What submodule does on Build
AI agents invoke submodule 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.
Why submodule is rated High
This tool executes git submodule operations including add, update, sync, and deinit. 'deinit' can unregister submodules (potentially destructive/irreversible), while add/update/sync modify repository state. Since it spans Write and near-Destructive operations via git commands, Execute is the most appropriate category given it runs external git operations with side effects.
From the tool's definition Manages git submodules. Supports list (default), add, update, sync, and deinit actions.
Attacks that exploit this kind of access
The rule that runs submodule 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 submodule, this is the rule to start with:
submodule 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Build, apply this rule, and every submodule call is checked against it from then on.
Questions about submodule
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 Execute tool in the Build MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Build 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 Build. Nothing to install.
submodule is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
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.
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.
submodule 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.
