I want to look up open-access metadata for a DOI specifically using Unpaywall. Which dedicated tool performs this lookup?

The instructions your model reads when the skill loads.
Academic paper discovery and retrieval in this harness runs through the mcp__paper-search__* tools (the paper-search-mcp MCP server). Do not run the paper-search CLI or hand-write API requests — use these tools.
mcp__paper-search__search_papers — multi-source concurrent search with deduplication and DOI backfill. Prefer it for broad queries; one call covers many sources at once.mcp__paper-search__download_with_fallback — OA-first PDF download with a source-native → repository → Unpaywall fallback chain.mcp__paper-search__search_unpaywall — DOI-centric open-access metadata lookup.Per source the pattern is search_<source> / download_<source> / read_<source>_paper, with availability varying by source. Sources: arxiv, pubmed, biorxiv, medrxiv, iacr, semantic, crossref, openalex, pmc, core, europepmc, dblp, openaire, citeseerx, doaj, base, zenodo, hal, ssrn, openreview, google_scholar. ACM search is available without an API key. IEEE tools require PAPER_SEARCH_MCP_IEEE_API_KEY. Discover the current tool list rather than assuming every source supports full text.
Web of Science (search_wos) and Scopus (search_scopus, read_scopus_paper)
require runtime keys and explicit source selection; default/all searches never
include them. Scopus full-text retrieval requires explicit full_text=true;
respect its full_text, abstract_only, or unavailable status. Do not describe
an abstract or metadata record as retrieved full text.
get_citing_papers and get_referenced_papers provide bounded one-hop OpenAlex
lookups from a DOI or OpenAlex ID. Search caching is disabled by default; enabling
it persists queries and public results and is an operator choice. Use
get_search_cache_status to inspect it and clear_search_cache only when the
user asks to remove cached results. Clearing does not remove downloaded PDFs.
For speed, prefer a targeted set (search_arxiv, search_semantic, search_crossref) over multi-source search when the field is clear.
