Nynch
A hosted MCP server that connects Claude to Nynch's relationship-led CRM platform with 42 tools across contact management, pipeline tracking, relationship intelligence, and multi-agent orchestration. You get the usual CRM operations (search contacts, log interactions, move deals through stages) plus relationship scoring across six dimensions, buying committee mapping, and AI-generated next actions. The multi-agent layer lets you register external agents, share context via a key-value store, and hand off tasks between agents with capability matching. Runs over streamable HTTP, requires a Nynch API key with scoped permissions. Reach for this if you're building AI workflows around professional services sales and want relationship context beyond basic contact fields.
