## 🚀 Getting Started
### Installation
#### From npm (Recommended)
```bash
npm install @yoda.digital/gitlab-mcp-server
```
#### From Source
```bash
# Clone the repository
git clone https://github.com/yoda-digital/mcp-gitlab-server.git
cd mcp-gitlab-server
# Install dependencies
npm install
# Build the project
npm run build
```
### Configuration
#### Environment Variables
The server requires the following environment variables:
| Variable | Required | Default | Description |
| ------------------------------ | -------- | --------------------------- | -------------------------------------------------- |
| `GITLAB_PERSONAL_ACCESS_TOKEN` | Yes | - | Your GitLab personal access token |
| `GITLAB_API_URL` | No | `https://gitlab.com/api/v4` | GitLab API URL |
| `PORT` | No | `3000` | Port for SSE transport |
| `USE_SSE` | No | `false` | Set to 'true' to use SSE transport |
| `GITLAB_READ_ONLY_MODE` | No | `false` | Set to 'true' to enable read-only mode (see below) |
#### Read-Only Mode
When `GITLAB_READ_ONLY_MODE` is set to `true`, the server will only expose read operations. This is useful for client applications that shouldn't have write access to your GitLab resources. In read-only mode, the following tools will be available:
- `search_repositories`
- `get_file_contents`
- `list_group_projects`
- `get_project_events`
- `list_commits`
- `list_issues`
- `list_merge_requests`
- `list_project_wiki_pages`
- `get_project_wiki_page`
- `list_group_wiki_pages`
- `get_group_wiki_page`
- `list_project_members`
- `list_group_members`
Any attempt to use write operations (create, update, delete) will result in an error when in read-only mode.
#### MCP Settings Configuration
Add the GitLab MCP server to your MCP settings file:
```json
{
"mcpServers": {
"gitlab": {
"command": "npx",
"args": ["-y", "@yoda.digital/gitlab-mcp-server"],
"env": {
"GITLAB_PERSONAL_ACCESS_TOKEN": "your_token_here",
"GITLAB_API_URL": "https://gitlab.com/api/v4"
},
"alwaysAllow": [],
"disabled": false
}
}
}
```
For read-only mode, add the `GITLAB_READ_ONLY_MODE` environment variable:
```json
{
"mcpServers": {
"gitlab-readonly": {
"command": "npx",
"args": ["-y", "@yoda.digital/gitlab-mcp-server"],
"env": {
"GITLAB_PERSONAL_ACCESS_TOKEN": "your_token_here",
"GITLAB_API_URL": "https://gitlab.com/api/v4",
"GITLAB_READ_ONLY_MODE": "true"
},
"alwaysAllow": [],
"disabled": false
}
}
}
```
### Usage
#### With stdio transport (default)
```bash
# Set your GitLab personal access token
export GITLAB_PERSONAL_ACCESS_TOKEN=your_token_here
# Run the server
npm start
```
#### With SSE transport
```bash
# Set your GitLab personal access token and enable SSE
export GITLAB_PERSONAL_ACCESS_TOKEN=your_token_here
export GITLAB_READ_ONLY_MODE=false
export USE_SSE=true
export PORT=3000 # Optional, defaults to 3000
# Run the server
npm start
```
#### With npx
```bash
# Run directly with npx
GITLAB_PERSONAL_ACCESS_TOKEN=your_token_here npx @yoda.digital/gitlab-mcp-server
```
