0nMCP
The world's largest interconnected MCP server. 1,640+ tools across 111 services.
The orchestrator behind every AI workflow we ship. 1,640+ tools across 111 services, available to any AI host that speaks MCP — Claude Desktop, Cursor, Windsurf, Cline, Continue, Gemini, custom. Open source, BSL 1.1 licensed, npm install away.
When Anthropic published the Model Context Protocol in 2024, every AI vendor scrambled to ship a half-built server. 0nMCP went the other way — we built the deepest one. Today it powers RocketOpp's entire service catalog, drives all the family sites, and is the single biggest reason we can offer enterprise-grade AI work at one-tenth the industry price.
How 0nMCP got built — and why.
We started building 0nMCP in late 2024 because every AI agent we shipped for clients needed the same dozen integrations — CRM, email, Slack, Stripe, GitHub, Google Workspace. Each one was a 2-week task. The math didn't work for small businesses.
Instead of charging the integration tax on every project, we paid it once. 0nMCP became the universal connector — every tool the team builds gets added to the catalog. Every project after gets it for free.
By Q2 2026 we'd crossed 1,000 tools across 50+ services. By May 2026 we hit 1,640+ / 96. We open-sourced the core under BSL 1.1 because the more developers extend it, the more leverage every RocketOpp client gets.
How agentic AI runs 0nMCP on autopilot.
0nMCP IS the orchestrator. Every other RocketOpp service ships on top of it.
When we build an AI agent for your CRM Automation engagement, that agent uses 0nMCP under the hood to call Stripe, send Slack messages, update HubSpot, run Groq inference, and write to Supabase — all from one MCP session.
When we ship an SXO engagement, the content engine uses 0nMCP to pull trending topics, generate articles via Groq, post to WordPress, fan out to LinkedIn, and notify the CRM — all observable in one dashboard.
It's not just leverage for us. It's leverage for any developer who builds on it. The same catalog that powers RocketOpp powers your stack the moment we plug you in.

Frequently asked questions
The honest answers a buyer would want before booking a call.
What is 0nMCP, exactly?
+
0nMCP is a Model Context Protocol server (npm: 0nmcp) that exposes 1,640+ tools across 111 services to any compliant AI host. It is currently the largest interconnected MCP server publicly available. Open-source under BSL 1.1.
Why does this matter for my business?
+
Every AI agent or assistant that speaks MCP can use the entire catalog through one connection. No custom integrations per tool, no per-vendor auth wiring. The same agent that runs in Claude Desktop on your laptop can run in your production app.
What kind of tools are in the catalog?
+
Anything you would touch in a real business: CRM, email, payments, ops, analytics, social, content, dev. Specifically: HubSpot, Salesforce, Stripe, Slack, GitHub, Google Workspace, Shopify, Twilio, Calendly, AWS, Vercel, Supabase, MongoDB — plus 80+ more.
How does authentication work?
+
Every credential lives in the 0nVault container — patent-pending AES-256-GCM + Argon2id encryption with full audit log and per-tool revocation. You hold the keys; we never see your tokens.
Is it really open source?
+
Yes. npm install 0nmcp, source on GitHub. BSL 1.1 license — usage-restricted only against direct commercial competition with us, otherwise open. You can fork it, self-host it, run it on-prem.
How do I get help integrating it?
+
For self-serve: full docs at 0nmcp.com. For done-for-you: book an MCP integration engagement with us — quoted per project, typically ships in a week.
