# BenoStreamDB Model Context Protocol (MCP) Server

`benostreamdb-mcp` is a high-performance Rust server implementing the open [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) for **BenoStreamDB**.

It exposes analytical streaming SQL, vector similarity search, reciprocal rank fusion (RRF) hybrid search, GraphRAG topological traversals, multi-modal ingestion (PDF, Excel, images, code, text), long-term agent memory, and live change data capture (CDC) directly to autonomous AI agents and IDEs (including Claude Desktop, Cursor, Antigravity IDE, and custom agentic frameworks) over standard input/output (stdio JSON-RPC).

## Key Capabilities

- **Analytical Streaming SQL**: Powered by Apache DataFusion with native SIMD-accelerated execution.
- **pgvector-Compatible Vector UDFs**: `vector_distance`, `l2_distance`, `cosine_distance`, and `inner_product` over `Vec<f32>` and stringified vector columns.
- **Hybrid Search (BM25 + Dense Vectors)**: Reciprocal Rank Fusion (RRF) combining keyword BM25 retrieval with vector similarity.
- **GraphRAG Search**: Simultaneous vector search and multi-hop CSR graph traversals for connected knowledge graphs.
- **Persistent Long-Term Agent Memory**: `store_memory` and `recall_memory` tools with automated embedding generation, metadata tagging, and similarity scoring.
- **Multi-Modal Document & Asset Ingestion**:
  - **PDF Documents** (`.pdf`): In-memory full-text extraction via `pdf-extract` with line-bounded semantic chunking.
  - **Excel & Spreadsheets** (`.xlsx`, `.xls`, `.xlsb`, `.ods`): Pure-Rust workbook parsing via `calamine` with automatic schema inference, sheet & row tracking, and typed columns.
  - **Multimodal Images** (`.png`, `.jpg`, `.jpeg`, `.webp`, `.gif`, `.svg`): Byte conversion to base64 Data URIs (`data:im…
