XLUXX

XLUXX is a trust intelligence platform designed to assess and monitor the reliability and security of Model Context Protocol (MCP) servers, which are used by AI assistants to connect with external tools and services. The platform addresses the challenge of evaluating the safety and trustworthiness of a rapidly growing ecosystem of MCP servers, many of which may expose vulnerabilities such as credential leaks, prompt injection, or data exfiltration.

At its core, XLUXX operates a comprehensive trust scoring system that continuously crawls both official and community MCP registries to discover new servers. Every six hours, it fingerprints each discovered server, extracting details about declared capabilities, authentication methods, tool descriptions, and supported transport protocols. The platform then conducts live behavioral tests to validate server responses, check for unexpected outbound connections, and compare actual outputs with documented claims. These findings inform a multi-factor trust score, which incorporates metrics such as uptime, reliability, presence of known vulnerabilities, PII detection in outputs, behavioral consistency, and registry provenance.

The results are made available through a public REST API that delivers real-time trust scores for over 15,000 MCP servers and more than 7,200 individual tools. The API supports single and bulk queries, provides historical score timelines, and can send webhook alerts when a server's trust status changes. XLUXX also publishes a public leaderboard of the most trusted and most-used servers, updated in real time, and performs daily security audits to keep its catalog current.

XLUXX is intended for developers building AI pipelines, enterprises deploying AI agents, and security teams auditing AI usage. Developers can use the platform to programmatically evaluate MCP servers before integrating them into production workflows, while enterprises and compliance teams benefit from audit trails, provenance data, and continuous monitoring. Security professionals can map MCP server exposure and receive alerts on trust score changes. The platform offers 100 free API requests per day, allowing users to score MCP servers instantly. XLUXX positions itself as a neutral trust layer for the AI ecosystem, analogous to a certificate authority, aiming to make AI agent integrations safer and more reliable.
