Insider Buy Signals MCP server

• activist_stakes_recentFree

  Recent activist Schedule 13D / 13D-A filings on US-listed companies, newest first then by stated-intent strength (control/take-private > board/proxy > strategic/value, or none stated). Optional min_percent (percent-of-class floor), ticker, and limit. Every stake carries its source filing_url; filings without a source link are dropped.

• federal_awards_recentFree

  Recently signed U.S. federal new awards from USAspending.gov, newest first. Optional min_amount (USD floor) and limit. Every award carries its source award_url; awards without a source link are dropped and never returned.

• fund_position_changesFree

  What large institutional filers CHANGED quarter-over-quarter in their SEC 13F-HR holdings (opened / added / trimmed / exited a position) — the delta is the product; the raw snapshot is only the input. Every row carries as_of_quarter_end, filed_date and lag_days (values are up to ~45 days stale), value_usd in whole dollars, cusip + issuer_name, and its source filing_url. ticker is null (no authoritative free CUSIP->ticker source; never guessed). A missing prior quarter is the explicit state 'first_filing_on_record', not 'everything new'. Covers LONG US 13(f)-listed positions only — no shorts, non-US, or options. This is a convenience/completeness view of public data, NOT a trading edge. Optional filer, change_type, min_value_usd, limit.

• insider_cluster_buysFree

  Rule-2 cluster buys only (>=2 insiders buying the same issuer in-window) — the highest-signal subset. Each record carries its source filing_url.

• insider_filing_lookupFree

  The single Rule-2 record for one SEC filing accession, with its filing_url. Returns an error if no gated filing matches the accession.

• insider_signals_by_date_rangeFree

  Rule-2 insider-buy signals filed within an inclusive ISO date range. Each record carries its source filing_url.

• insider_signals_by_tickerFree

  All Rule-2 insider-buy signals for one ticker (case-insensitive). Each record carries its source filing_url.

• insider_signals_todayFree

  Rule-2 insider-buy signals filed today (SEC code P open-market purchases), ranked cluster-first. Each record carries its source filing_url.

• verify_8k_eventFree

  Check a claim that a registrant (cik/company/accession) filed an 8-K carrying specific SEC item code(s) in a timeframe, against the filed record. Returns status=confirmed with the source filing(s) + link; not_found; partial (same registrant/filing but the claimed item(s) aren't carried, or the date differs — itemised claimed-vs-filed); out_of_scope (claims about the body's meaning/materiality aren't covered — the filing is never paraphrased); or out_of_coverage. Every response states the coverage window checked. Rule-2: item codes are the SEC controlled vocabulary parsed from the filing — never inferred from prose.

• verify_activist_13dFree

  Check a claim about an activist stake (ticker/subject, filer, percent-of-class, stated intent, timeframe) against the filed Schedule 13D/13D-A record. Returns status=confirmed with the source filing(s) + link; not_found; partial (same filer/subject but percent/intent/date differs, itemised claimed-vs-filed); out_of_scope (passive 13G isn't covered); or out_of_coverage (outside the collected window). Every response states the coverage window checked. Rule-2: no estimates — absence is reported as absence, never guessed.

• verify_insider_purchasewrite actionFree

  Check a claim about an insider open-market buy (ticker/issuer, person, amount, timeframe) against the filed record. Returns status=confirmed with the source filing(s) + link; not_found; partial (same insider/company but value/date differs, itemised claimed-vs-filed); out_of_scope (sales/options/grants aren't covered); or out_of_coverage (outside the collected window). Every response states the coverage window checked. Rule-2: no estimates, no unlabelled partial matches — absence is reported as absence, never guessed.
