The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Koragraph listing page.
Completely free. Runs entirely on your machine.
A local knowledge graph of every repo you point it at, plus a memory layer that knows when the code it remembers has changed.
koragraph doctor checks the whole chain and prints the exact line for any editor.
This is the step that lights up the memory layer, so don't skip it. In your coding agent (Claude Code, Cursor, Windsurf, whatever you use), tell it:
"Read
KORAINIT.mdand follow it."
It imports your existing CLAUDE.md / AGENTS.md into koragraph's memory, anchored to the code
each rule is about, flags any rule that points at code that's already gone, and finishes wiring
koragraph into the session. Run it once per project.
Prefer zero setup? Hand the whole thing to your agent instead. Paste this from the repo you want indexed, and it installs, indexes, wires itself in, and runs KORAINIT for you:
Koragraph turns every repo you point it at into one live graph: a resolved structure, with an edge only where there really is one.
koragraph serve: code (cool nodes) and its memory (gold diamonds), one local page.
Everything your agent learns is saved locally, anchored to the exact declaration, not a line
number. Rename the code and the fact follows; delete it and the fact retires. No CLAUDE.md to
maintain, and it survives every upgrade.
Every graph is graded by an independent compiler front-end (CPython ast, go/parser, Roslyn,
syn, tsc, Ripper, php-ast, ctags, swiftc), never the tool under test. koragraph wins 34 of
39 language×plane cells, and leads precision on all 39.

Reproduces from test/benchmark: pinned corpus, pinned competitor versions,

Nine MCP tools. Every one returns file:line, never pasted source. Exactly one writes.
| Tool | What it's for |
|---|---|
blast_radius | Run before editing. Everything that depends on this, across repos, and what has no test coverage. |
explore | A symbol or plain English gives you ranked declarations, source, callers, callees. |
search_code | Find a name in the graph, not raw text. |
neighbours | Callers and callees of one symbol. |
changes_with | What has historically shipped together with a symbol. |
file_symbols | Declarations in one file. |
overview | Orient on turn one, across every repo. |
recall | A past failure and its fix, a hazard, an open loop. |
remember | Save a durable, code-anchored fact. The only writer. |
Plus a CLI: ingest, serve, status, doctor, diff, trace, hooks, practice, report.
