qodev-gitlab-api 0.2.2

Python client for the GitLab API

qodev-gitlab-api

A lightweight, typed Python client for the GitLab REST API. Built on httpx with automatic pagination, structured error handling, and .env support, it provides a clean interface for common GitLab operations without the weight of a full-featured SDK.

Why this library?

• Lightweight -- just httpx, no heavy ORM-like abstractions
• Typed -- ships with py.typed for full mypy/pyright support
• Agent-friendly -- simple method signatures, dict returns, auto-pagination
• Built for tools -- designed for MCP servers and CLIs, not full application frameworks
• Focused -- python-gitlab is comprehensive but heavy; this library covers the operations AI agents and developer tools actually need

Installation

pip install qodev-gitlab-api

Quick Start

from qodev_gitlab_api import GitLabClient

# Reads GITLAB_TOKEN and GITLAB_URL from environment or .env file
client = GitLabClient()

# Or pass credentials explicitly
client = GitLabClient(token="glpat-xxxxxxxxxxxx", base_url="https://gitlab.example.com")

# Skip connection validation for faster startup
client = GitLabClient(validate=False)

# List open merge requests
mrs = client.get_merge_requests("mygroup/myproject", state="opened")
for mr in mrs:
    print(f"!{mr['iid']} {mr['title']}")

# Create a merge request
client.create_merge_request("mygroup/myproject", "feature-branch", "main", "Add new feature")

# Get pipeline status
pipelines = client.get_pipelines("mygroup/myproject")

Features

• Merge requests -- create, update, merge, close, and review with inline diff comments
• Pipelines and jobs -- list, inspect, wait for completion, retry, and download artifacts
• Issues -- create, update, close, and comment
• Releases -- create, update, delete, and list with asset links
• CI/CD variables -- get, list, create, update, and upsert (set) project variables
• File operations -- read repository files at any ref, upload files for markdown embedding
• Automatic pagination -- all list endpoints handle multi-page results transparently
• Typed exceptions -- AuthenticationError, NotFoundError, APIError, ConfigurationError

Configuration

The client reads configuration from environment variables, with .env file support via python-dotenv:

Variable	Description	Default
GITLAB_TOKEN	GitLab personal access token (required)	--
GITLAB_URL	GitLab instance base URL	https://gitlab.com

You can also use GITLAB_BASE_URL as an alias for GITLAB_URL.

Create a .env file in your project root:

GITLAB_TOKEN=glpat-xxxxxxxxxxxxxxxxxxxx
GITLAB_URL=https://gitlab.example.com

File Operations

# Read a file from the repository

Error Handling

All API errors raise typed exceptions that inherit from GitLabError:

from qodev_gitlab_api import GitLabClient, AuthenticationError, NotFoundError, APIError, ConfigurationError

try:
    client = GitLabClient()
    mr = client.get_merge_request("my-group/my-project", mr_iid=999)
except ConfigurationError:
    print("Missing or invalid GITLAB_TOKEN / GITLAB_URL")
except AuthenticationError:
    print("Token is invalid or expired")
except NotFoundError:
    print("Merge request not found")
except APIError as e:
    print(f"API error {e.status_code}: {e.response_body}")
