    How to connect

    How to connect Insider Buy Signals to Claude

    The server address to paste into Claude settings:

    https://mcp.tradestarinsider.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    The server address to paste into ChatGPT settings:

    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).

    insider_signals_todayRule-2 insider-buy signals filed today (SEC code P open-market purchases), ranked cluster-first. Each record carries its source filing_url.
    insider_signals_by_tickerAll Rule-2 insider-buy signals for one ticker (case-insensitive). Each record carries its source filing_url.
    insider_signals_by_date_rangeRule-2 insider-buy signals filed within an inclusive ISO date range. Each record carries its source filing_url.
    insider_cluster_buysRule-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_lookupThe single Rule-2 record for one SEC filing accession, with its filing_url. Returns an error if no gated filing matches the accession.
    federal_awards_recentRecently 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.
    activist_stakes_recentRecent 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.
    verify_insider_purchaseCheck 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.
