Compares GitNexus, Graphify, and CodeGraph — tools that precompute a structural knowledge graph of a codebase and expose it to AI coding agents via MCP, replacing repeated grep/file-read exploration with direct impact-radius, call-chain, and dependency queries. Use when a user asks to "give my coding agent a code graph," "reduce how many tool calls/tokens my agent burns exploring the repo," "set up GitNexus/Graphify/CodeGraph," "find an MCP tool for codebase structure," or is choosing between these three tools based on license, language coverage, or query model.

Code Knowledge Graph Tools for AI Agents

Purpose

An AI coding agent without any precomputed structural index explores a codebase the same slow way every time: repeated grep, file reads, and directory listings to reconstruct facts (what calls this function, what would break if I change this type, what's the blast radius of this file) that are stable properties of the code and don't need to be rediscovered on every session. Code-knowledge-graph tools solve this by parsing the codebase once into a structural graph (or graph-like index) — call graphs, type relationships, module dependencies — and exposing queries over that graph to the agent via MCP tools, so a question like "what depends on this function" becomes one precomputed lookup instead of a multi-step grep-and-read exploration the agent has to redo from scratch each time. This is a distinct concern from a RAG pipeline's semantic retrieval over document/code text (rag-pipeline-design) and from operating a general-purpose vector database (vector-database-operations-pinecone-weaviate-milvus): a code knowledge graph indexes structure (calls, references, definitions, dependencies), not just embedding-similar text chunks, though some of these tools combine both. This skill compares three current tools in this space — GitNexus, Graphify, and CodeGraph — on architecture, language coverage, query model, and licensing, and covers choosing between them and wiring the one you pick into an agent via MCP (mcp-server-development covers building an MCP server generally; this skill covers consuming these three specific pre-built ones).

When to use

  • An AI coding agent repeatedly burns tool calls and tokens re-exploring the same codebase structure (grep for callers, read files to trace a type) across sessions, and you want to give it a precomputed structural index instead.
  • Deciding which of GitNexus, Graphify, or CodeGraph fits a given repository's language mix, size, and licensing constraints (open-source vs. commercial product).
  • Setting up impact-radius or blast-zone analysis before a refactor — "what breaks if I change this function's signature" — as a query an agent can run directly rather than inferring from manual exploration.
  • A codebase includes non-code artifacts (design docs, PDFs, recorded walkthrough videos) that should also be queryable alongside code structure, favoring a tool that ingests more than source files.
  • Evaluating whether a commercial product can adopt one of these tools, which requires checking each tool's license (GitNexus's noncommercial license is a real blocker for commercial use without a paid tier; Graphify and CodeGraph are fully permissive).

Prerequisites & environment

  • Node.js and npx availability for GitNexus (npx gitnexus analyze && npx gitnexus setup).
  • The uv Python package/tool manager for Graphify (uv tool install graphifyy).
  • A Rust-toolchain-built binary or published release for CodeGraph (it is itself implemented in Rust for its parsing kernel — no Rust toolchain is required on the consuming machine unless building from source).
  • An MCP-compatible agent host (Claude Code, Cursor, GitHub Copilot, Gemini CLI) configured to connect to the tool's MCP server, per each client's own MCP configuration mechanism.
  • Disk space for the generated index: GitNexus stores its embedded graph+vector database (LadybugDB) under a .gitnexus/ directory in the repo; Graphify's and CodeGraph's index storage location should be confirmed against each tool's current documentation before assuming a fixed path.
  • For Graphify's documentation/PDF/video ingestion: access to the user's own configured AI model (Graphify uses it as part of ingestion) and a local faster-whisper transcription setup for video content — this is a heavier prerequisite than pure source-code parsing and should be scoped in before enabling it on a large corpus of recorded content.
  • Legal/procurement sign-off before adopting GitNexus for any commercial codebase — its license (PolyForm Noncommercial 1.0.0) permits open-source and non-commercial use only; commercial use requires a paid enterprise tier. This is not a fully permissive open-source license and should be flagged to whoever approves tooling for a commercial product, the same way you'd flag a GPL/AGPL dependency in software-composition-analysis-sca.

