FAQ

Frequently asked questions

Do I need an API key?

No! CrossRef API is completely free and open. No authentication required. Just subscribe and start searching. Rate limit is 50 requests/second for polite pool.

What is a DOI?

DOI (Digital Object Identifier) is a unique alphanumeric string assigned to academic works. It provides a persistent link to the work's location online. Example: 10.1038/nature12373.

How can I filter search results?

Use the filter parameter with CrossRef filter syntax. Examples: 'type:journal-article' for journal articles only, 'from-pub-date:2024' for papers from 2024 onwards, 'has-abstract:true' for papers with abstracts, 'has-full-text:true' for open access papers.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
