How to use GTM Index
GTM Index is the public catalog of GTM engineers, practitioner playbooks, and the tools they stack. Browse people, playbooks, tools, and jobs on gtmindex.io without an account. Agents should start at the machine index or the no-key WebMCP endpoint — not by guessing paths.
Find people and playbooks
Search the index for GTM engineers by name, skill, stack, company, or location. Read 40 sourced playbooks with steps, stack, and the original link. The tools catalog lists about 500 products GTM engineers actually run.
Call GTM Index from an agent
No API key. POST JSON-RPC to the open WebMCP endpoint for search_people, search_tools, get_playbook, and stack_cooccurrence. Same-origin docs live under GTM Index developer resources. Paginate people. Do not request the full people list in one call.

The role
What is a GTM Engineer?
A hybrid technical role that builds and automates the infrastructure powering a company’s revenue engine. Instead of manually running sales and marketing campaigns, GTMes use data enrichment, workflow automation (Clay, Zapier, Make), APIs, and AI to scale lead gen, data routing, and outreach.
Enrichment
Clean records, waterfalls, ICP scoring on every new row.Automation
Clay, Zapier, Make, n8n — workflows instead of headcount.APIs & AI
Routing, research agents, and outreach that runs itself.
