Remote Control Server for Claude Code

A self-hosted server that enables real-time, bidirectional web-based interaction with Claude Code CLI sessions.

Important: If you're on an official Claude subscription, the built-in Remote Control already works out of the box. But if you're using the API directly, or running Deepseek / GLM / Kimi / Minimax on Claude Code, this project will be a game-changer.

Why Remote Control?

Claude Code stores conversation history as local JSONL files (~/.claude/projects/.../). Reading these files only gives you a static, after-the-fact view of what happened.

Remote Control mode is fundamentally different:

Real-time streaming — See Claude's responses, tool calls, and reasoning as they happen, not after.
Bidirectional interaction — Send messages, approve/deny tool permissions, and answer elicitations from the Web UI. You are a participant, not a spectator.
Multi-device access — Open the Web UI from any browser on any device on your network.

Architecture

Browser (Web UI)
    ↕  WebSocket /api/ws/:sessionId
Remote Control Server (this project)
    ↕  WebSocket /v2/session_ingress/ws/:sessionId
    ↕  HTTP POST /v2/session_ingress/session/:sessionId/events
Claude Code CLI (bridge mode)

The CLI runs in bridge mode, registering itself as an "environment" with the server. When a session is created via the Web UI, the server dispatches work to the CLI. The CLI spawns a subprocess that connects back to the server via WebSocket + HTTP POST (HybridTransport), streaming all events in real time.

Quick Start

1. Install Dependencies

cd remote-control-server
npm install

2. Build & Run

npm run build
npm start

Or for development with auto-reload:

npm run dev

The server starts on http://0.0.0.0:3000 by default. Open http://localhost:3000 in your browser to access the Web UI.

3. Configuration

Environment variables:

Variable	Default	Description
`PORT`	`3000`	Server listen port
`HOST`	`0.0.0.0`	Server bind address
`DEBUG`	(unset)	Set to any value to enable request logging

Patching Claude Code to Use a Self-Hosted Server

Claude Code's bridge mode has two BASE_API_URL configs: the prod config points to https://api.anthropic.com, and the local/dev config points to http://localhost:3000. To point it at your self-hosted server, you need to patch the CLI binary.

Note: The CLI binary is minified/obfuscated — function names and line numbers change every release. All instructions below use version-independent patterns (stable string constants + regex with [[:space:]]* for optional whitespace) that work across CLI versions regardless of minification style.

Platform note: sed -i syntax differs: Linux (GNU sed) uses sed -i, macOS (BSD sed) uses sed -i ''. The one-click script at the end handles this automatically.

Auto-Detecting the CLI Path

The CLI path changes with Node.js version. Auto-detect instead of hardcoding:

CLI_JS="$(readlink -f "$(which claude)" 2>/dev/null)" \
    || CLI_JS="$(realpath "$(which claude)" 2>/dev/null)" \
    || CLI_JS="$(which claude)"
echo "CLI: $CLI_JS"

Locating the Relevant Code

Use grep to find the code you need to patch. These patterns are version-independent:

# 1. Find the hardcoded BASE_API_URL (prod config)
grep -n 'BASE_API_URL.*api\.anthropic\.com' "$CLI_JS"

# 2. Find the OAuth URL allowlist
grep -n 'beacon.claude-ai.staging.ant.dev' "$CLI_JS"

# 3. Find the HTTP enforcement check (2.1.63+)
grep -n 'Remote Control base URL uses HTTP' "$CLI_JS"

# 4. Find the WebSocket URL derivation (v1 vs v2 routing, 2.1.63+)
grep -n 'session_ingress/ws/' "$CLI_JS"

# 5. Find the tengu_ccr_bridge feature flag
grep -n 'tengu_ccr_bridge' "$CLI_JS"

# 6. Find the hardcoded skipSlashCommands flag (remote bridge messages)
grep -n 'skipSlashCommands' "$CLI_JS"

Patch Method

Option A: Patch the hardcoded URL directly

Replace https://api.anthropic.com in the prod config with your server's URL:

# Example: point to a remote server at 192.168.1.100:3000
# [[:space:]]* handles both minified (no space) and pretty-printed (with space) JS
sed -E -i 's|BASE_API_URL:[[:space:]]*"https://api\.anthropic\.com"|BASE_API_URL:"http://192.168.1.100:3000"|' "$CLI_JS"

Option B: Bypass the allowlist for CLAUDE_CODE_CUSTOM_OAUTH_URL

The CLI supports CLAUDE_CODE_CUSTOM_OAUTH_URL but validates it against a hardcoded allowlist. Find the allowlist by searching for beacon.claude-ai.staging.ant.dev and add your URL:

