Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

PYPI package cg-code-graph
Claude Code 
claude mcp add code-graph -- uvx cg-code-graph==0.23.13 --db --tools

code-graph

See everything a change affects before you make it: a local, deterministic dependency graph of routes, calls, tables and config, with file:line evidence for every hop.

For you and your AI agent (CLI + MCP). No LLM in the graph.

Quick start

pipx install cg-code-graph          # or: uv tool install cg-code-graph
cg index . --db out/graph.db        # prints starter queries for your repo
cg install --host cursor    # or claude, codex, vscode, …: registers the MCP server and a "use cg first" agent rule
cg reaches table:orders --db out/graph.db   # any table, connection or config key

Try it on a bundled sample, link a frontend to a backend, or connect an agent over MCP: Quick start guide. Other install options (install.sh, Windows, exact-mode toolchains): Install.

cg reaches table:store_books on the bundled Django sample:

dependents: 18 nodes  (code: 6, entry points: 9, other: 3)
== RUNTIME (reached from http_route / ... / queue_job / listener): 5 functions/methods
    catalog.api.create_book  depth=1 conf=resolved  http_route(1)
        path: function:catalog.api.create_book
          -WRITES_TABLE[resolved @ catalog/api.py:27]-> table:store_books
    catalog.signals.review_saved  depth=3 conf=resolved  listener(1)
        path: function:catalog.signals.review_saved
          -DISPATCHES[exact @ catalog/signals.py:12]-> job:catalog.tasks.recompute_rating
          -HANDLED_BY[exact @ catalog/tasks.py:13]-> function:catalog.tasks.recompute_rating
          -READS_TABLE[resolved @ catalog/tasks.py:14]-> table:store_books

What you get

  • reaches, impact, path: every caller, route, job and page that reaches a table, config key or method.
  • cg affected --base main: the tests and entry points a change reaches (--quiet feeds your test runner).
  • Across repos: cg link matches client HTTP calls (frontends and Laravel / Guzzle backends) to server routes, and checks request keys (Laravel FormRequest, Elysia schemas, Nuxt / TypeScript bodies).
  • Route guards: cg routes --writes --unguarded lists routes that write with no auth guard. Laravel checks inside the action count as inline guards unless --strict.
  • Security views: cg surface lists the inbound / outbound attack surface and findings (hardcoded credentials, plaintext protocols, unverified webhooks, unguarded handlers, listeners on all interfaces, disabled TLS / SSH verification, plaintext gRPC, exposed IPC, outbound URLs built from request input) as text, JSON or SARIF, with --fail-on for CI.
  • MCP server (cg-mcp) so agents query the graph instead of grepping. One server can serve many graphs (graphs plus an optional graph argument); a single --db stays one graph. See MCP.
  • Visual view (cg serve) and plan checks (cg plan check) for planned changes.

Comment installer code-graph ?

Il s'exécute sur votre machine. Dans Claude Code : claude mcp add code-graph -- uvx cg-code-graph==0.23.13 --db --tools. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.

Faut-il une clé API pour code-graph ?

Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.

Oui. Son code est sur GitHub sous licence MIT.

Qui maintient code-graph ?

Il est publié par cyberchronos00. AI.tn le référence sans le maintenir ni le recommander.

Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
