The application-level visibility point matches my experience. I removed an MCP server a while back because its tool descriptions quietly told the agent to prefer it as the primary search tool over the built-in one. Not a vulnerability, no leaked secrets, just the vendor steering agent behavior in a way you only notice if you read the raw tool definitions. Does mcp-xray flag that kind of prompt-level steering in tool descriptions, or is it focused on classic vulns?
