IMPACT MCP v2.2.27

Hypothesis-Driven B2B Positioning Engine: 8 tools implementing the IMPACT framework for strategic positioning and go-to-market messaging.

Use it hosted (no install)

Add https://impact.gtmhelix.com/mcp to Claude or ChatGPT as a custom connector. It needs no sign-in and always runs the newest version (2.2.27). The same tools run as a free web app with a form per tool at https://impact.gtmhelix.com/, and the setup steps are at https://impact.gtmhelix.com/connect/.

The npm package below is an older version (2.0.0 on npm on 27 September 2026) until the next npm release. Use it only if you need a local stdio server.

Quick Start

bash

# Run directly with npx
npx -y @shashwatgtmalpha/impact-mcp

Claude Desktop Configuration

Add to your claude_desktop_config.json:

json

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

The IMPACT Framework

IMPACT is a hypothesis-driven positioning methodology for B2B companies:

Phase	Focus	Tool
Identify	Champions & Buyer Personas	`impact_identify_champions`
Map	Alternatives & Competitive Landscape	`impact_map_alternatives`
Pinpoint	Value Proposition & Differentiation	`impact_pinpoint_value`
Anchor	Market Selection & Beachhead	`impact_anchor_market`
Craft	Messaging & Positioning Statement	`impact_craft_message`
Translate	Channel-Specific Execution	`impact_translate_execution`

Tools and inputs

Generated on 27 September 2026 from the server's own tool list and checked again on 27 October 2026 against tools/list of impact-mcp 2.2.27 (tool descriptions rewritten that day) (the same code as the hosted MCP address), so every tool name, title, description and input below is exactly what the server accepts. Every tool is read-only.

#	Tool	Title	What it does
1	`impact_get_framework`	IMPACT Framework Guide	Returns the IMPACT positioning method step by step: identify champions, map alternatives, pinpoint value, anchor in a market, craft the message and translate it to execution, with a template or checklist for each step. An optional focus phase returns one step only, and your sector adds that sector's buyer roles, measures and proof points.
2	`impact_identify_champions`	Identify Champions	Takes what your product does and the problem it solves, and returns hypotheses for who buys it: the champion, the economic buyer, the technical influencer, commercial and control reviewers and daily users, with warning signs of an anti-champion, a path to develop the champion and what to give them. Optional company name, target company type, price point and sector fit the roles to your market. These are roles to test, not named people.
3	`impact_map_alternatives`	Map Alternatives	Takes your product and its category, and returns a map of the alternatives your buyers weigh: one card for each competitor you name, the status-quo options you list and doing nothing, where you can lead, and discovery questions to learn more. Optional competitor weaknesses and your strengths fill the cards, and your sector adds its questions and objections. It uses only what you give and says what would sharpen the map.
4	`impact_pinpoint_value`	Pinpoint Value	Takes your target customer, the main outcome they get and what you do that others do not, and returns value proposition statements in three versions, a value matrix for your own figures, proof points ranked from customer results to social proof, versions for different audiences and channels, and questions to test the value. Optional product name, category, customer results and business model shape it.
5	`impact_anchor_market`	Anchor Market	Takes what your product does and the segments you are weighing, and returns a beachhead market choice: your segments ranked from your own customers, pain and deal size when you give all three (the answer says which method it used), otherwise scored on keywords in their names; a TAM/SAM/SOM calculation that uses only the company counts, deal size and percentages you give; a three-year expansion path and an ICP hypothesis for the chosen segment. It never chooses a segment you did not name: without segments it recommends none and explains how to find yours from your own customers.
6	`impact_craft_message`	Craft Message	Takes your target customer, the key benefit and what sets you apart, and returns a positioning statement (full and one sentence), a message hierarchy from tagline to three supporting pillars, versions for different audiences, objection handling and ways to test the message. Optional product name, customer need, category, main competitor and business model fit it to your market. It writes from your own words, in whole sentences.
7	`impact_translate_execution`	Translate Execution	Takes a positioning statement, your target customer and the key benefit, and returns copy to edit for the channels you choose: a website hero, a LinkedIn tagline and post drafts, a three-email cold sequence, a sales deck outline and a 15-minute demo script, with calls to action that fit your business model and the order to work the channels in. Optional channels, product name and business model shape it.
8	`impact_full_audit`	IMPACT Full Audit	Takes what your product does, your target customer and the problem you solve, and returns a positioning audit: an input completeness score for each IMPACT step, the proof you already have, your current positioning checked in words, a recommended positioning with tagline options, a 30-day action plan and the measures to track. Optional company name, differentiation, competitors, current positioning, customer feedback and business model make it fuller. The score measures how complete your inputs are, not how strong your positioning is.

About the IMPACT Framework

The IMPACT framework was developed by Shashwat Ghosh based on 24+ years in B2B and 10+ years of fractional experience. It addresses the common failure mode of B2B positioning: starting with features instead of market hypotheses.

Key Principles:

Hypothesis-driven: Test assumptions before committing
Outside-in: Start with customer, not product
Iterative: Refine based on market feedback
Execution-focused: Bridge strategy to implementation

Hosted connector (Streamable HTTP)

The same tools are also available as a hosted MCP server, so they work in Claude on the web, desktop and mobile without installing anything.

Server URL: https://impact.gtmhelix.com/mcp
Transport: Streamable HTTP (stateless, JSON responses). Authentication: none.
Setup guide: https://impact.gtmhelix.com/connect/
In Claude: Customize, then Connectors, then Add custom connector, and paste the server URL.
In Claude Code: claude mcp add --transport http impact https://impact.gtmhelix.com/mcp

The npm package (stdio) and the hosted server run the same createServer() code in src/index.ts.

The tool reference (https://impact.gtmhelix.com/docs/) is generated from the code. Where it differs from the parameter tables earlier in this README, the tool reference is correct.

Privacy Policy

Full policy: https://impact.gtmhelix.com/privacy/ (also in PRIVACY.md).

Data collection: the hosted server receives only the tool name and the inputs of each tool call. The npm package runs on your computer and sends nothing to us.
Use and storage: inputs are used only to build that call's reply. Nothing is stored: no database, no files, no cache, no logging of inputs or outputs by our code.
Third-party sharing: none by us. Netlify hosts the server and processes requests under its own policy (https://www.netlify.com/privacy/). Fonts are served from this site, so loading a page contacts no one else.
Retention: we keep no tool inputs or outputs. Netlify keeps its own platform logs under its policy.
