OpenAlex is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Query the OpenAlex scholarly catalog of 270M+ publications, authors, institutions and concepts.

# openalex_resolve_name, openalex_search_entities, openalex_analyze_trends and 2 more
OpenAlex costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, read from the address; if the publisher says otherwise, swap that one word.
claude mcp add --scope user --transport http openalex-caseyjhand-com-openalex-mcp https://openalex.caseyjhand.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
5 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

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, PMCID, or ISSN, bare or in URL form — resolves directly to the one record it addresses, and needs no entity_type.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| entity_type | string | no | Entity type to search. Omit for cross-entity search (useful when entity type is unknown). Not applied when query is an identifier — an identifier determines its own entity type. |
| query | string | yes | Name or partial name to resolve. Also accepts an identifier, bare or in URL form — OpenAlex ID ("W2741809807", "F4320332161"), DOI ("10.1038/nature12373"), ORCID ("0000-0002-1825-0097"), ROR ("https:/ |
| filters | object | no | Narrow autocomplete results with filters. Example: restrict to a specific country or publication year range. Applies to name queries only — an identifier already addresses a single record. |
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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| entity_type | string | yes | Type of scholarly entity to search. |
| id | string | no | Retrieve a single entity by ID. Supports: OpenAlex ID ("W2741809807"), DOI ("10.1038/nature12373"), ORCID ("0000-0002-1825-0097"), ROR ("https://ror.org/00hx57361"), PMID ("12345678"), PMCID ("PMC1234 |
| query | string | no | Text search query. Supports boolean operators (AND, OR, NOT), quoted phrases ("exact match"), wildcards (machin*), fuzzy matching (machin~1), and proximity ("climate change"~5). Omit for filter-only q |
| search_mode | string | no | Search strategy. "keyword": stemmed full-text (default). "exact": no stemming, matches individual words (use quoted phrases for multi-word exact match). "semantic": AI embedding similarity (max 50 res |
| filters | object | no | Filter criteria as field:value pairs. AND across fields (multiple keys). OR within field: pipe-separate ("us|gb"). NOT: prefix "!" ("!us"). Range: "2020-2024". Comparison: ">100", "<50". AND within sa |

| select | array | no | OpenAlex top-level field names to return. Always returned: id, display_name — additional fields you list are appended. A curated default per entity type applies to both searches and single-entity |
| per_page | integer | no | Results per page (1-100). Default 25. Semantic search caps at 50 — when search_mode="semantic", set per_page ≤ 50 (also subject to a 1 req/sec rate limit upstream). The cap applies to searches only; a |
| cursor | string | no | Pagination cursor from a previous response. Pass to get the next page. |
| sample | integer | no | Return a random sample of this many entities matching the filters (1-100). Single page only — pagination via cursor is not supported with sampling. Overrides per_page. Useful for unbiased explorat |
| seed | string | no | Deterministic seed for sample. Same seed + same filters = same results — pass when reproducibility matters. Has no effect without sample, and a search that passes it alone is rejected. |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| entity_type | string | yes | Entity type to aggregate. |
| group_by | string | yes | Field to group by. Works examples: "publication_year", "type", "oa_status", "primary_topic.field.id", "authorships.institutions.country_code", "is_retracted". Authors: "last_known_institutions.country |
| filters | object | no | Filter criteria (same syntax as openalex_search_entities filters). Narrows the population before aggregation. For full-text within filters, use abstract.search, title.search, or default.search — there |
| include_unknown | boolean | no | Include a group for entities with no value for the grouped field. Hidden by default. |
| per_page | integer | no | Maximum groups per page (1-200). Default 200 (the upstream cap). A real top-N knob when order is count (the default) — reduce to return only the highest-count groups. |
| order | string | no | Sort order for groups. Omit or pass "count" (default) to return the top-N groups by count descending — no further pages. Pass "key" to enumerate all distinct values in key-ascending order with cursor |
| cursor | string | no | Pagination cursor from a previous response. Only relevant when order is "key" — count-descending results have no next page. Pass the next_cursor from the previous response to advance. |
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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| seed_id | string | yes | Seed work identifier. Accepts OpenAlex ID ("W2741809807"), DOI ("10.1038/nature12373" or full URL), PMID, or PMCID. Use openalex_resolve_name first if you only have a title. |
| direction | string | yes | "cites": works that cite seed_id (incoming citations). "cited_by": works that seed_id cites (its reference list). "related_to": OpenAlex algorithmically-related works (~8-30 typical, may be empty for |
| filters | object | no | Additional filters to narrow the graph, same syntax as openalex_search_entities. Example: publication_year=">2020", is_oa="true". Do not include cites/cited_by/related_to — those are set by the `direc |

| select | array | no | OpenAlex work field names to return. Always returned: id, display_name. Defaults to the curated works select if omitted. |
| per_page | integer | no | Results per page (1-100). Default 25. |
| cursor | string | no | Pagination cursor from a previous response. Pass to get the next page. |
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 narrow the results by name similarity — useful when you have a partial or guessed field name.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| entity_type | string | yes | OpenAlex entity type to list fields for. |
| context | string | yes | Field usage context. "filter": fields accepted in the filter param. "group_by": fields accepted in group_by — a subset of the filter set (raw date and *.search fields are excluded; they cannot be grou |
| query | string | no | Optional partial or guessed field name to rank results by similarity. Pass the field you tried (e.g. "funder") to get the closest matches first. Omit to return all fields for the entity_type + context |

- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install OpenAlex or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.7.9.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish OpenAlex can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
