Why AlphaSMO

• 📊 13F institutional holdings — every hedge fund and asset manager's quarterly SEC filings: AUM, positions, and behavioral "personality scores" (concentration, turnover, sector conviction). Read our guide on What Is a 13F Filing? and How to Read Institutional Holdings Changes.
• 🕵️ Insider trading (Form 4 & 144) — officer/director/10%-owner buys and sells, with a confidence score per ticker. Learn more in What Is a Form 4 Filing? and What Is a Form 144 Filing?.
• 🚀 Smart money convergence — the flagship signal: tickers where 13F institutions and company insiders are both buying right now.
• 🤖 Built for AI agents — an MCP server out of the box, so Claude, ChatGPT, Cursor, or any MCP client can pull real financial data mid-conversation.
• 🆓 Free anonymous tier — no signup required to try it; get a free API key any time to raise your rate limit.

Use cases

"What is smart money buying right now?"        → alphasmo convergence
"What does Berkshire Hathaway hold?"            → alphasmo institutions holdings berkshire-hathaway-inc
"Are insiders buying or selling NVDA?"          → alphasmo insider summary NVDA
"Which stocks are institutions dumping?"        → alphasmo stocks flows --direction sell

Wire the MCP server into Claude Desktop, Claude Code, Cursor, or any MCP client (see below) and ask these in plain English — no code required.

CLI

npx alphasmo institutions search "Berkshire"
npx alphasmo stocks get AAPL
npx alphasmo convergence -l 5

No install step required — npx fetches and runs it. Or install globally:

npm install -g alphasmo
alphasmo --help

Commands

Command	What it returns
alphasmo institutions search <query> [-l|--limit]	Search 13F institutions by name
alphasmo institutions list [-l|--limit] [-o|--offset]	Paginate the full institution universe (no query)
alphasmo institutions get <slug>	Full institution detail, sector weights
alphasmo institutions holdings <slug>	Latest 13F holdings for one institution
alphasmo stocks get <identifier>	Full stock detail — holder count, flows, top holders (identifier = ticker or CUSIP)
alphasmo stocks flows [-d|--direction buy|sell] [-l|--limit]	Stocks ranked by net institutional buy/sell flow
alphasmo insider trades <ticker>	Recent individual Form 4 insider trades for one ticker
alphasmo insider summary <ticker>	Insider confidence scores (30d/90d) for one ticker
alphasmo convergence [-l|--limit] [--min-confidence] [--days]	Tickers where 13F institutions and insiders are both buying — the flagship signal
alphasmo mcp	Start the MCP server over stdio

Global flags on every command: --api-key <key> (env ALPHASMO_API_KEY), --base-url <url> (env ALPHASMO_BASE_URL), -f/--format json|compact|table|csv, --json (shorthand for --format json), --csv (shorthand for --format csv).

Output format auto-detects your context — no flag needed in the common case:

• Typed directly in a terminal → a readable table, with numbers comma-formatted (263,095,703,570).
• Piped, redirected, or spawned by a script/AI agent (stdout isn't a TTY) → JSON, safe to pipe into jq or feed to an agent.
• --format/--json/--csv always override the auto-detection either way.

alphasmo stocks flows --csv > flows.csv
alphasmo insider trades AAPL --csv | column -s, -t

Errors go to stderr with a distinct exit code (2 not found, 3 auth, 4 rate limit, 5 unexpected response shape, 1 other), so scripts can branch without string-matching.

Get an API key

Anonymous requests are rate-limited by IP. Sign up and mint a free key at alphasmo.com/developer, then:

alphasmo convergence --api-key ask_live_...
# or
export ALPHASMO_API_KEY=ask_live_...

MCP server

Option 1: claude mcp add (recommended)

If you're using Claude Code, register the server with one command:

claude mcp add alphasmo -- npx -y alphasmo@latest mcp

Add -e ALPHASMO_API_KEY=ask_live_... before the -- to raise your rate limit. Run claude mcp list to confirm it's connected.

Option 2: manual MCP client config

For Claude Desktop, Cursor, or any other MCP client, add this to your config file directly:

{
  "mcpServers": {
    "alphasmo": {
      "command": "npx",
      "args": ["alphasmo", "mcp"],
      "env": { "ALPHASMO_API_KEY": "optional-your-key-here" }
    }
  }
}

Both options work anonymously out of the box, at lower rate limits than with a key. Tools exposed: search_institutions, get_institution_profile, get_institution_holdings, get_stock_overview, get_stock_flows, get_insider_activity, get_smart_money_convergence.

Full endpoint reference: alphasmo.com/developer/docs.

Programmatic use

import { AlphasmoClient } from "alphasmo";

const client = new AlphasmoClient(); // no apiKey needed to try it
console.log(await client.getSmartMoneyConvergence({ limit: 5 }));

npm install alphasmo

A Python client + MCP server is also available — see alphasmo.com/developer for setup.
