Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package cg-code-graph

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

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.

Frequently asked questions

What is code-graph?

Local dependency graph: callers, entry points and file:line evidence for what a change affects.

How do I install code-graph?

It runs on your machine. In Claude Code: claude mcp add code-graph -- uvx cg-code-graph==0.23.13 --db --tools. For other clients, paste the JSON configuration from this page into their MCP settings.

Does code-graph need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is code-graph open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains code-graph?

It is published by cyberchronos00. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
