Get recent commit history with messages and authors
AI agents call get_commit_history to retrieve information from Git Helper MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical metadata from a git repository. It does not execute commands, modify commits, delete data, or trigger external operations. It is a passive query operation with negligible blast radius if misused by an AI agent.
From the tool's definition Tool description states 'Get recent commit history with messages and authors' — a retrieval operation with no modification or side effects. Sibling tools (get_branch_info, get_diff, get_status, list_branches) are all read-only queries.
Attacks that exploit this kind of access
Get recent commit history with messages and authors. It is categorised as a Read tool in the Git Helper MCP MCP Server, which means it retrieves data without modifying state.
Register the Git Helper MCP server in PolicyLayer and add a rule for get_commit_history: 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 Helper MCP. Nothing to install.
get_commit_history 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_history 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_history. 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_history is provided by the Git Helper MCP server (letscodethebrain/git-helper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
