WHAT IT DOES

What grep_files does on Mcp Control Plane

AI agents call grep_files to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why grep_files is rated Low

The grep_files tool performs text search operations on remote files using standard grep/ripgrep utilities. These are purely read operations with no data modification, deletion, or execution capabilities. The search parameters could potentially expose sensitive information if the control plane contains confidential data, but the tool itself has no side effects.

From the tool's definition Tool name 'grep_files' and description 'Search remote files using rg when available, falling back to grep' indicate read-only file searching operations.

RECOMMENDED RULE

The rule that runs grep_files safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For grep_files, this is the rule to start with:

grep_files Allowed

grep_files is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "grep_files": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every grep_files call is checked against it from then on.

FAQ

How do I enforce a policy on grep_files? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for grep_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 Control Plane. Nothing to install.

What risk level is grep_files? +

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

Can I rate-limit grep_files? +

Yes. Add a rate_limit block to the grep_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 grep_files completely? +

Set action: deny in the PolicyLayer policy for grep_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 grep_files? +

grep_files is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
