What it does MultiAgentPPT is a Python/Next.js system that generates presentations from a single topic prompt. It chains several specialized agents—outline generation, topic splitting, parallel research with RAG retrieval, summary, and a looped write-and-check cycle—to produce slide content streamed live to a web frontend. The backend also supports exporting to .pptx via python-pptx.

The interesting bit The architecture is deliberately over-engineered in a useful way: instead of one bloated prompt, a PPTChecker agent verifies each slide and retries up to three times, while research agents run in parallel against MCP-connected knowledge sources. The author also replaced title-based deduplication with page_number as a stable ID, which is the kind of boring detail that prevents chaos when content updates mid-stream.

Key highlights

• Uses Google’s ADK and A2A protocol for agent-to-agent communication, plus MCP for tool/retrieval integration
• Research agents run in parallel; results merge into a single summary before slide generation
• Loop-based generation avoids LLM token limits by creating one slide per iteration rather than dumping everything at once
• Frontend shows real-time agent status and streams content as it is produced
• Includes simplified fallback services (simpleOutline, simplePPT) that skip retrieval and concurrency
• Docker Compose setup provided for both frontend and backend

Caveats

• The author explicitly states this version is no longer maintained; a template-based successor (TrainPPTAgent) is recommended instead
• Built-in demo data is limited to an “electric vehicle development overview” sample; real deployments require configuring your own MCP tools, prompts, and RAG data
• Python <3.11 may trigger bugs; the author recommends 3.12
• Editable/downloadable .pptx frontend integration is still listed as unfinished

Verdict Worth a look if you’re studying multi-agent orchestration patterns or building a similar pipeline and want a reference implementation with visible plumbing. Skip it if you need a polished, maintained product—the author already has.
