Scored across 11 tools
Most tools have clearly distinct purposes, such as account_info, list_leads, email_verifier, and the three enrichment variants. The main ambiguity is between domain_search and email_finder, as both can locate emails for a domain, though one is broad search and the other is targeted person lookup.
Tool naming is inconsistent: some use verb_noun (create_lead, list_leads), some use noun_verb (domain_search), some use noun_noun (email_finder, email_count), and one is a bare verb (discover). This mixed pattern makes the tool surface harder to predict.
11 tools is well-scoped for a Hunter MCP server. Each tool covers a meaningful capability of the Hunter API, including account info, lead management, email discovery, verification, enrichment, and company search, without excessive redundancy.
The server covers most of the Hunter domain well, including search, enrichment, verification, and lead creation. However, lead management is incomplete: create_lead and list_leads exist, but there are no update or delete lead tools, leaving an obvious lifecycle gap.
