### Description (declared)

# Knowledge GraphRAG MCP Server

A local-first **Model Context Protocol (MCP)** server that watches a knowledge repository, extracts entities and relations, embeds content with EmbeddingGemma, and serves hybrid (graph + vector) retrieval tools to MCP clients.

- **Local pipeline:** directory watcher → normalization → chunking → entity & relation extraction → sqlite-vec vectorization → graph storage
- **Knowledge graph:** canonical entities, mentions, and typed relations navigated via the bundled `bfsvtab` breadth-first search extension
- **Hybrid retrieval:** semantic vector prefiltering paired with graph expansion and provenance-rich responses

All native dependencies ship with the Python package—no external services or manual compilation required.

## Feature Overview

| Area | Highlights |
| --- | --- |
| Document ingestion | Markdown/HTML/txt normalization, deduplication, preludes for provenance |
| Entity understanding | Mention extraction, canonical linking, relation inference (`uses`, `depends_on`, `defines`, `cites`, …) |
| Storage | SQLite with WAL, `sqlite-vec` for vectors, `bfsvtab` for graph traversal |
| Retrieval tools | Vector + graph search, entity lookup/explain, ingestion/refresh controls, status reporting |
| Local-first | EmbeddingGemma model runs locally (or via optional remote endpoint) |

## Quick Start with `uvx`

The published wheel already includes the native SQLite extensions. You can run the CLI without cloning the repository:

```bash
# Inspect available commands
uvx knowledge-graphrag-mcp --help

# Initialize the database and report status
uvx knowledge-graphrag-mcp status --config config.yaml

# Ingest Markdown files inside a knowledge directory
uvx knowledge-graphrag-mcp ingest ./knowledge/**/*.md --config config.yaml

# Issue a hybrid retrieval query
uvx knowledge-graphrag-mcp hybrid-query "data retention policy" --config config.yaml
```

### Minimal configuration (`config.yaml`)

```yaml
project: "knowledge-graphrag"
sqlite:
  path…
