WHAT IT DOES

What submodule does on Git

AI agents use submodule to create or update resources in Git, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Git environment.

RISK

Why submodule is rated Medium

While 'list' is a read operation, the tool's primary capability is managing submodules through add (creates new submodule references), update (modifies submodule state), sync (synchronizes submodule URLs), and deinit (removes submodule initialization). These are reversible modifications to repository configuration and state.

From the tool's definition Tool description states it "Manages git submodules" and explicitly supports "add, update, sync, and deinit actions." These are write operations that modify the .gitmodules file and repository structure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs submodule safely

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

submodule Rate-limited

submodule stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "submodule": {
      "limits": [
        {
          "counter": "submodule_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about submodule

What does the submodule tool do? +

Manages git submodules. Supports list (default), add, update, sync, and deinit actions. List returns structured submodule data with path, SHA, branch, and status. It is categorised as a Write tool in the Git MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on submodule? +

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

What risk level is submodule? +

submodule is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit submodule? +

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

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

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