How do you test that an MCP server change didn't break your agents?
For folks running MCP servers with a team (internal or third-party ones): when you update a server or change a tool, how do you know you didn't silently break something downstream?
Trying to sort out my own workflow and curious what others actually do in practice — CI checks? manual testing in the client? contract tests on the tool schemas? just ship and find out?
Also interested in how you catch it when a server degrades over time (gets slower/flakier) vs. hard-breaks. Do you find out right away or days later?
