GitLab's API is well-documented and accessible, making it a reasonable target for an OpenClaw integration. Teams want their AI assistant to answer questions about merge requests, pipelines, and issues without switching to the GitLab UI.
How OpenClaw Integrations Work
OpenClaw is a self-hosted AI assistant that runs on your own server — typically an EC2 instance — and connects to Slack. It uses Claude under the hood to process requests. Out of the box, OpenClaw doesn't ship with pre-built connections to third-party tools. Instead, integrations are built using the skills system: markdown files in ~/.openclaw/skills/ that give Claude instructions for a particular domain, combined with HTTP tool calls to any API you expose to it.
In practice, adding a real integration means: getting API credentials from the third-party service, building or configuring a small proxy/endpoint that OpenClaw can call, and writing a skill file that tells Claude how to use it. For some tools this is an afternoon of work. For others — like GitLab — it's considerably more involved.
Connecting OpenClaw with GitLab: Step by Step
Step 1: Generate a GitLab Personal Access Token
Go to GitLab → User Settings → Access Tokens. Create a token with api scope for full access, or read_api for read-only. If you're on GitLab.com, the base URL for the API is https://gitlab.com/api/v4. Self-hosted GitLab instances have their own base URL.
Step 2: Build a Proxy Service
Write a small service that stores your token and exposes endpoints OpenClaw can call — e.g., GET /gitlab/mr?id=204&project=myorg/myrepo. The GitLab REST API uses project IDs or URL-encoded namespaces, so your proxy should handle that translation to keep the skill file clean.
Step 3: Write the Skill File
Create ~/.openclaw/skills/gitlab.md documenting what GitLab data is available and how to query it. Include the project identifiers your team uses most frequently so Claude doesn't have to guess.
Challenges and Caveats
Self-Hosted vs GitLab.com
If your team runs GitLab self-hosted, network access from your EC2 instance to your GitLab server needs to be explicitly allowed. Check your firewall rules and consider whether you're comfortable with the EC2 instance having network access to your internal GitLab.
Project IDs vs Namespaces
GitLab's API accepts both numeric project IDs and URL-encoded namespace paths. Using numeric IDs is more reliable but less readable in skill files. Worth standardising early.
