Frequently Asked Questions (FAQ) about Weaviate MCP Server and UBOS
Q: What is an MCP Server? A: MCP stands for Model Context Protocol. An MCP Server acts as a bridge, enabling AI models to access and interact with external data sources and tools by providing contextual information.
Q: How does the Weaviate MCP Server work? A: The Weaviate MCP Server is generated using the Postman MCP Generator. It exposes automated API tools to MCP-compatible clients, such as Claude Desktop or the Postman Desktop Application, allowing AI models to use these tools.
Q: What are the prerequisites for setting up the Weaviate MCP Server? A: You need Node.js (v18+ recommended) and npm installed on your system.
Q: How do I install the dependencies for the MCP Server?
A: Run npm install in the project’s root directory.
Q: How do I configure API keys for the MCP Server?
A: Update the .env file with the appropriate API keys for each workspace.
Q: How can I test the MCP Server?
A: Use the Postman Desktop Application to create an MCP request with the command node <absolute/path/to/mcpServer.js>.
Q: How do I connect the MCP Server to Claude Desktop?
A: Add a new MCP server configuration in the Claude Desktop settings, providing the absolute path to Node.js and mcpServer.js.
Q: Can I deploy the MCP Server using Docker? A: Yes, the MCP Server supports Docker deployment. You can build a Docker image and configure Claude Desktop to use the Docker container.
Q: What is UBOS, and how does it relate to the Weaviate MCP Server? A: UBOS is a Full-stack AI Agent Development Platform that enhances the capabilities of the Weaviate MCP Server by providing a comprehensive environment for building, deploying, and managing AI agents.
Q: What are the key features of UBOS? A: UBOS features include AI Agent Orchestration, Enterprise Data Connectivity, Custom AI Agent Development, and Multi-Agent Systems support.
Q: What if I encounter the error “fetch API not found”?
A: This error typically occurs when using an older version of Node.js. Ensure you are using Node.js v18+ or import node-fetch into each tool file.
Q: What do I do if tool calls are not working in Claude? A: Verify that you are using an absolute path to a Node.js version that is v18+ in the Claude Desktop settings and that the MCP server is turned on.
Q: How do I add new tools to the MCP Server?
A: Generate new tools using the Postman MCP Generator, copy the generated code into the tools/ folder, and update the tools/paths.js file.
