ZenLink MCP server

ZenLink MCP

MCP server for browser automation via ZenLink — gives Claude Desktop and other MCP clients native browser control through Zen Browser (Firefox-based).

v2.0.0 ships ~50 new tools for parallel agentic work: real multi-tab parallelism, tab unloader defense, session save/restore, Readability + Markdown extraction, request interception, cookies/storage, and orchestration primitives (broadcast, sync barriers, tab pools, named tags). See CHANGELOG.md for the full list.

pip install zenlink-mcp

Requirements

• ZenLink browser extension v2.0.0+ installed in Zen Browser

Waits for a CSS selector to appear and become visible on the page. Returns immediately when found rather than sleeping a fixed duration — use this instead of sleep when waiting for dynamic/JS-rendered content.
