# Zig Docs MCP
MCP server providing up-to-date Zig documentation and builtin functions.
## Installation
### Claude Code
```bash
claude mcp add zig-docs npx -y zig-docs-mcp --version master --update-policy manual
```
### Claude Desktop
Add to your MCP configuration:
```json
{
"mcpServers": {
"zig-docs": {
"command": "npx",
"args": ["-y", "zig-docs-mcp", "--version", "master", "--update-policy", "manual"]
}
}
}
```
## Tools
- **`list_builtin_functions`** - Lists all available Zig builtin functions. Builtin functions are provided by the compiler and are prefixed with '@'. The comptime keyword on a parameter means that the parameter must be known at compile time. Use this to discover what functions are available, then use 'get_builtin_function' to get detailed documentation.
- **`get_builtin_function`** - Search for Zig builtin functions by name and get their documentation, signatures, and usage information. Returns all matching functions ranked by relevance.
## Commands
The CLI provides flexible options for version control and update management:
```bash
# Start MCP server with defaults (master branch, manual updates)
zig-docs-mcp
# Use specific Zig version
zig-docs-mcp --version 0.13.0
# Enable automatic daily updates
zig-docs-mcp --update-policy daily
# Update documentation without starting server
zig-docs-mcp update --version 0.14.1
```
**Version options**:
- `master` (default) - Latest development version from Zig's master branch
- `0.13.0`, `0.12.0`, etc. - Specific Zig release versions
**Update policies**:
- `manual` (default) - No automatic updates, manual control only
- `daily` - Check for documentation updates once per day
- `startup` - Update documentation every time the server starts
## Cache
Documentation is fetched from ziglang.org and cached in platform-specific directories:
- Linux: `~/.cache/zig-docs-mcp/`
- macOS: `~/Library/Caches/zig-docs-mcp/`
- Windows: `%LOCALAPPDATA%\zig-docs-mcp\`
