# Use environment variable for endpoint
## Transport Customizations
The below server customizations are available when running with `sse` and `streamable-http` transports.

| Server Parameter | CLI Arguments | Environment Variable | Default |
|-----------|--------------|---------------------|------------------|
| Host | --server-host | SNOWFLAKE_MCP_HOST | "0.0.0.0"
| Port | --port | SNOWFLAKE_MCP_PORT | 9000
| Endpoint | --endpoint | SNOWFLAKE_MCP_ENDPOINT | /mcp

Example:
```bash
export SNOWFLAKE_MCP_ENDPOINT="/my-mcp"
uvx snowflake-labs-mcp --service-config-file config.yaml --transport streamable-http
