šŸš€ Quick Start

Prerequisites

  • Docker installed on your system

  • HubSpot Private App Access Token (Setup Guide)

1. Run Container

GitHub Container Registry (Recommended):

docker run -d \ --name hubspot-mcp-server \ -p 3000:3000 \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token_here \ -e TRANSPORT=http \ --restart unless-stopped \ ghcr.io/sanketskasar/hubspot-mcp-server:latest

Docker Hub:

docker run -d \ --name hubspot-mcp-server \ -p 3000:3000 \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token_here \ -e TRANSPORT=http \ --restart unless-stopped \ sanketskasar/hubspot-mcp-server:latest

Custom Port Configuration:

# Use custom host port (e.g., 8080) while keeping container port as 3000 docker run -d \ --name hubspot-mcp-server \ -p 8080:3000 \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token_here \ --restart unless-stopped \ ghcr.io/sanketskasar/hubspot-mcp-server:latest # Use custom container port (requires rebuild) docker build --build-arg EXPOSE_PORT=8080 -t hubspot-mcp-server:custom . docker run -d \ --name hubspot-mcp-server \ -p 8080:8080 \ -e PORT=8080 \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token_here \ hubspot-mcp-server:custom

2. Verify Installation

# Check health curl http://localhost:3000/health # Expected response: # {"status":"healthy","uptime":...,"version":"1.0.0","sessions":0} # Check MCP capabilities curl -X POST http://localhost:3000/mcp/ \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"clientInfo":{"name":"test"}}}'

šŸ”§ Transport Protocols

HTTP Transport (Default)

Standard JSON-RPC 2.0 over HTTP:

docker run -d -p 3000:3000 \ -e TRANSPORT=http \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token \ ghcr.io/sanketskasar/hubspot-mcp-server:latest

Streamable HTTP Transport

Server-sent events for real-time updates:

docker run -d -p 3000:3000 \ -e TRANSPORT=streamable-http \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token \ ghcr.io/sanketskasar/hubspot-mcp-server:latest # 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 \ -e HUBSPOT_PRIVATE_APP_ACCESS_TOKEN=your_token \ ghcr.io/sanketskasar/hubspot-mcp-server:latest

āš™ļø Configuration

Docker Compose

Basic Configuration:

version: '3.8' services: hubspot-mcp-server: image: ghcr.io/sanketskasar/hubspot-mcp-server:latest container_name: hubspot-mcp-server ports: - "${HOST_PORT:-3000}:${CONTAINER_PORT:-3000}" environment: HUBSPOT_PRIVATE_APP_ACCESS_TOKEN: ${HUBSPOT_PRIVATE_APP_ACCESS_TOKEN} PORT: ${CONTAINER_PORT:-3000} TRANSPORT: http MAX_CONNECTIONS: 100 SESSION_TIMEOUT: 3600 RATE_LIMIT_TOOLS: 60 RATE_LIMIT_RESOURCES: 30 LOG_LEVEL: info restart: unless-stopped healthcheck: test: ["CMD", "curl", "-f", "http://localhost:${CONTAINER_PORT:-3000}/health"] interval: 30s timeout: 10s retries: 3

Custom Port Configuration:

# Run on custom ports HOST_PORT=8080 CONTAINER_PORT=3000 docker-compose up -d # Or set in .env file: # HOST_PORT=8080 # CONTAINER_PORT=3000

šŸ”§ 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
