AI agents use remote_add to create or update resources in Git MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Git MCP Server environment.
Adding a remote modifies the local Git repository configuration by creating a new remote reference. This is a reversible write operation—the remote can be removed later with 'remote_remove'. While it doesn't directly alter the codebase, it configures the repository's connection points to external sources.
From the tool's definition Tool name is 'remote_add' and description states 'Add a remote', which creates a new Git remote configuration entry.
Documented attack patterns abuse exactly the kind of access remote_add gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Git MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for remote_add:
{
"version": "1",
"default": "deny",
"tools": {
"remote_add": {
"limits": [
{
"counter": "remote_add_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}remote_add 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.

Add a remote. It is categorised as a Write tool in the Git MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Git MCP Server MCP server in PolicyLayer and add a rule for remote_add: 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 MCP Server. Nothing to install.
remote_add is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the remote_add 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 remote_add. 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.
remote_add is provided by the Git MCP Server MCP server (sheshiyer/git-mcp-v2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Git MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
