- Include comprehensive documentation for body structures and auth types in Zod descriptions
- Fix MCP update_http_request to merge partial updates with existing data to prevent FK constraint violations
- Fix Zod imports from 'zod/v4' to 'zod' to match installed version
- Add uncaughtException handler to plugin runtime to prevent individual plugin crashes from crashing entire runtime
