"DOI" matching MCP servers:

Serves as an MCP server that resolves academic DOIs to canonical identifiers and generates BibTeX records via CrossRef.

Enables resolving academic DOIs to canonical identifiers and generating BibTeX records via CrossRef, and can be integrated into MCP-compliant clients for automated research workflows.

Enables retrieval of academic literature metadata via DOI or search using the Crossref REST API.

Checks whether a citation has been retracted, corrected, or flagged with an expression of concern by querying Crossref — including retractions that Crossref backfills from the Retraction Watch database, which publishers often never record in their own metadata. Lets an AI agent verify a DOI, or every DOI in a reference list, before using it in research or writing.

An MCP server that resolves paper requests (DOI, arXiv, etc.), checks a local store, fetches open-access PDFs, and returns request IDs. It integrates with acatome-extract for ingestion and provides tools for submission, status, update, and file upload.

Enables looking up free-to-read versions of scholarly papers by DOI and searching article titles for Open Access matches via the Unpaywall API.

Hosted MCP server for antiquarian first-edition identification and New Mexico book-donation logistics. 12 tools over a CC-BY, DOI-cited dataset of 6,700+ titles and 870 publisher conventions.

Enables AI clients to search for academic papers, fetch metadata by DOI, retrieve open access PDF links, and extract full text from research papers using the Unpaywall API. Provides seamless access to scholarly literature for research and analysis tasks.

Enables querying open-access availability of scholarly articles via Unpaywall API, including DOI lookup, title search, and citation export.

MCP server for downloading academic papers from DOI or title, resolving references, and generating citations. Supports batch downloads, multiple mirrors, and optional Unpaywall integration.

An MCP server for the INSPIRE-HEP API, enabling literature search, author lookups, DOI/arXiv/ORCID resolution, citation export, and bibliography generation with configurable detail levels.

A universal paper downloader MCP that probes providers by DOI/identifier, downloads to a short-lived staging area, validates PDFs, and cleans up, while leaving final storage and management to the calling project.

Enables AI agents to search and retrieve academic papers from China National Knowledge Infrastructure (CNKI), supporting various search types including subject, keyword, author, and DOI lookups.

A Model Context Protocol server that enables querying the Crossref API to search for academic publications by title, author, or DOI, returning structured metadata about scholarly works.

Enables agents to search, retrieve, and list open-licensed documents with verifiable provenance, attaching sha256, DOI, and OpenTimestamps proof to every response.

Enables querying a single academic paper by DOI, PMID, or arXiv ID to retrieve its open-access copies, licenses, linked datasets, code, citations, and retraction status from multiple scholarly sources in one call.

Provides 40 tools to Claude for Wikipedia citation analysis, edit history, and DOI/ISBN annotation, enabling citation quality scoring and metadata enrichment without leaving the chat.

Enables querying concluded U.S. Department of Labor Wage & Hour Division enforcement cases, including employer search, case histories, back-wage totals, and dataset coverage.

Enables searching DataCite datasets and software, fetching DOI metadata, tracing relations, and formatting citations via MCP, supporting stdio or Streamable HTTP.

Enables AI agents to search CERN's open research data repository and retrieve records, files, and curated communities by DOI or keyword, covering datasets, software, papers, and presentations. Works keyless over HTTP or as a local stdio server, with no account required for initial calls.
