Search for files matching criteria
AI agents call search_files to retrieve information from Mail Cal Drive 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 files based on search criteria without creating, modifying, deleting, or executing anything. It has no side effects beyond returning matching results. The presence of write/destructive sibling tools (delete_event, copy_file, create_folder) confirms this is distinct and safely classified as Read.
From the tool's definition search_files is described as 'Search for files matching criteria' — a retrieval operation with no modification or deletion. File search is a read-only query against stored data.
Attacks that exploit this kind of access
Search for files matching criteria. It is categorised as a Read tool in the Mail Cal Drive MCP Server, which means it retrieves data without modifying state.
Register the Mail Cal Drive MCP server in PolicyLayer and add a rule for search_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 Mail Cal Drive. Nothing to install.
search_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 search_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 search_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.
search_files is provided by the Mail Cal Drive MCP server (rumbitopi/mail-cal-drive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
