What is the Obscura MCP MCP server?

Obscura MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Obscura MCP directly instead of describing what you should do. MCP server adapter for Obscura Rust headless browser — web scraping with anti-detection.

What you get

An MCP server adapter for Obscura, a lightweight Rust headless browser for scraping and AI agent automation.

  • No Chrome — — pure Rust, no 200 MB browser bundle
  • CDP-native — — exposes Chrome DevTools Protocol directly
  • Anti-detection — — built-in stealth for scraping-resistant sites
  • Tiny footprint — — ~15 MB binary, starts in milliseconds

What the assistant can call

Once Obscura MCP is connected, these are the calls the assistant has available:

  • urls — string[]
  • eval — string
  • concurrency — number
  • timeout — number

Configuration and credentials

You will need 2 environment variables: OBSCURA_PATH, MCP_HTTP_HOST. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

obscura-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Choosing this one

Plenty of browser automation servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Obscura MCP's toolset — urls, eval, concurrency and 1 more — is a fair guide to whether it matches your workflow. It is maintained by Metadrama; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the obscura mcp mcp server does with a few real requests.
