Hal

HAL is a Model Context Protocol (MCP) server that enables Large Language Models (LLMs) to interact with web APIs via HTTP requests in a secure, controlled manner. It features automatic tool generation from OpenAPI/Swagger specifications, robust secret management (with namespacing and redaction), and granular configuration for environment security and access whitelisting/blacklisting. HAL is ideal for teams looking to securely extend the capabilities of MCP-compatible AI clients (like Claude Desktop) with real-time API integration and tool generation.
