Model Context Protocol in Elcro.
MCP (Model Context Protocol) lets Elcro attach external tool servers (browser automation, databases, SaaS APIs) to the chat agent.
When a server is connected and toggled on, its tools appear in the model’s tool catalog (names prefixed with the server id, e.g. playwright_browser_navigate).
Mental model
mcp.json → MCP service → tool list on each chat turn → model tool call → MCP execute → result in thread
Built-in Agent Browser vs MCP Playwright
Elcro ships Agent Browser builtins (browser_navigate, …). MCP Playwright is separate. When MCP is connected and you ask to “use MCP”, the agent should call MCP-prefixed tools.
