List all cached versions of a repository across different branches. Shows information about each cached branch including paths, strategies, and metadata.
AI agents call list_repository_branches to retrieve information from Code Expert MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about cached repository branches without modifying, deleting, executing code, or performing financial operations. It is a pure read operation with minimal blast radius if misused—an AI agent could only gain visibility into branch information already cached by the system.
From the tool's definition Tool name 'list_repository_branches' and description 'List all cached versions of a repository across different branches' indicate a retrieval operation with no side effects.

List all cached versions of a repository across different branches. Shows information about each cached branch including paths, strategies, and metadata. It is categorised as a Read tool in the Code Expert MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Code Expert MCP Server MCP server in PolicyLayer and add a rule for list_repository_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 Code Expert MCP Server. Nothing to install.
list_repository_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_repository_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_repository_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_repository_branches is provided by the Code Expert MCP Server MCP server (lfnovo/code-expert-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
