Open-Source Enterprise Model Context Protocol Servers

Building open-source Model Context Protocol (MCP) servers for enterprise tools. 16 servers live on the official registry, enabling AI agents to seamlessly integrate with critical business platforms.

No vendor lock-in. No enterprise agreements. Just open-source tools you can trust.

• ArgoCD - GitOps continuous delivery
• Rancher - Kubernetes management
• Azure - Microsoft cloud platform

• Harness - CI/CD platform
• Rundeck - Runbook automation
• UiPath - RPA automation

• ServiceNow - ITSM platform

• HubSpot - CRM and marketing automation
• Zoho CRM - Customer relationship management

• QuickBooks - Financial management
• FreshBooks - Accounting and invoicing
• Xero - Cloud accounting

• PowerBI - Business analytics
• Tableau - Data visualization

• Mailchimp - Email marketing
• Hootsuite - Social media management
• Chanty - Team communication

Some tools have official MCP implementations (Azure, ArgoCD, HubSpot). Many don't. These open-source alternatives give you:

• MIT Licensed - Audit the code, know what it does
• Free Forever - No licensing fees, no enterprise requirements
• Fully Customizable - Fork it, modify it, deploy your way
• Community Driven - Features based on real user needs

• Async/await throughout for high performance
• Retry logic with exponential backoff
• Rate limit handling
• Structured JSON logging
• Comprehensive error handling
• Environment-based configuration

# Install via uvx (recommended)
uvx servicenow-mcp-server
uvx argocd-mcp-server

Live on Registry: 16 servers ✅

• All production-ready
• All open source (MIT license)
• All installable via uvx or pip

Pending: 1 server ⏳

• HubSpot (awaiting PyPI README indexing)

Blocked: 2 servers ⚠️

• GCP, GitLab (PyPI ownership conflicts)

Every server follows a consistent architecture:

Stack:

• Python 3.8+
• MCP SDK
• Hatchling build system
• PyPI + uvx distribution

"Check if we have any critical ServiceNow incidents"
"Show me failed ArgoCD deployments in the last hour"
"Deploy staging branch to ArgoCD"

"List all Azure VMs in production"
"Create a P1 incident in ServiceNow for database outage"
"Run Rundeck job for production deployment"

"What's our revenue this quarter?" (QuickBooks)
"Show me unpaid invoices" (FreshBooks)
"List all active subscriptions" (Xero)

• Pull Requests: Contribute improvements
• MCP Registry: Find all published servers
• Documentation: Each repo has detailed README

Some tools have official MCP servers from vendors:

• Azure - Microsoft (GA)
• ArgoCD - argoproj-labs (Official)
• HubSpot - HubSpot (Beta)
• QuickBooks - Intuit (Preview, sandbox only)
• UiPath - Native platform support
• Rancher - SUSE (Tech Preview)

Why use community versions?

• Open source vs proprietary
• MIT license vs vendor agreements
• Free vs potential licensing costs
• Customizable vs vendor-controlled
• Community features vs vendor roadmap

Most tools (ServiceNow, Tableau, Zoho, PowerBI, etc.) have no official MCP servers - these community implementations fill that gap.

Accomplishment: 16 enterprise MCP servers published to official registry

Built during: Christmas/New Year holidays 2024-2025

Impact: Enterprise teams can now integrate AI with critical business tools using standardized, open-source MCP servers

Next: Continue adding servers as community needs them
