## Research notes
Borderline for this category - primarily a hiring/tech-stack signals and trigger tool, not a contact-database or email-finder product; could arguably sit in signals-intent-abm instead. Included because GTM engineers commonly wire it into enrichment/waterfall pipelines for firmographic + hiring context. 200 credits/month free tier; paid plans from $59/month; MCP calls consume the same credit pool as REST calls. 2026-09-07: Official MCP registry carries com.theirstack/theirstack (DNS-verified theirstack.com namespace) with remote https://api.theirstack.com/mcp (https://api.theirstack.com/mcp/).
