I will build a custom mcp server for your existing API


About this gig
Connect your AI client to a clearly defined business API through a small custom MCP server.
I build in TypeScript/Node.js or Python, agreed before ordering. Each package covers ONE documented API and ONE selected transport: local stdio or remote Streamable HTTP. You receive source code, tool schemas, input validation, controlled API access, basic error handling, tests and a setup guide. HTTP delivery includes a fixed-token access check; stdio uses the local process boundary.
Basic is a read-only connector. Larger packages add more tools and may include explicitly agreed create/update actions in a sandbox. No payments or destructive operations.
This is one connector, not a general-purpose agent or hosted SaaS. OAuth/SSO, a web UI, multiple tenants, API discovery and production hosting are outside this offer. Please send the API documentation and desired tool examples before ordering.

FAQ
Will this work with my AI client?
We confirm the client's supported MCP transport before ordering. One named client and one transport are in scope. An API key alone does not make a client MCP-compatible.
Can the tools change data?
Basic is read-only. Standard and Premium may include the limited create/update actions listed in the agreed scope, with sandbox examples and explicit permission. Payments, deletion, custom OAuth and multi-user access are excluded.
Do you host the server?
No ongoing hosting is included. I deliver source and setup instructions for your environment. You provide the API account, compatible runtime and any usage fees.
