## What is MCP Firebird?
MCP Firebird is a server that implements Anthropic's [Model Context Protocol (MCP)](https://github.com/anthropics/anthropic-cookbook/tree/main/model_context_protocol) for [Firebird SQL databases](https://firebirdsql.org/). It allows Large Language Models (LLMs) like Claude to access, analyze, and manipulate data in Firebird databases securely and in a controlled manner.
## Key Features
- **SQL Queries**: Execute SQL queries on Firebird databases
- **Schema Analysis**: Get detailed information about tables, columns, and relationships
- **Database Management**: Perform backup, restore, and validation operations
- **Performance Analysis**: Analyze query performance and suggest optimizations
- **Multiple Transports**: Supports STDIO, SSE (Server-Sent Events), and Streamable HTTP transports
- **Modern Protocol Support**: Full support for MCP Streamable HTTP (2025-03-26) and legacy SSE
- **Unified Server**: Automatic protocol detection and backwards compatibility
- **Claude Integration**: Works seamlessly with Claude Desktop and other MCP clients
- **VSCode Integration**: Works with GitHub Copilot in Visual Studio Code
- **Session Management**: Robust session handling with automatic cleanup and configurable timeouts
- **Security**: Includes SQL query validation and security configuration options

## Basic Usage
### With Claude Desktop
1. Edit the Claude Desktop configuration:
```bash
code $env:AppData\Claude\claude_desktop_config.json # Windows
code ~/Library/Application\ Support/Claude/claude_desktop_config.json # macOS
```
2. Add the MCP Firebird configuration:
```json
{
"mcpServers": {
"mcp-firebird": {
"command": "npx",
"args": [
"mcp-firebird",
"--host",
"localhost",
"--port",
"3050",
"--database",
"C:\\path\\to\\database.fdb",
"--user",
"SYSDBA",
"--password",
"masterkey"
],
"type": "stdio"
}
}
}
```
3. Restart Claude Desktop
## Transport Configuration
MCP Firebird supports multiple transport protocols to accommodate different client needs and deployment scenarios.
### STDIO Transport (Default)
The STDIO transport is the standard method for Claude Desktop integration:
```json
{
"mcpServers": {
"mcp-firebird": {
"command": "npx",
"args": [
"mcp-firebird",
"--database", "C:\\path\\to\\database.fdb",
"--user", "SYSDBA",
"--password", "masterkey"
],
"type": "stdio"
}
}
}
```
### SSE Transport (Server-Sent Events)
SSE transport allows the server to run as a web service, useful for web applications and remote access:
#### Basic SSE Configuration
```bash
# Start SSE server on default port 3003
npx mcp-firebird --transport-type sse --database /path/to/database.fdb
# Custom port and full configuration
npx mcp-firebird \
--transport-type sse \
--sse-port 3003 \
--database /path/to/database.fdb \
--host localhost \
--port 3050 \
--user SYSDBA \
--password masterkey
```
#### Environment Variables for SSE
```bash
# Set environment variables
export TRANSPORT_TYPE=sse
export SSE_PORT=3003
export DB_HOST=localhost
export DB_PORT=3050
export DB_DATABASE=/path/to/database.fdb
export DB_USER=SYSDBA
export DB_PASSWORD=masterkey
# Start server
npx mcp-firebird
```
#### SSE Client Connection
Once the SSE server is running, clients can connect to:
- **SSE Endpoint**: `http://localhost:3003/sse`
- **Messages Endpoint**: `http://localhost:3003/messages`
- **Health Check**: `http://localhost:3003/health`
### Streamable HTTP Transport (Modern)
The latest MCP protocol supporting bidirectional communication:
```bash
# Start with Streamable HTTP
npx mcp-firebird --transport-type http --http-port 3003 --database /path/to/database.fdb
```
### Unified Transport (Recommended)
Supports both SSE and Streamable HTTP protocols simultaneously with automatic detection:
```bash
# Start unified server (supports both SSE and Streamable HTTP)
npx mcp-firebird --transport-type unified --http-port 3003 --database /path/to/database.fdb
```
#### Unified Server Endpoints
- **SSE (Legacy)**: `http://localhost:3003/sse`
- **Streamable HTTP (Modern)**: `http://localhost:3003/mcp`
- **Auto-Detection**: `http://localhost:3003/mcp-auto`
- **Health Check**: `http://localhost:3003/health`
### Configuration Examples
#### Development Setup (SSE)
```bash
npx mcp-firebird \
--transport-type sse \
--sse-port 3003 \
--database ./dev-database.fdb \
--user SYSDBA \
--password masterkey
```
#### Production Setup (Unified)
```bash
npx mcp-firebird \
--transport-type unified \
--http-port 3003 \
--database /var/lib/firebird/production.fdb \
--host db-server \
--port 3050 \
--user APP_USER \
--password $DB_PASSWORD
```
#### Docker with SSE
```bash
docker run -d \
--name mcp-firebird \
-p 3003:3003 \
-e TRANSPORT_TYPE=sse \
-e SSE_PORT=3003 \
-e DB_DATABASE=/data/database.fdb \
-v /path/to/database:/data \
purodelhi/mcp-firebird:latest
```
### Advanced SSE Configuration
#### Session Management
Configure session timeouts and limits:
```bash
# Environment variables for session management
export SSE_SESSION_TIMEOUT_MS=1800000 # 30 minutes
export MAX_SESSIONS=1000 # Maximum concurrent sessions
export SESSION_CLEANUP_INTERVAL_MS=60000 # Cleanup every minute
npx mcp-firebird --transport-type sse
```
#### CORS Configuration
For web applications, configure CORS settings:
```bash
# Allow specific origins
export CORS_ORIGIN="https://myapp.com,https://localhost:3000"
export CORS_METHODS="GET,POST,OPTIONS"
export CORS_HEADERS="Content-Type,mcp-session-id"
npx mcp-firebird --transport-type sse
```
#### SSL/TLS Support
For production deployments, use a reverse proxy like nginx:
```nginx
server {
listen 443 ssl;
server_name mcp-firebird.yourdomain.com;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;
location / {
proxy_pass http://localhost:3003;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
```
### Troubleshooting SSE
#### Common Issues
1. **Connection Refused**
```bash
# Check if server is running
curl http://localhost:3003/health
# Check port availability
netstat -an | grep 3003
```
2. **Session Timeout**
```bash
# Increase session timeout
export SSE_SESSION_TIMEOUT_MS=3600000 # 1 hour
```
3. **CORS Errors**
```bash
# Allow all origins (development only)
export CORS_ORIGIN="*"
```
4. **Memory Issues**
```bash
# Reduce max sessions
export MAX_SESSIONS=100
# Enable more frequent cleanup
export SESSION_CLEANUP_INTERVAL_MS=30000
```
5. **JSON Parsing Issues (Fixed in v2.3.0-alpha.1+)**
```bash
# If experiencing "Invalid message: [object Object]" errors,
# upgrade to the latest alpha version:
npm install mcp-firebird@alpha
# Or use the latest alpha directly:
npx mcp-firebird@alpha --transport-type sse
```
**Note**: Versions prior to 2.3.0-alpha.1 had a bug where POST requests to `/messages`
endpoint failed to parse JSON body correctly. This has been fixed with improved
middleware handling for both `application/json` and `text/plain` content types.
#### Monitoring and Logging
```bash
# Enable debug logging
export LOG_LEVEL=debug
# Monitor server health
curl http://localhost:3003/health | jq
# Check active sessions
curl http://localhost:3003/health | jq '.sessions'
```
