What is mcp server?
An MCP server implements the Model Context Protocol so any compatible AI client can discover and call its tools over a standard interface. Twin’s MCP server exposes the execution layer as tools — `run` (execute a goal), `compile_skill`, and `run_skill` — so an agent in Cursor, Claude Desktop, Claude Code, or Cline can drive a real browser without bespoke integration code.
Why it matters
MCP is becoming the universal socket between agents and tools. Shipping a Twin MCP server means your IDE or desktop agent gets a browser — plus the semantic cache and replay economics — by adding one server, instead of wiring an SDK per client.
