mambalabsdev/mcp-gtm-tech-stack-signal-scraper

An MCP server that detects which go-to-market tools a company runs, straight from its public website. It wraps the Mamba Labs Tech Stack Signal Detector actor on Apify and returns a Clay-ready flat JSON row to any MCP client.

What it does
Give it a company domain and it inspects the public-facing scripts and pages to detect the CRM, sequencer, and marketing automation tools in use. You get back per-tool boolean flags (HubSpot, Salesforce, Apollo, Gong, Intercom, Marketo), counts, and a composite tech stack signal, ready to drop into Clay, a CRM, or an AI agent workflow. All of the detection runs on Apify. This package is a thin client that calls the actor and hands back the result.
Quick start
You need Node.js 18 or newer and an Apify account with an API token.
Add this to your Claude Desktop config:
Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The detect_gtm_tech_stack tool will be available.
Prerequisites
- Node.js 18 or newer
- An Apify account with an API token
Example prompts
- "What GTM tools does stripe.com run? Check their tech stack."
- "Does openai.com use HubSpot or Salesforce? Detect their CRM."
- "Pull the marketing automation and sequencer signals for figma.com."
- "Detect the GTM tech stack for datadoghq.com and list every tool found."
Inputs
Every input the tool accepts, generated from the server's own tool list.
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| domain | string | no | Bare company domain without https:// and without a trailing slash. Example: stripe.com. Supply this, company_domain or url. |
| company_domain | string | no | Deprecated alias for domain, accepted by the actor for older callers. Prefer domain. |
| url | string | no | Deprecated alias for domain, accepted by the actor as a full company website URL. Prefer domain. |
| domains | array of string | no | A list of bare company domains to check in one run, one row per domain. The actor processes them in batches inside a single run, so a list costs one run start instead of one per domain. Use this or domain. |
| crawl_additional_pages | boolean | no | If true, crawls up to 2 additional pages per domain (pricing, product) to improve detection coverage. Slightly increases run time. Defaults to true when omitted. |
| technologies | array of hubspot, salesforce, marketo, pardot, intercom, drift, apollo, outreach, gong, zoominfo | no | Report only these tools instead of every detectable one, which is how you answer "is this company using X". Only the ten tools with a client side fingerprint are selectable; Clay, Salesloft, Instantly and Lemlist leave no trace on a website and cannot be detected from one. Detection is unchanged either way, so a filtered call costs the same and reuses the same cache. Omit for every tool. |
| skipCache | boolean | no | By default a clean detection is cached for 7 days and reused on repeat lookups, skipping the browser launch. Set true to force a fresh detection and ignore any cached result. |
