List all branches in a repository.
AI agents call list_branches to retrieve information from FastMCP GitHub Automation Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves branch information from a repository without creating, modifying, or deleting any data. It is a pure read operation that simply enumerates existing branches. The low severity reflects minimal risk even if an AI agent calls it with legitimate arguments, as it cannot cause data loss or unauthorized state changes.
From the tool's definition Tool name 'list_branches' and description 'List all branches in a repository' indicate a query/retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all branches in a repository. It is categorised as a Read tool in the FastMCP GitHub Automation Server MCP Server, which means it retrieves data without modifying state.
Register the FastMCP GitHub Automation Server MCP server in PolicyLayer and add a rule for list_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 FastMCP GitHub Automation Server. Nothing to install.
list_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_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_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_branches is provided by the FastMCP GitHub Automation Server MCP server (siddheshdongare/git-pilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
