Openstatus MCP Health Checker Catch handshake failures HTTP pings completely miss

Openstatus MCP Health Checker

Openstatus MCP Health Checker is a free, browser-based tool that validates Model Context Protocol server health by performing the complete JSON-RPC handshake. It tests the three critical initialization steps—initialize, ping, and tools/list—to ensure your MCP server is ready for AI clients like Claude Desktop, Cursor, and Continue.

Product Highlights

• Complete MCP Handshake: Runs the full initialize, notifications/initialized, ping, and tools/list sequence that real AI clients use
• Zero Setup Required: No installation, no signup, no account—test any MCP server directly from your browser in under 30 seconds
• Detailed Diagnostics: Inspect exact JSON-RPC requests and responses with per-step latency, protocol version, and session ID capture
• OAuth-Aware Auth Handling: Automatically parses RFC 9728 resource metadata on 401 responses and surfaces the correct authorization server
• Privacy-First Design: All checks run in your browser session; only explicitly shared reports are stored (expiring after 7 days)

Use Cases

• Pre-Deployment Validation: Verify your MCP server implementation before shipping to production or sharing with users
• Integration Debugging: Trace exactly where handshakes fail—whether DNS issues, HTML responses, missing methods, or authentication problems
• OAuth Configuration Testing: Confirm your protected MCP server correctly implements RFC 9728 and returns proper WWW-Authenticate challenges
• Client Compatibility Assurance: Ensure your server negotiates protocol version 2025-06-18 and exposes tools as expected by Claude, Cursor, and other MCP clients

Target Audience

Openstatus MCP Health Checker is designed for developers building, deploying, or integrating MCP servers—including backend engineers, DevOps teams maintaining AI infrastructure, and solution architects validating third-party MCP endpoints before production adoption.
