Available tools 4

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

activist

get_activist_stakes

Get Schedule 13D/13G beneficial-ownership filings (activist and 5%+ large-holder stakes) for one company - ticker is required. Returns one row per filing with filer names and the maximum reported percent of class; detailed item narrative text is not included. event_revision is always null for these forms (a fact of the form, not missing data). Data delayed 24 hours (known_at); recent filings only.

company

get_company_timeline

Get one merged, time-ordered feed of SEC insider activity for a company: Form 4 events, Schedule 13D/13G stake filings, and Form 144 sale notices, distinguished by the source_form field (form4 | sc13 | form144). The limit applies after merging, so companies with heavy Form 4 activity can crowd out 13D/G and 144 rows - use the dedicated tools for those. Unknown tickers fail with an error (404). Data delayed 24 hours (known_at); no price-derived fields.

insider

search_insider_events

Search interpreted insider-trading events from SEC Form 4 filings. Each event classifies raw filing rows into economic meaning (OPEN_MARKET_BUY vs EQUITY_AWARD vs TAX_WITHHOLDING_ONLY etc.), separating discretionary trades from compensation noise. Supports filtering by ticker, event type, minimum USD value, and time, with cursor pagination. Form 4 only - for 13D/G stakes or Form 144 sale notices use get_activist_stakes, get_sale_notices, or get_company_timeline. Data delayed 24 hours (known_at); history ~1 month; no price-derived fields.

sale

get_sale_notices

Get Form 144 notices of proposed insider sales for one company - ticker is required. shares_to_sell and aggregate_market_value are as-filed intentions announced before the sale, not executed trades - the matching Form 4 sale, if any, typically follows about a day later. event_revision is always null for this form. Data delayed 24 hours (known_at); recent filings only.

What can Cubesphere Insider do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_activist_stakes, get_company_timeline, get_sale_notices, search_insider_events. 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 →

Is Cubesphere 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 1833 ms. The bar chart above shows every period we have measured.

How do I connect Cubesphere Insider?

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 Cubesphere Insider need an API key?

No. Cubesphere Insider completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
