How this service works
A hosted MCP server exposing utility tools any AI agent can call over HTTP — page-to-markdown, SEO audits, robots/sitemap checks, and more.
Output
Returns an object indicating whether the WebSocket URL is reachable and connectable, including connection status and any relevant error or response details from the handshake attempt.
Example use cases
Pre-deploy WebSocket health check
“Before I push my new release, can you verify that wss://staging.myapp.com/live is actually reachable and accepting WebSocket connections?”
Debugging a broken real-time feed
“My live data feed seems broken — can you test wss://feeds.myservice.io/stream and tell me if the WebSocket endpoint is up?”
Monitoring a third-party socket endpoint
“I rely on wss://api.thirdparty.com/events for my app — can you quickly check whether that WebSocket URL is currently reachable?”
Technical details
Endpoint
POSThttps://papacasper.com/mcp/pay/websocket_endpoint_checkWhen to prefer
Use this endpoint when you need a quick, lightweight check on whether a specific WebSocket URL is live and accepting connections — especially useful in CI/CD pipelines, pre-flight checks, or debugging real-time infrastructure. Prefer this over general HTTP uptime checkers when the target protocol is WebSocket (ws:// or wss://).
Side effects
- Invalid or malformed WebSocket URL (non-wss/ws scheme) — returns error
- Target host unreachable or DNS resolution failure
- Connection timeout if the server does not respond
- TLS/SSL certificate errors on secure wss:// endpoints
- Payment not accepted or insufficient USDC balance for the x402 call
