对注意力有显著影响（占 128k 上下文窗口的 3.40%）
这是每次将服务器的工具加载到模型上下文窗口时所消耗的大致 token 数。数值越高，可用于其他任务的注意力就越少。

🟢catalog_search(query, provider_slug, category_slug, page, page_size)
Find canonical model slugs, context limits, and provider prices. Optional provider_slug filters availability, not the provider in bestOffer. bestOffer is selected for 10M input + 2M output tokens; use offer_compare for your workload. Follow pagination.hasMore.

}🟢model_detail(model_slug)

}🟢offer_compare(model_slugs, provider_slugs, input_tokens, output_tokens)
Rank current provider offers for up to five canonical model slugs by the USD cost of your input/output token workload. Input tokens are uncached. Estimates use base-context rates and exclude long-context tiers, cache writes, batch discounts, and free-tier quotas. provider_slugs restricts the ranked offers.

}🟢execute(code)
Run a JavaScript async function in an isolated sandbox, composing catalog_search, model_detail, offer_compare, benchmark_results, provider_list, and benchmark_list as catalog.* methods. Return a small JSON value. Example: async () => { const page = await catalog.catalog_search({query: 'claude', page_size: 5}); return page.data.models.map(m => ({slug: m.slug, prices: m.bestOffer?.prices})); }. No network, secrets, or database binding is exposed. Shared worldwide execution budgets: 100 per UTC minute and 5000 per UTC day. Limits: 30 executions per client per minute (IPv6 /64), 20 catalog calls and read units (offer_compare uses 5), at most two concurrent calls, 5 seconds wall time, 50ms sandbox CPU, 32KiB code, 64KiB JSON output. JavaScript only; no imports or TypeScript syntax. Use /mcp?mode=code for only search + execute.
