Search academic papers by keyword. Returns structured results: title, year, venue, authors, DOI, abstract, citation count, and an open-access PDF link when available.

source:

• "auto" (default): Semantic Scholar first, automatic OpenAlex fallback.

• "semanticscholar" / "openalex": force one engine.

• "arxiv": search the arXiv preprint API directly — best for finding specific recent papers by exact name. Supports arXiv field syntax in query, e.g. 'ti:"carbon intensity" AND abs:forecast'.

• "dblp": search DBLP publications (supports venue).

Optionally filter by venue (e.g. "e-Energy"). Venue-scoped queries are routed through DBLP automatically, because OpenAlex has no usable venue filter. All results are cached on disk, so repeat searches are instant even if an API rate-limits.

Get full metadata for a paper. Pass a DOI (e.g. "10.1109/tpwrs.2018.2823641"), an arXiv ID (e.g. "2407.19074", "arXiv:2407.19074", or an arxiv.org/abs/... URL), or an OpenAlex ID (W...). Semantic Scholar first, OpenAlex/Crossref fallback: title, authors, venue, year, abstract, TLDR, citation count, DOI, and open-access PDF.

Follow a paper's citation graph. paper_id is a DOI, an OpenAlex ID (W...), or a Semantic Scholar paper ID. direction: "citing" (papers that cite this paper, forward search) or "referenced" (papers this paper cites, backward search). Returns structured results plus the data source used. Results are cached.

List papers published in a venue's proceedings (via DBLP) — for surveying what a conference like ACM e-Energy actually accepts. Returns title, year, authors, DOI.

venue: a venue name (e.g. "e-Energy") or a DBLP stream key (e.g. "conf/eenergy"). year: optional single year to filter proceedings (e.g. 2024). query: optional keyword to only return papers matching a topic (e.g. "carbon"). Results are cached, so re-surveys are instant.

Generate a BibTeX citation entry for a paper by DOI via Crossref (falls back to local generation from OpenAlex metadata). Result is cached.

Read the full text of a paper. Pass a DOI, an arXiv ID (e.g. "2407.19074"), or a direct PDF URL. Resolves the open-access PDF automatically, downloads it (cached locally under ~/.cache/research-mcp/pdf/ by default), extracts the text with PyMuPDF, and returns up to max_chars characters.

Use paper_details or search_papers to find a paper's open_access_pdf first; pass that URL directly if DOI resolution finds no open-access copy.