Step-by-step guidance

  1. Understand what each tool actually indexes and how, before choosing:

    • GitNexus: uses Tree-sitter to extract an AST across 14 languages, then stores the resulting structure in LadybugDB, an embedded graph+vector database, persisted under a .gitnexus/ directory in the repository. It exposes 17 MCP tools for queries like impact-radius, call-chain, and blast-zone analysis — i.e. the query surface is deliberately broad and granular (many narrow tools rather than one general one).
    • Graphify: uses tree-sitter across 36+ languages — a wider language surface than GitNexus — and additionally ingests documentation, PDFs, and video (video transcribed locally via faster-whisper, using the user's own configured AI model as part of ingestion). It clusters the resulting structure using Leiden community detection (a graph-clustering algorithm that groups densely-connected nodes into communities), and exposes a CLI-style query surface: graphify query, graphify path, graphify explain.
    • CodeGraph: implemented with a Rust-powered parsing kernel across 20+ languages, storing the result in a local SQLite database with FTS5 (SQLite's full-text search extension) rather than a dedicated graph database. It exposes a single primary MCP tool, codegraph_explore, and includes a live file-watcher that auto-syncs the index as files change, rather than requiring a manual re-index step.

  2. Install and index the codebase with the chosen tool:

    # GitNexus
npx gitnexus analyze && npx gitnexus setup

# Graphify
uv tool install graphifyy
graphify query "..."      # query commands available after install/index

# CodeGraph — consult the current release for the exact install command;
# its file-watcher then keeps the SQLite/FTS5 index in sync automatically

  3. Wire the tool's MCP server into your agent host. All three are designed to be consumed by an MCP-compatible agent — the exact client config (where you register the server command) is client-specific (Claude Code, Cursor, Gemini CLI, GitHub Copilot each have their own MCP config location); see mcp-server-development for the general client/server wiring pattern these tools' own MCP servers follow.

  4. Match the query granularity to the tool you chose. GitNexus's 17 distinct MCP tools mean an agent (or you, reviewing its tool calls) should expect fairly specific, purpose-named queries (e.g. a dedicated impact-radius tool vs. a dedicated call-chain tool) rather than one general-purpose entry point. CodeGraph inverts this: a single codegraph_explore tool is the primary surface, so most exploratory questions route through it rather than a large discrete toolset — fewer tool names for the agent to choose between, at the cost of a less explicitly named query surface. Graphify sits outside the MCP-tool-count framing entirely for its documented interface, exposing query/path/ explain as CLI commands.

  5. Decide before adoption whether commercial use is in scope, since this changes which tools are even eligible:

    • GitNexus is licensed under PolyForm Noncommercial 1.0.0 for open-source/non-commercial use, with a paid enterprise tier required for commercial use. Treat this the same as you would any non-permissive dependency license found by an SCA/license scanner — flag it explicitly to whoever owns license compliance before adopting it inside a commercial product, rather than assuming "open-source tooling" implies free commercial use.
    • Graphify is dual-licensed Apache-2.0 and MIT — fully permissive, no commercial-use restriction.
    • CodeGraph is MIT-licensed — fully permissive, no commercial-use restriction.

  6. If the corpus includes non-code material (design docs, PDFs, recorded architecture walkthroughs), Graphify is the only one of the three with documented ingestion for that content type (via the user's AI model plus local faster-whisper transcription for video) — GitNexus and CodeGraph are scoped to source-code parsing.

  7. If continuous freshness matters more than query breadth, CodeGraph's live file-watcher auto-sync is a meaningful operational difference: the index updates as files change without a separate manual re-index step, which matters for an agent working against a codebase that's being actively edited in the same session (including by the agent itself).

  8. Where a measured before/after comparison exists, use it, and don't invent numbers for tools where it doesn't. CodeGraph publishes a measured impact across 7 real-world repositories: 89% fewer tool calls, 60% lower cost, and 69% fewer tokens versus agents operating without any such index. No comparable measured figures are given here for GitNexus or Graphify — do not assume or restate CodeGraph's numbers as if they apply to the other two tools; if a similar before/after comparison matters for your decision, run it yourself against your own codebase and agent workflow rather than assuming parity.

