概要

What is Mcp Selenium Haskell?

Mcp Selenium Haskell is a Haskell implementation of an MCP (Model Context Protocol) Selenium server that uses WebDriver to enable browser automation through standardized MCP clients like Claude. It provides multi-session browser management with UUID-based session isolation and connects to a Selenium Grid.

How to use Mcp Selenium Haskell?

Run the statically-linked executable mcp-selenium-hs after setting environment variables SELENIUM_HOST (default 127.0.0.1) and SELENIUM_PORT (default 4444) to point to a Selenium server. Configure Claude Desktop by adding a JSON entry with the command and environment variables, or expose the server over HTTP/SSE using mcp-proxy for remote access.

Key features of Mcp Selenium Haskell

Multi-session browser management with UUID-based session IDs
Element interaction: click, type, hover, drag and drop
Element location via CSS, XPath, ID, name, class, tag
JavaScript console logging with injection and monitoring
Screenshot capture and page source retrieval
File upload and keyboard input simulation
Chrome and Firefox support with headless mode
Statically-linked executable with zero runtime dependencies

Use cases of Mcp Selenium Haskell

Automate browser tasks through MCP clients like Claude
Run multiple concurrent browser sessions for parallel testing
Integrate with existing Selenium Grid infrastructure
Perform headless browser automation without a graphical display

FAQ from Mcp Selenium Haskell

How does Mcp Selenium Haskell differ from the Node.js mcp-selenium?

This Haskell version supports multiple concurrent sessions (Node.js uses a single implicit session), connects to Selenium Grid, provides additional tools (console logging, page source), and is delivered as a static binary. It requires a separate Selenium server whereas the Node.js version includes browser management.

What environment variables are required?

Set SELENIUM_HOST (default 127.0.0.1) and SELENIUM_PORT (default 4444) to point to your Selenium WebDriver server. For local use no configuration is needed if using defaults.

How do I configure Claude Desktop to use this server?

Add a JSON entry to claude_desktop_config.json with "command": "mcp-selenium-hs" and the required environment variables under "env". The configuration file location varies by OS.

Can I run multiple browser sessions at once?

Yes, Mcp Selenium Haskell explicitly manages multiple concurrent sessions using UUID-based session IDs, unlike the single-session model of the Node.js version.

How can I expose the server remotely?

Use mcp-proxy to serve the MCP server over SSE (e.g., mcp-proxy --port=8080 mcp-selenium-hs). Bind to a specific private interface (Tailscale IP, localhost with SSH forwarding) and never use 0.0.0.0 in production.
