You will get Custom MCP Server - Connect Your Tools to AI Assistants
Project details
I build custom MCP (Model Context Protocol) servers that connect your existing tools, databases, and APIs directly to AI assistants like Claude and ChatGPT. Instead of copy-pasting data between apps, your team asks questions in natural language and gets answers from your actual systems.
Common integrations I build: CRM lookups (query customers, deals, contacts), database access (read and write to PostgreSQL, MySQL, Supabase), internal APIs (connect proprietary tools to AI), SaaS platforms (Slack, Notion, Jira, HubSpot, Stripe), and file systems (search and retrieve documents).
Every MCP server I deliver is production-ready TypeScript with error handling, input validation, and clear documentation. You own the code, it runs in your environment, and your data never leaves your infrastructure.
I built and published a working MCP server for a Neon CRM system with full CRUD operations, demonstrating exactly the kind of integration I deliver for clients. You can see it in my portfolio.

About Yigal
Claude & AI Integration Developer | MCP Servers, n8n, Next.js
Eindhoven, Netherlands - 7:18 am local time
What I deliver:
MCP servers - custom integrations that connect your tools, databases, and APIs to AI assistants via Model Context Protocol. Your team queries data and triggers workflows through natural language.
AI chatbots and agents (OpenAI, Claude, GPT-4o, RAG) - customer support, lead qualification, data processing. One demo handles 50+ document sources with sub-second retrieval.
Workflow automation with AI (n8n, Make, Zapier + LLMs) - turn multi-step manual processes into one-click automations.
Web apps and dashboards with built-in AI features (Next.js, Supabase, Tailwind).
Mobile E2E test automation (Maestro) - automated QA suites for Android and iOS apps.
API integrations - connect AI to your existing tools (CRMs, messaging platforms, databases).
My stack: Claude API, OpenAI API, MCP (Model Context Protocol), n8n, Make, Zapier, Next.js, React, Node.js, TypeScript, Supabase (+ pgvector for RAG), Tailwind CSS, Stripe, Twilio, WhatsApp Business API
How I work:
You get working prototypes fast, not slide decks.
Based in the Netherlands (CET), responsive during EU and US-East business hours.
Clear async communication, you'll always know where things stand.
Clean, documented code you can maintain and build on.
I use AI tools like Claude to accelerate development. All code is reviewed, tested, and production-quality.
Available for fixed-price projects and hourly contracts.
Message me about your project and I'll let you know how I can help.
Steps for completing your project
After purchasing the project, send requirements so Yigal can start the project.
Delivery time starts when Yigal receives requirements from you.
Yigal works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery and scoping call
We review your tools, data sources, and workflows. I map out which integrations deliver the most value and define the exact scope, so there are no surprises.
Build and test the MCP server
I build the server in TypeScript with full error handling, connect each tool or API, and test every integration against real data. You get progress updates throughout.
