Overview

AI-generated overview

Remote MCP server that turns SEC insider filings into clean events: Form 4 trades, Form 144 sale notices and 13D/G stakes, searchable by ticker.

What you can do
  • Search interpreted insider-trading events from SEC Form 4 filings, filtered by ticker, event type and minimum value, with compensation noise separated from discretionary trades
  • Get a merged, time-ordered timeline of a company's insider activity across Form 4, Schedule 13D/13G and Form 144 filings
  • Retrieve Schedule 13D/13G beneficial-ownership filings for a company, with filer names and maximum reported percent of class
  • Retrieve Form 144 notices of proposed insider sales, with as-filed share counts and aggregate market value
When to use it
Useful when you want an assistant to look up who is buying or selling a company's stock, track activist or 5%+ holder stakes, or assemble a chronological view of insider activity from SEC filings without parsing raw forms yourself.
Requirements
A remote streamable HTTP endpoint; no package, environment variables or headers are declared. Network access to the endpoint is needed.
Before you install
Form 144 figures are announced intentions, not executed trades, and 13D/G results omit detailed item narratives; event_revision is always null for those filings. The server is read-only lookups, but results are filing data and should not be treated as investment advice.

Installation

In SourceWeft

  1. Open Cubesphere Insider in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/xyz.cubesphere%2Finsider/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

Parameterslimitsincecursortickermin_valueevent_type

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.

Parameterslimittickerrequired

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.

Parameterslimittickerrequired

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.
