[ MCP SERVER SUMMARY ]
GitLab MCP server summary
GitLab’s official MCP server lets AI tools access project data, manage issues, and perform repository operations with OAuth 2.0. Bifrost handles upstream OAuth token refresh, scopes tool access per virtual key, and records an immutable audit trail for compliance.
| Property | Details |
|---|---|
| Company | GitLab |
| Connection type | HTTP |
| Authentication | OAuth 2.0 |
| Package or endpoint | Your GitLab instance MCP endpoint |
| Capabilities | Project and repository access, Issue management, OAuth-based user access |
| Official documentation | GitLab MCP documentation |
Before you start
- A GitLab account with MCP access
- OAuth application credentials
What you can do with GitLab
- Connect Claude Code or Cursor to GitLab repos without embedding OAuth tokens in every client config
- Separate production and staging GitLab access with different virtual keys and tool policies
- Meet enterprise audit requirements with logged GitLab tool calls tied to user and team identity
[ HOW TO CONNECT ]
Connect GitLab to Bifrost in three steps
Install Bifrost
Start the gateway locally or deploy in your VPC.
npx -y @maximhq/bifrost
Add GitLab in MCP Gateway
Open MCP Gateway in the Bifrost dashboard, click New MCP Server, and choose HTTP. Or register via the API below.
• GitLab MCP typically uses OAuth — set Auth Type to oauth or per_user_oauth in Bifrost.
• For shared service accounts, header auth with a project access token may be simpler.
Point clients at Bifrost /mcp
Configure Claude Desktop, Cursor, or Claude Code to use your Bifrost endpoint with a virtual key instead of connecting directly to GitLab.

}[ EXAMPLE CONFIG ]
Register GitLab via API
Add this MCP client with a POST to /api/mcp/client. See Connecting to MCP Servers for full options.
curl -X POST http://localhost:8080/api/mcp/client \

}'[ WHY BIFROST ]
Run GitLab through one governed gateway
Access control
Virtual keys, RBAC, and tool allowlists per team or agent.
Cost governance
Attribute MCP tool spend alongside LLM usage in one view.
Observability
Log every tool call with latency, server, and virtual key metadata.
Credential isolation
Upstream secrets stay in the gateway — not on every laptop.
[ FAQ ]
Common questions
Does GitLab MCP require OAuth?
GitLab’s official MCP server is designed for OAuth 2.0. Bifrost supports oauth and per_user_oauth auth types and handles token refresh for upstream HTTP MCP servers.
Can I use GitLab.com and self-managed GitLab?
Yes. Set connection_string to your GitLab instance MCP endpoint — gitlab.com or your private hostname — and configure OAuth against that instance.
How do agents discover GitLab tools through Bifrost?
After the MCP client is registered, external clients call Bifrost’s /mcp endpoint. Bifrost aggregates GitLab tools alongside any other connected servers for that virtual key.
