DollhouseMCP 2.0

The product is an open-source platform that turns prompts into modular, reusable building blocks — personas, skills, templates, agents, memories, and ensembles — to replace one-off prompts with versioned, combinable AI customization. It is for developers and individual users as well as business teams that customize AI assistants and agents. It is delivered as a local-first MCP server with a GitHub-synced portfolio, public collection marketplace, and server-side Gatekeeper enforcement under AGPL-3.0 with commercial licensing available.
