git-push · GitHub MCP Server MCP: Risk & Policy

WHAT IT DOES

What git-push does on GitHub MCP Server

AI agents invoke git-push to trigger actions in GitHub MCP Server. 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 IT NEEDS A POLICY

Why git-push needs a policy

git-push triggers an external operation that modifies the remote repository's state. It is not purely local and cannot be trivially undone (especially if force-pushing or pushing to a shared branch). It spans Write and Execute categories; since it triggers an external operation on a remote system, Execute is the most appropriate classification.

Verdict

git-push Rate-limited

git-push 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.

FAQ

Questions about git-push

What does the git-push tool do? +

Pushes committed files to the remote repository. It is categorised as a Execute tool in the GitHub MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on git-push? +

Register the GitHub MCP Server MCP server in PolicyLayer and add a rule for git-push: 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 GitHub MCP Server. Nothing to install.

What risk level is git-push? +

git-push is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit git-push? +

Yes. Add a rate_limit block to the git-push 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 git-push completely? +

Set action: deny in the PolicyLayer policy for git-push. 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 git-push? +

git-push is provided by the GitHub MCP Server MCP server (jungchihoon/github-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
