MCP health — MCP directory health check diagnostics

Official2 tools

by mcp-health

Diagnoses whether an MCP server is reachable, by live HTTP probe.

app.rowb.mcp-health/probe MCP Server

The app.rowb.mcp-health/probe Model Context Protocol (MCP) server diagnoses whether an MCP server is reachable by performing a live HTTP probe. It is used to determine reachability status over HTTP for the target MCP server endpoint.

🛠️ Key Features

Live HTTP probe to check reachability of an MCP server
Diagnoses whether the MCP server is reachable

🚀 Use Cases

Health checks for MCP server endpoints
Connectivity testing for MCP server availability via HTTP

⚡ Developer Benefits

Quick reachability diagnosis using an HTTP-based probe

⚠️ Limitations

Limited to diagnosing reachability via live HTTP probing (no other checks are described)

Captured live from the server via tools/list.

check_mcp_server

Diagnose whether an MCP server passes directory health checks. Runs five real HTTP probes (modern initialize, legacy initialize, anonymous tools/list, unauthorized tools/call, WWW-Authenticate/resource_metadata) and returns findings with fixes.
