MOST DANGEROUS TOOLS

High Risk

The most dangerous GitLab Review MCP tools

Write · Medium add_review_comment This tool creates new comments on pull requests, which modifies repository state reversibly. Write · High create_merge_request Creating a merge request is a reversible write operation—it creates a code review artifact that can be closed or deleted, but it commits code changes to the repository and triggers CI/CD pipelines and reviewer notificati

2 of GitLab Review MCP's 15 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control GitLab Review MCP

PolicyLayer is an MCP gateway — it sits between your AI agents and GitLab Review MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "add_review_comment": {
    "limits": [
      {
        "counter": "add_review_comment_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "analyze_code_quality": {
    "limits": [
      {
        "counter": "analyze_code_quality_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
