Questions
- Which uses fewer tokens, agent-device or Mobile?
- Mobile: its tool definitions take about 6,035 tokens per turn against 36,388 for agent-device (6.0× more). Tool definitions are resent on every model turn.
- Do agent-device and Mobile have the same tools?
- No tool names overlap: agent-device has 59 tools and Mobile has 34.
- Are agent-device and Mobile hosted or local?
- agent-device: local (stdio). Mobile: local (stdio).
Token counts use the o200k tokenizer on each server's tool definitions as an agent receives them; clients that load tools lazily pay less. Prices are Claude Sonnet 5.5 input at $2/MTok. Want to check one yourself? Run npx mcpskillhub test <package> — how it works.
