Nynch MCP Server

A hosted Model Context Protocol server that gives AI agents full access to Nynch — a relationship-led growth platform for consultants and professional services firms.

47 tools across 5 categories: CRM read, CRM write, relationship intelligence, context query, and multi-agent orchestration.

Endpoint

https://crcrwtjzqzinfzokianr.supabase.co/functions/v1/mcp-server

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.

Quick Start

1. Get an API Key

Sign up at nynch.com, then go to Settings → Integrations → Claude & AI Assistants and create an API key.

Scopes:

• read — Search, browse, and retrieve data
• read-write — Read + create, update, delete records
• admin — Full access including agent orchestration

2. Configure Your Client

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "nynch": {
      "url": "https://crcrwtjzqzinfzokianr.supabase.co/functions/v1/mcp-server",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "nynch": {
      "url": "https://crcrwtjzqzinfzokianr.supabase.co/functions/v1/mcp-server",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Python (MCP SDK)

from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client

async with streamablehttp_client(
    "https://crcrwtjzqzinfzokianr.supabase.co/functions/v1/mcp-server",
    headers={"Authorization": "Bearer YOUR_API_KEY"}
) as (read, write, _):
    async with ClientSession(read, write) as session:
        await session.initialize()
        result = await session.call_tool("search_contacts", {"query": "Acme Corp"})
        print(result)

3. Start Using Tools

Your AI client discovers available tools automatically. Ask it to search contacts, check your pipeline, create tasks, or analyze relationships.

Discover and read bounded slices of Nynch and connected-app context, metadata-first. Read-only — never accepts raw SQL.

MCP Resources

Agent Orchestration

Nynch supports multi-agent workflows where AI agents register, share context, and hand off tasks:

• Register with a name, capabilities, and archetype (producer, consumer, coordinator, critic)
• Share state via a key-value context store with namespaces and TTLs
• Route tasks by agent name or capability matching
• Track liveness with heartbeats

Rate Limits

• 1,000 requests per hour per API key
