# MCP Vertica
[](https://smithery.ai/server/@nolleh/mcp-vertica)
A Vertica MCP(model-context-protocol) Server
### Example: MCP Server Setting
Create or edit the file your mcp client config file with the following content:
```json
{
"mcpServers": {
"vertica": {
"command": "uvx",
"args": [
"mcp-vertica",
"--host=localhost",
"--db-port=5433",
"--database=VMart",
"--user=dbadmin",
"--password=",
"--connection-limit=10"
]
}
}
}
```
Or with env
```json
{
"mcpServers": {
"vertica": {
"command": "uvx",
"args": ["mcp-vertica"],
"env": {
"VERTICA_HOST":"localhost",
"VERTICA_PORT":5433,
"VERTICA_DATABASE":"VMart",
"VERTICA_USER":"dbadmin",
"VERTICA_PASSWORD":"",
"VERTICA_CONNECTION_LIMIT":10,
"VERTICA_SSL":false,
"VERTICA_SSL_REJECT_UNAUTHORIZED":true
}
}
}
}
```
> [!Note]
>
> - For boolean flags like `--ssl` or `--ssl-reject-unauthorized`, simply add the flag (e.g., `"--ssl"`) to enable it, or omit it to disable.
> - For an empty password, use an empty string as shown above.
