Detailed Usage

generate_build_zig▶

Generate modern build.zig files with Zig 0.12+ patterns.

use_mcp_tool({
  server_name: "zig",
  tool_name: "generate_build_zig",
  arguments: {
    projectName: "my_zig_project",
    target: "native",
    dependencies: ["zlib", "sdl"]
  }
});

optimize_code▶

Optimize Zig code with modern Zig patterns and build mode analysis.

use_mcp_tool({
  server_name: "zig",
  tool_name: "optimize_code",
  arguments: {
    code: "const std = @import(\"std\");\n...",
    optimizationLevel: "ReleaseFast"
  }
});

estimate_compute_units▶

Estimates computational complexity and resource usage of Zig code.

use_mcp_tool({
  server_name: "zig",
  tool_name: "estimate_compute_units",
  arguments: {
    code: "const std = @import(\"std\");\n..."
  }
});

generate_code▶

Generates Zig code from natural language descriptions.

use_mcp_tool({
  server_name: "zig",
  tool_name: "generate_code",
  arguments: {
    prompt: "Create a function that sorts an array of integers",
    context: "Should handle empty arrays and use comptime when possible"
  }
});
