It may still contain bugs and unexpected behavior. Use caution with production data and ensure you have backups. ## Features and Roadmap * **SQLite compatibility** for SQL dialect, file formats, and the C API [see [document](COMPAT.md) for details] * **Change data capture (CDC)** for real-time tracking of database changes. * **Multi-language support** for * [Go](https://github.com/tursodatabase/turso-go) * [JavaScript](bindings/javascript) * [Java](bindings/java) * [Python](bindings/python) * [Rust](bindings/rust) * [WebAssembly](bindings/javascript) * **Asynchronous I/O** support on Linux with `io_uring` * **Cross-platform** support for Linux, macOS, Windows and browsers (through WebAssembly) * **Vector support** support including exact search and vector manipulation * **Improved schema management** including extended `ALTER` support and faster schema changes. The database has the following experimental features: * **`BEGIN CONCURRENT`** for improved write throughput using multi-version concurrency control (MVCC). * **Encryption at rest** for protecting the data locally. * **Incremental computation** using DBSP for incremental view mainatenance and query subscriptions. The following features are on our current roadmap: * **Vector indexing** for fast approximate vector search, similar to [libSQL vector search](https://turso.tech/vector). ## Getting Started Please see the [Turso Database Manual](docs/manual.md) for more information. <details> <summary>💻 Command Line</summary> You can install the latest `turso` release with: ```shell curl --proto '=https' --tlsv1.2 -LsSf \ https://github.com/tursodatabase/turso/releases/latest/download/turso_cli-installer.sh | sh ``` Then launch the interactive shell: ```shell $ tursodb ``` This will start the Turso interactive shell where you can execute SQL statements: ```console Turso Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database turso> CREATE TABLE users (id INT, username TEXT); turso> INSERT INTO users VALUES (1, 'alice'); turso> INSERT INTO users VALUES (2, 'bob'); turso> SELECT * FROM users; 1|alice 2|bob ``` You can also build and run the latest development version with: ```shell cargo run ``` If you like docker, we got you covered.

For detailed instructions on how to use Turso Database with java, please refer to the [README.md under bindings/java](bindings/java/README.md). </details> <details> <summary>🤖 MCP Server Mode</summary> The Turso CLI includes a built-in [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that allows AI assistants to interact with your databases. Start the MCP server with: ```shell tursodb your_database.db --mcp ``` ### Configuration Add Turso to your MCP client configuration: ```json { "mcpServers": { "turso": { "command": "/path/to/.turso/tursodb", "args": ["/path/to/your/database.db", "--mcp"] } } } ``` ### Available Tools The MCP server provides nine tools for database interaction: 1. **`open_database`** - Open a new database 2. **`current_database`** - Describe the current database 3. **`list_tables`** - List all tables in the database 4. **`describe_table`** - Describe the structure of a specific table 5. **`execute_query`** - Execute read-only SELECT queries 6. **`insert_data`** - Insert new data into tables 7. **`update_data`** - Update existing data in tables 8. **`delete_data`** - Delete data from tables 9. **`schema_change`** - Execute schema modification statements (CREATE TABLE, ALTER TABLE, DROP TABLE) Once connected, you can ask your AI assistant: - "Show me all tables in the database" - "What's the schema for the users table?" - "Find all posts with more than 100 upvotes" - "Insert a new user with name 'Alice' and email '[email protected]'" ### MCP Clients <details> <summary>Claude Code</summary> If you're using [Claude Code](https://claude.ai/code), you can easily connect to your Turso MCP server using the built-in MCP management commands: #### Quick Setup 1. **Add the MCP server** to Claude Code: ```bash claude mcp add my-database -- tursodb ./path/to/your/database.db --mcp ``` 2. **Restart Claude Code** to activate the connection 3. **Start querying** your database through natural language! #### Command Breakdown ```bash claude mcp add my-database -- tursodb ./path/to/your/database.db --mcp # ↑ ↑ ↑ ↑ # | | | | # Name | Database path MCP flag # Separator ``` - **`my-database`** - Choose any name for your MCP server - **`--`** - Required