 ## Features
 
 - **Hybrid search** — semantic (pgvector) fused with BM25 keyword ranking (ParadeDB `pg_search`) in a single SQL round-trip.
-- **Two APIs** — a REST API (`/docs` for OpenAPI) and an MCP server over SSE for Claude Desktop, Cursor, and Zed.
+- **Two APIs** — a REST API (`/docs` for OpenAPI) and an MCP server over streamable HTTP for Claude Desktop, Cursor, and Zed.
 - **Pluggable embeddings** — Ollama, sentence-transformers, any OpenAI-compatible endpoint, or Google Gemini.
 - **Pluggable storage** — uploaded files live on local disk by default, or on any number of S3-compatible backends (self-hosted MinIO, AWS S3, …).
 - **Document parsing** — PDF (fast PyMuPDF or OCR-capable docling), Markdown, and plain text out of the box; DOCX/PPTX when the docling backend is enabled — with optional NVIDIA GPU acceleration.
