Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file
AI agents call read_multiple_files to retrieve information from FilesystemMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves data from the filesystem without any side effects. It performs concurrent read operations on multiple files, which is a standard query/read operation. Even though the server supports destructive operations (delete_file, delete_lines) and writes (append_to_file, edit_file), this specific tool is limited to non-destructive data retrieval, making it the lowest severity category.
From the tool's definition Tool name is 'read_multiple_files' and description states it reads file contents; no modification, deletion, or execution mentioned. The phrase 'read the contents of multiple files' and comparison capability confirm retrieval-only functionality.
Attacks that exploit this kind of access
Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file. It is categorised as a Read tool in the FilesystemMCP MCP Server, which means it retrieves data without modifying state.
Register the 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 FilesystemMCP. 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 Filesystem MCP server (rijadalisic/filesystemmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
