Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks. This guide walks you through the easiest and most secure way to connect your Gitlab account to Cowork via Composio Connect, enabling it to create new GitLab group for QA team, open bug issue in frontend project, create branch from latest main commit, and more such actions on your behalf without compromising your account security. ## Also integrate Gitlab with - [ChatGPT](https://composio.dev/toolkits/gitlab/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/gitlab/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/gitlab/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/gitlab/framework/claude-code) - [Codex](https://composio.dev/toolkits/gitlab/framework/codex) - [Cursor](https://composio.dev/toolkits/gitlab/framework/cursor) - [VS Code](https://composio.dev/toolkits/gitlab/framework/vscode) - [OpenCode](https://composio.dev/toolkits/gitlab/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/gitlab/framework/openclaw) - [Hermes](https://composio.dev/toolkits/gitlab/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/gitlab/framework/cli) - [Google ADK](https://composio.dev/toolkits/gitlab/framework/google-adk) - [LangChain](https://composio.dev/toolkits/gitlab/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/gitlab/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/gitlab/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/gitlab/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/gitlab/framework/crew-ai) ## Connect Gitlab to Claude Cowork ### Connecting Gitlab to Claude Cowork 1. Open Customize In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. 2. Add the Composio MCP server Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is Claude Cowork? Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools. With Composio Connect, Cowork can securely access apps like Gitlab through MCP without you sharing account credentials directly with the agent. ## What is the Gitlab MCP server, and what's possible with it? The Gitlab MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gitlab account. It provides structured and secure access to your repositories, projects, and issues, so your agent can perform actions like creating projects, managing issues, handling branches, and automating DevOps workflows on your behalf. - Project and group automation: Instantly create new Gitlab projects or organize your workspaces by setting up project groups—all without manual clicks. - Issue creation and tracking: Have your agent report bugs, request features, or open new issues in specific projects to keep your team on top of tasks. - Branch management: Let your agent create repository branches from any commit or base branch, making it easy to streamline your development process. - Project lifecycle management: Archive completed projects or delete unneeded ones, keeping your workspace clean and up to date with minimal effort. - Commit and job insights: Retrieve commit references, determine commit sequence in project history, or erase job artifacts and logs for deeper CI/CD control. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `GITLAB_ARCHIVE_PROJECT` | Archive Project | Tool to archive a project.

With a standalone Gitlab MCP server, the agents and LLMs can only access a fixed set of Gitlab tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Gitlab and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Claude Cowork? Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Gitlab tools. ### Can I manage the permissions and scopes for Gitlab while using Tool Router? Yes, absolutely. You can configure which Gitlab scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Gitlab data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
