I used this to ask Opus 4.5 to intercept my network traffic to google maps, figure out how to decode it, and generate an STL file of the 3d map geometry. And it worked. Opus 4.5 is pretty amazing and used this MCP to great effect.
playwriter.dev is superb at reverse engineering private APIs
I ask opencode to track network requests while I do some actions. For example a trade on polymarket
Then I ask the LLM to see analyze the requests that were made and create an SDK for it
