GitLab MCP Source control

Projects, merge requests, issues, CI/CD pipelines and job logs on GitLab.com or self-managed GitLab.

1 credits / tool call

Quick start

Add a GitLab connection with the settings below, then click Test configuration.
Create an API key for your agent.
Paste the key below, click Test endpoint, and copy the configuration for your platform.

Endpoint	`https://market.oshaani.com/gitlab` (your default connection) or `https://market.oshaani.com/gitlab/<connection-id>`
Transport	Streamable HTTP (stateless, JSON responses). MCP protocol versions 2024-11-05 to 2025-11-25 and 2026-07-28.
Authentication	`Authorization: Bearer <API key>`, using a key from the API keys page.

Agent configuration

Endpoint The default URL uses your organisation's default GitLab connection; a URL with an ID pins one connection.

API key

Get a key

The key is filled into the snippets below. It stays in this page and is only sent with the test request.

Runs initialize and tools/list against the endpoint, exactly like an agent. No credits are charged.

Any MCP client that supports remote (Streamable HTTP) servers with custom headers.

{
  "name": "gitlab",
  "transport": "streamable-http",
  "url": "https://market.oshaani.com/gitlab",
  "headers": {
    "Authorization": "Bearer YOUR_API_KEY"
  }
}

~/.cursor/mcp.json (all projects) or .cursor/mcp.json in a project.

{
  "mcpServers": {
    "gitlab": {
      "url": "https://market.oshaani.com/gitlab",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Settings > Developer > Edit Config (claude_desktop_config.json). Uses the mcp-remote bridge; needs Node.js.

      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "AUTH_HEADER": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Run in your terminal, or put the JSON in .mcp.json at the project root.

claude mcp add --transport http gitlab https://market.oshaani.com/gitlab \

Responses API remote MCP tool (Python SDK).

Messages API MCP connector (Python SDK).

Official MCP Python SDK 2.x (pip install mcp); works inside any agent framework.

import asyncio

from mcp import ClientSession
from mcp.client.streamable_http import create_mcp_http_client, streamable_http_client


async def main():
    headers = {"Authorization": "Bearer YOUR_API_KEY"}
    async with create_mcp_http_client(headers=headers) as http:
        async with streamable_http_client("https://market.oshaani.com/gitlab", http_client=http) as (read, write, *_):
            async with ClientSession(read, write) as session:
                await session.initialize()
                tools = await session.list_tools()
                print([tool.name for tool in tools.tools])


asyncio.run(main())

Quick check from a terminal: lists the tools without charging credits.

Billing & errors

Each successful tool call costs 1 oshaani.com credit. initialize, tools/list, failed calls and timeouts are free.

JSON-RPC code	Meaning
`-32054` (HTTP 401)	Missing, unknown or revoked API key
`-32053` (HTTP 404)	No GitLab connection configured for your organisation, or the connection ID is wrong
`-32055` (HTTP 403)	Connection disabled or origin not allowed
`-32052` (HTTP 429)	Rate limit reached; retry after a minute
`-32050`	Not enough oshaani.com credits for the call
`-32051`	Billing temporarily unavailable; the call was not run

Errors from GitLab itself (bad IDs, permissions) come back as tool results with isError: true so the agent can read and correct them. See the GitLab API documentation.
