The io.github.sathergate/darkroom server provides an image processing pipeline for Next.js, enabling responsive optimization with Sharp. It focuses on efficient image handling within a Next.js context and integrates with an MCP-based architecture across packages.

🛠️ Key Features

Image processing pipeline for Next.js
Responsive image optimization using Sharp
MCP (Model Context Protocol) in every package
Lightweight, zero-dependency approach per package

🚀 Use Cases

Optimizing images for responsive, high-performance Next.js sites
Integrating image transformations into server-side rendering workflows
Reusing MCP-enabled infrastructure across multiple packages

⚡ Developer Benefits

Consistent MCP implementation across the toolkit
Clear, package-level RBAC and infrastructure tooling guidance
Open-source licensing and CI workflow references

⚠️ Limitations

Source data excerpt focuses on tooling and pipeline description; detailed implementation may require consulting individual packages within the repository

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)
