Install Clocktower in Claude Code, Cursor or VS Code

Runs npx -y croncall on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Clocktower repository's README, as published. We do not edit it. Read it on GitHub

sathergate-toolkit

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

Packages

Or install them all:

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 init) for zero-config setup
  • No external services required — pure TypeScript with zero npm dependencies (optional peer deps for adapters)

Development

npm install
npm run build
npm run test
npm run typecheck
