Cas d'usage

Usages concrets : Graphify

Onboard to a 5-year-old legacy codebase in hours, not weeks

👤 New hires, contractors inheriting code ⏱ ~60 min intermediate

Quand l'utiliser : You've joined a project with 10k+ files, dozens of internal services, and tribal knowledge spread across PRs and Confluence.

Prérequis

uv installed — curl -LsSf https://astral.sh/uv/install.sh | sh
Graphify installed globally — uv tool install graphifyy && graphify install

Déroulement

Index the repo

/graphify index /workspace/monolith --include '**/*.{ts,py,md}'✓ Copié

→ Graph builds; report tells you cluster count and dominant concepts
Ask the graph

/graphify query 'how does payment processing connect to audit logging?'✓ Copié

→ Path through concepts with file references — not just a grep
Open the visual

/graphify explain 'user-account cluster' and open the HTML viewer✓ Copié

→ Interactive graph opens; cluster is highlighted with its bridges

Résultat : You know the conceptual shape of the codebase — where the hot paths live, which clusters are isolated, what depends on what.

Pièges

Graph becomes stale as the repo changes — graphify --watch to auto-update; or re-index before a big review session
Noise from vendored deps — Configure --exclude 'node_modules/,vendor/' on initial indexing

Combiner avec : filesystem · context7

Build a research graph over 200 papers and ask cross-paper questions

👤 Researchers, policy analysts, lit-review writers ⏱ ~90 min intermediate

Quand l'utiliser : You have a folder of 200 PDFs and need to find cross-paper threads no single paper exposes.

Déroulement

Index the corpus

/graphify index /research/climate-pdfs✓ Copié

→ Concept clusters emerge (e.g. 'carbon pricing', 'adaptation finance')
Bridge-finding query

/graphify path 'adaptation finance' → 'sovereign debt'✓ Copié

→ Ordered chain of concepts + papers that connect the two
Generate a literature review

Summarize the 'adaptation finance → sovereign debt' bridge as a 400-word section with paper citations.✓ Copié

→ Draft paragraph with correct citations from the graph

Résultat : Insights that come from the structure of the corpus, not just keyword grep.

Pièges

Scanned PDFs don't OCR — Run OCR (ocrmypdf) before indexing; Graphify won't magic-text images

Combiner avec : filesystem

Merge graphs from multiple repos into one searchable view

👤 Platform teams owning microservice fleets ⏱ ~120 min advanced

Quand l'utiliser : You run 15 services. You want one graph that spans them so an agent can follow a request end-to-end.

Déroulement

Index each service

For each repo under /services/, run graphify index with --out graph-<name>.json✓ Copié

→ 15 graph.json files on disk
Merge

graphify merge-graphs graph-*.json --out fleet.json✓ Copié

→ One unified graph with cross-repo edges
Ask end-to-end

/graphify query 'trace a POST /checkout through the fleet'✓ Copié

→ Path through multiple services, each node annotated with its repo

Résultat : Cross-service traceability without a service mesh or OTEL rollout.

Pièges

Same concept named differently across repos — Graphify's similarity merge handles most; for the rest, define aliases in the config

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

graphify-skill + filesystem

Graphify points at files; filesystem lets the agent actually read/edit them

/graphify query 'retry logic' → list files, then filesystem read_text_file each one to draft a refactor.✓ Copié

graphify-skill + github

Turn graph queries into PR plans

Use the graph to find everywhere we do ad-hoc retries; open a GitHub issue listing each file with a proposed consolidation.✓ Copié

graphify-skill + sequential-thinking

Multi-step reasoning that uses the graph as an oracle

Plan the refactor step-by-step; at each step, consult /graphify query for impact.✓ Copié

Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler	Coût
/graphify index	path, include, exclude, --watch	First — build the graph	Claude calls for concept extraction (use prompt caching)
/graphify query	natural-language question	The primary query interface	free (local) + small model call
/graphify path	concept A → concept B	When you want to see how two ideas connect	free
/graphify explain	node/cluster id	Deep-dive on a single cluster	free + small model call
graphify merge-graphs	graph-*.json	Cross-repo / cross-folder views	free

Coût et limites

Coût d'exécution

Quota d'API: Local indexing is free; concept extraction uses Claude API (your key)
Tokens par appel: Indexing a 10k-file repo ≈ tens of dollars with caching; queries are cheap
Monétaire: Free software; pay for the extraction calls only
Astuce: Cache aggressively — Graphify already does prompt caching for extraction; index once, query 1000x

Sécurité

Permissions, secrets, portée

Stockage des identifiants : Uses your Claude API key for extraction; graph.json stored locally

Sortie de données : Concept extraction calls go to Anthropic (your account). No telemetry from Graphify itself.

Ne jamais accorder : Sharing graph.json publicly when indexed from a private repo — it embeds code snippets and filenames

graph.json can contain sensitive snippets. .gitignore it unless you want the graph shared with the repo.
--watch spawns file-system watchers; on huge repos, set include/exclude to avoid pegging a CPU.

Dépannage

Erreurs courantes et correctifs

graphify: command not found after install

uv tool install graphifyy puts the binary in ~/.local/bin; ensure that's on PATH, or run with uv tool run graphify.

Vérifier : uv tool list | grep graphify

Indexing takes forever on a large repo

Scope with --include '**/*.{py,ts,md}' and --exclude 'node_modules/,dist/'. Concept extraction, not parsing, is the bottleneck.

Vérifier : Watch the progress log; parsing should be seconds, extraction takes the time

Queries return irrelevant clusters

Graph quality depends on the index — add README/docs files to the input set so Claude has project context for naming clusters

Vérifier : Rebuild including /docs/**/*.md; queries should sharpen

Merge-graphs produces duplicate nodes

Lower --similarity-threshold (default ~0.8) to 0.7 to merge near-duplicates more aggressively; tune per-repo

Alternatives

Graphify vs autres

Alternative	Quand l'utiliser	Compromis
Serena	You want LSP-precise symbol navigation and refactor tools, not conceptual clusters	No multi-modal input; no clustering
Memory MCP	You want Claude to remember session facts, not index a corpus	No graph; no query-by-concept
Raw embedding + vector DB	You need custom retrieval logic and don't care about community detection	You build the whole pipeline — graphify is opinionated and faster to ship
