Search all knowledge files.
AI agents call search_knowledge 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 data from a knowledge base—specifically searching documentation, rules, bugs, checklists, and recommendations for photonics simulation tools. It has no side effects, does not create, modify, or delete data, and does not execute code or commands.
From the tool's definition Tool is named 'search_knowledge' and described as 'Search all knowledge files.' The verb 'search' indicates querying or retrieving information without modification or execution of external operations.
Attacks that exploit this kind of access
Search all 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 search_knowledge: 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.
search_knowledge 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 search_knowledge 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 search_knowledge. 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.
search_knowledge 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.
