Configuring Claude Desktop
Direct Usage Configuration
If you installed the package globally, configure Claude Desktop with:
{
"mcpServers": {
"sqlite": {
"command": "npx",
"args": [
"-y",
"@executeautomation/database-server",
"/path/to/your/database.db"
]
},
"sqlserver": {
"command": "npx",
"args": [
"-y",
"@executeautomation/database-server",
"--sqlserver",
"--server", "your-server-name",
"--database", "your-database-name",
"--user", "your-username",
"--password", "your-password"
]
}
}

"command": "node",
"args": [
"/absolute/path/to/mcp-database-server/dist/src/index.js",
"/path/to/your/database.db"
]
},
"sqlserver": {
"command": "node",
"args": [
"/absolute/path/to/mcp-database-server/dist/src/index.js",
"--sqlserver",
"--server", "your-server-name",
"--database", "your-database-name",
"--user", "your-username",
"--password", "your-password"
]
}
}
