Looks things up and changes nothing. Claude Code: allow.

### `openalex_analyze_trends`

- The name "openalex_analyze_trends" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Aggregate OpenAlex entities into groups and count them. Use for trend analysis (group works by publication_year), distribution analysis (group by oa_status, type, country), and comparative analysis (group by institution or topic). Combine with filters to scope the analysis. Returns up to 200 groups per page — use cursor pagination for fields with many distinct values.
```

### `openalex_describe_fields`

- The name "openalex_describe_fields" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List valid field names for an OpenAlex entity type and context (filter, group_by, or select). Use proactively before constructing a filter or group_by to avoid invalid-field 400 errors. Pass `query` to rank the list by name similarity — useful when you have a partial or guessed field name. Ranking never drops a field: the full list comes back either way.
```

### `openalex_get_citation_graph`

- The name "openalex_get_citation_graph" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Walk the citation graph one hop from a seed work. Direction picks the edge: incoming citations (`cites`), the seed's own references (`cited_by`), or OpenAlex's algorithmically-related works (`related_to`). Note: `direction` follows OpenAlex's filter convention, which inverts the common English reading — `cites` returns works that cite the seed; `cited_by` returns works the seed cites. Results use the works schema; combine with filters/sort to narrow further. Responses cap at 64,000 bytes per surface unless the least a call can return is larger (`over_budget`); `omitted` and `windows` give the openalex_search_entities calls that continue a cut.
```

### `openalex_resolve_name`

- The name "openalex_resolve_name" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve a name or an identifier to an OpenAlex ID. ALWAYS use this before filtering by entity — names are ambiguous, IDs are not. A name returns up to 10 autocomplete matches with disambiguation hints. An identifier — OpenAlex ID, DOI, ORCID, ROR, PMID, or ISSN, bare or in URL form — resolves directly to the record it addresses instead of running a name search. Short names share the bare OpenAlex ID shape (keyword p53 reads as publisher ID P53), so a bare OpenAlex ID that resolves nothing is searched as a name next. Two identifiers can address more than one entity type: a ROR names an organization's institution, funder, and publisher records alike, so it returns each one that exists (institution first) unless entity_type picks one of those three; and a Crossref Funder Registry DOI (10.13039/…) resolves to the funder unless entity_type is works. A PMCID is recognized as well, bare or as a PubMed Central URL, but OpenAlex indexes no PMCIDs, so it resolves nothing — pass the work's PMID or DOI instead.
```

### `openalex_search_entities`

- The name "openalex_search_entities" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search, filter, sort, or retrieve by ID. Covers all OpenAlex entity types (works, authors, sources, institutions, topics, keywords, publishers, funders). Pass `id` to retrieve a single entity. Otherwise, use `query` and/or `filters` for discovery. Supports keyword search with boolean operators, exact phrase matching, and AI semantic search. Use openalex_resolve_name to resolve names to IDs before filtering. Searches and ID lookups return a curated set of fields by default; pass `select` to override with specific fields, or `["*"]` for the full record. Responses cap at 64,000 bytes per surface unless the least a call can return is larger (`over_budget`); `omitted` and `windows` give the calls that continue a cut, and `slice` pages a long array.
```
