Patent by Ouroboros Apps

get_patent and find_patent_citations are clearly distinct, but search_patents and search_prior_art both return ranked patent search results and could plausibly be selected for the same query. The descriptions hint at the difference (structured filters vs. an idea description), but the boundary is soft enough that an agent may pick the wrong one.

All four tools use a clean snake_case verb_noun pattern: find_patent_citations, get_patent, search_patents, search_prior_art. The convention is predictable and readable throughout.

Four tools is slightly thin but reasonable for a read-only US patent lookup server, where create/update operations are not meaningful. Each tool covers a distinct slice (record fetch, structured search, citations, prior art).

The surface covers the core read-only research loop: search, retrieve a record with claims/family/status, and traverse citations, plus an idea-to-search helper. Gaps are minor (no prosecution-history detail, no foreign/PCT coverage, no bulk export), and an agent can work around them.
