Want Claude Desktop or Cursor to connect directly to your private databases, APIs, and business tools?
I am Johan Garcia, a Level 2 Seller with 10+ years of software architecture experience on Fiverr. I build custom, production-grade Model Context Protocol (MCP) servers in TypeScript that transform Claude and Cursor into autonomous powerhouses.

Databases: PostgreSQL, Supabase, MySQL, MongoDB & Redis with secure query tools.
Custom APIs: Proprietary REST, GraphQL or webhook integrations with strict Zod validation.
Business SaaS: Stripe, Slack, GitHub, Jira, HubSpot, or Notion tool-calling.
File Systems: Dynamic resource handlers, log parsers, and custom local developer workflows.
What I Deliver:
Turnkey MCP Server: Clean TypeScript architecture following official Anthropic MCP specs.
Ready Configuration: Plug-and-play claude_desktop_config.json & Cursor IDE integration.
Clear Documentation: Step-by-step setup guide, environment schemas & test cases.

FAQ
What is an MCP server and how does it work with Claude and Cursor?
Model Context Protocol (MCP) is the open standard created by Anthropic that allows AI models like Claude Desktop and Cursor IDE to securely access your local tools, databases, APIs, and file systems. It enables the AI to execute real actions and retrieve live data directly inside your workflow.
What programming language and transport protocol do you use?
I build MCP servers in TypeScript using Node.js and the official @modelcontextprotocol/sdk. I support both stdio transport (ideal for local Claude Desktop and Cursor usage) and SSE (Server-Sent Events) for remote or cloud-hosted deployments.
How do I install and activate the MCP server in Claude or Cursor?
I provide a complete turnkey setup. You will receive a ready-to-use JSON configuration snippet to paste into your claude_desktop_config.json file or Cursor Settings, along with clear documentation and remote onboarding assistance.
How is database and API credential security handled?
Security is top priority. All sensitive API keys, database connection strings, and tokens are loaded strictly via local environment variables (.env). No credentials are ever hardcoded or exposed to the model context.
Can you connect my custom proprietary database or internal company API?
Yes! I can connect any database (Supabase, PostgreSQL, MySQL, MongoDB, Redis) or proprietary REST/GraphQL API. Every tool is built with strict Zod schema validation so the AI calls your endpoints with perfect parameters.
