description: Haystack is deepset's open-source Python framework for building context-engineered,
  production-ready LLM applications - modular Pipelines and agent workflows assembled
  from 100+ Components and document stores for RAG, semantic search, and agents. Haystack
  pipelines deploy as REST services via Hayhooks, and the commercial deepset AI Platform
  (deepset Cloud) exposes a hosted REST API at api.cloud.deepset.ai for pipelines,
  search, files, and workspaces.

    optional MCP server) with one command, auto-generating OpenAPI/Swagger docs and
    HTTP run endpoints. The deployed surface is generated per pipeline and self-hosted,
