openalex

openalex is a skill for Claude Code from oksure/openalex-research-mcp. It costs 100 tokens per session (1,288 once invoked), scanned A, original, MIT.

A skill for searching OpenAlex, a free catalog of research papers, authors, institutions, journals, and research topics.

In plain words
What is it for?
Finding papers and researchers, checking citation information, searching journals and institutions, and exploring research trends through the OpenAlex catalog.
Why use it?
It provides academic metadata searches without keeping a server running, while making clear that it does not provide paper full text or BibTeX citations.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is [`openalex-research-mcp`](../README.md) MCP server in this repo: instead of a.

Good fit Finding papers and researchers, checking citation information, searching journals and institutions, and exploring research trends through the OpenAlex catalog.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

openalex scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Status: active

OpenAlex is a free, open catalog of the global research system (477M+ works, 90M+ authors).

This skill is the lightweight, token-frugal counterpart to the openalex-research-mcp MCP server in this repo: instead of a persistent server with 31 structured tools, it shells out to a small CLI on demand, so it costs nothing while idle. Use the MCP server inside MCP clients (Claude Desktop, TypingMind); use this skill inside coding agents with shell access.

When NOT to use

  • arXiv/SSRN full-text search -> OpenAlex has metadata only, not full text
  • Reading a specific paper's full text -> fetch the DOI URL directly
  • Getting BibTeX citations -> use CrossRef (https://api.crossref.org/works/<DOI>)

Setup

The skill drives the openalex CLI bundled at skill/bin/openalex (zero dependencies, Python 3). Put it on your PATH:

chmod +x skill/bin/openalex
export PATH="$PWD/skill/bin:$PATH"
# Optional but recommended (faster "polite pool"):
export OPENALEX_EMAIL="[email protected]"
# Optional (premium): export OPENALEX_API_KEY="..."

Both env vars are optional — OpenAlex serves anonymous requests for free.

Core Patterns — openalex CLI

The CLI handles key/email injection, mandatory select= field trimming (full responses are 3x larger), abstract reconstruction from the inverted index, and DOI→W-id resolution. Add --json for shaped JSON output.

Search works (papers)

openalex works "supply chain network" -n 10
openalex works "structural estimation" --filter "from_publication_date:2024-01-01,cited_by_count:>10"
openalex works "<query>" --abstract        # include reconstructed abstracts

Get a specific work

openalex work 10.3982/ecta7743             # by DOI
openalex work W2070854196 --abstract --refs

Authors (two-step: search name → use the A-id; names are ambiguous, IDs are not)

openalex authors "daron acemoglu" -n 3
openalex author-works A5012301204 -n 10    # top works by citation
openalex experts "CRISPR gene editing" -n 5  # leading authors ON a topic, by h-index

experts resolves the topic to a topics.id and ranks authors who work on it by h-index (unlike authors, which name-matches) — use it to find field leaders.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openalex is a skill published in the GitHub repository oksure/openalex-research-mcp (50 stars, last pushed 2mo ago), licensed MIT. It adds 100 tokens to every session and 1,288 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