Best practices

  • Pick based on language coverage first if your codebase is polyglot: Graphify's 36+ languages is the widest of the three, CodeGraph's 20+ is next, GitNexus's 14 is narrowest — confirm your specific languages are covered before committing, since "covers most languages" claims vary in how current/complete support actually is per language.
  • Treat GitNexus's license as a hard commercial-use gate, not a footnote — confirm with whoever owns license/legal compliance before using it on any codebase tied to a commercial product, and budget for the paid enterprise tier if commercial use is required.
  • Prefer CodeGraph's live file-watcher when the agent is actively modifying the same codebase it's querying in one session — a stale index (requiring manual re-index) can give an agent confidently wrong structural answers mid-refactor.
  • Don't adopt Graphify's documentation/PDF/video ingestion by default if all you need is code structure — it's a genuinely distinct, heavier capability (local transcription, additional AI-model calls at ingestion time) that's worth its cost only when the non-code corpus actually matters to the agent's task.

# Code Knowledge Graph Tools for AI Agents

## Purpose

An AI coding agent without any precomputed structural index explores a
codebase the same slow way every time: repeated `grep`, file reads, and
directory listings to reconstruct facts (what calls this function, what
would break if I change this type, what's the blast radius of this file)
that are stable properties of the code and don't need to be rediscovered on
every session. Code-knowledge-graph tools solve this by parsing the
codebase once into a structural graph (or graph-like index) — call graphs,
type relationships, module dependencies — and exposing queries over that
graph to the agent via MCP tools, so a question like "what depends on this
function" becomes one precomputed lookup instead of a multi-step
grep-and-read exploration the agent has to redo from scratch each time.
This is a distinct concern from a RAG pipeline's semantic retrieval over
document/code *text*
([rag-pipeline-design](../rag-pipeline-design/SKILL.md)) and from operating
a general-purpose vector database
([vector-database-operations-pinecone-weaviate-milvus](../vector-database-operations-pinecone-weaviate-milvus/SKILL.md)):
a code knowledge graph indexes *structure* (calls, references, definitions,
dependencies), not just embedding-similar text chunks, though some of these
tools combine both. This skill compares three current tools in this space —
GitNexus, Graphify, and CodeGraph — on architecture, language coverage,
query model, and licensing, and covers choosing between them and wiring the
one you pick into an agent via MCP
([mcp-server-development](../mcp-server-development/SKILL.md) covers
building an MCP server generally; this skill covers consuming these three
specific pre-built ones).

## When to use

- An AI coding agent repeatedly burns tool calls and tokens re-exploring the
  same codebase structure (grep for callers, read files to trace a type)
  across sessions, and you want to give it a precomputed structural index
  instead.
- Deciding which of GitNexus, Graphify, or CodeGraph fits a given
  repository's language mix, size, and licensing constraints (open-source
  vs. commercial product).
- Setting up impact-radius or blast-zone analysis before a refactor — "what
  breaks if I change this function's signature" — as a query an agent can
  run directly rather than inferring from manual exploration.
- A codebase includes non-code artifacts (design docs, PDFs, recorded
  walkthrough videos) that should also be queryable alongside code
  structure, favoring a tool that ingests more than source files.
- Evaluating whether a commercial product can adopt one of these tools,
  which requires checking each tool's license (GitNexus's noncommercial
  license is a real blocker for commercial use without a paid tier; Graphify
  and CodeGraph are fully permissive).

## Prerequisites & environment

- Node.js and `npx` availability for GitNexus (`npx gitnexus analyze && npx
  gitnexus setup`).
- The `uv` Python package/tool manager for Graphify (`uv tool install
  graphifyy`).
- A Rust-toolchain-built binary or published release for CodeGraph (it is
  itself implemented in Rust for its parsing kernel — no Rust toolchain is
  required on the *consuming* machine unless building from source).
- An MCP-compatible agent host (Claude Code, Cursor, GitHub Copilot, Gemini
  CLI) configured to connect to the tool's MCP server, per each client's own
  MCP configuration mechanism.
- Disk space for the generated index: GitNexus stores its embedded
  graph+vector database (LadybugDB) under a `.gitnexus/` directory in the
  repo; Graphify's and CodeGraph's index storage location should be
  confirmed against each tool's current documentation before assuming a
  fixed path.
- For Graphify's documentation/PDF/video ingestion: access to the user's

  local `faster-whisper` transcription setup for video content — this is a
  heavier prerequisite than pure source-code parsing and should be scoped
  in before enabling it on a large corpus of recorded content.
- Legal/procurement sign-off before adopting GitNexus for any commercial
  codebase — its license (PolyForm Noncommercial 1.0.0) permits open-source
  and non-commercial use only; commercial use requires a paid enterprise
  tier. This is not a fully permissive open-source license and should be
  flagged to whoever approves tooling for a commercial product, the same

