List branches for a repository accessible by a GitHub App
AI agents call list_github_app_branches to retrieve information from Coolify MCP Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about GitHub repository branches without creating, modifying, deleting, or executing any code. It is a passive data retrieval operation with no capability to alter state. The blast radius of misuse is minimal—an attacker could only enumerate branch information already visible in a repository they have access to through the GitHub App. Classified as Read with low severity.
From the tool's definition Tool name 'list_github_app_branches' and description 'List branches for a repository' indicates a retrieval operation with no side effects. The verb 'list' is explicitly a Read operation per the classification rules.
Attacks that exploit this kind of access
List branches for a repository accessible by a GitHub App. It is categorised as a Read tool in the Coolify MCP Tools MCP Server, which means it retrieves data without modifying state.
Register the Coolify MCP Tools MCP server in PolicyLayer and add a rule for list_github_app_branches: 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 Coolify MCP Tools. Nothing to install.
list_github_app_branches 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_github_app_branches 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_github_app_branches. 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_github_app_branches is provided by the Coolify MCP Tools MCP server (jplansink/coolify-mcp-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
