Return HFSS bug database.
AI agents call get_hfss_bugs to retrieve information from Photonics Simulation MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves knowledge from a bug database—a read-only query operation. It returns pre-compiled information about known issues in HFSS (Ansys HFSS electromagnetic simulation software) for reference and troubleshooting purposes. There are no side effects, no code execution, and no data modification. The worst-case misuse is an AI agent consuming reference data unnecessarily, which poses negligible risk.
From the tool's definition Tool name 'get_hfss_bugs' and description 'Return HFSS bug database' indicate retrieval of static reference data with no modification, execution, or destructive capability.
Attacks that exploit this kind of access
Return HFSS bug database. It is categorised as a Read tool in the Photonics Simulation MCP MCP Server, which means it retrieves data without modifying state.
Register the Photonics Simulation MCP server in PolicyLayer and add a rule for get_hfss_bugs: 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 Photonics Simulation MCP. Nothing to install.
get_hfss_bugs 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 get_hfss_bugs 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 get_hfss_bugs. 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.
get_hfss_bugs is provided by the Photonics Simulation MCP server (llldyyy/photonics-simulation-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
