side effects, modifying state, executing code, or destructing data. The analysis is informational only, making it a Read operation with low severity since misuse would only expose information without operational impact.
From the tool's definition Tool name and description indicate detection/analysis only: 'Detect hallucinated references' and 'symbolic_detect_hallucinations'. No modification, execution, deletion, or financial operations are described.
Attacks that exploit this kind of access
Detect hallucinated references (non-existent APIs, modules, symbols) in generated code. 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 symbolic_detect_hallucinations: 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.
symbolic_detect_hallucinations 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 symbolic_detect_hallucinations 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 symbolic_detect_hallucinations. 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.
symbolic_detect_hallucinations 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.
