Core Capabilities:

Execute Go code - Run Go code in the Go Playground sandbox with optional go vet static analysis (enabled by default)
Share code snippets - Generate persistent, shareable Go Playground URLs
Execute and share simultaneously - Run code and get both execution results and a shareable URL in one operation
Read from URLs - Extract Go code from existing Go Playground URLs
Execute from URLs - Run Go code directly from existing Go Playground URLs
Multiple URL format support - Works with go.dev/play/, go.dev/play/p/, and play.golang.org/p/ URLs
MCP protocol compliance - Seamless integration with Model Context Protocol clients

🏃‍♂️ Usage

The server can be used with any MCP-compatible client. The server provides five tools:

run_go_code - Execute Go code and return results
share_go_code - Share Go code and get a URL
run_and_share_go_code - Execute code and get both results and share URL
read_go_playground_url - Read Go code from an existing Go Playground URL
execute_go_playground_url - Execute Go code from an existing Go Playground URL

Add this to your MCP client configuration:

{ "mcpServers": { "go-playground": { "command": "npx", "args": ["-y", "go-playground-mcp"] } } }

Examples

Reading code from a Go Playground URL

// Read code from https://go.dev/play/xyz123 const result = await mcpClient.callTool("read_go_playground_url", { url: "https://go.dev/play/xyz123" });

Executing code from a Go Playground URL

// Execute code from https://go.dev/play/xyz123 const result = await mcpClient.callTool("execute_go_playground_url", { url: "https://go.dev/play/xyz123", withVet: true });

URL Formats Supported

The new URL-based tools support these Go Playground URL formats:

https://go.dev/play/<snippet-id>
https://go.dev/play/p/<snippet-id>
https://play.golang.org/p/<snippet-id>
