TradeStar Insider tools (9, 1 write)

write = sends, deletes, buys or posts

activist_stakes_recentFree
Use when the user asks about activist investors, hedge-fund stakes, or recent 13D filings on a company. Returns activist Schedule 13D/13D-A filings on US-listed companies, newest first then by stated-intent strength; `ticker`, `min_percent` and `days` narrow. Each row carries its source filing_url and `item4_excerpt` (the activist's own Item 4 intent sentence, quoted from the filing as data, capped at its current length of 600 chars). Caveat: passive 13G is not covered; filings without a source link are dropped.
federal_awards_recentFree
Use when the user asks about recent federal contracts, government awards, or who won a U.S. federal contract. Returns newly signed federal awards, newest first; `min_amount` sets a USD floor, `days` a last-N-days window. Every award carries its source award_url. Caveat: awards without a source link are dropped and never returned.
fund_position_changesFree
Use when the user asks what a fund bought or sold, how a 13F filer changed its holdings, or which institutions opened/added/trimmed/exited a position. Returns quarter-over-quarter deltas, newest first; `filer`, `change_type`, `min_value_usd`, `days` narrow. Each row carries as_of_quarter_end, filed_date, lag_days, value_usd (whole dollars), cusip, issuer_name and its source filing_url; ticker is null (never guessed). Caveat: the delta is the product, not a trading edge — see the instructions and each response's `coverage` note for the universe and CIK scope.
insider_buysFree
Use when the user asks which insiders bought a stock, whether a ticker has insider buying, or for Form 4 buys in a date range. Pass `ticker`, `start`+`end` for an inclusive ISO range, or neither for today's buys (SEC code P); `days` narrows, `include_unlisted` adds non-listed issuers. Each row carries filing_url, `offering_context`, `transaction_date`, `acceptance_datetime`, `aff10b5One` (10b5-1 flag), `is_amendment`/`original_accession` (4/A linkage), and `partial_fields` (reason for any null). Caveat: only purchases that pass the signal filter are returned; code P is not proof of a buy.
insider_cluster_buysFree
Use when the user asks about cluster buying or several insiders buying the same company. Returns only clusters, two or more insiders buying one issuer in the window, newest first; days and ticker narrow. Each row carries filing_url, offering_context, uniform_price_cluster (true when 3+ insiders bought at one price on one day), `transaction_date`, `acceptance_datetime`, `aff10b5One` (10b5-1 flag), `is_amendment`/`original_accession` (4/A linkage), and `partial_fields` (reason for any null). Caveat: only purchases that pass the signal filter are returned; code P alone is not proof of a buy.
verify_13f_changeFree
Use when the user wants to verify or fact-check whether a fund (filer name/CIK) reported a CHANGE in a position in an issuer (issuer_name or cusip) in a quarter. Returns held (reported a change — opened/added/trimmed, with source filing + link), not_held (reported the position exited), not_found (no reported change — does NOT mean the fund didn't hold it), or out_of_coverage. Caveat: filing-verified; CANNOT confirm an unchanged holding (13F deltas only) — a 'held, unchanged' position produces no row.
verify_8k_eventFree
Use when the user wants to verify or fact-check that a company filed an 8-K carrying specific SEC item code(s) in a timeframe. Pass registrant (cik/company/accession), item code(s) and dates. Returns confirmed (with source filing + link), not_found, partial (itemised claimed-vs-filed), out_of_scope (claims about the filing's meaning aren't covered — it is never paraphrased), or out_of_coverage. Caveat: filing-verified — item codes are the SEC controlled vocabulary parsed from the filing, never inferred.
verify_activist_13dFree
Use when the user wants to verify or fact-check a claim about an activist stake or 13D filing (ticker/subject, filer, percent-of-class, stated intent, timeframe). Returns confirmed (with source filing + link), not_found, partial (itemised claimed-vs-filed), out_of_scope (passive 13G isn't covered), or out_of_coverage. Every response states the coverage window checked. Caveat: filing-verified — absence is reported as absence, never guessed.
verify_insider_purchasewrite actionFree
Use when the user wants to verify a claim that an insider bought a stock, or to pull the purchases in one filing by accession. Pass the claim (ticker/issuer, person, amount, timeframe), or `accession` alone for that filing's gated purchase records. Returns confirmed, not_found, partial, out_of_scope (sales/options/grants), or out_of_coverage. Each matched filing carries `transaction_date`, `acceptance_datetime`, `aff10b5One` (10b5-1 flag), `is_amendment`/`original_accession` (4/A linkage), and `partial_fields` (reason for any null). Caveat: filing-verified — absence is reported, not guessed.

What the publisher says

From the TradeStar Insider repository's README, as published. We do not edit it. Read it on GitHub

Insider Buy Signals

Verify any U.S. SEC filing claim, field-by-field, against the filing it came from. Every figure here — shares, price, dollar value, percent, stake size — traces to a parsed field in a real EDGAR filing and ships with a link to that filing on sec.gov. Records that can't be linked to a filing are dropped, never guessed: no scores, no unsourced numbers. We call this filing-verified. We also ran the obvious question — does insider buying predict returns? — as four sealed, pre-registered tests. I tried four times to prove otherwise, and four times the data said no; the full record is at https://www.tradestarinsider.com/what-we-tested. This repo is the MIT-licensed MCP server, client library, and worked examples for the TradeStar Insider API.

Free vs paid

The data is the same on every plan. Every row is filing-verified and links to its source on sec.gov. Plans differ only in reach and volume:

The free tier serves the last 30 days of filings. Older filings are not hidden: a request for an older date tells you the filing exists and is on the paid plan — it never claims that no filing exists. The verify_* tools check any filing across the full history for free. The paid plan is $29 a month on RapidAPI: 100,000 calls a month and full history since 2024, plus the key for the paid MCP endpoint from /v1/mcp-key.

(On RapidAPI the free Basic plan is 100 calls a day, or 3,000 calls a month where the console allows only a monthly quota.)

Run the MCP server locally

The server is published as insider-signals-mcp — a tiny stdio proxy to the remote endpoint. Run it with no install using uvx:

uvx insider-signals-mcp

To wire it into Claude Desktop, add this to claudedesktopconfig.json:

{
  "mcpServers": {
    "insider-signals": {
      "command": "uvx",
      "args": ["insider-signals-mcp"]
    }
  }
}

Or point any MCP client straight at the remote endpoint (no proxy needed): https://mcp.tradestarinsider.com/mcp (Streamable HTTP, no auth). The verify tools are the core: check an insider purchase, an activist 13D stake, an 8-K event, or a 13F holding against its source filing.

What the data is

Five filing-verified families from SEC EDGAR (plus federal contract awards from USAspending):

buying the same company inside a window of seven calendar days or fewer) and buys large relative to the insider's existing holdings.

Insider Form 4 purchases (SEC transaction code P) — cluster buys (two or more insiders

contract awards**.

Activist Schedule 13D stakes, 13F fund position changes, and **recent federal

Code P does not by itself prove an open-market buy. A purchase filed under P can be an IPO / offering / private-placement allocation, so every purchase record carries an offeringcontext flag (true = allocation, not open-market) and clusters carry a uniformpricecluster flag marking a single administered price. Option exercises, 10b5-1 planned sales, and sub-threshold noise (below $50,000) are dropped. Every field we return is parsed from a real filing and ships with its sec.gov link. Records that can't be linked to a filing are dropped, never guessed. No scores, no unsourced numbers.** We call this filing-verified.
