The Model Context Protocol has become the connective tissue of the AI agent ecosystem — 97 million monthly SDK downloads, 52,000 servers in the official registry, nearly half of software companies running it in production. But there’s a problem nobody talks about enough: a 2026 analysis of 2,181 public MCP endpoints found that 52% are dead. The barrier isn’t interest. It’s infrastructure.
Hosting a production-ready MCP server means managing Docker containers, SSL certificates, auth flows, rate limiting, circuit breakers, and monitoring — before you’ve written a single line of business logic. Getting it enterprise-ready takes months. MCPCore launched to fix exactly that: a visual workflow builder, OpenAPI import, and fully managed cloud hosting that takes the path from idea to live MCP endpoint down from months to minutes.
Build MCP Tools Without Touching Infrastructure
MCPCore’s core offering is a drag-and-drop workflow canvas. You connect steps — HTTP Request, Database Query, Transform, Condition — and MCPCore handles everything behind it: the server runtime, HTTPS, auth, versioning, and hosting. There’s also a JavaScript escape hatch for developers who want full control over logic while still offloading ops.
The fastest path is OpenAPI import. Paste your OpenAPI 3 or Swagger 2 URL (or upload the file), select which endpoints you want to expose, and MCPCore turns each one into a typed MCP tool with parameters pre-filled and your API credentials stored as encrypted secrets. No configuration gymnastics. This matters because a huge share of the APIs developers want to surface as MCP tools already have OpenAPI specs — the conversion is mechanical, and MCPCore automates it.
If you don’t have an OpenAPI spec, describe what your tool should do in plain English and the platform’s AI assistant generates the workflow. It’s the kind of feature that sounds gimmicky but actually shortens the first draft significantly.
Security and Reliability Without the Setup Tax
The biggest fear with managed MCP hosting is security. MCPCore offers four access modes — Public, Unlisted, API Key, and OAuth 2.0 — with encrypted secret storage, traffic logging, and custom domain support built in. Every save creates a versioned snapshot you can compare or restore without an incident postmortem. The platform supports the MCP spec 2026-07-28, the latest revision that made the protocol stateless and significantly easier to scale.
Before deploying, there’s a playground where you can test your MCP server in real-time against Claude or GPT. This catches the broken tool calls that would otherwise hit production first.
Works With the Clients Your Team Already Uses
MCPCore servers work with Claude Code, Codex, Claude Desktop, Cursor, VS Code, Gemini CLI, Windsurf, and Cline. The connection config is a standard MCP endpoint URL — no SDK changes, no adapter layers. If your team already has Claude Code or Cursor in the workflow, an MCPCore server drops in without ceremony.
Pricing: The Free Tier Is Usable
| Plan | Price | Servers | Calls/Month |
|---|---|---|---|
| Free | $0 | 2 | 25K |
| Basic | $7.99/mo | 10 | 1M |
| Pro | $19.99/mo | 30 | 10M |
| Enterprise | Custom | Unlimited | Unlimited |
The free tier gives you 2 servers and 25,000 calls per month with no credit card required. That’s not a preview — it’s enough to build and ship a real tool for personal use or a small team. The Basic plan at $7.99/month adds 10 servers and 1 million calls per month, which covers most indie developer workloads.
For context: competing self-hosted options like Arcade, IBM ContextForge, or Amazon Bedrock AgentCore require infrastructure expertise, DevOps time, or AWS commitment. MCPCore’s free tier costs nothing and takes minutes. The tradeoff is trusting a managed platform with your endpoint — a reasonable call for most workloads.
The Bottom Line
MCPCore doesn’t do anything you couldn’t build yourself. That’s exactly the point. For most developers building MCP tools, the infrastructure fight is a distraction from what actually matters: getting tools into the hands of AI agents. MCP adoption is accelerating fast — 97M monthly downloads and counting — and there are developers who’ve been sitting on API integrations they want to surface as MCP tools but got stuck at the “now I need a hosted server” step. MCPCore removes that wall. Start with the free tier, see if the platform fits your workload, and graduate to paid when usage justifies it.
