Claude, ChatGPT, Cursor, VS Code and Windsurf

Use ICP Intelligence in Claude, ChatGPT, Cursor, VS Code and Windsurf

For marketing, sales and customer success teams. The decision: whether to run ICP Intelligence in a browser with no sign in, or inside the assistant you already use.

You need one address and no sign in. Pick your assistant and follow its steps.

Where it works: in a web browser with no sign in, in Claude as a connector (including Claude Code and Cowork), in ChatGPT, in Gemini through the Helix GTM Suite skills package, and in Cursor, VS Code and Windsurf as an MCP server.

How it looks in Claude

Ask in plain words and Claude calls the connector. The example uses ICP Intelligence; every connector works the same way.

All six: 12,400 npm downloads, first release to 4 November 2026 (GTM Alpha first released 8 September 2025, the other five in January 2026). npm also counts automated downloads.

Free to install. Seven are published in Anthropic's plugin directory; B2B ICP and Customer Insight is in review; B2B Deal Execution is public on GitHub and installable. With the 48 connector tools in six connectors, that makes 85 free tools and skills. Each plugin page shows real answers from a test run.

A real answer from the ICP Intelligence connector. The question gave no match rate or share, so the tool used labelled examples.

Quick start: three steps

Add this MCP server address to Claude, ChatGPT, Cursor, VS Code or Windsurf: https://icp-intelligence.gtmhelix.com/mcp
Leave the sign in fields empty. The steps for each assistant are below.
Ask in plain words, for example: Use ICP Intelligence to do a deep dive on these customers for our spend management software: mid-size manufacturers with 300 to 3,000 employees and large field sales teams, IT services firms with heavy travel spend, distributors with many branches.

Try these prompts

Use ICP Intelligence to do a deep dive on these customers for our spend management software: mid-size manufacturers with 300 to 3,000 employees and large field sales teams, IT services firms with heavy travel spend, distributors with many branches.
Calculate TAM, SAM and SOM with ICP Intelligence: 9,000 potential companies, average contract value $24,000, 25% fit our ICP, year one share target 1%.
Map the buyer group for spend management software with ICP Intelligence. Deal size $24,000 ACV, target company size 300 to 3,000 employees, typical champion Finance Controller.

When a tool is not enough: if the decision needs more than one answer, talk it through in a call. Book 45 minutes with Shashwat.

Before you connect

Claude plan: any. Custom connectors work on Claude's Free, Pro, Max, Team and Enterprise plans; the Free plan allows one custom connector.
Team or Enterprise: only an Owner can add a custom connector, under Organization settings, Connectors, Add, Custom, Web. Members then turn it on under Customize, Connectors.
Accounts and keys: none. There is no sign in and no API key.
Local use: the npm package needs Node.js 18 or later.

What ICP Intelligence does and does not do

All 9 tools are read only: each one builds a text answer from the inputs you give it and changes nothing anywhere. What you type is used once to build the answer and is not stored or logged. It is not ideal for:

Teams looking for a list of companies to target: the tools describe and score profiles from your data, but they do not find companies.
Teams that want market sizing without their own numbers: TAM, SAM and SOM are built from the figures you enter, and an ICP match rate or market share you leave out is filled with a labelled example (30% and 3%).
Teams that need saved models or CRM sync: answers are not stored and no CRM is connected.
Teams that want answers written to their CRM or other tools: no tool can do that.

The MCP server address

https://icp-intelligence.gtmhelix.com/mcp

It uses Streamable HTTP, is stateless and needs no sign in. All 9 tools are read only. The older address https://icp-intelligence-mcp.netlify.app/mcp still answers directly for anyone who set it up before.

Tools:

