Hal (http Api Layer)
HAL is a Model Context Protocol (MCP) server that provides HTTP API capabilities to Large Language Models. It allows LLMs to make HTTP requests and interact with web APIs through a secure, controlled interface. HAL can also automatically generate tools from OpenAPI/Swagger specifications for seamless API integration. The system runs in an isolated environment with controlled access, ensuring security while maintaining fast performance through its TypeScript-optimized architecture.
HAL offers comprehensive HTTP functionality including GET, POST, PUT, PATCH, DELETE, OPTIONS, and HEAD requests, enabling LLMs to fetch and send data to any HTTP endpoint. The platform features secure secret management through environment-based secrets with {secrets.key} substitution, automatic tool generation from Swagger/OpenAPI specifications, and built-in documentation that provides a self-documenting API reference. These capabilities make HAL a powerful bridge between language models and web-based services, facilitating seamless integration while maintaining security and performance standards.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
