Read the contents of multiple files from the Unity project simultaneously.

How to control read_multiple_files ↓

AI agents call read_multiple_files to retrieve information from Unity MCP Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool performs a read-only operation that retrieves and queries file contents from the project. It has no side effects, does not modify data, execute code, or trigger external operations. The action is purely informational retrieval, consistent with the 'Read' category definition.

From the tool's definition Tool name 'read_multiple_files' and description 'Read the contents of multiple files from the Unity project simultaneously' explicitly indicate retrieval of file contents with no modification or execution capability.

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 Unity MCP Integration, and nothing reaches the server without passing your rules. This is the rule we recommend for read_multiple_files:

policy.json
{
  "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.

  1. Create a free account and register Unity MCP Integration — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on read_multiple_files? +

Register the Unity MCP Integration 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 Unity MCP Integration. Nothing to install.

What risk level is read_multiple_files? +

read_multiple_files is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit read_multiple_files? +

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.

How do I block read_multiple_files completely? +

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.

What MCP server provides read_multiple_files? +

read_multiple_files is provided by the Unity MCP Integration MCP server (quazaai/unitymcpintegration). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Unity MCP Integration tool call.
