AI agents invoke git_init to trigger actions in MCP File Edit. 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.
git_init runs a git operation that creates a new repository structure in a directory. It is not purely reading data, and while it creates files (.git directory), it's best classified as Execute since it triggers an external git operation. The blast radius is low since it only initializes a new repo and doesn't modify or delete existing content.

Documented attack patterns abuse exactly the kind of access git_init gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP File Edit, and nothing reaches the server without passing your rules. This is the rule we recommend for git_init:
{
"version": "1",
"default": "deny",
"tools": {
"git_init": {
"limits": [
{
"counter": "git_init_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}git_init 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.

Initialize a new git repository. It is categorised as a Execute tool in the MCP File Edit MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP File Edit MCP server in PolicyLayer and add a rule for git_init: 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 File Edit. Nothing to install.
git_init 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 git_init 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 git_init. 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.
git_init is provided by the MCP File Edit MCP server (patrickomatik/mcp-file-edit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP File Edit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
