WHAT IT DOES

What create_commit_status does on Gitlab Mcp

AI agents use create_commit_status to create or update resources in Gitlab Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gitlab Mcp environment.

RISK

Why create_commit_status is rated Medium

Creating or updating a commit status is a write operation that changes CI/CD pipeline state or build status information. While reversible (status can be updated again), it can affect visibility, gating, or downstream pipeline decisions. Not destructive (doesn't delete data), not execute (doesn't run code directly), not financial.

From the tool's definition Tool description states 'Create or update the status of a commit' — this is a write operation that modifies commit metadata (status) reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_commit_status safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gitlab Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_commit_status, this is the rule to start with:

create_commit_status Rate-limited

create_commit_status stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab Mcp, apply this rule, and every create_commit_status call is checked against it from then on.
