agentic-atlas-mcp-builder（agentic atlas MCP 构建器）

MCP Builder Skill

Bootstraps new Model Context Protocol servers from natural language descriptions.

Instructions

When the user requests an MCP server or tool:

1. Identify the core functionality from the description
2. Determine the appropriate transport (stdio for CLI, SSE for web)
3. Scaffold a TypeScript or Python MCP server using the official SDK
4. Generate tool definitions from API schemas or describe them manually
5. Include a test harness with example invocations
6. Provide configuration for Claude Code, Cursor, and OpenCode

Features

• TypeScript (recommended) and Python scaffolding
• Auto-generates tool definitions from API schemas (OpenAPI, JSON Schema)
• STDIO and SSE transport support
• Built-in error handling and validation
• Test harness with mock LLM calls
• Claude Code / Cursor / OpenCode configuration snippets

Example

User: "Build an MCP server for our internal issue tracker with create, list, and close operations"

→ Generate: TypeScript MCP server with 3 tools, JSON Schema for each, test harness, Claude Code config

Dependencies

Requires: Node.js 18+, TypeScript, @modelcontextprotocol/sdk
