First indexed and scored.

## MCP tools (2)

### `discover_sec_companies` (~326 tokens)

Discover SEC companies

Find public companies and evidence in indexed SEC 10-K and 10-Q filings. Use for industry-wide discovery, named-company research or peer comparisons.

Returns ranked research leads with 1-3 passage previews per company, filing metadata and source links, not a synthesized answer. Inspect relevant originals with get_sec_passage before making factual or numerical claims; previews can omit key evidence and qualifications.

When available, discovery includes consolidated financial context. Check each figure's own period, source and availability. Numeric conditions may be checked for supported measures, periods and scope; unknown or absent verdicts mean unverified. Returned companies are not guaranteed numerical matches. Figures do not establish causation.

Coverage is bounded: max_companies is a ceiling; missing companies and empty results do not prove absence of evidence. tickers OR sic_codes restrict the universe. filed_since filters filing dates, not report periods. Exact period references may restrict filings; inspect reporting_period notices for fallback.

Each successful request, including a valid empty result, consumes one research allowance unit. Run discoveries sequentially per account; concurrent requests may return account_busy. Do not automatically retry failed or uncertain requests.

Input parameters:

- `filed_since`: Inclusive SEC filing date. No hidden date default.
- `max_companies` (integer)
- `question` (string, required): Natural-language SEC research question. Substantive alternatives and relationships matter.
- `sic_codes` (array): Explicit four-digit industry codes, retaining leading zeroes. Alternative to tickers.
- `tickers` (array): Explicit company universe. Alternative to sic_codes; never relaxed.

### `get_sec_passage` (~89 tokens)

Read discovered SEC passage

Read the full original SEC passage and available adjacent same-section context using a passage_id from discovery. Verify facts, amounts, dates, actual versus hypothetical disclosures, management explanations and qualifications before answering or citing. Context may omit referenced tables or other sections; do not infer missing facts or causation. No new discovery or model call; no research allowance unit consumed.

Input parameters:

- `passage_id` (string, required)
