# MCP Server Demo Commands ## Command 1: Initialize the Server This sends an initialization request and shows the server's response: ```bash echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo-client","version":"1.0"}}}' | node dist/basic-mcp/server.js ``` **Expected Output:** - Server log: `Basic MCP Server running on stdio` - Response: JSON with server capabilities --- ## Command 2: List Available Tools ```bash (echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}'; sleep 0.1; echo '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}') | node dist/basic-mcp/server.js ``` **Expected Output:** - Shows list of available tools (hello, calculate) --- ## Command 3: Call the Hello Tool ```bash (echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}'; sleep 0.1; echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"hello","arguments":{"name":"Alice"}}}') | node dist/basic-mcp/server.js ``` **Expected Output:** - Response with: `"Hello, Alice! Welcome to MCP!"` --- ## Command 4: Call the Calculate Tool ```bash (echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}'; sleep 0.1; echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"calculate","arguments":{"operation":"multiply","a":15,"b":4}}}') | node dist/basic-mcp/server.js ``` **Expected Output:** - Response with: `"15 multiply 4 = 60"` --- ## Command 5: List Resources ```bash (echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}'; sleep 0.1; echo '{"jsonrpc":"2.0","id":2,"method":"resources/list","params":{}}') | node dist/basic-mcp/server.js ``` --- ## Command 6: Read a Resource ```bash (echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}'; sleep 0.1; echo '{"jsonrpc":"2.0","id":2,"method":"resources/read","params":{"uri":"demo://example"}}') | node dist/basic-mcp/server.js ``` --- ## Pretty Print JSON Responses To see formatted JSON output, pipe through `jq`: ```bash (echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}'; sleep 0.1; echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"hello","arguments":{"name":"Alice"}}}') | node dist/basic-mcp/server.js 2>/dev/null | jq . ``` --- ## Interactive Mode (Manual Testing) To manually send requests: 1. Start server in one terminal: ```bash node dist/basic-mcp/server.js ``` 2. In another terminal, send requests: ```bash echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"demo","version":"1.0"}}}' > /proc/$(pgrep -f "node dist/basic-mcp/server.js")/fd/0 ``` (Note: This is complex - better to use the piped commands above)