  [software-composition-analysis-sca](../../../devsecops/skills/software-composition-analysis-sca/SKILL.md).

## Step-by-step guidance

1. **Understand what each tool actually indexes and how, before choosing:**
   - **GitNexus**: uses Tree-sitter to extract an AST across 14 languages,
     then stores the resulting structure in **LadybugDB**, an embedded
     graph+vector database, persisted under a `.gitnexus/` directory in the
     repository. It exposes **17 MCP tools** for queries like impact-radius,
     call-chain, and blast-zone analysis — i.e. the query surface is
     deliberately broad and granular (many narrow tools rather than one
     general one).
   - **Graphify**: uses tree-sitter across **36+ languages** — a wider
     language surface than GitNexus — and additionally ingests
     documentation, PDFs, and video (video transcribed locally via
     `faster-whisper`, using the user's own configured AI model as part of
     ingestion). It clusters the resulting structure using **Leiden
     community detection** (a graph-clustering algorithm that groups
     densely-connected nodes into communities), and exposes a CLI-style
     query surface: `graphify query`, `graphify path`, `graphify explain`.
   - **CodeGraph**: implemented with a Rust-powered parsing kernel across
     **20+ languages**, storing the result in a local **SQLite database
     with FTS5** (SQLite's full-text search extension) rather than a
     dedicated graph database. It exposes a single primary MCP tool,
     **`codegraph_explore`**, and includes a **live file-watcher** that
     auto-syncs the index as files change, rather than requiring a manual
     re-index step.

2. **Install and index the codebase** with the chosen tool:
   ```bash
   # GitNexus
   npx gitnexus analyze && npx gitnexus setup

   # Graphify
   uv tool install graphifyy
   graphify query "..."      # query commands available after install/index

   # CodeGraph — consult the current release for the exact install command;
   # its file-watcher then keeps the SQLite/FTS5 index in sync automatically
   ```

3. **Wire the tool's MCP server into your agent host.** All three are
   designed to be consumed by an MCP-compatible agent — the exact client
   config (where you register the server command) is client-specific
   (Claude Code, Cursor, Gemini CLI, GitHub Copilot each have their own MCP
   config location); see
   [mcp-server-development](../mcp-server-development/SKILL.md) for the
   general client/server wiring pattern these tools' own MCP servers
   follow.

4. **Match the query granularity to the tool you chose.** GitNexus's 17
   distinct MCP tools mean an agent (or you, reviewing its tool calls)
   should expect fairly specific, purpose-named queries (e.g. a dedicated
   impact-radius tool vs. a dedicated call-chain tool) rather than one
   general-purpose entry point. CodeGraph inverts this: a single
   `codegraph_explore` tool is the primary surface, so most exploratory
   questions route through it rather than a large discrete toolset — fewer
   tool names for the agent to choose between, at the cost of a less
   explicitly named query surface. Graphify sits outside the MCP-tool-count
   framing entirely for its documented interface, exposing `query`/`path`/
   `explain` as CLI commands.

   this changes which tools are even eligible:

     flag it explicitly to whoever owns license compliance before adopting
     it inside a commercial product, rather than assuming "open-source
     tooling" implies free commercial use.
   - Graphify is **dual-licensed Apache-2.0 and MIT** — fully permissive,
     no commercial-use restriction.
   - CodeGraph is **MIT**-licensed — fully permissive, no commercial-use
     restriction.

6. **If the corpus includes non-code material** (design docs, PDFs, recorded
   architecture walkthroughs), Graphify is the only one of the three with
   documented ingestion for that content type (via the user's AI model plus
   local `faster-whisper` transcription for video) — GitNexus and CodeGraph
