mcp-gitlab GEMINI.md

A set of instructions for an MCP server that connects a coding agent to GitLab, a platform for hosting code and managing software projects. It covers projects, merge requests, reviews, pipelines, releases, branches, commits, variables, issues, and groups.

In plain words
What is it for?
Creating and managing projects, branches, commits, merge requests, reviews, CI/CD pipelines and jobs, releases, issues, groups, and project settings.
Why use it?
It helps the agent work with GitLab's development workflow from one place instead of switching between many GitLab pages or commands.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-gitlab GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

mcp-gitlab — Gemini CLI Extension Context

MCP server providing 83 tools, 7 resources, and 6 prompts for interacting with the GitLab API. Covers the full lifecycle of GitLab projects: code, reviews, CI/CD, releases, and issue tracking.

Tool Categories

  • Projects — get, create, delete, update merge settings, share/unshare with groups
  • Merge Requests — list, get, create, update, merge, rebase, view changes and diffs, approve, unapprove, get approvals, list pipelines, list commits, subscribe, unsubscribe
  • MR Reviews — list/add/update/delete notes, list/create discussions, reply to and resolve discussions, award/remove emoji
  • MR Approvals — project-level and MR-level approval rules (list, create, update, delete)
  • Pipelines & Jobs — list/get/create/retry/cancel pipelines, retry/play/cancel jobs, get job logs
  • Branches — list, create, delete
  • Commits — list, get, create, compare refs
  • Tags & Releases — list/get/create/delete tags, list/get/create/update/delete releases
  • CI/CD Variables — project and group variables (list, create, update, delete)
  • Issues — list, get, create, update, add comments
  • Groups — list, get, share/unshare groups

Common Workflows

  • Code review: list_mrs -> mr_changes -> list_mr_discussions -> add_mr_note or create_mr_discussion -> resolve_discussion
  • Pipeline debugging: list_pipelines -> get_pipeline -> get_job_log -> retry_job
  • Release process: list_commits -> compare -> create_tag -> create_release
  • Branch protection: list_project_approval_rules -> create_project_approval_rule -> update_project_merge_settings
  • Issue triage: list_issues -> get_issue -> update_issue -> add_issue_comment

Notes

  • Set GITLAB_READ_ONLY=true to restrict all operations to read-only (no writes, no deletes).
  • Token requires appropriate GitLab scopes: api for full access, read_api for read-only.
  • Default request timeout is 30 seconds; override with GITLAB_TIMEOUT.
  • SSL verification is on by default; disable with GITLAB_SSL_VERIFY=false for self-signed certs.
  • Works with GitLab.com and self-hosted GitLab instances.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
