Requires Node 18+ on your system so npx can fetch the package on first run. Claude Desktop only speaks stdio locally; HTTP servers are wrapped via npx mcp-remote automatically. Paste the config below, then follow the reload step to register @mastra/mcp-registry-registry.
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json~/.config/Claude/claude_desktop_config.json{
"mcpServers": {
"mastramcp-registry-registry": {
"command": "npx",
"args": [
"-y",
"@mastra/mcp-registry-registry"
