What is Obscura?

Obscura is a Rust-based headless browser engine that provides both a Chrome DevTools Protocol (CDP) server and an MCP (Model Context Protocol) server. Run web automation, scraping, and AI-agent workflows without Chrome, Chromium, or Node.js — just a single native binary (~40MB) with built-in stealth mode and AI-optimized content extraction.

Build from Source

Prerequisites: Rust 1.75+ (install via rustup.rs)

cargo build --release

Note: First build takes ~5 minutes due to V8 compilation. Subsequent builds use cached artifacts.

The binary will be at target/release/obscura.

MCP Setup

Claude Desktop (macOS / Linux / Windows)

Edit ~/.config/Claude/claude_desktop_config.json (or %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "obscura": {
      "command": "~/.cargo/bin/obscura",
      "args": ["mcp"]
    }
  }
}

Note: Replace ~/.cargo/bin/obscura with the full path to your binary if it's not in the default Cargo installation directory.

Restart Claude Desktop. Obscura tools will appear in the Tools panel.

Cursor

Edit .cursor/mcp.json:

{
  "mcpServers": {
    "obscura": {
      "command": "~/.cargo/bin/obscura",
      "args": ["mcp"]
    }
  }
}

Restart Cursor.

Claude Code (CLI)

Add to your Claude Code settings:

# ~/.claude/settings.json or ~/.claude/settings.local.json
{
  "mcpServers": {
    "obscura": {
      "command": "~/.cargo/bin/obscura",
      "args": ["mcp"]
    }
  }
}

Then restart the Claude Code CLI.
