The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_financials ~152
Deterministic financial report from statements YOU extracted from the get_filing PDF(s): normalize → ratios → red flags → trends (with 2+ years). Record figures verbatim as printed and set each statement's unit field ("czk" | "thousands_czk" | "millions_czk") to the scale the statement declares (usually 'v celých tisících Kč' → thousands_czk); the server converts everything to thousands of CZK, so multi-year trends stay comparable. Pass the ico to enrich red flags with insolvency and unreliable-VAT-payer checks.

estimate_valuation ~234
Indicative, deterministic enterprise value from statements YOU extracted. One primary method: EV/EBITDA (EBITDA = operating profit + depreciation), where the multiple is a Damodaran Europe sector figure adjusted for a Czech private company (country, liquidity, profitability, growth and cash- conversion factors, clamped to 3-18x). Companies with non-positive EBITDA fall back to net assets. Returns a point estimate with a confidence band, plus every factor applied. Classify the industry yourself from what the filing says the company does — you read it, and that beats a registry code. Pass `industry_key`. Failing that, pass `ico` to map CZ-NACE to a sector at lower confidence. Set each statement's unit field ("czk" | "thousands_czk" | "millions_czk") and pass figures verbatim as printed; results are in thousands of CZK. Book values are not market values. NOT investment advice.

get_filing ~247
Download a financial statement PDF from Sbírka listin (latest, or by year / filing id from list_filings). Returns filing metadata with a local file_path and page_count, and — depending on `embed` — the PDF bytes. embed: - "auto" (default): embed only if the PDF fits the server's size cap. - "never": metadata + file_path only. FILESYSTEM-CAPABLE HOSTS (Claude Code, Codex, Desktop with fs access) SHOULD pass embed="never" and read the PDF from file_path — filed statements are routinely 20-25 MB and the path is strictly better than putting ~33 MB of base64 in context. - "always": embed regardless (still hard-capped; an honest message is returned instead of silently dropping an over-cap PDF). Read the PDF yourself (or call read_filing_text for a page range), then pass extracted figures to analyze_financials — no server-side API key needed.

read_filing_page_images ~155
Rasterize statement PDF pages to PNG images — keyless, no LLM, no OCR. For SCANNED filings with no text layer (read_filing_text reports has_text=false) on hosts WITHOUT filesystem access: this delivers legible page images the host model can read directly. Page grammar: "3", "1-5", "1-3,5" (default "1-5"). At most 5 pages per call (images are token-heavy); request later ranges for the rest. Returns one metadata text block, then one PNG image per rendered page.

read_filing_text ~137
Extract the embedded text layer of a statement PDF for a page range — keyless, no LLM, no OCR. Page grammar: "3", "1-5", "1-3,7" (default "1-10"). At most 20 pages per call. Czech filings are often scanned images with no text layer; pages without text are reported honestly (has_text=false) with a note pointing to read_filing_page_images or filesystem reading — never a silent empty string.
