Get commit statistics for a repository
AI agents call get_commit_stats to retrieve information from Git Metrics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves commit statistics from a git repository without side effects. It is a read-only operation that gathers data for analysis. Even if an AI agent misuses it, the worst outcome is information disclosure about repository history, which poses minimal risk. No data is created, modified, deleted, or executed.
From the tool's definition Tool name 'get_commit_stats' with description 'Get commit statistics for a repository' — purely retrieves data about commits. Server description confirms it 'analyzes git repository metrics' and 'provides insights on commit statistics' through queries.
Attacks that exploit this kind of access
Get commit statistics for a repository. It is categorised as a Read tool in the Git Metrics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Git Metrics MCP Server MCP server in PolicyLayer and add a rule for get_commit_stats: 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 Metrics MCP Server. Nothing to install.
get_commit_stats 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_commit_stats 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_commit_stats. 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_commit_stats is provided by the Git Metrics MCP Server MCP server (jonmatum/git-metrics-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
