What gitlab_list_commits does on Sage MCP
AI agents call gitlab_list_commits to retrieve information from Sage MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why gitlab_list_commits is rated Low
This tool queries and returns a list of commits from a GitLab repository. It performs no modifications, deletions, or external operations—purely data retrieval. The blast radius of misuse is minimal; an agent could only access commit history metadata that is typically visible to authorized users. This is a standard Read operation.
From the tool's definition Tool name 'gitlab_list_commits' and description 'List repository commits' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
The rule that runs gitlab_list_commits safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sage MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gitlab_list_commits, this is the rule to start with:
gitlab_list_commits is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Sage MCP, apply this rule, and every gitlab_list_commits call is checked against it from then on.
Questions about gitlab_list_commits
List repository commits. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for gitlab_list_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 Sage MCP. Nothing to install.
gitlab_list_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 gitlab_list_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 gitlab_list_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.
gitlab_list_commits is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
