kivv

Automated arXiv research paper discovery and AI-powered summarization system with MCP (Model Context Protocol) integration for Claude Desktop. Built as a vibe-coding project, we keep the tooling lightweight and the feedback loop fast so you can stay in flow while shipping research insights.

Features

• Daily Automation: Automatically searches arXiv for papers matching your topics

• AI Summaries: Claude-powered intelligent paper summarization with cost optimization

• Multi-User: Support for multiple users with independent topic configurations

• MCP Integration: Direct integration with Claude Desktop via Model Context Protocol

• RSS Feeds: Per-user RSS/Atom feeds for any feed reader

• Web Dashboard: Optional SvelteKit dashboard (coming soon)

• Cost-Effective: Runs mostly on Cloudflare free tier (~$3/month for 2 users)

Architecture

• MCP Server: TypeScript Worker handling MCP protocol and tool execution

• Daily Automation: Cron-triggered Worker for paper collection and summarization

• Storage: Cloudflare D1 (SQLite), R2 (PDFs), KV (cache)

• AI: Claude 3.5 Sonnet with Haiku triage for cost optimization

Quick Start

Prerequisites

• Cloudflare account with Workers, D1, KV, and R2 enabled

• Anthropic Claude API key (console.anthropic.com)

• Bun 1.1+ (package manager - install from bun.sh)

• Wrangler CLI (installed automatically via bun)

Installation

# Clone the repository
git clone https://github.com/jeffaf/kivv.git
cd kivv

# Install dependencies with bun (our vibe-coding default)
bun install

# Set up environment variables
cp .env.example .env
# Edit .env with your API keys and Cloudflare credentials

Deployment

For complete deployment instructions, see DEPLOYMENT.md.

Quick deployment:

# Set secrets for automation worker
cd automation
wrangler secret put CLAUDE_API_KEY
wrangler secret put CRON_SECRET

# Deploy automation worker
wrangler deploy

# Deploy MCP server
cd ../mcp-server
wrangler deploy

# Configure Claude Desktop (see DEPLOYMENT.md for details)
# Add MCP server URL and API key to Claude Desktop config

Verification

# Test automation worker
curl https://kivv-automation.<username>.workers.dev/health

# Test MCP server
curl https://kivv-mcp.<username>.workers.dev/health

# Check database
wrangler d1 execute kivv-db --command "SELECT COUNT(*) FROM users"

# Or use the automated health check script
./scripts/health-check.sh

See TROUBLESHOOTING.md if you encounter any issues.

Automated Deployment Script

For one-command deployment:

# Run the automated deployment script
./scripts/deploy.sh

# This will:
# - Verify prerequisites
# - Check infrastructure
# - Configure secrets
# - Deploy both workers
# - Provide Claude Desktop config

• Implementation Plan - Chunked development guide

• API Documentation - API endpoints and usage

• PRD (Full Spec) - Complete technical specification

CI & Automation

• Tests & Type Checks: GitHub Actions run bun run type-check and bun test on pushes and pull requests to keep the vibe coding fast without breaking the build.

• Deployments: Cloudflare Workers deploy pipelines trigger when mcp-server/ or automation/ change, using wrangler with your configured Cloudflare credentials.

Development

# Run type checking
bun run type-check

# Run all tests
bun test

# Run security tests specifically
bun run test:security

# Run tests in watch mode
bun run test:watch

# Run MCP server locally
bun run dev:mcp

# Run automation worker locally
bun run dev:automation

# Build all workspaces
bun run build

Testing

The project includes comprehensive test coverage:

• Security Tests (100% coverage required):

  • Authentication (API key validation)

  • Authorization (user data isolation)

  • SQL injection prevention

  • XSS prevention in RSS feeds

  • Rate limiting enforcement

• Integration Tests: End-to-end MCP tool workflows

• Unit Tests: Isolated utility function testing

# Run with coverage report
bun run test:coverage
