If that same call also needs free text, a number, or another non-enumerable value, an LLM fills only those
We just ran Jev on our WebMCP benchmark.
The result: basically broke the benchmark.
Jev + Mercury 2.5 (a fast, low-cost LLM) using WebMCP solved 100% of the tasks at roughly 112× lower model cost than GPT-6 Astra using computer use with code execution. Compared to Astra using
In case you missed it - we have support for WebMCP in Chrome DevTools! 🎉
Find it inside the Application panel under "WebMCP" to easily debug your WebMCP tools!
Let us know what is missing and what should be improved!
