### Description (declared)

# graph-rag

**A local-first Graph RAG knowledge base for coding agents, served over MCP.**

graph-rag ingests the heterogeneous stuff a coding agent needs to reason about —
service docs (PDF), internal Markdown, your source code, and YAML policy files
(Checkov) — into a single **Neo4j knowledge graph**, and exposes it to the agent
over an **MCP server**: hybrid (vector + full-text) search, table-of-contents
navigation, exact policy lookup, code-centrality ranking, graph traversal, and
the agent's own **persistent working memory**.

It runs entirely on your machine. The default embedding model is local, so
ingestion needs no API key and works offline.

## Why

Plain vector RAG loses structure: it can't tell you *which section* a chunk came
from, *what calls* a function, or *which policy applies to* `aws_db_instance`.
graph-rag keeps those relationships as graph edges, so an agent can both search
semantically **and** traverse — "find the retry section, then show me its parent
chapter", "rank this codebase's most-depended-upon functions", "give me the
Checkov rules for this resource type". It also gives the agent a place to
`remember` decisions and `recall` them in a later session.

## Demo

<!-- TODO: add an asciinema / GIF of an agent calling search_code + recall -->

## Install

The PyPI package is [`grag-mcp`](https://pypi.org/project/grag-mcp/) (the name
`graph-rag` was taken); it installs a `grag-mcp` command. No clone needed — run
it straight with [`uv`](https://docs.astral.sh/uv/):

```bash
uvx grag-mcp --help                       # one-off…
