This is the MCP layer for vaultbox, part of the sathergate-toolkit monorepo. It exposes AES-256-GCM encrypted secrets management for Next.js apps without requiring external vault services. You get tools to encrypt, decrypt, and rotate secrets stored directly in your codebase or environment. The package itself has zero npm dependencies and works entirely in TypeScript. Reach for this when you need stronger than base64 encoding for API keys and tokens but don't want to spin up HashiCorp Vault or AWS Secrets Manager. The MCP server connects via stdio and follows the same agent-native pattern as the other seven packages in the toolkit.
Agent-native infrastructure toolkit for Next.js. 8 packages, zero dependencies, MCP in every one.
| Package | Description | Install |
|---|---|---|
| gatehouse | Drop-in RBAC with role hierarchy | npm i gatehouse |
| shutterbox | Image processing pipeline | npm i shutterbox |
| flagpost | Feature flags with percentage rollouts | npm i flagpost |
| ratelimit-next | Rate limiting (sliding window, token bucket) | npm i ratelimit-next |
| notifykit | Unified notifications (email, SMS, push) | npm i @sathergate/notifykit |
| croncall | Serverless-native cron jobs | npm i croncall |
| vaultbox | AES-256-GCM encrypted secrets | npm i vaultbox |
| searchcraft | Full-text search with BM25 scoring | npm i searchcraft |
Or install them all:
npm i @sathergate/toolkit
import { createFloodgate } from "ratelimit-next";
import { createSifter } from "searchcraft";
import { createFlagpost } from "flagpost";
// Rate limiting
const limiter = createFloodgate({
rules: { api: { limit: 60, window: "1m" } },
});
// Full-text search
const search = createSifter({
schema: { title: { weight: 2 }, body: true },
documents: articles,
});
// Feature flags
const flags = createFlagpost({
flags: {
newSearch: { defaultValue: false, rules: [{ value: true, percentage: 25 }] },
},
});
See the kitchen-sink example for a complete Next.js app using 5 packages together.
Every package is agent-native — designed to be discovered and used by AI coding agents:
