An in-process SQL database, compatible with SQLite.

---

About

Turso Database is an in-process SQL database written in Rust, compatible with SQLite.

⚠️ Warning: This software is in BETA. 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 for details]
* Change data capture (CDC) for real-time tracking of database changes.
* Multi-language support for
* Go
* JavaScript
* Java
* .NET
* Python
* Rust
* WebAssembly
* 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 maintenance and query subscriptions.
* Full-Text-Search powered by the awesome tantivy library

The following features are on our current roadmap:

* Vector indexing for fast approximate vector search, similar to libSQL vector search.

Getting Started

Please see the Turso Database Manual for more information.

<details>
<summary>🤖 MCP Server Mode</summary>

The Turso CLI includes a built-in Model Context Protocol (MCP) 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, 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:

<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

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
from the ground up, and is also tested by Antithesis.

Even during Beta, 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.

List of rewarded cases:

* B-Tree interior cell replacement issue in btrees with depth >=3 (#2106)
* Don't allow autovacuum to be flipped on non-empty databases (#3830)
* Self-insert with nested subquery generates corrupt data (#3436)
* Ptrmap data corruption with pre-initialized autovacuum database (#3894)
* WAL corruption on statement rollback with constraint violation (#4493)

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. More details here.
