Frequently Asked Questions (FAQ) about UBOS MCP Server
Q: What is the MCP Server? A: MCP (Model Context Protocol) Server is a secure URL fetching tool designed for AI agents and applications. It allows AI models to access and interact with external data sources and tools safely.
Q: What are the key features of the MCP Server? A: Key features include secure URL fetching, domain resolution, private/internal IP check, redirect handling, custom HTTP methods and headers, an allowlist for trusted domains/IPs, and restriction to HTTP and HTTPS schemes.
Q: How does the MCP Server ensure security? A: The MCP Server ensures security by preventing access to private/internal IPs, using an allowlist for trusted domains/IPs, restricting to HTTP and HTTPS schemes, and setting SNI to match the hostname for HTTPS connections.
Q: What is the purpose of the allowlist? A: The allowlist is a list of trusted domains and IPs that the MCP Server is permitted to access. This prevents access to potentially malicious or untrusted resources.
Q: How does the MCP Server handle redirects? A: The MCP Server handles redirects up to a certain limit (typically 3) to ensure that AI agents can follow links to the correct destination without getting stuck in redirect loops.
Q: Can I use custom HTTP methods with the MCP Server? A: Yes, the MCP Server supports custom HTTP methods and headers, allowing for flexible interaction with web servers and APIs.
Q: What is SNI, and why is it important? A: SNI (Server Name Indication) is a feature that allows the MCP Server to present the correct SSL certificate for HTTPS connections. This prevents man-in-the-middle attacks and protects against data interception.
Q: What is FastMCP, and how does it relate to the MCP Server? A: FastMCP is a high-performance library for secure URL fetching that the MCP Server is built upon. It provides the underlying infrastructure for secure communication and efficient data transfer.
Q: How do I install the MCP Server in my UBOS environment? A: You can install the MCP Server from the UBOS Asset Marketplace. Simply locate the asset and click the install button to add it to your UBOS environment.
Q: Can I use the MCP Server with AI agents developed outside of the UBOS platform? A: While the MCP Server is designed to integrate seamlessly with the UBOS platform, it can potentially be used with external AI agents, provided they can interface with the server’s API.
Q: What kind of logging and monitoring is available with the MCP Server? A: The MCP Server provides logging of requests and security-related events, which can be monitored to identify potential issues or threats.
Q: Is there a limit to the size of the content that can be fetched by the MCP Server? A: While there isn’t a hard-coded limit, extremely large content may impact performance. It’s recommended to test and optimize for your specific use cases.
Q: What kind of support is available for the MCP Server? A: UBOS provides documentation, tutorials, and community support to help you get started with the MCP Server. You can also contact UBOS support for assistance with any issues or questions.
Q: How do I update the MCP Server to the latest version? A: You can update the MCP Server through the UBOS Asset Marketplace. The platform will notify you when updates are available.
