Sec Insider MCP server

sec-insider

SEC Forms 3/4/5 — insider transactions, hosted so the question can be inverted.

Part of Pipeworx — an MCP gateway connecting AI agents to 1576+ live data sources.

Why this is hosted

Every insider API is company-first, ours included: you pass an issuer and get its Form 4s. "Which insiders bought the most last week, anywhere" has no filer to start from — the aggregation is across all issuers at once — so no upstream can answer it. A flat table makes it one indexed query.

Tools

open-market purchases across every issuer, by dollar value.

• insidertopbuyers({since?, until?, minvalueusd?, limit?}) — biggest

buying. Check this before trusting a ranking.

• insidertopsellers({…}) — the same for sales.
• insider_coverage() — which quarterly releases are loaded and what counts as

The transaction code is the whole meaning of a row

In the loaded window, 182,061 transactions break down as:

Only P is someone deciding to buy at market. A grant is compensation and an exercise is a conversion. A "biggest buyers" ranking that counts A or M puts insiders who bought nothing at the top, which is why this pack filters to P and says so in every response.

Two things about the data

Dates are filer-supplied and sometimes wrong. The loaded window holds 7 rows dated in the future — as far out as 2028 — and 2,902 dated before October 2025. The old ones are legitimate (Form 5 and amendments report prior periods); a future date is a typo. Ranking by recency without a guard puts a mistyped row at the top, so the newest-date probe is clamped to today.

The data lags by up to a quarter. SEC republishes these quarterly, so the most recent weeks are usually not in any release yet. The default window is anchored to the newest data actually loaded rather than to today — otherwise "the last 90 days" sits entirely past the edge of the data and returns nothing for a question that has an answer. A window with no rows says which releases are loaded rather than returning a bare empty list.

Loading

node scripts/ingest-sec-insider.mjs 2026q2 2026q1

The URL prefix moved. The newest quarter is published under /files/datastandardsinnovation/data/…; older ones remain under /files/structureddata/data/…. Both are live — 2026q2 answers only on the first, 2026q1 only on the second — so a loader that knows one prefix silently cannot see half the archive. Both are tried, newest layout first.

FOOTNOTES.tsv is the largest file in the zip (36.6 MB) and nothing here reads it; it is not extracted. Schema: supabase/migrations/072secinsider.sql.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "sec-insider": {
      "url": "https://gateway.pipeworx.io/sec-insider/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/sec-insider/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.
