Why create_pull_request_with_copilot is rated Medium
This tool creates a pull request by delegating a coding task to GitHub Copilot. Creating a pull request is a Write operation (reversible — PRs can be closed/deleted). However, severity is high because an AI agent autonomously writes and submits code changes, which could introduce vulnerabilities, unintended logic, or sensitive data exposure.

Attacks that exploit this kind of access
The rule that runs create_pull_request_with_copilot 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 create_pull_request_with_copilot, this is the rule to start with:
create_pull_request_with_copilot 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.
The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every create_pull_request_with_copilot call is checked against it from then on.
