Questions

How do I install Db?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Db need an API key?

No required environment variable is listed on this record.

What transport does Db use?

Db runs locally over stdio.

Documentation

DB MCP Server

A Rust-based MCP server that enables AI assistants to interact with SQL databases (SQLite, PostgreSQL, MySQL) safely and efficiently.

Features

Multi-database support: SQLite, PostgreSQL, MySQL
Read-only by default: Write operations require explicit ?writable=true flag
Transaction support: Full ACID transaction management across multiple MCP calls
Two transport modes:
- stdio for CLI integration (Claude Desktop, etc.)
- HTTP with Server-Sent Events for web clients
HTTP authentication: Bearer token authentication for HTTP transport (MCP 2025-03-26 spec)
Parameterized queries: Built-in SQL injection protection
Server-level connections: Connect to database server without selecting a database
Dangerous operation guard: AST-based protection against DROP, TRUNCATE, and unqualified DELETE/UPDATE
Lazy per-database pools: Efficient connection pooling for server-level connections
Dynamic connection management: Add, update, or remove database connections at runtime
Output formatting: JSON, ASCII table, or Markdown table formats

Installation

cargo install --path .

Or build from source:

cargo build --release

Usage

Single Database

# SQLite (read-only)
db-mcp-server --database sqlite:data.db

# SQLite (writable)
db-mcp-server --database sqlite:data.db?writable=true

# PostgreSQL (specific database)
db-mcp-server --database postgres://user:pass@localhost/mydb

# PostgreSQL (server-level, no default database)
db-mcp-server --database postgres://user:pass@localhost:5432?writable=true

# MySQL with write access
db-mcp-server --database mysql://user:pass@localhost/mydb?writable=true

Multiple Databases

Configure multiple databases using one of these methods:

Method 1: Command Line (repeat -d flag)

# Use auto-generated IDs (derived from database name)
db-mcp-server -d sqlite:one.db -d postgres://localhost/two

# Use custom IDs (recommended)
db-mcp-server -d app=sqlite:app.db?writable=true -d analytics=postgres://user:pass@localhost/analytics

# Mix multiple databases
db-mcp-server \
  -d main=sqlite:main.db?writable=true \
  -d reports=mysql://user:pass@localhost/reports \
  -d logs=postgres://user:pass@localhost/logs?writable=true

Method 2: Environment Variable (comma-separated)

# Single database
export MCP_DATABASE="sqlite:data.db?writable=true"
db-mcp-server

# Multiple databases
export MCP_DATABASE="\
app=sqlite:app.db?writable=true,\
analytics=postgres://user:pass@localhost/analytics,\
logs=mysql://user:pass@localhost/logs?writable=true"
db-mcp-server

Method 3: Claude Desktop Configuration

See Claude Desktop Configuration section below.

Connection String Format

# SQLite
sqlite:path/to/db.db
sqlite:path/to/db.db?writable=true

# PostgreSQL
postgres://user:pass@host:port/database
postgres://user:pass@host:5432                    # server-level
postgres://user:pass@host/database?writable=true

# MySQL
mysql://user:pass@host:port/database
mysql://user:pass@host:3306                       # server-level
mysql://user:pass@host/database?writable=true

# Named connections (recommended for multiple databases)
id=<connection_string>
app=sqlite:app.db?writable=true
analytics=postgres://user:pass@localhost/analytics

HTTP Mode

# HTTP mode (with SSE)
db-mcp-server --transport http --database sqlite:data.db

# HTTP mode with custom host/port
db-mcp-server --transport http --database sqlite:data.db --http-host 0.0.0.0 --http-port 3000

Authentication (HTTP Mode)

HTTP transport supports Bearer token authentication. STDIO transport does not require authentication as it relies on OS-level process isolation.

Enable authentication:

# Single token via CLI
db-mcp-server --transport http --database sqlite:data.db --auth-token my-secret-token

# Multiple tokens via CLI
db-mcp-server --transport http --database sqlite:data.db \
  --auth-token token1 --auth-token token2

# Via environment variable (comma-separated)
export MCP_AUTH_TOKENS="token1,token2,token3"
db-mcp-server --transport http --database sqlite:data.db

Client usage:

Include the token in the Authorization header:

Authorization: Bearer my-secret-token

MCP Tools

Read-Only Tools

Tool	Description
`list_connections`	List available database connections with type and read-only status
`query`	Execute SELECT queries with optional output formatting (json/table/markdown)
`list_tables`	List tables and views in a database
`describe_table`	Get detailed table schema (columns, primary keys, foreign keys, indexes)
`list_databases`	List all databases on server (MySQL/PostgreSQL only)
`explain`	Show query execution plan without executing

Write Tools (require `?writable=true` in connection string)

Tool	Description
`execute`	Execute INSERT/UPDATE/DELETE/DDL statements
`begin_transaction`	Start a new transaction (returns transaction_id)
