## MCP tools (3)

### `insider_top_buyers` (~718 tokens)

Stock purchases by a company's insiders and major holders, from SEC Form 4 — one buyer at one company, every buyer at one company, or the biggest buyers market-wide: "how much Occidental stock did Berkshire Hathaway buy in March", "insider buying at Pfizer this quarter", "which insiders bought the most stock recently", "largest insider purchase last month". Pass issuer (ticker or company name) and owner (a person or a firm, e.g. "Berkshire") to narrow it, since/until for the period, and group_by "owner" for one buyer's total across several filings. Officers, directors and 10% owners — including large investors and funds holding over 10% of a company — file a Form 4 within two business days of every trade, so this gives the exact trade dates, shares, price per share and dollar value inside any month or week. Returns the insider name and role, the issuer and ticker, shares, price and value. Counts only transaction code P, a purchase at market; option exercises, grants and tax withholding are excluded because none of them is a decision to buy. Ranks over every row in the window — never a capped slice — and reports rows_considered so a cut is never silent. A price the filer states in another currency (e.g. Brazilian reais, in a footnote) is left out and counted in non_usd_rows_excluded, never ranked as dollars. A price that looks like a filer data-entry error is left out unless include_suspect is set, and a report filed as several parts counts as one filing. Sourced from SEC Forms 3/4/5.

Input parameters:

- `exclude_funds` (boolean): Drop issuers that are funds reporting unitholders, not operating companies with real insiders (e.g. a BDC or interval fund). Best-effort name/security-type heuristic. Default false.
- `group_by` (string): How to roll transactions up before ranking. "filing" (default): sum every row on the same Form 4 into one total — a filing often reports one decision as several price-band lines, and a price-band row…
- `include_suspect` (boolean): Include transactions whose price looks like a filer data-entry error (see the caveat). Default false — suspect rows are excluded from rankings.
- `issuer` (string): Limit to one issuer — ticker (e.g. "LEN") or SEC CIK. Substring match on issuer name also works.
- `limit` (number): How many to return (default 20, max 100).
- `min_value_usd` (number): Ignore transactions below this dollar value.
- `owner` (string): Limit to one insider — name substring (e.g. "Berkshire") or SEC CIK.
- `since` (string): Earliest transaction date, ISO (YYYY-MM-DD). Defaults to the last 90 days of the loaded window.
- `until` (string): Latest transaction date, ISO (YYYY-MM-DD).

### `insider_top_sellers` (~686 tokens)

Stock sales by a company's insiders and major holders, from SEC Form 4 — one seller at one company, every seller at one company, or the biggest sellers market-wide: "how many Amazon shares did Jeff Bezos sell in July", "insider selling at Apple this year", "which insiders sold the most stock recently", "largest insider sale last month". Pass issuer (ticker or company name) and owner (a person or a firm) to narrow it, since/until for the period, and group_by "owner" for one seller's total across several filings. Officers, directors and 10% owners file a Form 4 within two business days of every trade, so this gives the exact trade dates, shares, price per share and dollar value inside any month or week. Returns insider name and role, issuer and ticker, shares, price and dollar value. Counts only transaction code S, a sale at market; shares withheld for tax (F) are excluded, since those are a payroll mechanism rather than a decision to sell. Ranks over every row in the window — never a capped slice — and reports rows_considered so a cut is never silent. A price the filer states in another currency (e.g. Brazilian reais, in a footnote) is left out and counted in non_usd_rows_excluded, never ranked as dollars. A price that looks like a filer data-entry error is left out unless include_suspect is set, and a report filed as several parts counts as one filing. Sourced from SEC Forms 3/4/5.

Input parameters:

- `exclude_funds` (boolean): Drop issuers that are funds reporting unitholders, not operating companies with real insiders (e.g. a BDC or interval fund). Best-effort name/security-type heuristic. Default false.
- `group_by` (string): How to roll transactions up before ranking. "filing" (default): sum every row on the same Form 4 into one total — a filing often reports one decision as several price-band lines, and a price-band row…
- `include_suspect` (boolean): Include transactions whose price looks like a filer data-entry error (see the caveat). Default false — suspect rows are excluded from rankings.
- `issuer` (string): Limit to one issuer — ticker (e.g. "LEN") or SEC CIK. Substring match on issuer name also works.
- `limit` (number): How many to return (default 20, max 100).
- `min_value_usd` (number): Ignore transactions below this dollar value.
- `owner` (string): Limit to one insider — name substring (e.g. "Berkshire") or SEC CIK.
- `since` (string): Earliest transaction date, ISO (YYYY-MM-DD).
- `until` (string): Latest transaction date, ISO (YYYY-MM-DD).

### `insider_coverage` (~56 tokens)

Which SEC insider data is currently available: which quarterly releases are covered, how many filings, owners and transactions, and the date range of the transactions themselves. Call this to check how current the insider data is before relying on a ranking.

## Common questions

### What is the Sec Insider MCP server?

Sec Insider is an MCP server listed in the public MCP registry as io.github.pipeworx-io/sec-insider. SEC Forms 3/4/5, insider transactions, indexed so the question can be inverted. This page covers its npm package (@pipeworx/mcp-sec-insider).

### Is the Sec Insider MCP server safe to use?

Sec Insider scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Sec Insider MCP server expose?

Sec Insider exposes 3 tools: insider_top_buyers, insider_top_sellers, insider_coverage. Their descriptions and schemas cost roughly 1,460 tokens of context every time the server is loaded.

### Is the Sec Insider MCP server still maintained?

Sec Insider is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sec Insider MCP server under?

Sec Insider declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Sec Insider MCP server?

VerifyMCP ran 16 checks on Sec Insider, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
