MCP Configuration

This skill provides MCP server configuration templates, setup scripts, and environment management helpers for Claude Code MCP integration.

What This Skill Provides

1. Configuration Templates

• .mcp.json template for MCP server definitions
• Server configuration examples (FastMCP, Node.js, Python)
• API key management patterns

2. Setup Scripts

• setup-mcp-server.sh - Configure MCP server in .mcp.json
• validate-mcp-config.sh - Validate MCP configuration
• list-mcp-servers.sh - List available MCP servers

3. Server Type Templates

• stdio servers (local process)
• HTTP servers (remote API)
• SSE servers (server-sent events)

Instructions

Adding MCP Server Configuration

When user wants to configure MCP servers:

1. Check if .mcp.json exists in project
2. Use template to create/update configuration
3. Add server definition with type, command, args
4. Configure environment variables if needed

Example structure:

• mcpServers object
• Server name as key
• type: "stdio" or "http"
• command and args for stdio
• url for http servers

Validating Configuration

Execute validation script:

!{bash plugins/01-core/skills/mcp-configuration/scripts/validate-mcp-config.sh .mcp.json}

Checks for:

• Valid JSON format
• Required fields present
• Correct server type
• Valid command paths

Environment Setup

For MCP servers requiring API keys:

1. Create .env file (if not exists)
2. Add API key variables
3. Reference in MCP server config
4. Ensure .env is in .gitignore

Configuration Examples

FastMCP Server (stdio):

• type: stdio
• command: python
• args: ["-m", "server_name"]

HTTP Server:

• type: http
• url: https://api.example.com

With Environment Variables:

• env: { API_KEY: "${API_KEY}" }
• Reads from .env file

Success Criteria

• ✅ Valid .mcp.json configuration
• ✅ Server definitions are correct
• ✅ Environment variables configured
• ✅ API keys secured in .env
• ✅ Configuration validated
