push_files

THE RISK

Medium Risk

Why push_files needs a policy

This tool creates or modifies data (commits files to Git) in a potentially shared repository, which is reversible via Git history/revert operations. It does not permanently delete data (Destructive), move money (Financial), or execute arbitrary code (Execute) — it specifically pushes pre-existing files.

From the tool's definition Tool performs 'Push multiple files to a GitHub repository in a single commit' — a write operation that modifies a remote repository by adding/updating versioned content.

POLICY

How to control push_files

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude TypeScript MCP Servers, and nothing reaches the server without passing your rules. This is the rule we recommend for push_files:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "push_files": {
      "limits": [
        {
          "counter": "push_files_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

push_files 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 this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about push_files

What does the push_files tool do? +

Push multiple files to a GitHub repository in a single commit. It is categorised as a Write tool in the Claude TypeScript MCP Servers MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on push_files? +

Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for push_files: 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 Claude TypeScript MCP Servers. Nothing to install.

What risk level is push_files? +

push_files is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit push_files? +

Yes. Add a rate_limit block to the push_files 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 push_files completely? +

Set action: deny in the PolicyLayer policy for push_files. 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 push_files? +

push_files is provided by the Claude TypeScript MCP Servers MCP server (ukkz/claude-ts-mcps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Claude TypeScript MCP Servers tool call.

Start from Claude TypeScript MCP Servers, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
