Zig MCP Server

Modern Zig AI 10x dev assistant with comprehensive build system support

A powerful Model Context Protocol (MCP) server that provides comprehensive Zig language assistance, including modern build system support, code optimization, and best practices guidance.

🚀 What's New in v0.2.0

  • 🏗️ Modern Build System Support: Generate and analyze build.zig files with Zig 0.12+ patterns

  • 📦 Dependency Management: Create build.zig.zon files for modern package management

  • 🔧 Enhanced Code Analysis: Improved optimization suggestions and pattern detection

  • 🧪 Comprehensive Testing: 85+ test cases with full coverage reporting

  • ⚡ Better Performance: Modular architecture with improved error handling

  • 📚 Extended Documentation: Build system troubleshooting and best practices guides

🛠️ Features

🏗️ Build System Tools (NEW!)

1. Build System Generation (generate_build_zig)

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

  • Cross-compilation support

  • Modern dependency management

  • Test and documentation integration

2. Build System Analysis (analyze_build_zig)

Analyze existing build files and get modernization recommendations:

  • Detect deprecated patterns

  • Suggest Zig 0.12+ alternatives

  • Identify missing best practices

3. Dependency Management (generate_build_zon)

Generate build.zig.zon files for modern package management:

  • Popular Zig packages catalog

  • Version management guidance

  • Best practices documentation

Features

Tools

1. Code Optimization (optimize_code)

Enhanced with modern Zig patterns and build mode analysis:

  • Debug, ReleaseSafe, ReleaseFast, ReleaseSmall

  • Modern optimization suggestions

  • Zig 0.12+ pattern recommendations

// Example usage { "code": "const std = @import(\"std\");\n...", "optimizationLevel": "ReleaseFast" }

2. Compute Units Estimation (estimate_compute_units)

Estimates computational complexity and resource usage of Zig code:

  • Memory usage analysis

  • Time complexity estimation

  • Allocation patterns detection

// Example usage { "code": "const std = @import(\"std\");\n..." }

3. Code Generation (generate_code)

Generates Zig code from natural language descriptions with support for:

  • Error handling

  • Testing

  • Performance optimizations

  • Documentation

// Example usage { "prompt": "Create a function that sorts an array of integers", "context": "Should handle empty arrays and use comptime when possible" }

4. Code Recommendations (get_recommendations)

Provides code improvement recommendations and best practices:

  • Style and conventions

  • Design patterns

  • Safety considerations

  • Performance insights

// Example usage { "code": "const std = @import(\"std\");\n...", "prompt": "Improve performance and safety" }

Resources

  1. Language Reference (zig://docs/language-reference)

    • Official Zig language documentation

    • Syntax and features guide

    • Best practices

  2. Standard Library Documentation (zig://docs/std-lib)

    • Complete std library reference

    • Function signatures and usage

    • Examples and notes

  3. Popular Repositories (zig://repos/popular)

    • Top Zig projects on GitHub

    • Community examples and patterns

    • Real-world implementations

Installation

Installing via Smithery

To install Zig MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install zig-mcp-server --client claude

Manual Installation

  1. Clone the repository:

git clone [repository-url] cd zig-mcp-server

  1. Install dependencies:

npm install

  1. Build the server:

npm run build

  1. Configure environment variables:

# Create a GitHub token for better API rate limits # https://github.com/settings/tokens # Required scope: public_repo GITHUB_TOKEN=your_token_here

  1. Add to MCP settings:

{ "mcpServers": { "zig": { "command": "node", "args": ["/path/to/zig-mcp-server/build/index.js"], "env": { "GITHUB_TOKEN": "your_token_here", "NODE_OPTIONS": "--experimental-vm-modules" }, "restart": true } } }

Usage Examples

1. Optimize Code

const result = await useMcpTool("zig", "optimize_code", { code: ` pub fn fibonacci(n: u64) u64 { if (n <= 1) return n; return fibonacci(n - 1) + fibonacci(n - 2); } `, optimizationLevel: "ReleaseFast" });

2. Estimate Compute Units

const result = await useMcpTool("zig", "estimate_compute_units", { code: ` pub fn bubbleSort(arr: []i32) void { var i: usize = 0; while (i < arr.len) : (i += 1) { var j: usize = 0; while (j < arr.len - 1) : (j += 1) { if (arr[j] > arr[j + 1]) { const temp = arr[j]; arr[j] = arr[j + 1]; arr[j + 1] = temp; } } } } ` });

3. Generate Code

const result = await useMcpTool("zig", "generate_code", { prompt: "Create a thread-safe counter struct", context: "Should use atomic operations and handle overflow" });

4. Get Recommendations

const result = await useMcpTool("zig", "get_recommendations", { code: ` pub fn main() !void { var list = std.ArrayList(u8).init(allocator); var i: u32 = 0; while (true) { if (i >= 100) break; try list.append(@intCast(u8, i)); i += 1; } } `, prompt: "performance" });
