MCP Server Bash SDK
Skill by ara.so — MCP Skills collection.
Overview
The MCP Server Bash SDK is a lightweight, zero-overhead implementation of the Model Context Protocol (MCP) server in pure Bash. It allows you to create MCP servers without Node.js, Python, or other heavy runtimes—just Bash and jq for JSON processing. The SDK handles JSON-RPC 2.0 protocol communication over stdio while you focus on implementing tool functions.
Key Benefits:
- Zero runtime overhead compared to Node.js/Python
- Simple function-based tool definition
- Automatic tool discovery via naming convention
- External JSON configuration for tools and server metadata
- Perfect for API wrappers and system utilities
