Get the current Git branch
AI agents call get_current_branch to retrieve information from Git Memory MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns the current branch name, a read-only operation with no side effects, no code execution, and no data modification. It is a simple informational retrieval, classified as Read with low severity.
From the tool's definition Tool name is 'get_current_branch' and description states 'Get the current Git branch' — purely retrieves branch information with no modification or execution of commands.

Get the current Git branch. It is categorised as a Read tool in the Git Memory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Git Memory MCP Server MCP server in PolicyLayer and add a rule for get_current_branch: 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 Git Memory MCP Server. Nothing to install.
get_current_branch 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 get_current_branch 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 get_current_branch. 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.
get_current_branch is provided by the Git Memory MCP Server MCP server (nirutyodjai/git-memory-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
