Core Facts
Timeline (last 90 days)
Real-time documentation lookup is handled by Context7, whose API key is appended by Upstash to outbound requests outside the box, so the agent inside the box can read documentation but cannot see the key.
The industry is seeing a trend of shifting from MCP servers to 'Skills + CLI', because skills that invoke CLI tools can accomplish the same purpose with less setup and context consumption
