01 / SPECIFICATION & RUNTIME BEHAVIOR

How Model Context Protocol (MCP) Operates in Production

The Model Context Protocol (MCP) is an open specification pioneered by Anthropic that standardizes how AI applications connect to external tools, databases, and APIs. With an MCP server configured in your client (such as Claude Desktop or Cursor), your AI assistant can directly inspect database schemas, run SQL queries, search GitHub issues, and fetch web documentation safely.

Standard JSON ConfigurationSpec Syntax

Declare server executables and environment variables under the mcpServers key.

  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_your_token_here"
      }
    }
  }

04 / BEST PRACTICES
Never commit plaintext API tokens to public Git repositories; use environment variables where supported.
Scope filesystem servers strictly to the working project folder instead of root `/` or `C:\`.
Prefer read-only database credentials for development AI sessions.

05 / FREQUENTLY ASKED QUESTIONS

How do I install an MCP server in Claude Desktop?

Open Claude Desktop Settings > Developer > Edit Config. This opens `claude_desktop_config.json`. Paste the generated JSON block into the `mcpServers` object, save the file, and restart Claude Desktop.

Can I use MCP servers in Cursor or Windsurf?

Yes! Modern versions of Cursor and Windsurf support the Model Context Protocol. You can add the same stdio server configs in their respective MCP settings panels.
