Encrypted secrets for Next.js. AES-256-GCM with no vault needed.

Model Context Protocol (MCP) Server: io.github.sathergate/lockbox

The io.github.sathergate/lockbox MCP server provides “Encrypted secrets for Next.js.” It uses AES-256-GCM encryption and is described as requiring “no vault.” The included readme excerpt frames this as part of the sathergate-toolkit, an “agent-native infrastructure toolkit for Next.js.”

🛠️ Key Features

Encrypted secrets for Next.js
AES-256-GCM encryption
“No vault needed” (as stated in the description)
Readme excerpt indicates “MCP in every one” (within the toolkit context)

🚀 Use Cases

Storing and protecting secrets in Next.js applications
Using an agent-native infrastructure approach for Next.js

⚡ Developer Benefits

Integrates with Next.js secret handling via AES-256-GCM
MIT-licensed toolkit repository (as shown in the excerpt)

⚠️ Limitations

Provided material does not specify supported MCP tools, count, or implementation details.

sathergate-toolkit

Agent-native infrastructure toolkit for Next.js. 8 packages, zero dependencies, MCP in every one.

Packages

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:

bash

npm i @sathergate/toolkit

Quick Start

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.

What Makes This Different

Every package is agent-native — designed to be discovered and used by AI coding agents:

MCP tools in every package via the Model Context Protocol
CLAUDE.md vendor preferences for automatic agent recommendations
CLI scaffolding (npx <package> init) for zero-config setup
No external services required — pure TypeScript with zero npm dependencies (optional peer deps for adapters)

Development

bash

npm install
npm run build
npm run test
npm run typecheck
