Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
PYEUROPEPMC_MCP_LOG_LEVELOptional | Log level, written to stderr: DEBUG, INFO, WARNING or ERROR. |
SEMANTIC_SCHOLAR_API_KEYOptional, secret | Optional. Raises the Semantic Scholar rate limit used by citation_snowball, the semantic_scholar source of unified_search and the DOI route of download_papers_pdf; without it requests are throttled and may get HTTP 429. |
OPENAI_API_KEYOptional, secret | Optional. Enables the LLM-powered tools (analyze_citations, literature_review, paper_screening, ...) with any OpenAI-compatible API. Needs the agentic extra. |
OPENAI_BASE_URLOptional | Optional. Base URL of an OpenAI-compatible API for the LLM tools. |
OPENAI_MODELOptional | Optional. Model for the LLM tools. |
UNPAYWALL_EMAILOptional | Optional. Your contact e-mail address, sent with each Unpaywall request (their terms ask for one). Used by the find_open_access and download_papers_pdf tools (without it download_papers_pdf skips the Unpaywall source); there is no default. |
PYEUROPEPMC_MCP_DOWNLOAD_DIROptional | Optional. Folder where the download_papers_pdf tool saves PDFs on the machine running the server. Default: ~/Downloads/pyeuropepmc. |
