get_commit_refs
AI agents call get_commit_refs to retrieve information from Kepler MCP GitLab Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the tool name convention, 'get_commit_refs' appears to retrieve or query commit reference information without modifying state. This is a read operation with no side effects. While the empty description reduces confidence slightly, the semantic meaning of 'get' and 'refs' in Git terminology strongly indicates a retrieval operation.
From the tool's definition Tool name 'get_commit_refs' uses the verb 'get', which indicates data retrieval. The empty description limits certainty, but the naming pattern is consistent with read-only operations that query Git references (branches, tags) associated with a commit.
Attacks that exploit this kind of access
get_commit_refs. It is categorised as a Read tool in the Kepler MCP GitLab Server MCP Server, which means it retrieves data without modifying state.
Register the Kepler MCP GitLab Server MCP server in PolicyLayer and add a rule for get_commit_refs: 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 Kepler MCP GitLab Server. Nothing to install.
get_commit_refs 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_refs 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_refs. 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_refs is provided by the Kepler MCP GitLab Server MCP server (ryan-rbw/kepler-mcp-gitlab-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
