rsync

Syncs files between local and remote locations using rsync. WARNING: Defaults to dry-run mode for safety — set dryRun=false to actually transfer files. Returns structured transfer statistics.

WHAT IT DOES

What rsync does on Make

AI agents invoke rsync to trigger actions in Make. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why rsync needs a policy

While rsync itself does not delete or overwrite by default, it is an Execute category tool because it triggers external operations (file transfers between local and remote systems) whose effects depend on arguments (dryRun flag, source/destination parameters). An AI agent misconfiguring rsync parameters could unintentionally overwrite or sync incorrect files across systems.

From the tool's definition "Syncs files between local and remote locations using rsync" — rsync is a command execution tool that transfers files between systems.

Documented attack patterns abuse exactly the kind of access rsync gives an agent:

POLICY

How to control rsync

PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for rsync:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "rsync": {
      "limits": [
        {
          "counter": "rsync_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

rsync stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about rsync

What does the rsync tool do? +

Syncs files between local and remote locations using rsync. WARNING: Defaults to dry-run mode for safety — set dryRun=false to actually transfer files. Returns structured transfer statistics. It is categorised as a Execute tool in the Make MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on rsync? +

Register the Make MCP server in PolicyLayer and add a rule for rsync: 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 Make. Nothing to install.

What risk level is rsync? +

rsync is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit rsync? +

Yes. Add a rate_limit block to the rsync 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 rsync completely? +

Set action: deny in the PolicyLayer policy for rsync. 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 rsync? +

rsync is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Make tool call.

Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
