Performs an automated synthetic health, protocol compliance, schema validation, and credential security audit on any remote Model Context Protocol (MCP) server. Use this tool when you need to comprehensively verify whether an external MCP server is reachable, measure round-trip latency, validate tool schemas against JSON Schema draft-07/2020-12 specifications, detect broken parameter definitions, and check for exposed API tokens or credentials. Returns a detailed markdown diagnostic report and structured status flags.

Validates JSON-RPC 2.0 protocol compatibility and version negotiation with a remote MCP server without executing a full synthetic vulnerability scan. Use this tool when you specifically need to test whether a remote server supports modern Stateless Core ("2026-07-28"), structured outputs ("2025-06-18"), icons metadata ("2025-11-25"), or legacy handshakes ("2024-11-05"), benchmark handshake latency, or inspect declared server capabilities and tool counts.

Generates dynamic SVG status badge links and Markdown embed snippets for an MCP Sentinel uptime monitor. Use this tool when you want to display the real-time operational status, protocol version, and uptime badge of a monitored MCP server directly inside a GitHub repository README, developer documentation, or status page.
