kslide is a tool for creating and manipulating PowerPoint-style slideshows. It provides both a command-line interface and an MCP (Model Context Protocol) server for AI integration.

• Java 17+
• Kotlin 1.9.25
• Gradle 7.6+

1. Clone the repository:

   git clone https://github.com/karlll/kslide.git
   cd kslide

2. Build the project:

   ./gradlew build -Pversion=0.0.1-SNAPSHOT

3. Run tests:

   ./gradlew test

• Apache POI 5.4.0: PowerPoint file manipulation and formatting
• Flexmark-Java 0.64.8: CommonMark/Markdown parsing and processing
• Kotlin Standard Library: Core Kotlin functionality

• Spring Boot 3.5.0: Application framework and dependency injection
• Spring Shell 3.4.0: Interactive command-line interface
• Spring AI 1.0.0: MCP server integration for AI clients
• Jackson Kotlin Module: JSON serialization/deserialization

• JUnit 5: Testing framework
• MockK 1.13.10: Kotlin-specific mocking library

The MCP server enables AI clients to generate PowerPoint slideshows programmatically.

• Template-based slideshow creation with configurable layouts
• Markdown support for rich text formatting
• Slide content management with placeholder-based content insertion
• File export to PowerPoint (.pptx) format

1. Build the MCP server:

   ./gradlew :mcp:bootJar -Pversion=0.0.1-SNAPSHOT

2. Configure Claude Desktop (example configuration):

   {
     "mcpServers": {
       "kslide-mcp": {
         "command": "java",
         "args": [
           "-Dspring.ai.mcp.server.stdio=true",
           "-Dspring.main.web-application-type=none",
           "-Dlogging.pattern.console=",
           "-jar",
           "/path/to/kslide/mcp/build/libs/kslide-mcp-0.0.1-SNAPSHOT.jar",
           "--templatePath=/path/to/kslide/templates",
           "--outputPath=/path/to/kslide/output"
         ]
       }
     }
   }

   alternatively, use the Docker image as described in the Docker section.

   {
     "mcpServers": {
       "kslide-mcp": {
         "command": "docker",
         "args": [
           "run",
           "--name",
           "kslide-mcp-server",
           "-v",
           "/path/to/kslide/templates:/app/templates",
           "-v",
           "/path/to/kslide/output:/app/output",
           "-i",
           "--rm",
           "kslide-mcp-server"
         ]
       }
     }
   }

Using kslide, create a slideshow about dogs with 5 to 10 slides. Select suitable layout for each slide. When done, save the slideshow as "dogs-slideshow-2".

• Also see resulting PPTX.

listTemplates()

• Lists all available PowerPoint templates

listLayouts(template: String)

• Shows available slide layouts for a specific template

createSlideshow(template: String)

• Creates a new slideshow using the specified template
• Returns a unique slideshow identifier

createSlide(slideshowId: String, layoutIndex: Int, content: Map<Int, String>)

• Creates a slide with plain text content
• Content map: placeholder ID → text content

createSlideWithMarkdown(slideshowId: String, layoutIndex: Int, content: Map<Int, String>)

• Creates a slide with markdown-formatted content
• Supports: **bold**, *italic*, `code`, and - bullet lists
• Content map: placeholder ID → markdown content

saveSlideshow(slideshowId: String, fileName: String)

• Exports the slideshow to a PowerPoint file

// 1. List available templates
listTemplates()
// → "Available templates: - 'Default', A simple template with 17 different slide layouts."

// 2. Check available layouts
listLayouts("Default")
// → Shows layouts with their indices and descriptions

// 3. Create a new slideshow
createSlideshow("Default")
// → "Slideshow created. Identifier: 123e4567-e89b-12d3-a456-426614174000"

// 4. Create slides with markdown content
createSlideWithMarkdown(
    "123e4567-e89b-12d3-a456-426614174000",
    0,
    {
        1: "# Main Title with **bold** text",
        2: "- First bullet point\n- Second point with *italic*\n- Code example: `console.log('hello')`"
    }
)

// 5. Save the slideshow
saveSlideshow("123e4567-e89b-12d3-a456-426614174000", "my-presentation")
// → Saves as "my-presentation.pptx"

The Spring Shell-based CLI provides an interactive interface for slideshow creation and manipulation.

./gradlew :shell:bootRun

The CLI organizes commands into functional groups:

• New Commands: Create slideshows, slides, text boxes, paragraphs, text runs, and bullets
• List Commands: Display slideshows, slides, layouts, and content information
• Set Commands: Configure active elements and properties
• Load Commands: Import templates and existing slideshows
• Write Commands: Export slideshows to files
• Delete Commands: Remove slideshows, slides, and content elements
• Clear Commands: Clear content from text boxes and paragraphs

[To be added]

You can also run the MCP server in a Docker container.

There are two Dockerfiles available:

• Dockerfile.mcp, multi-stage build for MCP Server
• Dockerfile.mcp.local, simple runtime-only Dockerfile for pre-built JAR

To build the Docker image for the MCP server, run:

docker build -t kslide-mcp-server -f Dockerfile.mcp .

To run the MCP server in a Docker container, use:

docker run --name kslide-mcp-server -i --rm \
  -v /path/to/templates:/app/templates \
  -v /path/to/output:/app/output \
  kslide-mcp-server
