Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account sumirati for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local GitLab MCP server that lets an assistant read and manage projects, branches, commits, merge requests, issues and CI/CD pipelines on GitLab.com or self‑h

What you can do: Discover and run GitLab operations across 14 domains through a small hybrid tool surface, with optional exposure of all 90 actions directly. Read repositories: file contents, directory trees, project metadata, branches, commits and diffs. Manage repositories and branches: create, update, fork and delete projects, create and delete branches, and set branch protection. Work with merge requests, issues, milestones, labels, wikis and snippets, including diff discussions and issue notes. Inspect and control CI/CD: list, trigger, cancel and retry pipelines, read job logs, artifacts and JUnit test reports, and manage project CI/CD variables. Check instance health, runners, push mirrors and webhooks
When to use it: Useful when an assistant should work with a GitLab instance without cloning: reviewing merge requests and diffs, checking pipeline failures and job logs, reading source files, or making commits and branch changes through the API. A read-only mode suits inspection-only setups.
Requirements: Runs locally via npx or a global npm install, so Node.js is needed. Requires a GitLab personal access token with api scope in GITLAB_PERSONAL_ACCESS_TOKEN, and network access to the GitLab instance. GITLAB_API_URL points at a self-hosted CE/EE instance and defaults to GitLab.com.

Before you install

The token grants broad api-scope access to the GitLab account. Many actions write or delete: creating and deleting projects and branches, committing files, changing branch protection, triggering, cancelling or retrying pipelines, and creating, updating or deleting CI/CD variables. Deleting a project is irreversible and requires name confirmation. Read-only mode is off by default; set GITLAB_READ_ONLY to block writes. Variable reads can expose secret values.

Installation

In SourceWeft

Open GitLab MCP Server in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

GitLab MCP Server (`@sumirati/mcp-gitlab`)

A modern, 2026 AI-native Model Context Protocol (MCP) server for GitLab API v4, engineered for self-hosted GitLab Community Edition (CE), Enterprise Edition (EE), and GitLab.com.

[npm version] [License: MIT] [GitHub] [GitLab]

What makes v3.0.0 Unique: The 2026 5-Tool Hybrid Standard

In early MCP servers, dumping 50–100 tools into the client's tool list consumed 10,000+ prompt context tokens on every turn ("System Prompt Tax") and resulted in poor Coherence ratings on the Glama TDQS rubric.

@sumirati/mcp-gitlab v3 solves this with a 5-Tool Hybrid Surface:

Glama TDQS Coherence Tier A (5/5): By exposing exactly 5 tools to the client, the server sits in the ideal 3–15 tool coherence sweet spot.
Ultra-Lean System Prompt Tax: Drops schema overhead from 27,681 tokens to 1,292 tokens (95.3% reduction), preserving context windows and maximizing LLM prompt-cache hits.
Zero-Hop Hourly Drivers: The 3 operations developers and agents actually use constantly during pair-programming (get_file_contents, get_project, get_commit) remain eager tools for instant zero-hop execution.
100% Platform Access on Demand: The entire platform surface of 90 actions across 14 domains is accessible on-demand via dynamic action discovery (gitlab_find_actions $\rightarrow$ gitlab_execute_action), delivering 75%–96% token savings with default high-density Markdown tables and summaries (format: "markdown" | "json").
Resilient Fallback: If an agent directly invokes any catalog action name (e.g. list_pipelines), the server dynamically executes it with full input validation and projection.

Benchmarks: Token Economy in Action

Reproducible deterministic benchmark (node test/benchmark-test.js & node test/catalog-execution-test.js) measured against canonical GitLab REST API v4 payloads (test/fixtures/gitlab-api-v4-fixtures.js, token count = Math.ceil(utf8Bytes / 4)):

Operation	Raw GitLab API v4	`@sumirati/mcp-gitlab` (JSON)	`@sumirati/mcp-gitlab` (Markdown)	Token Reduction (MD)
System Prompt Tax (5 tools vs 90 actions)	27,681 tokens	—	1,292 tokens	95.3% savings
`get_project` (Single project inspect)	971 tokens	144 tokens	124 tokens	87.2% savings
`list_issues` (10 issues with v4 metadata)	6,595 tokens	1,906 tokens	460 tokens	93.0% savings
`list_merge_requests` (10 MRs with v4 metadata)	6,377 tokens	1,058 tokens	423 tokens	93.4% savings
`list_pipelines` (10 runs)	880 tokens	543 tokens	212 tokens	75.9% savings
`get_file_contents` (Source file, Base64 stripped)	279 tokens	201 tokens	160 tokens	42.7% savings
`get_merge_request_changes` (Code + lockfile diff)	3,612 tokens	156 tokens	141 tokens	96.1% savings

Complete 90-Action Catalog Benchmark (Across All 14 Domains)

Measured across all 90 handlers via node test/catalog-execution-test.js:

Domain	Actions	Raw GitLab v4 Tokens	Projected JSON	Rendered Markdown	Token Savings (MD)
repositories	10	8,966 tokens	1,361 tokens	728 tokens	91.9%

TOTAL (All 90 Actions)	90	429,710 tokens	13,115 tokens	5,960 tokens	98.6%

Key Token Optimization Pillars:

Smart Diff & Lockfile Truncation: Commit diffs (get_commit) and MR changes (get_merge_request_changes) automatically collapse dependency lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, go.sum, Cargo.lock, *.min.js) via ignore_lockfiles: true by default, saving 1,000–3,000 tokens per review. Pass ignore_lockfiles: false if full lockfile diffs are required.
Conservative Default Pagination: All list actions default to per_page: 10 (max: 100), eliminating token waste from loading 20–50 items when only recent entries are needed.
Default High-Density Markdown Format: Discovery (gitlab_find_actions), execution (gitlab_execute_action), project info (get_project), file inspection (get_file_contents), and commit inspection (get_commit) default to format: "markdown", yielding 75%–96% token reductions for structured metadata.
Recursive Output Projection Filter (projectOutput): Strips GitLab REST API v4 noise metadata keys (_links, avatar_url, references, time_stats, task_completion_status, commands_changes, user_notes_count, merge_requests_count, upvotes, downvotes, subscribed, has_tasks, service_desk_reply_to, moved_to_id, container_expiration_policy, permissions, and null/empty fields) before payloads reach LLM context.

Roadmap

Upcoming (v3.2)

Upstream indexed filtering & strict pagination caps (state, labels, milestone, author_id, assignee_id)
Client error resilience (401 probe disambiguation, 403 insufficient scope, 429 rate limit backoff, 201 ghost write guard)
Hardened output projection with recursion depth guard (maxDepth = 32) and empty collection preservation
Nested subgroup hierarchy management (create_group with parent_id)
Smart CI/CD failure log extraction & ANSI sequence stripping in get_job_trace (strip_ansi, smart_failure)
Outline-first code symbol extraction & line range slicing in get_file_contents (outline_only, start_line, end_line)
Pre-flight mergeability & conflict verification (get_mergeability)
Token scope self-auditing & permission pre-flight

Future Horizons (v3.x)

Standardized collection _summary headers to facilitate multi-turn history pruning in LiteLLM / Eigent agent orchestration
Remote Transports: Streamable SSE and HTTP remote server modes
Scoped GraphQL query engine for relational deep inspections
DevSecOps vulnerability & secret scanning alert queries
Scoped & rate-guarded code search within project repositories
