Get PDF document information including metadata, page count, and table of contents. Always call this first to understand the document structure before reading content. toc is inlined when toc_entry_count <= 50 (independent of detail); for larger TOCs call pdf_get_toc.

Read text, images, and tables from specific PDF pages. Supports page ranges like '1-5,10' and OCR for scanned pages.

Read the full document text up to max_pages and up to the configured response byte cap, starting at start_page. When a previous call returned next_page=N, pass start_page=N to this same tool to resume on a clean page boundary.

Search the PDF using keyword, semantic, or auto (hybrid RRF) modes, at page or section granularity. Returns ranked matches. Excerpts default to structural text blocks (excerpt_style='paragraph'); pass excerpt_style='snippet' for fixed-width windows. Section-mode matches_omitted counts byte-cap drops only — raise max_results to surface more candidates.

Cache diagnostics: file counts, sizes, and the local cache directories pdf-mcp is using. Intended for debugging the local install — the directory paths in the response are local filesystem paths (single-user STDIO deployment) and should not be forwarded to remote agents.

Report which optional features are installed and what configuration is active on this pdf-mcp server. Call this first when about to use semantic search, OCR, or column-aware extraction — if the feature isn't available, downstream calls will either fall back silently (column-aware → positional sort) or fail (semantic mode → error). Returns version, per-feature availability with descriptions, search mode list, and active config values. Cheap to call (no I/O beyond reading process state). Results are stable for the server's lifetime.
