Search commits by message or author
AI agents call search_commits 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 performs a search/filter operation on existing commit data, returning information without any side effects. It is purely informational and non-destructive, consistent with other sibling Read tools like 'get_file_history' and 'get_recent_commits'.
From the tool's definition Tool name 'search_commits' and description 'Search commits by message or author' indicate a query operation that retrieves commit metadata without modifying repository state.
Attacks that exploit this kind of access
Search commits by message or author. 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 search_commits: 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.
search_commits 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 search_commits 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 search_commits. 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.
search_commits 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.
