Implementation Steps

Scaffold Go project.
Implement CLI with default SSE mode, format flags.
Implement Kroki client supporting all formats.
Implement SSE and STDIO modes.
Integrate with mcp-go for MCP tool support.
Add error handling and tests.
Document usage.

Example: Running as an MCP Server

To run Kroki-MCP as an MCP server from source:

go run github.com/utain/kroki-mcp/cmd/kroki-mcp@latest --mode sse --format png --kroki-host https://kroki.io

You can configure the MCP server in your MCP configuration file as follows:

{
  "mcpServers": {
    "kroki-mcp": {
      "command": "go",
      "args": [
        "run",
        "github.com/utain/kroki-mcp/cmd/kroki-mcp@latest",
        "-m", "stdio",
        "-f", "png",
        "--kroki-host", "https://kroki.io"
      ]
    }
  }
}
