Read the contents of multiple files simultaneously. This is more
AI agents call read_multiple_files to retrieve information from MCP-Server-Filesystem 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 that queries and retrieves data from the filesystem without any side effects. It retrieves multiple file contents in one call but does not create, modify, delete, or execute anything. It presents minimal risk as the worst outcome is information disclosure, which is inherently less severe than write, execute, or destructive operations.
From the tool's definition Tool name 'read_multiple_files' and description 'Read the contents of multiple files simultaneously' explicitly indicate retrieval of file contents with no modification or deletion capability.
Attacks that exploit this kind of access
Read the contents of multiple files simultaneously. This is more. It is categorised as a Read tool in the MCP-Server-Filesystem MCP Server, which means it retrieves data without modifying state.
Register the MCP-Server-Filesystem MCP server in PolicyLayer and add a rule for read_multiple_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 MCP-Server-Filesystem. Nothing to install.
read_multiple_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 read_multiple_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 read_multiple_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.
read_multiple_files is provided by the MCP-Server-Filesystem MCP server (redf0x1/mcp-server-filesystem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
