OpenIndex Retrieval Plugin API MCP Server
detail.loadingPreview
Seamlessly integrate the OpenIndex Retrieval Plugin with your AI agents. This workflow exposes a powerful retrieval API as an MCP-compatible endpoint, allowing your AI to query and filter documents using natural language.
About This Workflow
This workflow bridges the gap between your AI agents and the OpenIndex Retrieval Plugin, enabling sophisticated document querying and filtering capabilities. The MCP trigger acts as a dedicated server endpoint, receiving natural language queries from your AI. These queries are then intelligently translated and sent to the OpenIndex API via an HTTP Request node. Leveraging $fromAI() expressions, parameters are automatically populated, ensuring a smooth and efficient interaction. The workflow is designed for native integration, returning API responses directly to your AI agent, making it an invaluable tool for AI-powered information retrieval.
