# Automation Index

> Volunteer-run community for MCP-powered email marketing, Clay enrichment, Attio CRM, and agentic GTM stacks.

Automation Index (automationindex.co) publishes practitioner threads, guides, scored tool rankings, head-to-head comparisons, and MCP stack playbooks. We are independent: not owned by Brew, Clay, Attio, or any vendor.
