Network Versions

This plugin supports multiple Aztec network versions with potentially different syntax. Switch between them based on your target deployment:

# Clone with a specific network version
git clone https://github.com/critesjosh/aztec-claude-plugin
cd aztec-plugin
./setup.sh testnet  # or: mainnet, devnet

Available Networks

Network	Description	Use Case
mainnet	Stable production release	Production deployments
testnet	Pre-release testing	Integration testing
devnet	Latest development	Experimenting with new features

Switching Networks

# Switch to a different network
./setup.sh devnet

# Check current network
./setup.sh status

See NETWORK.md for detailed version differences.

Aztec MCP Server

This plugin includes the @aztec/mcp-server which provides local access to Aztec documentation, examples, and source code.

Features

• Repository Cloning - Clones aztec-packages, aztec-examples, and aztec-starter locally
• Code Search - Regex-based search across Noir contracts and TypeScript files
• Documentation Search - Search Aztec docs by section
• Example Discovery - List and read example contracts

Switching Versions

The plugin defaults to a specific Aztec version. To switch versions:

Option 1: Use the /aztec-version command

/aztec-version                    # Autodetect from project's Nargo.toml
/aztec-version v3.0.0-devnet.7    # Use specific version

The command will automatically detect the Aztec version from your project's Nargo.toml if no version is specified.

Option 2: Call aztec_sync_repos directly

aztec_sync_repos({ version: "v3.0.0-devnet.7", force: true })

Check current version:

aztec_status()

Find available versions at aztec-packages tags.
