Claude Proxy Monitor

One-click start, stop, and configure the claude-proxy reverse proxy without leaving VS Code.

The extension auto-downloads the latest release binary, starts the proxy locally, and sets ANTHROPIC_BASE_URL in your integrated terminal so Claude tools (Claude Code, Claude Agent SDK) route through the proxy transparently.

How it works

claude-proxy sits between your Claude tools and api.anthropic.com. Every request passes through it unchanged by default — it only reroutes a request when its model field matches a rule you configure (e.g. send deepseek-* calls to DeepSeek instead of Claude). Everything else is forwarded to Anthropic as-is, while the proxy records tokens, tool calls, and full request/response content for the dashboard.

    C --> E["Response streamed back"]
    D --> E

Two capabilities come out of this:

1. Proxy — selective request routing

• Requests are forwarded to api.anthropic.com untouched unless the request's model matches a configured rule.
• Matching rules (configured on the Setup page) redirect just that request to DeepSeek or OpenRouter, with the target model swapped in — other requests keep going to Anthropic normally.
• Routing is re-read from config.json on every request, so changes made in Setup apply immediately, without restarting.
• Optional system-prompt injection can also be scoped to a model match.

2. Monitor — live dashboard

• Request list — every request that passes through the proxy (to Anthropic or an alternate provider) shows up in a live, auto-refreshing list with model, token usage, and tool names.
• Request detail — click into any request to see the full conversation timeline: system prompt, user/assistant turns, tool calls and their results, and token/cache usage for that exchange.
• Status bar surfaces running state, port, rate-limit usage, and DeepSeek balance without opening the dashboard at all.

Features

• Auto-download — fetches the correct platform binary from GitHub Releases on first start
• Status bar — running state, port, rate-limit usage, and DeepSeek balance at a glance
• One-click commands — Start, Stop, Restart, Open Dashboard, Open Setup, Show Logs, Check for Update
• Health monitoring — polls the proxy's health endpoint every 60s and surfaces rate-limit warnings and Claude subscription usage in the status bar
• Auto-config — sets ANTHROPIC_BASE_URL in your terminal environment on start, restores it on stop

Commands

Open the Command Palette (Ctrl+Shift+P) and type "Claude Proxy":

Settings

• claudeProxy.port — port the proxy listens on (default 8080)
• claudeProxy.autoStart — start the proxy automatically when VS Code opens (default false)
• claudeProxy.devBinary — path to a local dev binary; when set, skips GitHub download entirely

Requirements

• Windows or Linux (amd64)
• No other process on the configured port
