"DOI" matching MCP servers:

Prevents citation hallucination by verifying academic citations against CrossRef's database of 150+ million publications before they can be mentioned, ensuring every citation includes a valid DOI.

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.

AI-powered research assistant MCP server for searching academic papers and answering research questions with DOI citations.

Provides LLMs with access to the DoiT API for managing cloud resources, analyzing costs, and handling support tickets via natural language.

Enables searching and retrieving articles from PLOS journals via Solr search, including by author, DOI, and recent publications.

Search and retrieve bioRxiv and medRxiv preprints — by DOI, date interval, or keyword — via MCP.

Supports historical queries with date filters, latest values, metadata loo

An MCP server for downloading academic papers from multiple sources using intelligent routing and year-aware priority selection. It enables users to retrieve metadata and download single or batch PDFs by DOI or URL.

Enables access to AWS documentation through natural language by fetching and converting documentation pages to markdown, searching AWS docs, and getting content recommendations for AWS service documentation.

Searches and fetches research datasets across Zenodo, DataCite (Dryad/Figshare/Dataverse/OSF), NCBI omics archives (GEO/SRA/BioProject), and the literature (PubMed/OpenAIRE) through one normalized model — deduplicating by DOI, expanding organism queries with NCBI Taxonomy synonyms, and bridging papers to the datasets they produced. Resolves citations and open-access full text, and downloads files.

Checks whether a citation has been retracted, corrected, or flagged with an expression of concern by querying Crossref — including retractions that Crossref backfills from the Retraction Watch database,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.
