Gitlab server - Invalid arguments

[umairatwork8]

Issue Description

When attempting to interact with GitLab's API through the integration, multiple operations are failing with argument validation errors.

Steps to Reproduce

1. Attempted to create a new repository: Error: MCP error -32603: Invalid arguments: fork: Required
2. Attempted to search existing repositories:
   Error: MCP error -32603: Invalid arguments: items.0.owner: Required, items.0.fork: Required, items.1.fork: Required, items.2.owner: Required, items.2.fork: Required [...]

Expected Behavior

• Repository creation should process with basic parameters (name, visibility, description)
• Repository search should return results without requiring owner and fork parameters for each item

Actual Behavior

The API is requiring additional parameters that seem to be internal GitLab properties:

• fork parameter is required for repository creation
• owner and fork parameters are required for each item in search results

Impact

This issue prevents basic GitLab operations from working, including:

• Repository creation
• Repository search
• Potentially other GitLab API integrations

I'm having this problem as well.

me too mcp api is wrong

same problem for search repo in gitlab by name

[TomskDiver]

The fact is that in Gitlab v. 16 REST API there are no fork and owner attributes for the repository object.

Gitlab MCP is completely unusable for self-host Gitlab because of this bug.

I am experiencing this bug on the public SaaS GitLab.com as well. MCP is unusable.

#721 was merged with the fix.

Hi @francovp , how do I use the latest version of this MCP server? My cursor IDE still returned the "Invalid arguments" error.

@flyisland - Looks like there are experimental builds available on docker hub. If you're feeling risky, you can reference the development docker image tag mcp/gitlab:edge in your config until an official release is cut.

{
  "mcpServers": {
    "gitlab": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "GITLAB_PERSONAL_ACCESS_TOKEN",
        "-e",
        "GITLAB_API_URL",
        "mcp/gitlab:edge"
      ],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "your-token",
        "GITLAB_API_URL": "https://gitlab.com/api/v4"
      }
    }
  }
}

I was able to get my gitlab connection working with this change and will revert to the release image in a few weeks once the changes make it through.

Thanks for reporting this. This server has been moved to the archived repository at https://github.com/modelcontextprotocol/servers-archived to reduce maintenance overhead, so we can focus our efforts on a smaller set of core servers.
Since this server is no longer actively maintained, we recommend checking out the alternatives listed in the Readme.
