WHAT IT DOES

What repo-clone does on Build

AI agents invoke repo-clone to trigger actions in Build. 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.

RISK

Why repo-clone is rated High

Cloning a repository initiates an external network operation and writes data to the filesystem. While it can be undone by deleting the cloned directory, the primary action is executing an external command (git clone) with side effects that go beyond a simple write. An AI agent could misuse this to pull malicious code or fill disk space.

From the tool's definition Clones a GitHub repository — triggers an external operation (network fetch + filesystem write) that depends on the repository argument supplied.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs repo-clone safely

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

repo-clone Rate-limited

repo-clone 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "repo-clone": {
      "limits": [
        {
          "counter": "repo-clone_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Build, apply this rule, and every repo-clone call is checked against it from then on.

FAQ

Questions about repo-clone

What does the repo-clone tool do? +

Clones a GitHub repository. Returns structured data with success status, repo name, target directory, and message. It is categorised as a Execute tool in the Build MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on repo-clone? +

Register the Build MCP server in PolicyLayer and add a rule for repo-clone: 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 Build. Nothing to install.

What risk level is repo-clone? +

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

Can I rate-limit repo-clone? +

Yes. Add a rate_limit block to the repo-clone 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 repo-clone completely? +

Set action: deny in the PolicyLayer policy for repo-clone. 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 repo-clone? +

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