WHAT IT DOES

What patch_file does on GitHub

AI agents use patch_file to create or update resources in GitHub, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GitHub environment.

RISK

Why patch_file is rated Medium

Patching files modifies repository content (Write category), with high severity because an AI agent could apply unintended code changes that alter production logic, introduce bugs, or compromise security. However, patches are theoretically reversible through version control, preventing classification as Destructive.

From the tool's definition Tool name 'patch_file' with description indicating a path to a patch file suggests applying code changes to repository files. In GitHub context, patching files creates or modifies data reversibly through diff application.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs patch_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For patch_file, this is the rule to start with:

patch_file Rate-limited

patch_file 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.

View as policy code

policy.json

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

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every patch_file call is checked against it from then on.

FAQ

Questions about patch_file

What does the patch_file tool do? +

Path to the patch file (string, required). It is categorised as a Write tool in the GitHub MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on patch_file? +

Register the GitHub MCP server in PolicyLayer and add a rule for patch_file: 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. Nothing to install.

What risk level is patch_file? +

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

Can I rate-limit patch_file? +

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

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

patch_file is provided by the GitHub MCP server (oci:ghcr.io/aifity/omnigit-mcp:0.5.0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
