List changed files in a pull request
AI agents call list_pr_files to retrieve information from Forgejo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries repository metadata (PR file changes) without creating, modifying, deleting, or executing anything. It has no side effects and poses minimal risk as a standalone operation. The severity is low because even if misused by an AI agent, it only exposes file change information that is typically visible to repository collaborators anyway.
From the tool's definition Tool name 'list_pr_files' and description 'List changed files in a pull request' indicate a retrieval/query operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_pr_files 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 list_pr_files:
{
"version": "1",
"default": "deny",
"tools": {
"list_pr_files": {}
}
}list_pr_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List changed files in a pull request. It is categorised as a Read tool in the Forgejo MCP Server, which means it retrieves data without modifying state.
Register the Forgejo MCP server in PolicyLayer and add a rule for list_pr_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 Forgejo. Nothing to install.
list_pr_files is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_pr_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.
Set action: deny in the PolicyLayer policy for list_pr_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.
list_pr_files 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.
