\n\n---\n\n## About\n\nTurso is an in-process SQL database written in Rust, compatible with SQLite. It runs in production today at multiple organizations.\n\nTurso is also a virtual machine. Like SQLite, it compiles SQL into bytecode for that machine, the VDBE, and then runs the bytecode. That design is what lets one engine host more than one SQL dialect. SQLite is the first and primary frontend that compiles to it, and Postgres is now a frontend of its own, with its own dialect and wire protocol. More will follow. Our goal is to be for databases what LLVM is to compilers, with one modern and reliable core, and many frontends compiled down onto it.\n\nHow general is that core? General enough to [run Doom](https://github.com/tursodatabase/turso-vdbe-doom-example) on it.\n\nSee the [FAQ](#faq) for where the project stands on its way to 1.0.\n\n## Features and Roadmap\n\n* **SQLite compatibility** for SQL dialect, file formats, and the C API, tracking SQLite version 3.50.4 [see [document](COMPAT.md) for details]\n* **`BEGIN CONCURRENT`** for improved write throughput using multi-version concurrency control (MVCC).\n* **Change data capture (CDC)** for real-time tracking of database changes.\n* **Multi-language support** for\n * [Go](bindings/go)\n * [JavaScript](bindings/javascript)\n * [Java](bindings/java)\n * [.NET](bindings/dotnet)\n * [Python](bindings/python)\n * [Rust](bindings/rust)\n * [WebAssembly](bindings/javascript)\n* **Asynchronous I/O** support on Linux with `io_uring`\n* **Cross-platform** support for Linux, macOS, Windows and browsers (through WebAssembly)\n* **Vector support** support including exact search and vector manipulation\n* **Improved schema management** including extended `ALTER` support and faster schema changes.\n\nThe database has the following experimental features:\n\n* **Postgres compatibility** for SQL dialect and wire protocol, see the see [compatibility reference](postgres/COMPAT.md) for details.\n* **Encryption at rest** for protecting the data locally.\n* **Incremental computation** using DBSP for incremental view maintenance and query subscriptions.\n* **Full-Text-Search** powered by the awesome [tantivy](https://github.com/quickwit-oss/tantivy) library\n* **Multi-process WAL coordination** via the `.tshm` sidecar for cross-process WAL readers and writers.\n\nThe following features are on our current roadmap:\n\n* **Vector indexing** for fast approximate vector search, similar to [libSQL vector search](https://turso.tech/vector).\n\n## Getting Started\n\nPlease see the [Turso Database Manual](docs/manual.md) for more information.\n\n

\n\n
\n🤖 MCP Server Mode\n
\n\n\nThe Turso CLI includes a built-in [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that allows AI assistants to interact with your databases.\n\nStart the MCP server with:\n\n```shell\ntursodb your_database.db --mcp\n```\n\n### Configuration\n\nAdd Turso to your MCP client configuration:\n\n```json\n{\n \"mcpServers\": {\n \"turso\": {\n \"command\": \"/path/to/.turso/tursodb\",\n \"args\": [\"/path/to/your/database.db\", \"--mcp\"]\n }\n }\n}\n```\n\n### Available Tools\n\nThe MCP server provides nine tools for database interaction:\n\n1. **`open_database`** - Open a new database\n2. **`current_database`** - Describe the current database\n3. **`list_tables`** - List all tables in the database\n4. **`describe_table`** - Describe the structure of a specific table\n5. **`execute_query`** - Execute read-only SELECT queries\n6. **`insert_data`** - Insert new data into tables\n7. **`update_data`** - Update existing data in tables\n8. **`delete_data`** - Delete data from tables\n9. **`schema_change`** - Execute schema modification statements (CREATE TABLE, ALTER TABLE, DROP TABLE)\n\nOnce connected, you can ask your AI assistant:\n\n- \"Show me all tables in the database\"\n- \"What's the schema for the users table?\"\n- \"Find all posts with more than 100 upvotes\"\n- \"Insert a new user with name 'Alice' and email 'alice@example.com'\"\n\n### MCP Clients\n\n
\nClaude Code\n\nIf 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:\n\n#### Quick Setup\n\n1. **Add the MCP server** to Claude Code:\n\n ```bash\n claude mcp add my-database -- tursodb ./path/to/your/database.db --mcp\n ```\n\n2. **Restart Claude Code** to activate the connection\n\n3. **Start querying** your database through natural language!\n\n#### Command Breakdown\n\n```bash\nclaude mcp add my-database -- tursodb ./path/to/your/database.db --mcp\n# ↑ ↑ ↑ ↑\n# | | | |\n# Name | Database path MCP flag\n# Separator\n```\n\n- **`my-database`** - Choose any name for your MCP server\n- **`--`** - Required separator between Claude options and your command\n- **`tursodb`** - The Turso database CLI\n- **`./path/to/your/database.db`** - Path to your SQLite database file\n- **`--mcp`** - Enables MCP server mode\n\n#### Example Usage\n\n```bash\n# For a local project database\ncd /your/project\nclaude mcp add my-project-db -- tursodb ./data/app.db --mcp\n\n# For an absolute path\nclaude mcp add analytics-db -- tursodb /Users/you/databases/analytics.db --mcp\n\n# For a specific project (local scope)\nclaude mcp add project-db --local -- tursodb ./database.db --mcp\n```\n\n#### Managing MCP Servers\n\n```bash\n# List all configured MCP servers\nclaude mcp list\n\n# Get details about a specific server\nclaude mcp get my-database\n\n# Remove an MCP server\nclaude mcp remove my-database\n```\n\n
