Honestly, MCPJam has become one of the best and most useful dev tools for MCPs. Having all these features in one place makes the whole workflow way smoother!!
What kind of tests do you recommend running before pushing an MCP server into production?
Congrats on the launch, Prathmesh! As a solo developer building hyper-lightweight web apps from scratch (pure PHP and vanilla JS), I am obsessed with reducing friction and tracking exactly how features behave. The concept of 'Swarms' to simulate ifferent user goals is brilliant. When building standalone tools, testing user flow behavior without heavy framework overhead is a massive challenge. Reducing the abstract evaluation of AI-native interactions into repeatable ests is definitely a game-changer for independent makers.

@marcophp glad you like Swarms! At Asana I was struggling to generate the "right" prompts to throw into our evals when production o11y gave us so little user intent and we resorted to best practiec checklists. Being able to spin up agents to act like my users with clear goals and just see how they prompt and perform across clients is fun to find those patterns for sure
