I will build a custom mcp server for private apis and databases
Gagan Sahay
About this gig
Connect Claude, ChatGPT, or another AI client securely to your private tools and business data with a custom Model Context Protocol (MCP) server.
I will build an MCP server that exposes approved API actions, database queries, files, or internal services as reliable AI tools.
WHAT YOU RECEIVE
MCP tools and resources for your use case
Private API or database integration
Input validation and structured responses
Authentication, permissions, and secret handling
Error handling and logging
Test client and example prompts
Source code, setup guide, and handover notes
USE CASES
Internal operations assistants
CRM, ERP, and support workflows
Secure database lookup
Developer and DevOps tools
I can build with Python or TypeScript and integrate REST, GraphQL, PostgreSQL, MySQL, Supabase, or other approved systems.
Please message me before ordering if the API is undocumented, the database is production-only, or you need SSO, private-cloud deployment, or strict compliance.
Hosting, paid APIs, and third-party licenses are not included. I use least-privilege access and secure credential handling.
