What it does

Give company legal names or SEC CIKs. For each company the actor finds its SEC entity, lists every Form D (private placement) and Form C (crowdfunding) offering it filed, and reads the latest document of each. You get one company row with totals and dates, and one row per offering with amounts offered and sold, the first sale date, security types, investor count, executives, the crowdfunding platform for Form C, and a link to the filing.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

{
  "mcpServers": {
    "mamba-private-company-funding-history": {
      "command": "npx",
      "args": [
        "-y",
        "@mambalabsdev/mcp-private-company-funding-history"
      ],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Restart the client. The get_company_funding_history tool appears.

Prerequisites

Node.js 18 or newer.
An Apify API token from console.apify.com/account/integrations, set as APIFY_TOKEN. The server lists its tool without a token; a call needs one.
