Serve Version-Correct Context to AI with vg serve

Run vg serve to start Vibgrate AI Context, a local offline MCP server. Build the code map first, then serve your code map, drift, and lockfile-correct library docs to any AI assistant.

Difficulty
Intermediate
Duration
20 minutes
Steps
5

AI assistants give wrong answers when they reason about the wrong version of a library or guess at your code structure. Vibgrate AI Context fixes that: vg serve starts a local, offline MCP server that exposes your code map, your drift, and version-correct library docs pinned to your lockfile — with no account and nothing uploaded. This tutorial gets the server running.

Prerequisites

  • The Vibgrate CLI installed (npm i -g @vibgrate/cli)
  • A project with a lockfile

Steps

1. Install the CLI

npm i -g @vibgrate/cli

2. Build the code map

Vibgrate AI Context serves from a code map artifact. Build it first.

vg build

This maps your source into a graph that powers downstream queries like vg show, vg ask, and vg impact.

3. Start vg serve

vg serve

This launches Vibgrate AI Context — the local, offline MCP server. It serves your code map, your drift, and version-correct library docs to any MCP-capable AI assistant.

4. Understand what is served

Vibgrate AI Context is not docs-only. It serves three things together: your code map (structure, callers, callees), your drift (so the assistant knows what is out of date), and library docs pinned to your lockfile versions. Everything stays local and offline after first use.

5. Verify the server is running

With vg serve running, your AI assistant can query the local MCP endpoint. Leave the process running while you work; stop it with Ctrl+C when done.

Verification

The terminal shows the server has started. Once connected (see the next tutorial), your assistant can answer questions grounded in your actual code map and lockfile versions rather than guessing.

Next Steps

  • Wire it into your editor: "Connect Vibgrate AI Context to Your AI Editor".
  • Precompute the semantic index so the first query is instant with vg embed.

Prerequisites

  • Vibgrate CLI installed
  • A project with a lockfile
  • An AI assistant that supports MCP

Steps

  • 1
    Install the CLI
  • 2
    Build the code map
  • 3
    Start vg serve
  • 4
    Understand what is served
  • 5
    Verify the server is running

│ Top Priority Actions │

1. Upgrade EOL runtime in node-turborepo
End-of-life runtimes no longer receive security patches and block ecosystem upgrades.
./.
>=18.0.0 → 24.0.0 (6 majors behind)
Impact: −10 drift points (runtime & EOL)
 
2. Fix security posture: no lockfile found
Without a lockfile, installs are non-deterministic. Run the install command to generate one and commit it.
./
Missing: package-lock.json, pnpm-lock.yaml, or yarn.lock
 
3. Upgrade Vite 5.4.21 → 8.2.2 in @repo/admin (+2 more)
3 major versions behind. Major framework drift increases breaking change risk and blocks access to security fixes and performance improvements.
./apps/admin
Vite: 5.4.21 → 8.2.2 (3 majors behind)
./apps/api
Vitest: 1.6.1 → 4.1.11 (3 majors behind)
./packages/utils
Vitest: 1.6.1 → 4.1.11 (3 majors behind)
Impact: −5–15 drift points
 
4. Reduce dependency rot in @repo/types (100% severely outdated)
1 of 1 dependencies are 2+ majors behind. Run `npm outdated` and prioritise packages with known CVEs or breaking API changes.
./packages/types
typescript: 5.9.3 → 7.0.2 (2 majors behind)
Impact: −5–10 drift points
 
5. Reduce dependency rot in @repo/database (75% severely outdated)
3 of 4 dependencies are 2+ majors behind. Run `npm outdated` and prioritise packages with known CVEs or breaking API changes.
./packages/database
@prisma/client: 5.22.0 → 7.10.0 (2 majors behind)
prisma: 5.22.0 → 7.10.0 (2 majors behind)
typescript: 5.9.3 → 7.0.2 (2 majors behind)
Impact: −5–10 drift points
