Instructions

Adding MCP Server

1. Add Server Entry

   • Use script: scripts/add-mcp-server.sh <server-name> <command> <args...>
   • Updates .mcp.json with new server configuration

2. Configure Environment Variables

   • Use script: scripts/set-server-env.sh <server-name> <VAR=value>
   • Adds environment variables to server config

Managing Configuration

1. List Servers

   • Use script: scripts/list-mcp-servers.sh
   • Shows all configured MCP servers

2. Remove Server

   • Use script: scripts/remove-mcp-server.sh <server-name>
   • Removes server from configuration

3. Validate Config

   • Use script: scripts/validate-mcp-config.sh
   • Checks .mcp.json structure and server definitions
