Basic Usage

With Claude Desktop

Edit the Claude Desktop configuration:
code $env:AppData\Claude\claude_desktop_config.json # Windows code ~/Library/Application\ Support/Claude/claude_desktop_config.json # macOS
Add the MCP Firebird configuration:
{ "mcpServers": { "mcp-firebird": { "command": "npx", "args": [ "mcp-firebird", "--host", "localhost", "--port", "3050", "--database", "C:\\path\\to\\database.fdb", "--user", "SYSDBA", "--password", "masterkey" ], "type": "stdio" } } }
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:

{
  "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

# 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

# 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:

# 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:

# 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)

npx mcp-firebird \
  --transport-type sse \
  --sse-port 3003 \
  --database ./dev-database.fdb \
  --user SYSDBA \
  --password masterkey

Production Setup (Unified)

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

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:

# 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:

# 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:

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

Connection Refused
# Check if server is running curl http://localhost:3003/health # Check port availability netstat -an | grep 3003
Session Timeout
# Increase session timeout export SSE_SESSION_TIMEOUT_MS=3600000 # 1 hour
CORS Errors
# Allow all origins (development only) export CORS_ORIGIN="*"
Memory Issues
# Reduce max sessions export MAX_SESSIONS=100 # Enable more frequent cleanup export SESSION_CLEANUP_INTERVAL_MS=30000
JSON Parsing Issues (Fixed in v2.3.0-alpha.1+)
# 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

# 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'
