# create_group_milestone Create a new group milestone Agent View of the PolicyLayer registry record for `create_group_milestone`. HTML page: https://policylayer.com/tools/io-github-zereight-gitlab-mcp/create-group-milestone ## Facts - Tool: `create_group_milestone` - Server: Gitlab Mcp (`@zereight/mcp-gitlab`) — https://policylayer.com/tools/io-github-zereight-gitlab-mcp.md - Install: `npx -y @zereight/mcp-gitlab` - Homepage: https://github.com/zereight/gitlab-mcp - Risk category: Write (Medium 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": "create_group_milestone", "arguments": {} } } ``` ## Why create_group_milestone is rated Medium This tool creates a new milestone object in GitLab, which is reversible (milestones can be edited or deleted). It modifies project/group data by adding a new milestone, but does not execute code, delete data irreversibly, or move money. The blast radius is medium because creating milestones affects project tracking and timeline planning, but malicious creation of spurious milestones can be remediated. From the tool's own definition: "Tool name 'create_group_milestone' and description 'Create a new group milestone' indicate creation of a new entity within GitLab's project management system." ## Use case AI agents use create_group_milestone 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Gitlab Mcp: ```json { "version": "1", "default": "deny", "tools": { "create_group_milestone": { "limits": [ { "counter": "create_group_milestone_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Gitlab Mcp (240) - `cancel_pipeline_job` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/cancel-pipeline-job.md - `delete_branch` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-branch.md - `delete_draft_note` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-draft-note.md - `delete_group_milestone` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-group-milestone.md - `delete_group_variable` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-group-variable.md - `delete_group_wiki_page` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-group-wiki-page.md - `delete_issue` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-issue.md - `delete_issue_emoji_reaction` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-issue-emoji-reaction.md - `delete_issue_link` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-issue-link.md - `delete_issue_note_emoji_reaction` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-issue-note-emoji-reaction.md - `delete_label` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-label.md - `delete_merge_request_discussion_note` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-merge-request-discussion-note.md - `delete_merge_request_emoji_reaction` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-merge-request-emoji-reaction.md - `delete_merge_request_note` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-merge-request-note.md - `delete_merge_request_note_emoji_reaction` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-merge-request-note-emoji-reaction.md - `delete_milestone` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-milestone.md - `delete_pipeline_schedule` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-pipeline-schedule.md - `delete_pipeline_schedule_variable` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-pipeline-schedule-variable.md - `delete_project_variable` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-project-variable.md - `delete_release` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-release.md - `delete_tag` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-tag.md - `delete_wiki_page` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-wiki-page.md - `delete_work_item_emoji_reaction` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-work-item-emoji-reaction.md - `delete_work_item_note_emoji_reaction` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/delete-work-item-note-emoji-reaction.md - `omg_clear_state` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/omg-clear-state.md - `omg_delete_memory` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/omg-delete-memory.md - `purge_dependency_proxy_cache` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/purge-dependency-proxy-cache.md - `unprotect_branch` — Destructive — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/unprotect-branch.md - `cancel_pipeline` — Execute — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/cancel-pipeline.md - `create_pipeline` — Execute — https://policylayer.com/tools/io-github-zereight-gitlab-mcp/create-pipeline.md - …and 210 more: https://policylayer.com/tools/io-github-zereight-gitlab-mcp.md ## For agents This record is a snapshot.
