Helix GTM Suite: 89 Free B2B GTM Tools & Agent Skills

Built by Shashwat Ghosh, Co-Founder and Fractional CMO, Helix GTM Consulting (Free Tools Hub).

For founders, CMOs and CROs of growth stage B2B firms and their marketing, sales and customer success teams. It helps a lean team decide which go-to-market motion should lead, which customers to target, how to position, whether a deal or account is at risk, and what it can publish, with a proven method it can run today in the tools it already uses. You give each tool or skill your own facts; you get a scored, structured answer, with every missing fact marked for you to fill.

This repository provides a single installable package for Google Antigravity, Gemini CLI (Gemini), Claude Code / Cowork, ChatGPT, Cursor, and VS Code, connecting:

• 6 Hosted Streamable HTTP MCP Connectors (52 Deterministic Tools): Zero sign-in, stateless, rule-based TypeScript engines (gtmalpha, craft-gtm, craft-content, impact, icp-intelligence, revenue-enablement).
• 9 B2B GTM Claude Plugins (37 Agent Skills), plus companion skills: Built on the EPIC, IMPACT, CRAFT, and GUARD frameworks.

That is 89 free tools and skills: 52 tools in 6 connectors and 37 skills in 9 plugins.
