MCP Server (AI Integration)

Connect Claude or other AI assistants to SerenAI:

# Claude Code (recommended - no local install needed)
claude mcp add --scope user --transport http seren https://mcp.serendb.com/mcp

Or configure manually for Claude Desktop:

{
  "mcpServers": {
    "seren": {
      "url": "https://mcp.serendb.com/mcp",
      "transport": "streamable-http"
    }
  }
}

See mcp/README.md for local server setup and all configuration options.

CLI

# Install from source (see Installation below)
cargo install --path cli

# Login and start managing databases
seren auth login
seren projects list
seren projects create --name my-project --region aws-us-east-1

use seren::{Client, ClientConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = ClientConfig::new("seren_your_api_key");
    let client = Client::from_config(&config)?;

    let projects = client.list_projects(None, None, None).await?;
    println!("Found {} projects", projects.into_inner().data.len());
