A monitoring service for Model Context Protocol servers that performs real handshakes, detects tool-list drift, runs synthetic calls, and sends failure alerts.

Why it surfaced

mcptrax addresses a specific failure mode in the emerging MCP ecosystem: a server can return HTTP 200 while its handshake, tool list, or tool calls are broken. Its checks follow the sequence a real client uses, with a free single-server plan and a $20/month Pro tier adding minute-level checks, assertions, Slack, and webhook alerts.
