# Connect to stream
curl -N -H "Accept: text/event-stream" http://localhost:3000/mcp/stream

STDIO Transport

Process-based communication:

echo '{"jsonrpc":"2.0","id":1,"method":"initialize"}' | \
docker run --rm -i \
  -e TRANSPORT=stdio \

# Or set in .env file:
# HOST_PORT=8080
# CONTAINER_PORT=3000

🔧 Session Management

The server provides advanced session management for HTTP requests to maintain state across multiple API calls:

Session Creation

Sessions are automatically created on the first request and tracked via:

X-Session-ID Header: Primary method for API clients
mcp-session Cookie: Browser-friendly session persistence
Request Body Parameter: Alternative session identification

Session Persistence Examples

Using Headers (Recommended for API clients):

# 1. Initialize and get session ID
response=$(curl -s -i -X POST http://localhost:3000/mcp/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {...}}')

# Extract session ID from X-Session-ID header
session_id=$(echo "$response" | grep -i "x-session-id" | cut -d' ' -f2 | tr -d '\r')

# 2. Use session ID in subsequent requests
curl -X POST http://localhost:3000/mcp/ \
  -H "Content-Type: application/json" \
  -H "X-Session-ID: $session_id" \
  -d '{"jsonrpc": "2.0", "id": 2, "method": "tools/list", "params": {}}'

Using Authorization Bearer (Alternative method):

# Use session ID as Bearer token
curl -X POST http://localhost:3000/mcp/ \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $session_id" \
  -d '{"jsonrpc": "2.0", "id": 3, "method": "resources/list", "params": {}}'

Using Cookies (Browser-compatible):

# Save cookies and reuse them
curl -c cookies.txt -X POST http://localhost:3000/mcp/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {...}}'

# Subsequent requests with cookies
curl -b cookies.txt -X POST http://localhost:3000/mcp/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 2, "method": "resources/list", "params": {}}'

Session Features

Automatic Creation: Sessions created transparently on first request
Multiple Persistence Methods: Headers, cookies, and body parameters
aiohttp.ClientSession Compatible: Optimized for Python HTTP clients
Authorization Bearer Support: Alternative session identification method
Configurable Timeout: Sessions expire after SESSION_TIMEOUT seconds
Reconnection Support: SSE transport allows session reconnection
Rate Limiting: Per-session rate limits for tools and resources
Security: SameSite protection, configurable secure flag for HTTPS
