Why I'm betting on MCP servers as the next developer tools category

#ai #mcp #startup #programming

MCP servers are going to be as important to AI-native development as npm packages are to JavaScript development. Here's why I'm building my business on them.

What MCP actually changes

Before MCP, every AI integration was custom. Want Claude to read your database? Write a custom tool. Want it to call the Stripe API? Write another custom tool. Want it to search your codebase? Another custom tool. Each one is bespoke, project-specific, and non-reusable.

MCP standardizes the interface between AI models and external tools. One protocol. Any tool. Any AI host.

Before MCP:
  Claude Desktop → custom code → your database
  Claude Code → different custom code → your database  
  Your app → yet another implementation → your database

After MCP:
  Claude Desktop ─┐
  Claude Code    ──┼── MCP protocol ── your-db-server ── your database
  Your app       ─┘
Enter fullscreen mode Exit fullscreen mode

Write the MCP server once. It works everywhere Claude runs.

Why this is a category, not a feature

npm packages became a category because they solved a universal problem: code reuse across projects. Before npm, every JavaScript project re-implemented its own HTTP client, date formatter, and validation library.

MCP servers solve the same problem for AI tool integration. Before MCP, every project re-implements its own "let the AI access my database" code. After MCP, you npm install @your-org/db-mcp and it works.

The economics are identical:

  • Open-source MCP servers = free, community-maintained, general purpose
  • Premium MCP servers = paid, professionally maintained, specialized domains
  • Custom MCP servers = built in-house for proprietary data/systems

This is the npm ecosystem model applied to AI tooling.

The market right now

MCP was released by Anthropic in late 2024. In early 2026, the ecosystem is still nascent:

  • ~500 open-source MCP servers on GitHub
  • ~20 companies selling premium MCP servers
  • Claude Desktop and Claude Code have native MCP support
  • VS Code extensions are adding MCP host capabilities
  • Cursor has announced MCP support

We're at the "2013 npm" stage: the protocol exists, early adopters are building, but mainstream adoption hasn't happened yet. The developers building MCP servers now are the ones who'll own the category when it goes mainstream.

What makes a good MCP server business

The best MCP server businesses have three properties:

1. Domain expertise the AI doesn't have

Claude knows JavaScript syntax. It doesn't know your company's internal API, your industry's compliance requirements, or real-time market data. MCP servers that bridge this gap between "what the AI knows" and "what the AI needs to know" are the most valuable.

My Crypto Data MCP works because Claude can reason about financial data brilliantly — it just doesn't have any. Give it real-time prices and OHLCV data, and suddenly it can do analysis that would take a human analyst hours.

2. Data that changes

Static information eventually gets absorbed into training data. Real-time, dynamic data never will. MCP servers that provide live data — market prices, monitoring metrics, deployment status, CI/CD results — have a permanent moat.

3. Actions the AI can take safely

The most powerful MCP servers don't just read data — they take actions. A Stripe MCP that can create invoices. A GitHub MCP that can create PRs. A Slack MCP that can post messages. These save real time by letting the AI complete tasks end-to-end.

The safety boundary is critical: read-only servers are easy to trust. Write-capable servers need careful permission design.

What I'm building

Whoff Agents sells four MCP servers:

  • MCP Security Scanner ($29) — scans any MCP server for 22 vulnerability categories
  • Crypto Data MCP ($29/mo) — real-time market data, technical indicators, portfolio analysis
  • Workflow Automator MCP — chains multiple tools into automated workflows
  • Trading Signals MCP — options flow, institutional movements, sentiment analysis

Each one provides something the AI can't do alone: real-time data, security analysis of external code, and multi-step workflow execution.

The developer tools parallel

Every major developer tools category followed the same pattern:

  1. Protocol emerges (HTTP, npm, Docker, GraphQL, MCP)
  2. Early builders create implementations (Express, lodash, Docker Hub, Apollo, us)
  3. Ecosystem grows (thousands of packages, images, schemas, servers)
  4. Businesses form around quality and specialization (Vercel, Datadog, Hasura, ?)
  5. The protocol becomes infrastructure (you don't think about HTTP anymore)

MCP is at stage 2-3. The businesses being built now will either become the category leaders or get absorbed by them.

The bet

I'm betting that in 2 years:

  • Every IDE will be an MCP host
  • Every SaaS product will offer an MCP server alongside its REST API
  • MCP servers will be as discoverable and installable as npm packages
  • The companies that built the best MCP servers early will own significant developer mindshare

This bet could be wrong. MCP could get replaced by a competing protocol. OpenAI could ship something incompatible. The ecosystem could fragment.

But the underlying trend — AI needs structured access to external tools and data — is not going away. MCP is the best implementation of that idea right now. I'd rather build on it and be early than wait for certainty and be late.

If you're a developer who knows a domain well, building an MCP server for that domain is one of the highest-leverage things you can do in 2026. The protocol is simple, the demand is growing, and the market is wide open.
