@coro-ai/plugin-gitlab

Reference Coro plugin for GitLab. Operates in MCP mode: day-to-day SCM operations (creating MRs, posting comments, merging) are served by the upstream @modelcontextprotocol/server-gitlab package which Coro spawns once per job. The plugin itself only owns the four operations that have no MCP equivalent:

• cloneInfo — credentialed HTTPS clone URLs
• matchesRemote — host detection for self-improvement PRs
• normalizeInbound — webhook → NormalizedEvent
• pollPr — REST polling outside query() sessions
• writerCreatePr — escape hatch used by the self-improvement writer

It is published as a working example for plugin authors. The same shape is used by every published Coro plugin.

Install

coro plugin install @coro-ai/plugin-gitlab

Then configure under plugins.installed.gitlab in ~/.coro/config.json:

{
  "plugins": {
    "installed": {
      "gitlab": {
        "enabled": true,
        "config": {
          "namespace": "my-group",
          "token": "glpat-…",
          "baseUrl": "https://gitlab.example.com/api/v4"
        }
      }
    }
  }
}

baseUrl is optional — omit for gitlab.com. The token needs the api and read_repository scopes.

Restart coro start so the runner picks up the new plugin.

Architecture

agent ──► mcp__gitlab__create_merge_request   ─┐
agent ──► scm_create_pr (proxy)               ─┤── upstream MCP server
                                                │   (npx @modelcontextprotocol/server-gitlab)
runner   normalizeInbound (webhook bridge)
runner   pollPr             (timer poller)      ── direct REST
runner   writerCreatePr     (writer)            ── direct REST
runner   cloneInfo          (clone helper)      ── pure local

The agent always prefers the trimmed scm_* proxy or the direct mcp__gitlab__* tools. The plugin's REST calls are reserved for operations that run outside any active query() session.
