An MCP server that returns a company funding record from SEC Form D, Companies House and press, each labeled with the source it came from. It wraps the Mamba Labs Funding Record from SEC and Companies House actor on Apify and returns a Clay-ready flat JSON row to any MCP client.

What it does

Give it a company name and domain and it reads primary sources and returns a funding record: SEC EDGAR Form D amounts, UK Companies House registration details, and press coverage of funding rounds. One flat row per company.

Every number travels with a source_of_record saying whether it came from a legal filing or from a press release, because those are not the same kind of fact and merging them is the defect this tool exists to prevent. Only an exact entity match, after corporate suffixes are stripped, populates an amount. A near match such as a differently named subsidiary goes to separate related_entity columns as a named lead and can never be summed into a total. This is not Crunchbase and not a resold database, so it returns less than a database would and what it returns has a filing behind it.

All of the lookup runs on Apify. This package is a thin client that calls the actor and hands back the result unchanged.

Quick start

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

Add this to your Claude Desktop config:

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

Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The get_company_funding_record tool will be available.

Prerequisites

• Node.js 18 or newer
• An Apify account with an API token
• Optional: your own Companies House REST API key, free at developer.company-information.service.gov.uk, if you want the UK columns populated

Example prompts

• "Get the funding record for Anthropic at anthropic.com."
• "Has Notion filed a Form D in the last 24 months? Regulatory sources only."
• "Look up funding for this UK company and flag anything above 10 million dollars."
• "Show me press reported funding for figma.com and keep it separate from any filing."

Inputs

• company_domain (optional): bare company domain, for example notion.com. Used to derive a company name when none is given, and carried on the row as the join key.
• company_name (optional but strongly recommended): every source here is searched by name rather than by domain, and the name is what the entity gate compares a filing against. A wrong or missing name is the largest source of wrong rows.
• sources (optional): which sources to query. One of all, regulatory, sec_only, uk_only or press_only. Regulatory sources are filings and are authoritative; press is the most recent and least verified. Choose regulatory when a number has to be defensible and all when recency matters more.
• lookbackMonths (optional): how far back to consider a filing. One of 12, 24, 36, 60 or 120, with 36 months the default. A Form D from six years ago is a real filing and usually not a current signal, and this is where you say which you mean.
• minAmountUsd (optional): one of none, 1000000, 5000000, 10000000 or 50000000. It sets amount_meets_threshold on the row so you can filter to material raises without writing the comparison yourself. It never drops a row and never changes the amount returned.
• companiesHouseApiKey (optional): your own Companies House REST API key, free at developer.company-information.service.gov.uk. Without one the UK columns report skipped rather than guessing, and the SEC and press sources still run.
• skipCache (optional): when false (the default) a successful lookup is cached for seven days and reused. Set true to force a fresh fetch.
• max_charge_usd (optional): a cost cap in USD for this run. The actor stops before an item that could take its charges past this amount. Omit it to rely on the maximum cost per run set in Apify.

Output

The tool returns the actor's flat JSON row for the company, with 32 snake_case fields and no nested objects. source_of_record says where a number came from, form_d_entity_match and uk_entity_match record how strict the entity match was, and filings_rejected counts what the entity gate turned away. See the Apify Store page for the full output schema.

Mamba Labs GTM Suite

This server is one of the Mamba Labs GTM Suite MCP servers. Every actor in the suite takes a domain or a company and returns one flat row, so they stack in the same Clay table without reshaping anything. The actor behind this server is the Funding Record from SEC and Companies House, immutable Apify actor ID OFS4Mt1gyYNtGfUbE.
