AI agents call search to retrieve information from Log without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation on log files using regex pattern matching to retrieve and return matching log entries. There are no side effects, data modifications, or irreversible actions. It falls squarely into the Read category (retrieves or queries data; no side effects).
From the tool's definition Tool name 'search' and description 'Search a log file with a regex pattern. Returns matching lines' indicate retrieval of log data with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Search a log file with a regex pattern. Returns matching lines. It is categorised as a Read tool in the Log MCP Server, which means it retrieves data without modifying state.
Register the Log MCP server in PolicyLayer and add a rule for search: 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 Log. Nothing to install.
search 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 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. 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 is provided by the Log MCP server (sheikhbasit/log-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
