Nynch MCP server

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

Python (MCP SDK)

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