ICP Deep Dive: Helps you decide which customers to go after next. You give your best customers, as a list (industry, size, contract value, sales cycle, tech stack, buying trigger, champion title) or in your own words. You get the patterns they share, with ties named as ties, the budget shown as the contract value range seen in your customers, recommendations, and sector notes when your inputs name a supported sector. It works only from what you give and looks nothing up.
ICP Scoring Model: Helps you decide which leads are worth a seller's time. You give the criteria that matter, how important each one is and, if you know it, what goes with success. You get a lead scoring template: example point weights set by importance level, example points for each value you list, a scorecard and tier bands to adjust, with sector notes when your inputs name a supported sector. Your success pattern is matched to your criteria; it does not set the weights.
Buyer Group Analyzer: Helps you decide who else must agree before a deal can close. You give what you sell, the deal size, the company size, your champion and any stakeholders you know. You get a buying group map with your stakeholders placed by their titles (economic buyer, technical evaluator, reviewers, users), each role's concern and message prompts, an influence map and discovery questions, with sector roles and questions when your inputs name a supported sector. Roles from titles are hypotheses to confirm.
TAM SAM SOM Calculator: Helps you decide how big your market is, counted bottom up. You give how many companies could buy and your annual contract value in dollars, plus your ICP match rate and year 1 share if you have them. You get TAM, SAM and SOM with the arithmetic and assumptions shown and a summary for an investor deck. It is a calculator, not a data source: a rate you leave out is filled with a labelled example, and sector notes are added when your inputs name a supported sector.
Lookalike Signal Generator: Helps you decide how to find more accounts like your best ones. You give your ICP's company profile, technologies, champion titles and buying triggers, and optionally what you sell and the platforms you use. You get targeting criteria and search queries for each platform, one signal for each trigger, and search keywords from what you sell and the sector. It writes criteria, not data: it finds no companies or contacts.
Account Prioritization: Helps you decide which accounts to work first. You give your accounts with fit, intent and relationship scores from 0 to 100 and a timing, plus optional weights. You get a ranked list from a weighted score, with a tier for each account, the points its timing earned and the factor that added the most points.
ICP Gap Analysis: Helps you decide whether you are selling to the customers you meant to. You give your current customer base, your ideal customer profile and, if you have them, current and target metrics. You get what the ideal profile has that the current base lacks, metric gaps from your own figures, causes to check and actions that fit your business model, with sector notes when your inputs name a supported sector.
ICP Evolution Tracker: Helps you decide whether your ICP should change after recent wins and losses. You give your current ICP, recent wins, recent losses and market changes. You get a candidate change for each (an addition to test, a disqualifier to test, an implication to check), a draft of the updated ICP, the roles your ICP does not name, the loss reasons to tag and what to pull from your CRM. It does not compute win rates; check each candidate against your CRM.
ICP Interview Synthesizer: Helps you decide what your customer interviews mean for your ICP. You give structured notes, one per interview: the customer, the role, pain points, buying triggers, value realized and key quotes. You get the pain points, objections, buying triggers, value realized and champion roles across the interviews, quotes kept word for word, discovery questions and sector notes. It does not take full transcripts; give only the points and quotes you want analyzed.

Claude (web, desktop and mobile)

Open Customize, then Connectors, select +, then Add custom connector.
Name: ICP Intelligence. Remote MCP server URL: https://icp-intelligence.gtmhelix.com/mcp.
Leave the sign in fields empty and select Add.
In a chat, turn the connector on from the tools menu and ask, for example: Use ICP Intelligence to do a deep dive on these customers for our spend management software: mid-size manufacturers with 300 to 3,000 employees and large field sales teams, IT services firms with heavy travel spend, distributors with many branches.

On Team and Enterprise, an Owner adds the connector first under Organization settings, Connectors, Add, Custom, Web; each member then turns it on under Customize, Connectors.

Claude Code

Terminal

claude mcp add --transport http icp-intelligence https://icp-intelligence.gtmhelix.com/mcp

ChatGPT

ChatGPT can use remote MCP servers as custom connectors on plans that allow developer mode. In ChatGPT's settings, open the connectors (apps) section, turn on developer mode if your plan requires it, create a connector with the URL https://icp-intelligence.gtmhelix.com/mcp and no authentication, then enable it in a chat. Menu names change between ChatGPT releases; OpenAI's help centre has the current path.

Cursor

Add this to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

~/.cursor/mcp.json

{
  "mcpServers": {
    "icp-intelligence": {
      "url": "https://icp-intelligence.gtmhelix.com/mcp"
    }
  }
}

VS Code (GitHub Copilot agent mode)

Add this to .vscode/mcp.json in your project:

.vscode/mcp.json

{
  "servers": {
    "icp-intelligence": {
      "type": "http",
      "url": "https://icp-intelligence.gtmhelix.com/mcp"
    }
  }
}

Windsurf

Add this to ~/.codeium/windsurf/mcp_config.json:

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "icp-intelligence": {
      "serverUrl": "https://icp-intelligence.gtmhelix.com/mcp"
    }
  }
}

Other assistants, or no internet access

Any MCP client that supports Streamable HTTP can use the address above with no authentication. For a client that only runs local servers, use the npm package, which runs these tools on your own computer over stdio (npm can lag behind this site until a new version is published):

MCP client config (npm package)

{
  "mcpServers": {
    "icp-intelligence": {
      "command": "npx",
      "args": [
        "-y",
        "@shashwatgtmalpha/icp-intelligence-mcp"
      ]
    }
  }
}

How to read the answer

When your assistant calls an ICP Intelligence tool, the server returns a structured Markdown analysis built from fixed rules, including market sizing calculations, scoring models, or account tier rankings. Any benchmark, match rate, share, or weight you did not supply is labelled as an example figure to replace with your own.

What to do next

Founder: Add the connector URL in your assistant and run ICP Deep Dive or TAM, SAM, SOM Calculator with your current customer and pricing numbers.
CEO: Share this setup page with your revenue and marketing leads so everyone sizes markets and scores accounts with the same rules.
CMO: Connect ICP Intelligence in your assistant to run ICP Deep Dive, Buyer Group Analyzer, and Lookalike Signal Generator.
CRO: Use the connected ICP Scoring Model and Account Prioritization tools to rank target accounts into Tiers A to D.
Demand generation head: Run Lookalike Signal Generator and Buyer Group Analyzer in your assistant to build account lists and role-based outreach plays.

Why come back

Come back when you add a new assistant, onboard a teammate, or check the example prompts and payload limits. The tool applies the same fixed rules every time. It does not call an AI model, and this site does not keep what you enter.
