Free tier, no signup. ## Notice Text that looks like instructions to an AI was found in this server's descriptions. This is a pattern match, not a verdict. ## Connect - streamable-http: `https://preflight.allthepossibles.com/mcp` ## Tools (as reported by the server, not verified) - `scan\_mcp\_server`: Check an MCP server for real risk signals before trusting it: unauthenticated transport, capability overreach \(filesystem/shell/credential access with no scoping\), and known-bad signatures. Pass a live server URL, or a manifest of tool definitions if the server isn't reachable over HTTP. Semantic pr - `scan\_content`: Check a document or web page for hidden instructions before an agent reads, summarizes, or acts on it: invisible Unicode, obfuscated payloads, and \(on Pro\) a semantic pass for prompt-injection phrasing aimed at the model instead of the human reader. Pass either a URL to fetch, or raw text you alread - `scan\_extension`: Check a VS Code extension or a Claude Skill before installing or trusting it. For a VS Code extension \(which runs with full Node.js access and no permission model to scope\): publisher domain-verification status weighed against install count, and known-bad-signature checks on its description. For a C - `check\_output`: Check a structured output you're about to return or act on for degenerate-answer patterns a schema check can't see: invalid JSON, a placeholder value \('TBD', 'N/A', 'unknown'\) where a real answer should be, an array of byte-identical items \(a common symptom of a loop that never advanced\), or an expe Measured by MCP Station.
