Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verify

verify_13f_change

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_event

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_13d

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_purchase

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.

insider

insider_amendments_recent

Use when the user asks which insider filings were amended, corrected, or restated, or wants recent Form 4/A amendments. Returns 4/A amendments, newest-filed first; `ticker`, `issuer_name`, `person`, `start`/`end`, `days` narrow. Each row carries the amendment_accession, filed_date, issuer/insider, source filing_url, the original_accession it amends (when collected), and `changed_fields` (before/after). Caveat: when the original is not collected the amendment is still listed with original_in_corpus=false and before/after null (never guessed); linkage is by issuer/owner/period.

insider_buys

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_buys

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.

activist

activist_stakes_recent

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

federal_awards_recent

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

fund_position_changes

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.

TradeStar Insider — questions

Answers built from our own checks of this server.

What can TradeStar Insider do?

It exposes 10 tools, read directly from the server on our last check. Among them: activist_stakes_recent, federal_awards_recent, fund_position_changes, insider_amendments_recent, insider_buys, insider_cluster_buys and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is TradeStar Insider mostly used for?

Its tools cluster around verify and insider. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is TradeStar Insider working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 195 ms. The bar chart above shows every period we have measured.

Did TradeStar Insider ever remove tools?

Yes. verify_13f_holding, insider_filing_lookup, insider_signals, insider_signals_by_date_range and 2 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect TradeStar Insider?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does TradeStar Insider need an API key?

No. TradeStar Insider completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is TradeStar Insider?

It answers our handshake in 195 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use TradeStar Insider?

The npm package insider-signals-mcp was installed 80 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is TradeStar Insider open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.tradestarinsider.com, which runs on its operator's own terms.
