GitLab MCP — wraps the GitLab REST API v4 (BYO API key)

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

Tool

Description

gitlab_list_projects

List all accessible GitLab projects. Returns project ID, name, path, description, star count, and URL. Use gitlab_get_project to fetch detailed info.

gitlab_get_project

Get details for a specific GitLab project (e.g., project ID "123" or path "group/project"). Returns name, description, visibility, stars, forks, and default branch.

gitlab_list_issues

Search issues in a GitLab project by project ID. Returns issue ID, title, state (open/closed), labels, assignee, and URL. Filter by status and labels.

gitlab_list_mrs

List merge requests in a GitLab project by project ID. Returns MR ID, title, state, author, source/target branches, and URL. Filter by state and author.

gitlab_get_file

Fetch file content from a GitLab repository by project ID and file path (e.g., "src/main.py"). Returns decoded content, file size, name, and encoding.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "gitlab": {
      "url": "https://gateway.pipeworx.io/gitlab/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/gitlab/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Gitlab data" })

The gateway picks the right tool and fills the arguments automatically.

No MCP client? Call it over HTTP

This pack takes your own API key (_apiKey) — we don't front one for it, so there's no curl here that would run without it. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/gitlab_list_projects. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
