HAL
Empowers Large Language Models to make HTTP requests and interact with web APIs through a secure, controlled interface.
About
HAL (HTTP API Layer) functions as a Model Context Protocol (MCP) server, designed to provide Large Language Models with robust HTTP API capabilities. It allows LLMs to perform a full range of HTTP operations (GET, POST, PUT, PATCH, DELETE, etc.) while ensuring security through its advanced secret management system, which uses templated substitution and URL-based restrictions for sensitive information. A standout feature is its ability to automatically generate ready-to-use tools from OpenAPI/Swagger specifications, simplifying complex API integrations and providing LLMs with a structured way to interact with external services.
