I will build custom mcp server for claude cursor windsurf ai agent API llm integration


About this gig
Your AI Assistant Is Powerful. But It Can't See Your Tools.
Claude, Cursor, and Windsurf are brilliant but without MCP, they can't access your databases, CRMs, or internal APIs. I build the bridge.
Hi, I'm Samuel. I build custom Model Context Protocol (MCP) servers that connect your AI assistant to any tool, database, or API securely, in real time, with no manual copy-pasting.
What I Build:
- Custom MCP server Python or TypeScript
- Compatible with Claude, Cursor, Windsurf, and any MCP client
- Connect to REST APIs, databases (SQL/NoSQL), SaaS tools
- CRM integration (HubSpot, Airtable, Notion, Salesforce)
- Authentication OAuth, API keys, role-based access
- Deployment to your server or cloud (Railway, Fly.io, VPS)
- GDPR/HIPAA-ready architecture available
- Tool chaining for multi-step AI workflows
- Full documentation and onboarding
- n8n + MCP combined architecture
Why Samuel:
- One of the few Fiverr sellers genuinely building production-grade MCP
- Your AI goes from assistant to autonomous operator
- Secure, scalable, no vendor lock-in
- Full handover with code + docs

FAQ
What is an MCP server and why do I need one?
Model Context Protocol is the standard that lets AI assistants like Claude connect to your actual tools — databases, CRMs, APIs — instead of only using what you type in. It's the difference between an AI that talks and an AI that acts.
Which AI tools can your MCP server connect to?
Claude, Cursor, Windsurf, and any LLM that supports the MCP standard, including open-source models like Llama.
What tools or data sources can you integrate?
Any REST API, SQL or NoSQL database, SaaS platform (Notion, HubSpot, Airtable, Salesforce, Slack, GitHub), or internal tool with an accessible endpoint.
Where is the MCP server deployed?
I deploy to Railway, Fly.io, your own VPS, or any cloud provider you prefer. Local deployment for Cursor/Claude Desktop is also supported.
Is it secure?
Yes. I implement OAuth, API key scoping, and role-based access control. GDPR and HIPAA-ready architectures are available on request.
Do I need to be technical to use it?
No. Once it's deployed and connected, your AI assistant uses it automatically. I'll walk you through it on delivery.
Can you combine MCP with n8n?
Yes. MCP + n8n is a powerful combination — MCP gives your AI tool access, n8n handles the automation orchestration.
What language is the MCP server built in?
Python or TypeScript, depending on your preference and stack. Both are fully MCP-spec compliant.
Can the MCP server handle multiple tools?
Yes. Standard and Premium packages support multiple tool integrations in a single MCP server instance.
