AI agents call search_code to retrieve information from PSKit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries code content by searching for patterns. It has no side effects—it does not create, modify, delete, execute, or consume resources. It is a straightforward read operation analogous to grep or similar search utilities. The 5-tier safety pipeline mentioned in the server description provides additional assurance for safe use.
From the tool's definition Tool name 'search_code' and description 'Search for a pattern across files' indicate data retrieval with no modification. The verb 'search' and 'pattern across files' denote querying/scanning operations only.
Attacks that exploit this kind of access
Search for a pattern across files. It is categorised as a Read tool in the PSKit MCP Server, which means it retrieves data without modifying state.
Register the PSKit MCP server in PolicyLayer and add a rule for search_code: 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 PSKit. Nothing to install.
search_code 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_code 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_code. 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_code is provided by the PSKit MCP server (nickalus12/pskit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
