Who is TAM SAM SOM Calculator not ideal for?

Anyone who cannot give the required inputs (Total potential companies, Average contract value); the answer is built only from them.
Teams looking for a list of companies to target: the tools describe and score profiles from your data but find no companies.
Market sizing without your own numbers: TAM, SAM and SOM come only from the figures you enter.

How do I use TAM SAM SOM Calculator from Claude?

Connect ICP Intelligence once (see Connect), then ask in plain words. A prompt built from the tested example:

Use ICP Intelligence's TAM SAM SOM Calculator tool. total potential companies: 12000; average contract value: 8000; icp percentage: 25; year 1 market share target: 1; segment name: US clinic groups.

MCP tool name: tam_sam_som_calculator. REST: POST https://icp-intelligence.gtmhelix.com/api/tools/tam_sam_som_calculator with this JSON body (see Docs):

{
  "input": {
    "total_potential_companies": 12000,
    "average_contract_value": 8000,
    "icp_percentage": 25,
    "year1_market_share_target": 1,
    "segment_name": "US clinic groups"
  }
}

How does TAM SAM SOM Calculator work?

It applies fixed rules in the ICP Intelligence code to the inputs above and returns text. It does not call an AI model, does not look anything up, and does not store what you type. The web form and the MCP server call the same tool code, so the same input gives the same answer in both.
