How to Test MCP Server Changes Without Breaking Agents
Deversatilist · reddit · 2026-07-06
A developer asks: when a team updates an MCP server or modifies a tool, how to confirm it hasn't silently broken downstream agents? In practice, do people rely on CI checks, manual client testing, contract testing on tool schemas, or 'ship first, fix later'? Also, how to catch server 'degradation' (slowness/instability) over time rather than hard failures — is it detected immediately or days later?
