Repository instructions for an MCP server that searches OpenAlex, an open catalog of research papers, authors, institutions, journals, and related research data.

In plain words
What is it for?
Use them when developing or maintaining tools that search, filter, retrieve, group, or autocomplete OpenAlex research entities.
Why use it?
They explain the server’s research domain, required development setup, and the need to resolve names to stable IDs before filtering results.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is cyanheads/openalex-mcp-server's own configuration. It tells Claude Code, Codex and OpenCode how to work on openalex-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openalex-mcp-server configures →

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-mcp-server AGENTS.md scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

70% identical to obsidian-mcp-server AGENTS.md — 367 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 366 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Developer Protocol

Server: openalex-mcp-server Version: 0.7.10 Framework: @cyanheads/mcp-ts-core ^0.12.5 Engines: Bun ≥1.3.0, Node ≥24.0.0 MCP SDK: @modelcontextprotocol/server ^2.0.0 Zod: ^4.5.4

Read the framework docs first: node_modules/@cyanheads/mcp-ts-core/CLAUDE.md contains the full API reference — builders, Context, error codes, exports, patterns. This file covers server-specific conventions only.


Domain

OpenAlex is a fully open catalog of the global research system — 270M+ works, 90M+ authors, 100K+ sources. CC0 data, no API key required (email address optional for polite pool access).

Entity types: works, authors, sources, institutions, topics, keywords, publishers, funders. All share a uniform API (list/filter, search, get-by-ID, group-by, autocomplete).

Critical workflow: Names are ambiguous, IDs are not. Always resolve names to IDs first via openalex_resolve_name before using them in filters.

Reference docs: README.md covers the current tool and prompt surface; docs/tree.md shows the current repository layout.

MCP Surface

Type Name Purpose
Tool openalex_search_entities Search, filter, sort, or retrieve by ID
Tool openalex_analyze_trends Group-by aggregation for trends/distributions
Tool openalex_resolve_name Name-to-ID resolution via autocomplete
Tool openalex_get_citation_graph One-hop citation graph traversal (cites/cited_by/related_to)
Tool openalex_describe_fields List valid filter/group_by/select field names per entity type
Prompt openalex_literature_review Guided systematic literature search workflow
Prompt openalex_research_landscape Quantitative research landscape analysis

No resources — entity lookups need select for payload control, which fits tools better than URI templates.

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.
