Agent-Native Slides

com.agent-native.slides

Open-source AI presentation builder from Builder.io: every app action — generating a deck from a prompt, editing and reordering slides, applying brand styles, sharing — is exposed as an MCP tool, plus an ask-agent meta-tool that hands complex requests to the app's own agent loop. Streamable HTTP with OAuth 2.1 dynamic client registration; MIT-licensed and self-hostable.
