MCP Servers

By the end of this guide, you'll have a complete understanding of how to configure each MCP server in your ExzosSphere project, what tools they provide, and how to use them effectively with Lia and other code agents.

Overview

Model Context Protocol (MCP) servers extend your code agent's capabilities by providing specialized tools for different tasks. The ExzosSphere configures several key MCP servers that work seamlessly with ExzosAtom and your development workflow:

• ExzosAtom MCP: All these capabilities—development lifecycle management, code generation, API validation, documentation, code analysis, project management, knowledge base, task organization, and agent delegation—are provided as part of the ExzosAtom MCP server.
• Shadcn UI MCP: UI component scaffolding and design system integration
• Playwright MCP: Automated browser testing and interaction
• Postgres MCP: Database introspection and query operations

These servers are defined in your project's .mcp.json file and are automatically available to configured code agents like Lia.

Configuration File Structure

The .mcp.json file in your project root defines how each MCP server runs. Here's the complete configuration structure:

{
  "mcpServers": {
    "igniter": {
      "command": "npx",
      "args": ["-y", "@igniter-js/mcp-server@latest"],
      "env": {}
    },
    "browser": {
      "command": "npx",
      "args": ["@playwright/mcp@latest"],
      "env": {}
    },
    "shadcn": {
      "command": "npx",
      "args": ["shadcn@latest", "mcp"],
      "env": {}
    },
    "postgres": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://..."],
      "env": {
        "POSTGRES_CONNECTION_STRING": "postgresql://username:password@localhost:5432/database"
      }
    }
  }
}
