A test case the skill fixed. Same model, same prompt, with and without the skill.

Prompt

We are deploying a remote, multi-tenant MCP server behind a cloud load balancer for production enterprise client connections. Just draft the recommendation. Which transport protocol fits this production requirement?

MCP Server Builder

Tier: POWERFUL Category: Engineering / AI Integration Maintainer: Claude Skills Team

Overview

Design and ship production-ready MCP (Model Context Protocol) servers from API contracts. Covers tool definition best practices, resource providers, prompt templates, OpenAPI-to-MCP conversion, TypeScript and Python server implementations, transport selection (stdio, SSE, StreamableHTTP), authentication patterns, testing strategies, and deployment configurations. Treats schema quality and tool discoverability as first-class concerns.

Keywords

MCP, Model Context Protocol, MCP server, tool definition, resource provider, prompt template, stdio transport, SSE transport, OpenAPI to MCP, AI tool server, Claude tools

Core Capabilities

Tool design & schema quality — verb-noun naming, description engineering, typed input schemas, LLM-friendly output formatting
Server implementation — TypeScript (@modelcontextprotocol/sdk) and Python (mcp[cli]) servers; tool/resource/prompt registration; structured error handling; logging, auth, and rate-limit middleware
Transport & deployment — stdio (local/CLI), SSE (web), StreamableHTTP (production), Docker containerization, health checks, graceful shutdown
Testing & validation — schema validation, MCP Inspector integration tests, contract/snapshot tests, load testing for remote servers

When to Use

Exposing an internal REST API to Claude, Cursor, or other MCP clients
Replacing brittle browser automation with typed tool interfaces
Building a shared MCP server for multiple teams and AI assistants
Converting an OpenAPI spec into MCP tools automatically
Creating domain-specific tool servers (database, monitoring, deployment)

Clarify First

Before building the server, confirm these inputs. If any is unknown or vague, ASK — do not assume:

Source contract — the OpenAPI spec or API to expose, or whether building tools from scratch (the input the tool definitions and conversion derive from)
Language — TypeScript (@modelcontextprotocol/sdk) or Python (mcp[cli]) (sets the server implementation generated)
Transport — stdio (local/CLI), SSE (web), or StreamableHTTP (production) (drives transport, auth, and deployment patterns)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
