MCP & AI workflowsBest MCP servers for sales teams
The MCP servers worth connecting to Claude for B2B sales in 2026: FullEnrich for verified enrichment, Apollo for all-in-one prospecting, HubSpot for CRM, Smartlead for deliverability, Clay for querying your workspace. Start with a data MCP plus a CRM MCP.
Data & enrichmentReverse email lookup: how it works and the best tools
