## Facts

- Tool: `gitlab_trigger_pipeline`
- Server: Gitlab (`dkeeno/gitlab-mcp-server`) — https://policylayer.com/tools/dkeeno-gitlab-mcp-server.md
- Homepage: https://github.com/dkeeno/gitlab-mcp-server
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "gitlab_trigger_pipeline",
    "arguments": {}
  }
}
```

## Why gitlab_trigger_pipeline is rated High

Triggering a CI/CD pipeline executes external operations (builds, tests, deployments) whose consequences are determined by the pipeline's configuration and cannot be easily predicted or reversed without additional actions. This is Execute rather than Write because it runs code/workflows rather than simply creating data.

From the tool's own definition: "Tool description states 'Trigger a GitLab CI/CD pipeline on a branch' — this initiates automated workflow execution whose effects depend on pipeline configuration and may include deployments, code execution, and infrastructure changes."

## Use case

AI agents invoke gitlab_trigger_pipeline to trigger actions in Gitlab. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Gitlab:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "gitlab_trigger_pipeline": {
      "limits": [
        {
          "counter": "gitlab_trigger_pipeline_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
