List all available knowledge files.
AI agents call list_knowledge_files 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 or queries metadata about available knowledge files without creating, modifying, or deleting any data. It is a simple listing/enumeration operation typical of Read category tools. The severity is low because exposing a list of available documentation files poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'list_knowledge_files' and description 'List all available knowledge files' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available knowledge files. 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 list_knowledge_files: 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.
list_knowledge_files 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 list_knowledge_files 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 list_knowledge_files. 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.
list_knowledge_files 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.
