Browser Proxy

The Browser Proxy is a separate Docker service that provides headless browser automation via Playwright. It is NOT part of the Synapse API directly — Synapse endpoints do not include /browser/* paths.

Access Methods

Method 1: Via Synapse MCP Server (recommended)

The Synapse MCP server exposes browser tools as MCP tools. Use this for LLM-driven browser automation:

// Claude Desktop config
{
  "mcpServers": {
    "synapse": {
      "command": "npx",
      "args": ["-y", "synapse-mcp-api@latest"],
      "env": {
        "SYNAPSE_MIND_KEY": "mk_...",
        "SYNAPSE_URL": "https://synapse.schaefer.zone"
      }
    }
  }
}

Available MCP browser tools:

• browser_new — open a new browser tab
• browser_navigate — navigate to a URL
• browser_click — click an element
• browser_type — type text into a field
• browser_screenshot — capture a screenshot
• browser_close — close the tab
• (and more — see MCP integration)

Method 2: Direct Browser Proxy Access

For non-MCP integrations, connect directly to the browser-proxy service:

# Health check
curl http://browser-proxy.schaefer.zone:13000/health

# Open a page
curl -X POST http://browser-proxy.schaefer.zone:13000/navigate \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

Common Use Cases

Web scraping

# Via MCP (Claude Desktop)
"Use browser_navigate to open https://news.ycombinator.com, 
 then extract the top 10 story titles."

Form automation

# Via MCP
"Use browser_navigate to open the login page,
 browser_type to fill username and password,
 browser_click to submit the form."

Screenshot capture

# Via MCP
"Take a screenshot of https://example.com and save it."