# Find the allowlist array (contains "beacon.claude-ai.staging.ant.dev")
grep -n 'beacon.claude-ai.staging.ant.dev' "$CLI_JS"

# Add your server URL to the allowlist array, then set the env var:
sed -i 's|"https://beacon.claude-ai.staging.ant.dev"|"https://beacon.claude-ai.staging.ant.dev","https://your-server.example.com"|' "$CLI_JS"
export CLAUDE_CODE_CUSTOM_OAUTH_URL=https://your-server.example.com

Important Notes

HTTP vs HTTPS (2.1.63+): The CLI enforces HTTPS for non-localhost URLs (search for Remote Control base URL uses HTTP). If your server uses plain HTTP on a non-localhost address, you must either:

Set up a reverse proxy with TLS (recommended)
Patch out the HTTP check:

# Version-independent: matches any variable name and handles optional whitespace
sed -E -i 's/[a-zA-Z_$]+\.startsWith\("http:\/\/"\)[[:space:]]*&&[[:space:]]*![a-zA-Z_$]+\.includes\("localhost"\)[[:space:]]*&&[[:space:]]*![a-zA-Z_$]+\.includes\("127\.0\.0\.1"\)/false/' "$CLI_JS"

WebSocket URL derivation (2.1.63+): The CLI automatically derives the WebSocket URL from api_base_url:
- For localhost / 127.0.0.1: uses ws:// and /v2/ prefix
- For all other hosts: uses wss:// and /v1/ prefix
If your self-hosted server only supports /v2/ routes (like this project does), and is not on localhost, force both branches to return v2:
```
# Version-independent: matches the ?"v2":"v1" ternary regardless of variable names
sed -E -i 's/\?[[:space:]]*"v2"[[:space:]]*:[[:space:]]*"v1"/?"v2":"v2"/' "$CLI_JS"
```
Work secret api_base_url: The server embeds its own URL in the work secret. If your server is accessible at a different address than localhost:${PORT} (e.g., behind a reverse proxy), set the API_BASE_URL env var:
```
# Set the externally-reachable address of your server
export API_BASE_URL=http://your-external-address:3000
```

Unlocking the /remote-control command (2.1.63+): The remote-control (aka claude remote-control) command is gated behind the tengu_ccr_bridge feature flag. Even after patching BASE_API_URL, the command remains hidden and blocked. You need 3 code patches + 1 env var:

# Patch 1: Bypass feature flag entirely (makes command visible + sync check always passes)
# Version-independent regex: matches any function name calling tengu_ccr_bridge
sed -E -i 's/[A-Za-z0-9_]+\("tengu_ccr_bridge",[[:space:]]*!1\)/!0/g' "$CLI_JS"

# Patch 2a: Neutralize async flag check (CLI command path)
sed -i 's/console.error("Error: Remote Control is not yet enabled for your account."), process.exit(1)/void 0/' "$CLI_JS"

# Patch 2b: Neutralize async flag check (interactive mode path)
sed -i 's/return "Remote Control is not enabled. Wait for the feature flag rollout."/return null/' "$CLI_JS"

# Patch 3: Neutralize async flag check in bridge init (REPL path)
# Version-independent regex: matches any function name calling tengu_ccr_bridge
# Note: On 2.1.68+ the async check is already hardcoded to return true, making this a no-op
sed -E -i 's/return [A-Za-z0-9_]+\("tengu_ccr_bridge"\)/return !0/' "$CLI_JS"

Additionally, the command requires OAuth credentials. If you don't have a claude.ai account (e.g., API-only or third-party model users), set this env var to bypass all OAuth checks:

# The self-hosted server doesn't validate the Authorization header, so any value works
export CLAUDE_CODE_OAUTH_TOKEN=self-hosted

Note: If you already have a claude.ai account and are logged in, you only need Patch 1-2 above. The CLAUDE_CODE_OAUTH_TOKEN env var is only needed for users without a claude.ai account.

Enabling slash commands for remote messages: The CLI disables slash command processing for messages received from the remote bridge (skipSlashCommands: !0). This means /commit, /compact, /clear etc. are treated as plain text. To enable them:
```
# Version-independent: enable slash commands for remote bridge messages
sed -E -i 's/skipSlashCommands:[[:space:]]*!0/skipSlashCommands:!1/g' "$CLI_JS"
```
After patching:
- prompt type commands (/commit, /review etc.) → expanded as system prompts and sent to Claude, works normally
- local type commands (/clear, /compact) → executed locally in the CLI
- local-jsx + immediate commands (/plan, /model, /mcp) → require TUI to be active, may not work in all bridge modes
