MCP tooling
AXE
MCP apps that agents actually finish — before a client Operator has to fight the interface.

Design. Test. Score.
A wide tool surface looks complete and then fails in production. AXE is how you find that before the client does.
Design
Shape MCP apps around how agents actually call tools — not a dump of every endpoint you have.
Test
Run the server the way an agent will: tool lists, follow-up calls, recovery after a miss.
Score
Measure whether the interface is usable before a client’s Operator or your own loop has to fight it.

AI/AX design principles live in the dashboard
How to cut visible tools with dynamic toolkits and sub-agents, how to pass context without UUIDs, how errors should read so an agent can recover — that write-up is for certified partners, under Platform → MCP.
