Frequently Asked Questions (FAQ) about MCP Server

Q: What is MCP Server? A: MCP Server, or Model Context Protocol Server, is a tool designed to unify multiple webhook endpoints into a single configuration, simplifying knowledge base management and querying for AI models and agents.

Q: How does MCP Server work? A: It works by allowing you to register different knowledge base (webhook endpoint) URLs, optionally with a description and API key. You can then query these sources individually or all at once, and the tool aggregates the results for you.

Q: What are the prerequisites for using MCP Server? A: You need Go, Python 3.6+, Anthropic Claude Desktop app (or Cursor or Cline), and UV (Python package manager).

Q: Which AI clients are compatible with MCP Server? A: MCP Server is designed to work seamlessly with Claude, Cursor, and Cline.

Q: Can MCP Server be used on Windows? A: Yes, MCP Server is compatible with Windows. However, go-sqlite3 requires CGO to be enabled, and you’ll need a C compiler installed.

Q: How do I configure the endpoints? A: You need to modify or create a knowledge_document_sources.json file with the details of your webhook endpoints.

Q: What if I encounter permission issues when running uv? A: Ensure that uv is added to your PATH or use the full path to the executable.

Q: How do I add a new knowledge document source? A: Use the add_new_knowledge_document_source tool, providing the URL, description, and API key (if required).

Q: How do I list all registered knowledge sources? A: Use the list_knowledge_document_sources tool to display all registered sources and their details.

Q: How do I query a specific knowledge source? A: Use the query_knowledge_base tool, specifying the query and the source IDs.

Q: Where can I find example API schemas for knowledge endpoints? A: Check the sample_endpoint folder in the repository for references on supported API schemas.

Q: What is the purpose of the mcp.json file in Cursor? A: The mcp.json file is used to configure Cursor AI with your MCP settings, including the tool’s name, version, description, and available tools.

Q: How can I verify if MCP is properly configured in Cursor? A: Use the command fastmcp check mcp.json to check the configuration and fastmcp list to list available tools.

Q: Can I load custom knowledge sources from a different file than knowledge_document_sources.json? A: Yes, you can specify a custom path in the DOCUMENT_SOURCES_PATH environment variable.

Q: What is UBOS and how does MCP Server integrate with it? A: UBOS is a full-stack AI Agent Development Platform designed to bring AI Agents to every business department. The MCP Server can be integrated to help UBOS connect to enterprise data and build custom AI Agents.
