"DOI" matching MCP servers:

MCP server providing U.S. college ROI data (30-year NPV, major ROI, best-value rankings, and out-of-state tuition penalty) by wrapping a free, keyless API.

MCP server that turns DOI, URL, or paper titles into structured Markdown full-text with metadata and assets, enabling AI agents to read beyond abstracts.

Conceptual document splitter that parses PDF/DOCX into study-sized chunks with safe-cut constraints, verified output, and bilingual study indexes, exposed as MCP tools for AI coding assistants.

Enhances large language models with competitive programming knowledge by leveraging OI-Wiki content through vector search, allowing models to retrieve relevant algorithms and techniques.

Enables users to check whether a chosen university subscribes to a given journal or paper — via search, DOI, journal title, database, and journal-package queries — returning library holdings plus clickable links the user opens themselves. It supports multiple schools through a picker panel and only ever inspects holdings, never downloading full text.
