Performs a sequential, full-text search across all receipt files, up to a specified limit, in the order they were loaded (file_order). This is a slower, fallback method compared to index-based searches. :param query: The string to search for. If None, returns the first
AI agents call search_sequential to retrieve information from Command Line Interface Enhancer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite being hosted on a command-line execution server, this specific tool is purely informational—it searches and retrieves data without side effects. It cannot execute commands, modify files, delete data, or trigger external operations. The blast radius of misuse is limited to information disclosure, which poses low risk.
From the tool's definition Tool performs a 'sequential, full-text search across all receipt files' with no modification, deletion, or execution capabilities. It 'returns' search results as a read operation with a query parameter.
Attacks that exploit this kind of access
Performs a sequential, full-text search across all receipt files, up to a specified limit, in the order they were loaded (file_order). This is a slower, fallback method compared to index-based searches. :param query: The string to search for. If None, returns the first. It is categorised as a Read tool in the Command Line Interface Enhancer MCP Server, which means it retrieves data without modifying state.
Register the Command Line Interface Enhancer MCP server in PolicyLayer and add a rule for search_sequential: 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 Command Line Interface Enhancer. Nothing to install.
search_sequential 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_sequential 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_sequential. 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_sequential is provided by the Command Line Interface Enhancer MCP server (jon2allen/mcp_command_serv). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
