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.

The IMPACT Framework

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

Tools and inputs

Generated on 27 September 2026 from the server's own tool list and checked again on 17 October 2026 against tools/list of impact-mcp 2.2.27 (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.

Inputs of each tool

1. IMPACT Framework Guide (impact_get_framework)

2. Identify Champions (impact_identify_champions)

3. Map Alternatives (impact_map_alternatives)

4. Pinpoint Value (impact_pinpoint_value)

5. Anchor Market (impact_anchor_market)

6. Craft Message (impact_craft_message)

7. Translate Execution (impact_translate_execution)

8. IMPACT Full Audit (impact_full_audit)

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.
