Batch read multiple files concurrently with per-file mode control.
AI agents call read_multiple_files to retrieve information from Vulcan File Ops without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs data retrieval only—reading file contents in batch. No modification, deletion, execution, or financial operations are involved. The 'mode control' refers to how files are read, not what happens to them. It produces no side effects beyond I/O.
From the tool's definition Tool name 'read_multiple_files' and description 'Batch read multiple files concurrently' explicitly indicate retrieval of file contents without modification. The 'per-file mode control' suggests optional parameters for read behavior (e.g., binary vs.
Documented attack patterns abuse exactly the kind of access read_multiple_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vulcan File Ops, and nothing reaches the server without passing your rules. This is the rule we recommend for read_multiple_files:
{
"version": "1",
"default": "deny",
"tools": {
"read_multiple_files": {}
}
}read_multiple_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Batch read multiple files concurrently with per-file mode control. It is categorised as a Read tool in the Vulcan File Ops MCP Server, which means it retrieves data without modifying state.
Register the Vulcan File Ops 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 Vulcan File Ops. 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 Vulcan File Ops MCP server (n0zer0d4y/vulcan-file-ops). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vulcan File Ops, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