\n\n
\nClaude Desktop\n\nFor Claude Desktop, add the configuration to your `claude_desktop_config.json` file:\n\n```json\n{\n \"mcpServers\": {\n \"turso\": {\n \"command\": \"/path/to/.turso/tursodb\",\n \"args\": [\"./path/to/your/database.db\", \"--mcp\"]\n }\n }\n}\n```\n\n
\n\n
\nCursor\n\nFor Cursor, configure MCP in your settings:\n\n1. Open Cursor settings\n2. Navigate to Extensions → MCP\n3. Add a new server with:\n - **Name**: `turso`\n - **Command**: `/path/to/.turso/tursodb`\n - **Args**: `[\"./path/to/your/database.db\", \"--mcp\"]`\n\nAlternatively, you can add it to your Cursor configuration file directly.\n\n
\n\n### Direct JSON-RPC Usage\n\nThe MCP server runs as a single process that handles multiple JSON-RPC requests over stdin/stdout. Here's how to interact with it directly:\n\n#### Example with In-Memory Database\n\n```bash\ncat << 'EOF' | tursodb --mcp\n{\"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"initialize\", \"params\": {\"protocolVersion\": \"2024-11-05\", \"capabilities\": {}, \"clientInfo\": {\"name\": \"client\", \"version\": \"1.0\"}}}\n{\"jsonrpc\": \"2.0\", \"id\": 2, \"method\": \"tools/call\", \"params\": {\"name\": \"schema_change\", \"arguments\": {\"query\": \"CREATE TABLE users (id INTEGER, name TEXT, email TEXT)\"}}}\n{\"jsonrpc\": \"2.0\", \"id\": 3, \"method\": \"tools/call\", \"params\": {\"name\": \"list_tables\", \"arguments\": {}}}\n{\"jsonrpc\": \"2.0\", \"id\": 4, \"method\": \"tools/call\", \"params\": {\"name\": \"insert_data\", \"arguments\": {\"query\": \"INSERT INTO users VALUES (1, 'Alice', 'alice@example.com')\"}}}\n{\"jsonrpc\": \"2.0\", \"id\": 5, \"method\": \"tools/call\", \"params\": {\"name\": \"execute_query\", \"arguments\": {\"query\": \"SELECT * FROM users\"}}}\nEOF\n```\n\n#### Example with Existing Database\n\n```bash\n# Working with an existing database file\ncat << 'EOF' | tursodb mydb.db --mcp\n{\"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"initialize\", \"params\": {\"protocolVersion\": \"2024-11-05\", \"capabilities\": {}, \"clientInfo\": {\"name\": \"client\", \"version\": \"1.0\"}}}\n{\"jsonrpc\": \"2.0\", \"id\": 2, \"method\": \"tools/call\", \"params\": {\"name\": \"list_tables\", \"arguments\": {}}}\nEOF\n```\n\n

Please check out the [contribution guide] to get started.\n\n## FAQ\n\n### Is Turso Database ready for production use?\n\nYes — Turso powers production applications today at multiple organizations, including [Turso Cloud](https://turso.tech/signup), the [Kin AI assistant](https://mykin.ai/), and [Spice.ai](https://github.com/spiceai/spiceai). Reliability is our top priority: Turso is extensively tested by a collection of tools including a native Deterministic Simulation Testing suite and [Antithesis](https://antithesis.com).\n\nThat said, we have not yet reached 1.0. The project is under active development, and some features are explicitly marked experimental. Our bar is SQLite-level reliability — one of the most rigorously tested pieces of software in the world — and until we declare 1.0, we recommend the same discipline you would apply to any database: keep independent backups.\n\n### How compatible is Turso Database with SQLite?\n\nTurso is compatible with SQLite at the SQL dialect, file format, and C API levels, and existing SQLite database files work as-is. We are not at 100% yet, so some differences are still expected — [COMPAT.md](COMPAT.md) tracks the details — but the gap is closing quickly, and full compatibility is a requirement for 1.0.\n\n### Is Turso a SQLite database or a Postgres database?\n\nIt is one engine with more than one SQL frontend. SQLite is the original and primary frontend, with its dialect, its file format, and its C API, and if that is what you use, nothing changes for you. Postgres is a newer and still experimental frontend that speaks the Postgres dialect and wire protocol. They share everything below the SQL: the storage, the concurrency, the query compiler, and the VM. Postgres is additive.\n\n### What do you mean by \"the LLVM of databases\"?\n\nLike SQLite, Turso compiles a query into bytecode for a virtual machine called the VDBE, and runs that bytecode. SQL is just one language that compiles to it. Our goal is to make that VM a general target, with one modern and rigorously tested core, and many database frontends compiled onto it: SQLite, Postgres, and others over time. LLVM did this for compilers, where a stable intermediate representation let many languages share one backend, and we think databases deserve the same. The bytecode is general enough to [run Doom](https://github.com/tursodatabase/turso-vdbe-doom-example), if you want proof.\n\n### How is Turso Database different from Turso's libSQL?\n\nTurso 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.\n\nRewriting SQLite in Rust started as an unassuming experiment, and due to its incredible success, replaces libSQL as our intended direction. Both run in production today: libSQL has been battle-tested for longer, while Turso Database is where our development effort is focused and is evolving rapidly.
