Zig MCP Server

What is Zig MCP Server?

A Model Context Protocol (MCP) server that provides Zig language tooling, code analysis, and documentation access. It enhances AI capabilities with Zig‑specific functionality including code optimization, compute unit estimation, code generation, and best practices recommendations.

How to use Zig MCP Server?

Install by cloning the repo, running npm install and npm run build, then set the GITHUB_TOKEN environment variable. Add the server to your MCP client configuration with the command node pointing to the built index.js. Invoke tools like optimize_code, estimate_compute_units, generate_code, and get_recommendations via your MCP client.

Key features of Zig MCP Server

• Optimize Zig code with four optimization levels (Debug, ReleaseSafe, ReleaseFast, ReleaseSmall)
• Estimate computational complexity, memory usage, and allocation patterns
• Generate Zig code from natural language descriptions
• Get code improvement recommendations on style, design, safety, and performance
• Access official language reference and standard library documentation
• Explore popular Zig repositories and community examples

Use cases of Zig MCP Server

• Automatically optimize Zig functions for speed or safety
• Estimate resource usage and complexity of new Zig algorithms
• Generate boilerplate Zig code from plain English prompts
• Review existing Zig code for performance and best-practice improvements
• Fetch official Zig docs and real‑world repository patterns during development

FAQ from Zig MCP Server

What are the dependencies to run Zig MCP Server?

Node.js and npm are required. A GitHub token with public_repo scope is recommended for better API rate limits.

How do I configure Zig MCP Server?

Set the GITHUB_TOKEN environment variable and add the server to your MCP settings with the command node, arguments pointing to the built index.js, and the environment variable set.

What resources does Zig MCP Server provide?

It provides three resources: language reference (zig://docs/language-reference), standard library documentation (zig://docs/std-lib), and a list of popular Zig repositories (zig://repos/popular).

What tools are available?

Four tools are available: optimize_code, estimate_compute_units, generate_code, and get_recommendations. Each accepts specific parameters detailed in the README.

Does Zig MCP Server require an external service?

It uses the GitHub API to fetch popular repository data. A GitHub token is recommended to avoid rate limits, but the server also provides local documentation without external access.
