Is this vulnerability remotely exploitable?

Yes, as described, the attack can be initiated remotely if the MCP Tool's `git_operation` interface is reachable by an attacker or through a compromised client that can send crafted requests.

What level of access does an attacker need?

The attacker generally needs the capability to invoke or influence calls to the `git_operation` function. This can be as minimal as network access to the service endpoint; no local shell access is required if the server accepts requests over the network.

What is the safest general fix pattern?

The safest approach is to stop constructing shell commands from untrusted input. Use a strict allowlist of permissible operations mapped to fixed command templates and execute them via non-shell APIs that separate command and arguments, removing the ability for user input to change command structure.
