MCP capability inspector

This inspector reads what a server declares about itself and reports it. It never speaks MCP, never opens Streamable HTTP or SSE, and never calls a tool, so nothing you paste here can run. The safety hints come from tool annotations, and servers are honest or not on their own: an annotation claims, this page repeats the claim. Heuristic findings are word and character pattern matches written to make you read a tool before you trust it, not verdicts about intent, and the spec checks cover the required-field and pagination rules a paste can show, not a full conformance suite.
