Anvil

Command-line interface and MCP server for the Sable AI voice agent platform.

Quick Start (2 minutes)

bash

# 1. Install
go install github.com/sable-inc/anvil/cmd/anvil@latest

# 2. Authenticate
anvil auth login --token svc_your_token_here

# 3. Set your default org
mkdir -p ~/.config/anvil
cat > ~/.config/anvil/config.yaml << 'EOF'
default_org: "your-org"
api_url: "https://api.withsable.com"
EOF

# 4. Set up shell completions (zsh)
echo 'source <(anvil completion zsh)' >> ~/.zshrc
source ~/.zshrc

# 5. Verify
anvil auth status
anvil agent list

Install

Option 1: Homebrew (recommended)

bash

brew install sable-inc/tap/anvil

Option 2: Go Install

bash

go install github.com/sable-inc/anvil/cmd/anvil@latest

This puts the anvil binary in $GOPATH/bin (usually ~/go/bin). Make sure that's in your $PATH:

server.ts

# Add to your shell profile if not already there
export PATH="$HOME/go/bin:$PATH"

Option 3: Download Binary (no Go required)

Download the latest release from GitHub Releases:

macOS (Apple Silicon):

Terminal

curl -sL https://github.com/sable-inc/anvil/releases/latest/download/anvil_darwin_arm64.tar.gz | tar xz
sudo mv anvil /usr/local/bin/

macOS (Intel):

Terminal

curl -sL https://github.com/sable-inc/anvil/releases/latest/download/anvil_darwin_amd64.tar.gz | tar xz
sudo mv anvil /usr/local/bin/

Linux (amd64):

Terminal

curl -sL https://github.com/sable-inc/anvil/releases/latest/download/anvil_linux_amd64.tar.gz | tar xz
sudo mv anvil /usr/local/bin/

Or download manually from the Releases page.

Option 4: Build from Source

bash

git clone https://github.com/sable-inc/anvil.git
cd anvil
make build
sudo mv bin/anvil /usr/local/bin/

Verify Installation

bash

anvil version
# anvil v0.1.0 (commit: abc1234, built: 2026-02-14T..., darwin/arm64)

Authentication

Anvil authenticates with sable-api using a service token:

bash

# Store your token (one-time)
anvil auth login --token svc_your_token_here

# Verify it works
anvil auth whoami    # shows stored token info
anvil auth status    # verifies API connectivity

Credentials are stored in ~/.config/anvil/credentials.json (file permissions: 0600).

To get a service token, ask your team admin or generate one in the Sable Platform dashboard.

Configuration

Create ~/.config/anvil/config.yaml:

yaml

default_org: "my-org"
api_url: "https://api.withsable.com"
format: "table"

Override any setting with flags:

bash

anvil --org other-org --format json agent list

Setting	Flag	Config Key	Description
Organization	`--org`	`default_org`	Default org for all commands
API URL	`--api-url`	`api_url`	Sable API base URL
Output format	`--format`	`format`	`table`, `json`, or `yaml`
No color	`--no-color`	—	Disable colored output
Verbose	`--verbose`	—	Enable debug logging

Shell Completions

Anvil has dynamic tab completions that suggest real resource names from the live API.

Setup (one-time, permanent)

Zsh (default on macOS):

bash

echo 'source <(anvil completion zsh)' >> ~/.zshrc
source ~/.zshrc

Bash:

bash

echo 'source <(anvil completion bash)' >> ~/.bashrc
source ~/.bashrc

Fish:

bash

anvil completion fish > ~/.config/fish/completions/anvil.fish

PowerShell:

powershell

anvil completion powershell >> $PROFILE

What You Get

After setup, press TAB anywhere:

Code

anvil <TAB>                      # all subcommands
anvil agent get <TAB>            # suggests agent slugs + IDs from API
anvil journey delete <TAB>       # suggests journey slugs + IDs
anvil kb sync <TAB>              # suggests KB item IDs with names
anvil config pull <TAB>          # suggests config version IDs
anvil connect <TAB>              # suggests agent slugs
anvil --format <TAB>             # suggests table, json, yaml

Completions fetch live data from the API using your stored token. If you're not authenticated, it gracefully shows no suggestions (no errors).

FAQ

Do I need to regenerate completions when anvil or my shell updates? No. The source <(anvil completion ...) pattern re-generates on every new shell session automatically. For Fish, re-run the file write command after updating anvil if new commands were added.

$EDITOR agent.yaml

# Validate locally (no API call needed)
anvil config validate agent.yaml

# See what changed
anvil config diff agent.yaml --id <config-id>

# Push the updated config
anvil config push agent.yaml

MCP Server (for AI Assistants)

Anvil includes an MCP server (28 Sable tools + 5 HyperDX observability tools) for AI coding assistants like Claude Code, Cursor, Windsurf, etc.

One-Time Setup

bash

anvil auth login --token svc_your_token     # Sable API credentials
anvil settings set-hyperdx hdx_your_key     # HyperDX API key (optional)

Add to Cursor

Paste this in your browser to install with one click:

Code

cursor://anysphere.cursor-deeplink/mcp/install?name=sable&config=eyJjb21tYW5kIjoiYW52aWwiLCJhcmdzIjpbIm1jcCIsInNlcnZlIl19

Or add manually to .cursor/mcp.json:

config.json

{
  "mcpServers": {
    "sable": {
      "command": "anvil",
      "args": ["mcp", "serve"]
    }
  }
}

Add to Claude Code

Terminal

claude mcp add sable -s user -- anvil mcp serve

No secrets in the config -- anvil reads credentials from ~/.config/anvil/.

Other Editors (Windsurf, etc.)

Add the same JSON config to your editor's MCP settings file.

Releasing New Versions

Anvil uses goreleaser with GitHub Actions for automated releases.

Creating a Release

bash

git tag v0.1.0
git push origin v0.1.0

GitHub Actions will automatically:

Build binaries for Linux, macOS, and Windows (amd64 + arm64)
Create a GitHub Release with downloadable archives
Generate checksums and a changelog
Publish to the Homebrew tap (sable-inc/homebrew-tap)
Publish to the MCP Registry (discoverable in Claude Code / Cursor)

Team members can then upgrade via:

bash

# Homebrew
brew upgrade anvil

# Go install
go install github.com/sable-inc/anvil/cmd/anvil@latest

Snapshot Build (local testing)

bash

goreleaser --snapshot --clean
ls dist/

Development

bash

make build     # Build binary
make test      # Run tests with race detector
make lint      # Run golangci-lint v2
make check     # Build + test + lint
make install   # Install to $GOPATH/bin
make generate  # Generate API client from OpenAPI spec
make clean     # Remove build artifacts

Requires:

Go 1.26+
golangci-lint v2 (for make lint)
Running sable-api instance (for make generate)

CI/CD

GitHub Actions runs automatically:

CI (.github/workflows/ci.yml): build + test + lint on every push and PR
Release (.github/workflows/release.yml): goreleaser on version tags (v*)