separator between Claude options and your command - **`tursodb`** - The Turso database CLI - **`./path/to/your/database.db`** - Path to your SQLite database file - **`--mcp`** - Enables MCP server mode #### Example Usage ```bash # For a local project database cd /your/project claude mcp add my-project-db -- tursodb ./data/app.db --mcp # For an absolute path claude mcp add analytics-db -- tursodb /Users/you/databases/analytics.db --mcp # For a specific project (local scope) claude mcp add project-db --local -- tursodb ./database.db --mcp ``` #### Managing MCP Servers ```bash # List all configured MCP servers claude mcp list # Get details about a specific server claude mcp get my-database # Remove an MCP server claude mcp remove my-database ``` </details> <details> <summary>Claude Desktop</summary> For Claude Desktop, add the configuration to your `claude_desktop_config.json` file: ```json { "mcpServers": { "turso": { "command": "/path/to/.turso/tursodb", "args": ["./path/to/your/database.db.db", "--mcp"] } } } ``` </details> <details> <summary>Cursor</summary> For Cursor, configure MCP in your settings: 1. Open Cursor settings 2. Navigate to Extensions → MCP 3. Add a new server with: - **Name**: `turso` - **Command**: `/path/to/.turso/tursodb` - **Args**: `["./path/to/your/database.db.db", "--mcp"]` Alternatively, you can add it to your Cursor configuration file directly. </details> ### Direct JSON-RPC Usage The MCP server runs as a single process that handles multiple JSON-RPC requests over stdin/stdout. Here's how to interact with it directly: #### Example with In-Memory Database ```bash cat << 'EOF' | tursodb --mcp {"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2024-11-05", "capabilities": {}, "clientInfo": {"name": "client", "version": "1.0"}}} {"jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": {"name": "schema_change", "arguments": {"query": "CREATE TABLE users (id INTEGER, name TEXT, email TEXT)"}}} {"jsonrpc": "2.0", "id": 3, "method": "tools/call", "params": {"name": "list_tables", "arguments": {}}} {"jsonrpc": "2.0", "id": 4, "method": "tools/call", "params": {"name": "insert_data", "arguments": {"query": "INSERT INTO users VALUES (1, 'Alice', '[email protected]')"}}} {"jsonrpc": "2.0", "id": 5, "method": "tools/call", "params": {"name": "execute_query", "arguments": {"query": "SELECT * FROM users"}}} EOF ``` #### Example with Existing Database ```bash # Working with an existing database file cat << 'EOF' | tursodb mydb.db --mcp {"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2024-11-05", "capabilities": {}, "clientInfo": {"name": "client", "version": "1.0"}}} {"jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": {"name": "list_tables", "arguments": {}}} EOF ``` </details> ## Contributing We'd love to have you contribute to Turso Database! Please check out the [contribution guide] to get started. ### Found a data corruption bug? Get up to $1,000.00 SQLite is loved because it is the most reliable database in the world. The next evolution of SQLite has to match or surpass this level of reliability. Turso is built with [Deterministic Simulation Testing](simulator/) from the ground up, and is also tested by [Antithesis](https://antithesis.com). Even during Alpha, if you find a bug that leads to a data corruption and demonstrate how our simulator failed to catch it, you can get up to $1,000.00. As the project matures we will increase the size of the prize, and the scope of the bugs. More details [here](https://turso.algora.io). You can see an example of an awarded case on [#2049](https://github.com/tursodatabase/turso/issues/2049). Turso core staff are not eligible. ## FAQ ### Is Turso Database ready for production use? Turso Database is currently under heavy development and is **not** ready for production use. ### How is Turso Database different from Turso's libSQL? Turso Database is a project to build the next evolution of SQLite in Rust, with a strong open contribution focus and features like native async support, vector search, and more. The libSQL project is also an attempt to evolve SQLite in a similar direction, but through a fork rather than a rewrite. Rewriting SQLite in Rust started as an unassuming experiment, and due to its incredible success, replaces libSQL as our intended direction. At this point, libSQL is production ready, Turso Database is not - although it is evolving rapidly.
