### Example: MCP Server Setting
Create or edit the file your mcp client config file with the following content:
#### UVX
```json
{
"mcpServers": {
"vertica": {
"command": "uvx",
"args": ["mcp-vertica"],
"env": {
"VERTICA_HOST": "localhost",
"VERTICA_PORT": 5433,
"VERTICA_DATABASE": "VMart",
"VERTICA_USER": "dbadmin",
"VERTICA_PASSWORD": "test_password",
"VERTICA_CONNECTION_LIMIT": 10,
"VERTICA_SSL": false,
"VERTICA_SSL_REJECT_UNAUTHORIZED": true
}
}
}
}
```
Or with args
```json
{
"mcpServers": {
"vertica": {
"command": "uvx",
"args": [
"mcp-vertica",
"--host=localhost",
"--db-port=5433",
"--database=VMart",
"--user=dbadmin",
"--password=test_password",
"--connection-limit=10"
]
}
}
}
```
#### Docker
```json
{
"mcpServers": {
"vertica": {
"command": "docker",
"args": ["run", "-i", "--rm", "nolleh/mcp-vertica"],
"env": {
"VERTICA_HOST": "localhost",
"VERTICA_PORT": 5433,
"VERTICA_DATABASE": "VMart",
"VERTICA_USER": "dbadmin",
"VERTICA_PASSWORD": "test_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.

## Installation
### Installing via Smithery
To install Vertica Database Connector for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@nolleh/mcp-vertica):
```bash
npx -y @smithery/cli install @nolleh/mcp-vertica --client claude
```
### Installing Manually
Open your favorite mcp client's config file, then configure with `uvx mcp-vertica`
[Example: Mcp Server Setting](#example%3A-mcp-server-setting)
## Development
### Debug Mode
When running with Docker, you can enable debug logging by setting the `DEBUG` environment variable:
```bash
# Run with maximum verbosity (-vvv)
docker run -e DEBUG=3 -e VERTICA_HOST=localhost ... nolleh/mcp-vertica:latest
# Run with medium verbosity (-vv)
docker run -e DEBUG=2 -e VERTICA_HOST=localhost ... nolleh/mcp-vertica:latest
# Pass additional arguments
docker run -e EXTRA_ARGS="--connection-limit=20" -e VERTICA_HOST=localhost ... nolleh/mcp-vertica:latest
```
In `docker-compose.yml`:
```yaml
environment:
DEBUG: 3 # 0=none, 1=-v, 2=-vv, 3=-vvv
EXTRA_ARGS: "--connection-limit=20" # Optional additional arguments
```
#### Appendix: For Testing, VerticaDB Docker Compose Example
```yaml
version: "3.8"
services:
vertica:
# image: vertica/vertica-ce:11.1.0-0
image: vertica/vertica-ce:latest
platform: linux/amd64
container_name: vertica-ce
environment:
VERTICA_MEMDEBUG: 2
ports:
- "5433:5433"
- "5444:5444"
volumes:
- vertica_data:/home/dbadmin/VMart
healthcheck:
test:
[
"CMD",
"/opt/vertica/bin/vsql",
"-h",
"localhost",
"-d",
"VMart",
"-U",
"dbadmin",
"-c",
"SELECT 1",
]
interval: 10s
timeout: 5s
retries: 5
start_period: 30s
restart: unless-stopped
mcp-vertica:
image: nolleh/mcp-vertica:latest
container_name: mcp-vertica
ports:
- "8081:8081"
environment:
# Transport mode
TRANSPORT: http
PORT: 8081
# Debug settings (0=none, 1=-v, 2=-vv, 3=-vvv)
DEBUG: 3 # Set to 3 for maximum verbosity
# Extra command line arguments (optional)
# EXTRA_ARGS: "--some-flag"
# Vertica connection settings
VERTICA_HOST: vertica
VERTICA_PORT: 5433
VERTICA_DATABASE: VMart
VERTICA_USER: dbadmin
VERTICA_PASSWORD: ""
VERTICA_CONNECTION_LIMIT: 10
VERTICA_SSL: "false"
depends_on:
vertica:
condition: service_healthy
volumes:
vertica_data:
driver: local
```
Then run server by following instruction [Example: Mcp Server Setting](#example%3A-mcp-server-setting),
Then see everything works as fine
