• Zammad API Token: An API token generated within your Zammad instance with sufficient permissions.

Getting a Zammad API Token

You need to generate an API token within Zammad to allow this MCP server to authenticate and interact with the API.

1. Log in to your Zammad instance with an administrator account (or an account that has permission to manage API tokens).
2. Navigate to your Profile settings (usually by clicking your avatar/initials in the bottom-left).
3. Go to the Token Access section.
4. Click "Create" or the relevant button to generate a new token.
5. Give the token a descriptive Label (e.g., "Claude MCP Server").
6. Crucially, assign the necessary permissions. Based on the tools provided, you will likely need permissions like:
   • ticket.agent (or ticket.customer depending on use case) - To view, create, search tickets and add articles.
   • user.reader - To view and search users.
   • (Optional) admin.user might be needed for broader user searches or modifications if you add those tools later. Review Zammad's permission documentation for specifics.
7. Click "Create" or "Save".
8. Immediately copy the generated token. Zammad will only show you the token once. Store it securely.

Installation & Setup

1. Clone the repository:

   git clone https://github.com/arush15june/zammad-mcp-go.git
   cd zammad-mcp-go

2. Build the binary:

   go build -o zammad-mcp-go main.go

   This will create an executable file named zammad-mcp-go (or zammad-mcp-go.exe on Windows) in the current directory.
