Nynch MCP Server

Website: www.nynch.com · Developer docs: www.nynch.com/developers · Endpoint: https://app.nynch.com/mcp

The official, hosted Model Context Protocol server for Nynch, the AI CRM for consultants and fractionals who win high-value deals based on relationships.

50 tools across 6 categories: CRM read, CRM write, relationship intelligence, firm intelligence, context query, and multi-agent orchestration.

Endpoint

https://app.nynch.com/mcp

Transport: JSON-RPC 2.0 over Streamable HTTP. The server is stateless (no session to manage) and negotiates the protocol version with your client — it speaks 2025-11-25, 2025-06-18, and 2025-03-26.

The older endpoint https://crcrwtjzqzinfzokianr.supabase.co/functions/v1/mcp-server still answers, but it is deprecated. Use https://app.nynch.com/mcp in new configs.

In Claude, open Settings → Connectors → Add custom connector and enter https://app.nynch.com/mcp. Click Connect, sign in with your Nynch account and approve access. Revoke access any time in Nynch under Settings → Integrations → AI hosts.
