WhichModel

Each tool has a clearly distinct purpose with no overlap: check_price_changes monitors historical pricing, compare_models compares specific models, estimate_cost projects workload costs, find_cheapest_capable filters by capabilities, get_pricing provides raw filtered data, and recommend_model offers task-based recommendations. The descriptions explicitly differentiate use cases and direct users to the appropriate tool.

All tool names follow a consistent verb_noun pattern using snake_case (e.g., check_price_changes, compare_models, estimate_cost). The naming is predictable and readable throughout, with no deviations in style or convention.

With 6 tools, the server is well-scoped for LLM model selection and pricing analysis. Each tool serves a unique function in the domain, covering monitoring, comparison, estimation, filtering, data retrieval, and recommendation without being overly sparse or bloated.

The toolset provides complete coverage for LLM model selection and cost management: it includes monitoring (check_price_changes), comparison (compare_models), cost estimation (estimate_cost), capability-based filtering (find_cheapest_capable), data lookup (get_pricing), and recommendation (recommend_model). There are no obvious gaps, and the tools work together to support end-to-end workflows.
