Koragraph MCP for Claude Code
Four commands, about five minutes, and Claude Code stops reading your repository file by file and starts querying a resolved graph of it. It is free, it runs on your own machine, and no source code is sent anywhere.

Requires

Install
01
Install the server
npm install -g koragraphmcpInstalls the koragraphmcp package globally, which gives you the koragraph command. Needs Node.js 22 or newer.
02
Ingest a repository
koragraph ingest /path/to/repoParses the repository, resolves the relationships between declarations, mines the git history and writes the graph to a local store under your home directory. Run it once per repository you want the agent to know about. Point it at several and their cross service calls resolve between them into one graph.
03
Check the install
koragraph doctorConfirms the server is set up correctly and reports anything that is not. Worth running before you wire it into an agent, so a configuration problem shows up here rather than as an agent that quietly has no tools.
04
Add it to Claude Code
claude mcp add koragraph -s user -- koragraph mcpRegisters the server with Claude Code at user scope, so it is available in every project rather than only the one you happened to be in. Restart Claude Code afterwards and the nine tools appear.
What Claude Code can do afterwards
The server exposes nine tools. Claude Code picks between them on its own, so you keep asking questions in plain English and the tool calls happen underneath.
| Tool | What it answers |
|---|---|
| explore | Symbol or plain English. Ranked declarations plus source, callers, callees. |
| blast_radius | Run before editing. What depends on this, and what has no test coverage. |
| search_code | Locate a name in the graph, not raw text. |
| neighbours | Callers and callees of one symbol. |
| changes_with | What has historically changed together with a symbol. |
| file_symbols | Declarations in one file. |
| overview | Orient on the first turn. Store level index across repos. |
| recall | A failed attempt and its fix, a hazard, a revert. |
| remember | Save a durable, code anchored fact. The only writer. |
Languages it parses
Twelve, through tree-sitter, which is what lets the same extraction behave the same way across all of them: C, C++, C#, Go, Java, JavaScript, PHP, Python, Ruby, Rust, Swift, TypeScript and TSX.
Why bother
Claude Code is already good at reading code. The thing it cannot do on its own is know what it has not read. Without a graph underneath it, answering a question about one function means opening files until the context window fills, and the parts of the answer that live in a repository you did not open never arrive at all.
With the graph, the same question returns a resolved subgraph: the function, its callers, its callees, the tests that cover it, and the calls that cross out of the repository into another service. We publish the measurements behind that claim on the benchmarks page, including the ones where the other system wins.

Get it from GitHub.
One live graph of every repository you point it at, served over the Model Context Protocol, so the agent you already use reads your systems instead of rediscovering them.
