Create a new pull request
AI agents use create_pull_request to create or update resources in Forgejo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Forgejo environment.
Creating a pull request is a reversible write operation that modifies repository state by introducing a new PR object. While it has side effects (notifications, CI triggers), the action itself can be undone by closing or deleting the PR. It does not execute arbitrary code, delete data permanently, or move financial assets. The blast radius is limited to repository collaboration workflows.
From the tool's definition Tool name is 'create_pull_request' and description states 'Create a new pull request'. This creates a new artifact (pull request) within the repository system.
Documented attack patterns abuse exactly the kind of access create_pull_request gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Forgejo, and nothing reaches the server without passing your rules. This is the rule we recommend for create_pull_request:
{
"version": "1",
"default": "deny",
"tools": {
"create_pull_request": {
"limits": [
{
"counter": "create_pull_request_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_pull_request 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.

Create a new pull request. It is categorised as a Write tool in the Forgejo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Forgejo MCP server in PolicyLayer and add a rule for create_pull_request: 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 Forgejo. Nothing to install.
create_pull_request 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 create_pull_request 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 create_pull_request. 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.
create_pull_request is provided by the Forgejo MCP server (sqcows/forgejo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Forgejo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
