# MCP Registry Validator — Check Endpoints Actually Resolve MCP server

Check an MCP endpoint resolves: liveness, live tool list, schema drift. Free.

## Setup notes
- Remote endpoint: https://mcp-uptime.theopslog.workers.dev/mcp

## Tools
- check_mcp_endpoint - Probe an MCP endpoint right now: is it alive, which transport it speaks, how many tools it exposes, and whether its tool schema changed since the last check. Use before depending on a third-party MCP server. Endpoint: https://mcp-uptime.theopslog.workers.dev/mcp
- get_uptime - Uptime history for an MCP endpoint over the last N days (max 30), with incident windows. Reads stored history; does not probe. Endpoint: https://mcp-uptime.theopslog.workers.dev/mcp
- get_known_tools - The tool list last observed at an MCP endpoint, with the timestamp of the most recent schema change. Reads stored history; does not probe. Endpoint: https://mcp-uptime.theopslog.workers.dev/mcp
- check_schema_drift - Probe an MCP endpoint and diff its tool schema against the last stored snapshot: tools added, removed, or whose description/inputSchema changed. Schema drift fails quietly mid-run, which is why it is worth checking. Endpoint: https://mcp-uptime.theopslog.workers.dev/mcp
