Scored across 4 tools
Each tool has a clear role: get_api retrieves by slug, list_apis pages all inventory, search_apis does natural-language discovery, and prepare_api_execution sets up payment. Search and list are related but descriptions distinguish their use cases well. Minor ambiguity exists between get_api and list_apis for simple retrieval, but slug-based lookup clarifies the boundary.
All tool names follow a consistent verb_noun pattern: get_api, list_apis, search_apis, prepare_api_execution. Naming is predictable and clearly indicates the action taken.
Four tools is well-scoped for an API discovery and execution preparation server. Each tool represents a distinct step in the workflow: discover, retrieve, search, and prepare.
The server covers the core consumer workflow: finding APIs via search/list/get and preparing paid executions. The actual execution call is deliberately externalized behind the payment gate, so no tool is strictly missing. A minor gap is the lack of a direct search refinement or pagination control, but it is not essential.
