What Exactly is an MCP Server?

Think of MCP servers as "APIs for AI." They let AI models like Claude interact with external tools in a standardized way.

AI Model (Claude)

Wants to check email, query a database, or post to Slack

MCP Server

External Service

Gmail, PostgreSQL, Stripe, GitHub, Notion, etc.

Standardized Protocol

One interface works with any MCP-compatible AI client. Build once, works everywhere.

Tool-Based Design

MCPs expose "tools" the AI can call. Like functions: send_email(), query_database(), create_issue().

Secure by Default

Credentials stay local. The AI requests actions, MCP executes them. No API keys sent to the cloud.

Why the MCP Opportunity is Now

The Gap in the Market

Thousands of developers are building MCPs. Thousands more want to use them. But there's no easy way to buy/sell—most MCPs are either open-source (no income for creators) or custom-built (expensive for buyers). We're fixing that.

How to Build an MCP Server

If you can build an API integration, you can build an MCP server. Here's the process:

  1. 1

    Choose Your Integration

    Pick an API or service you know well. Your expertise is your advantage. Popular choices: databases, SaaS tools, communication platforms.

  2. 2

    Define the Tools

    MCP servers expose 'tools' - functions the AI can call. Think about what actions users would want: read, write, search, update, delete.

  3. 3

    Handle Authentication

    Most integrations need auth. Support API keys, OAuth, or both. Make setup as simple as possible for buyers.

  4. 4

    Add Error Handling

    APIs fail. Rate limits hit. Credentials expire. Your MCP should handle these gracefully with clear error messages.

  5. 5

    Test with Claude

    Test your MCP with Claude Desktop. Verify tools work correctly, responses are useful, and edge cases are covered.

  6. 6

    Document Everything

    Setup instructions, tool descriptions, example prompts, troubleshooting guide. Good docs = happy buyers = fewer refunds.

Technical Resources

The official MCP specification and SDKs make building servers straightforward:

  • • modelcontextprotocol.io — Official docs
  • • Python and TypeScript SDKs available
  • • JSON-RPC based protocol (familiar if you've used LSP)

Pricing Your MCP Server

MCPs command higher prices than templates because they require more expertise and solve complex problems:

$20-40

Basic

  • Single service integration
  • Read-only operations
  • Simple authentication
  • Standard documentation

Examples: RSS feed reader, weather API, simple database viewer

$40-75

Standard

  • Full CRUD operations
  • OAuth support
  • Multiple tools exposed
  • Comprehensive docs + examples

Examples: Notion manager, GitHub integration, email client

$75-150

Professional

  • Complex API integration
  • Multi-account support
  • Advanced error handling
  • Video walkthrough

Examples: Stripe billing suite, Salesforce connector, AWS manager

$150+

Enterprise

  • Multi-service bundles
  • Custom deployment options
  • Priority support included
  • Industry-specific solutions

Examples: Complete DevOps toolkit, E-commerce stack, Analytics suite

MCP Best Practices

Clear Tool Descriptions
The AI reads your tool descriptions to decide when to use them. Be specific: "Send a message to a Slack channel" beats "Slack integration."
Secure Credential Handling
Support environment variables and config files. Never hardcode credentials. Document where and how to store API keys.
Meaningful Responses
Return structured, useful data. If querying a database, format results clearly. The AI will use your response to answer the user.
Easy Installation
Provide clear installation steps. Support npm/pip install where possible. The easier setup is, the better reviews you'll get.
