What it does

Give it a company domain and a definition of your ICP, and it scores the company on weighted signals, returning a 0 to 100 score, an A to D tier, and a per-signal breakdown. Define your ICP three ways: a prebuilt template, a JSON scoring config, or a plain-English description (which uses your own LLM key). Turn on fetch_signals and the actor will gather hiring and tech-stack signals for you before scoring. One flat row, ready for Clay, a CRM, or an AI agent workflow. All of the scoring 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:

{
  "mcpServers": {
    "mamba-icp-scorer": {
      "command": "npx",
      "args": ["-y", "@mambalabsdev/mcp-icp-fit-scorer"],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

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

Prerequisites

• Node.js 18 or newer
• An Apify account with an API token

Example prompts

• "Score clay.com against the b2b_saas template and fetch its signals."
• "How well does stripe.com fit an ICP of mid-market fintech companies? Explain the score."
• "Score figma.com with my scoring config and include the per-signal breakdown."
• "Rate openai.com against this ICP description: enterprise AI teams hiring for go-to-market."

Inputs

Every input the tool accepts, generated from the server's own tool list.

score_icp_fit

list_icp_templates

No inputs. Returns the six prebuilt template names score_icp_fit accepts, with the actor's note on how they differ. It answers locally: no Apify run, no token, and no charge.

Define your ICP with exactly one of template, scoring_config, or icp_description.

This server exposes the single-company scoring path. The actor also supports batch inputs (a dataset or CSV of companies) and a results webhook. For those, run the actor directly on Apify.

Output

The tool returns the actor's flat JSON row for the scored company, including icp_score (0 to 100), icp_tier (A to D), the per-signal breakdown, and an optional explanation. See the Apify Store page for the full output schema.

Example output

{
  "company_domain": "ramp.com",
  "icp_score": 87,
  "icp_tier": "A",
  "lead_tag": "priority",
  "score_hiring": 25,
  "score_tech_stack": 22,
  "score_headcount": 20,
  "score_funding": 20,
  "score_industry": 0,
  "run_date": "2026-05-28"
}

Features

• User-defined JSON scoring config with custom weights
• Returns icp_score (0 to 100), icp_tier (A to D), and lead_tag
• Per-signal point breakdown: hiring, tech stack, headcount, funding, industry
• Replaces 6+ manual formula columns in Clay

How each call runs

Each call starts the actor run, polls it until it finishes, then reads the dataset. The run is allowed 1,800 seconds. If the run is still going when this call stops waiting, the call returns the run id and a console link instead of a timeout, so the result is never lost.

This server is a thin client and holds no scoring logic. For the complete input and output reference, pricing, and run history, see the Apify Store page:
