​
Overview

The Connextify MCP server is hosted at https://connextify.com/mcp and follows the Model Context Protocol (MCP) specification. You can connect any MCP-compatible client to interact with your Connextify account.

​
Prerequisites

  • An active Connextify account
  • MCP API key from API Key Settings
  • An MCP-compatible client (Claude Desktop, n8n, etc.)

​
Getting Your MCP API Key

1

Sign In

Log in to your Connextify account at app.connextify.com/login
2

Access Developer Settings

Navigate to Dashboard → API Keys or go to app.connextify.com/dashboard/api-keys
3

Create MCP API Key

Click Create New API Key and select MCP permissions
4

Copy Your Key

Copy your API key - you’ll need it for configuration

​
Installation Methods

The fastest way to install connextify on your desktop is via Smithery. This automatically handles the bridge configuration for you. 
npx -y @smithery/cli install connextify-mcp

​
2. Claude.ai Web & Cloud Tools (SSE)

For the Claude.ai Web interface (Custom Connectors), n8n, or other cloud-based automation tools, use our SSE (Server-Sent Events) transport.

SSE Endpoint

https://connextify.com/mcp/sse

Auth Header

x-mcp-key: YOUR_API_KEY

​
3. Manual Desktop Configuration

If you prefer to configure Claude Desktop manually, add the following to your claude_desktop_config.json: 
{
  "mcpServers": {
    "connextify": {
      "command": "npx",
      "args": [
        "-y",
        "connextify-mcp-server"
      ],
      "env": {
        "CONNEXTIFY_API_KEY": "your_api_key_here"
      }
    }
  }
}
Pro Tip: If your client gives an error like serverURL or command must be specified, ensure you are using the serverURL property name instead of url.

​
2. Automation Tools (n8n, Make, Zapier)

For workflow automation, use the standard HTTP or SSE transport provided by the tool.

n8n Integration

  1. Add an MCP Node
  2. Set URL to https://connextify.com/mcp
  3. Add header x-mcp-key

Custom Webhooks

  1. Use POST https://connextify.com/mcp
  2. Send JSON-RPC 2.0 payload
  3. Header: x-mcp-key

​
3. Connection Property Reference

If you are building your own client or using a custom app, refer to these property mappings to handle different SDK implementations:
RequirementProperty NameValue / Endpoint
SSE Connection URLserverURL or urlhttps://connextify.com/mcp/sse
HTTP API EndpointbaseUrl or pathhttps://connextify.com/mcp
Transport Typetypesse or stdio (via connextify-mcp)
Authentication Headerheadersx-mcp-key: connextify_...
Env Variableenvconnextify_API_KEY

​
4. Direct HTTP API (Manual Exploration)

You can interact with the MCP server directly via raw HTTP requests for testing: You can also interact with the MCP server directly via HTTP: 
# Initialize connection
curl -X POST https://connextify.com/mcp \
  -H "Content-Type: application/json" \
  -H "x-mcp-key: YOUR_MCP_API_KEY" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "initialize",
    "params": {
      "protocolVersion": "2024-11-05",
      "clientInfo": {
        "name": "my-client",
        "version": "1.0.0"
      }
    }
  }'

MCP Endpoints

/mcpGETServer identification and info
/mcp/toolsGETList available tools
/mcp/resourcesGETList available resources
/mcp/promptsGETList available prompts

​
Authentication

The MCP server uses the x-mcp-key header for authentication: 
x-mcp-key: connextify_your_api_key_here
MCP API keys have specific rate limits based on your subscription plan. Check your API Key Settings for current limits.

​
Verification

After configuration, verify the connection:

​
1. Check Server Status

curl https://connextify.com/mcp
Should return server information: 
{
  "name": "connextify-mcp-server",
  "version": "1.1.0",
  "protocolVersion": "2024-11-05"
}

​
2. List Available Tools

curl -X GET https://connextify.com/mcp/tools \
  -H "x-mcp-key: YOUR_MCP_API_KEY"

​
3. Test a Simple Command

curl -X POST https://connextify.com/mcp \
  -H "Content-Type: application/json" \
  -H "x-mcp-key: YOUR_MCP_API_KEY" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/list"
  }'

​
Troubleshooting

  • Verify your API key is correct and starts with connextify_
  • Ensure you’re using the x-mcp-key header (not Authorization)
  • Check that your API key hasn’t been revoked
  • Your plan may not include MCP access
  • Check your plan limits in Developer Settings
  • Upgrade to Pro or Enterprise for MCP access
  • MCP operations are rate-limited per your plan
  • Wait for the rate limit window to reset
  • Consider upgrading for higher limits
  • Verify network connectivity to connextify.com
  • Check if your firewall allows HTTPS connections
  • Try the health endpoint: https://connextify.com/mcp/health
