}
}
}
}
Restart Claude Desktop after saving.
Cursor (STDIO)- Open Settings > MCP
- Click Add new MCP server
- Use the following configuration:
- Name:
custify - Command:
npx -y @custify/mcp-server - Environment Variables:
CUSTIFY_API_KEY=your-api-key-here
Add to your .vscode/mcp.json in your workspace root:
{
"servers": {
"custify": {
"command": "npx",
"args": ["-y", "@custify/mcp-server"],
"env": {
"CUSTIFY_API_KEY": "your-api-key-here"
}
}
}
}
Claude Code (CLI)
claude mcp add custify -- npx -y @custify/mcp-server \
--env CUSTIFY_API_KEY=your-api-key-here
ChatGPT (Streamable HTTP)
ChatGPT requires an HTTP-based MCP server. Deploy with Docker:
docker run -d \
-p 3000:3000 \
-e CUSTIFY_API_KEY=your-api-key-here \
ghcr.io/custifyofficial/custify-mcp:latest
Then configure ChatGPT to connect to your server's URL:
https://your-server.example.com/mcp
Other MCP Clients
The Custify MCP server supports two transports:
- STDIO (default): Run
npx @custify/mcp-serverwith theCUSTIFY_API_KEYenvironment variable set. - Streamable HTTP: Set
MCP_TRANSPORT=streamable-httpand the server will listen on port 3000 (configurable viaPORT). The MCP endpoint is/mcp.
Refer to your MCP client's documentation for how to configure an MCP server using either transport.

Environment Variables
| Variable | Required | Default | Description |
|---|---|---|---|
CUSTIFY_API_KEY |
Yes | - | Your Custify API key |
CUSTIFY_API_URL |
No | https://api.custify.com |
Custom API base URL (for different clusters) |
MCP_TRANSPORT |
No | stdio |
Transport mode: stdio or streamable-http |
PORT |
No | 3000 |
HTTP server port (only used with streamable-http transport) |
Docker
Run the server as a Docker container for HTTP-based MCP clients:
docker run -d \
--name custify-mcp \
-p 3000:3000 \
-e CUSTIFY_API_KEY=your-api-key-here \
ghcr.io/custifyofficial/custify-mcp:latest
The MCP endpoint will be available at http://localhost:3000/mcp and a health check endpoint at http://localhost:3000/health.
Security
- Data flow: Your AI tool communicates with the Custify MCP server, which then makes authenticated API calls to the Custify REST API. No data is stored by the MCP server itself.
- API key handling: Your
CUSTIFY_API_KEYis read from environment variables and is never logged, cached, or exposed through MCP responses. When using STDIO transport, the key stays within your local process. When using HTTP transport, ensure your deployment is behind TLS. - Permissions: The MCP server inherits the permissions of your API key. Use a key scoped to the minimum access level your workflows require. Read-only keys will work for all read tools; write tools require a key with write permissions.
- No telemetry: The server does not collect analytics or send data to any third party.
Troubleshooting
"Error: CUSTIFY_API_KEY environment variable is required"Make sure the CUSTIFY_API_KEY environment variable is set in your MCP client configuration. Double-check for typos and ensure there are no extra spaces.
Server not connecting in Claude Desktop
- Verify the config file path is correct for your OS.
- Ensure you have restarted Claude Desktop after editing the configuration.
- Check that
npxis available in your system PATH.
Authentication errors (401)Your API key may be invalid or expired. Generate a new key from Custify Settings > Developer > API Access.
Permission errors (403)The endpoint may not be available for API key access. Check that your Custify account has the required permissions.
Timeout or connection errorsIf using HTTP transport, verify the server is running and accessible. Check that the PORT environment variable matches your deployment configuration. For STDIO transport, ensure no firewall or proxy is blocking local process communication.
Different Custify cluster?If your Custify instance is on a different cluster (e.g., EU), set CUSTIFY_API_URL to your cluster's API URL.
Docker container exits immediatelyCheck the container logs with docker logs custify-mcp. The most common cause is a missing CUSTIFY_API_KEY environment variable.
