Insider Buy Signals missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 8

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

insider

insider_cluster_buys

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_lookup

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_range

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

insider_signals_by_ticker

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

insider_signals_today

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

activist

activist_stakes_recent

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

federal_awards_recent

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.

verify

verify_insider_purchase

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.

Is Insider Buy Signals 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 226 ms. The bar chart above shows every period we have measured.

How do I connect Insider Buy Signals?

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

Does Insider Buy Signals need an API key?

No. Insider Buy Signals completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Insider Buy Signals?

It answers our handshake in 226 ms on average, which is faster than 61% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
