Amp

Configure Sourcegraph's Amp coding agent to route through Revo Mail using CLIProxyAPI for unified model access and billing.

What This Does

Amp is Sourcegraph's frontier coding agent for the terminal and editor. It supports multiple agent modes — smart, rush, and deep — and integrates with IDEs like VS Code, JetBrains, and Zed. By routing Amp through Revo Mail via CLIProxyAPI, you can use any supported model while consolidating your AI spend under a single Revo Mail account.

Amp's native BYOK (Isolated Mode) has been removed. To use Revo Mail with Amp, you need CLIProxyAPI — a lightweight proxy server that intercepts Amp's API calls and routes them through your Revo Mail endpoint.

Setup

Step 1: Install Amp

curl -fsSL https://ampcode.com/install.sh | bash

Or via npm:

npm install -g @anthropic-ai/amp

Step 2: Install CLIProxyAPI

CLIProxyAPI is a proxy server that wraps Amp's API calls to route through custom providers:

docker pull eceasy/cliproxyapi

Or install from source:

git clone https://github.com/router-for-me/CLIProxyAPI.git
cd CLIProxyAPI

Step 3: Configure CLIProxyAPI

Create a config.yaml for CLIProxyAPI:

config.yaml

server:
  port: 3456
  upstream-url: "https://ampcode.com"
  upstream-api-key: "YOUR_AMP_API_KEY"
  restrict-management-to-localhost: true

model-mappings:
  claude-opus-4-6: "gpt-5.4"
  claude-sonnet-4-6: "gpt-5.3-codex"
  claude-haiku-4-6: "glm-5-turbo"

force-model-mappings: true

custom-providers:
  - name: "Revo Mail"
    base-url: "https://api.revomail.io/v1"
    api-key: "YOUR_Revo Mail_API_KEY"
    models:
      - "gpt-5.4"
      - "gpt-5.3-codex"
      - "gpt-5.2"
      - "gemini-3.1-pro"
      - "glm-5-turbo"
      - "glm-5"

Replace YOUR_AMP_API_KEY with your Amp key from ampcode.com/settings and YOUR_Revo Mail_API_KEY with your Revo Mail key from revomail.io/keys.

Step 4: Start CLIProxyAPI

docker run -d \
  --name cliproxyapi \
  -p 3456:3456 \
  -v ./config.yaml:/CLIProxyAPI/config.yaml \
  eceasy/cliproxyapi

Step 5: Configure Amp to Use the Proxy

Point Amp to the local proxy by setting environment variables:

export ANTHROPIC_BASE_URL="http://localhost:3456"
export ANTHROPIC_API_KEY="YOUR_Revo Mail_API_KEY"

Add these to your ~/.zshrc or ~/.bashrc to persist across sessions.

Step 6: Verify the Connection

Run Amp and start a conversation:

amp

Try a simple prompt to confirm the proxy is routing requests through Revo Mail.

Recommended Models for Amp

Amp Mode	Mapped Model	Why
Smart (complex tasks)	`gpt-5.4`	Highest reasoning capability
Rush (quick tasks)	`glm-5-turbo`	Fast, low latency
Deep (extended thinking)	`gpt-5.3-codex`	Optimized for code reasoning
Large codebase analysis	`gemini-3.1-pro`	1M+ token context

IDE Integrations

Amp also works with IDEs. After configuring CLIProxyAPI, connect Amp to your editor:

IDE	Setup
VS Code / Cursor / Windsurf	Install Amp CLI, ensure editor is running, then run `amp`
JetBrains	Install Amp CLI, then run `amp --jetbrains`
Zed	Install Amp CLI, ensure Zed is running, then run `amp`
Neovim	Install Amp CLI and the Amp Neovim plugin, then run `amp`

Use the command palette (Ctrl+O) and select ide connect to link Amp with your editor.

Troubleshooting

Proxy not starting

Verify Docker is running: docker ps
Check CLIProxyAPI logs: docker logs cliproxyapi
Ensure port 3456 is not in use: lsof -i :3456

Amp connection errors

Confirm the proxy is running at http://localhost:3456
Verify ANTHROPIC_BASE_URL is set correctly
Test the proxy directly: curl http://localhost:3456/health

Model mapping not working

Check that force-model-mappings: true is set in your CLIProxyAPI config
Verify the model names in model-mappings match what Amp requests
Review CLIProxyAPI logs for unmapped model requests

Authentication errors

Ensure your Revo Mail API key is valid at revomail.io/keys
Check that the custom-providers section has the correct api-key

Notes

Amp's native Isolated Mode (BYOK) has been removed — CLIProxyAPI is the recommended way to use custom providers
The model-mappings section translates Amp's default model names to Revo Mail models
All token consumption routed through Revo Mail appears in your dashboard in real-time
Amp uses AGENTS.md files for project-specific guidance — these work independently of the proxy setup
