    "incantation": "When exposing agent-browser automation to an MCP client, start the stdio server with `agent-browser mcp`; use the default `core` profile or select `all` or comma-separated profiles with `--tools`.",

    "gotchas": [
      "Version: v0.28.0",
      "--tools: Select MCP tool profiles; defaults to `core`. `all` selects every MCP tool; comma-separated profile names compose profiles. The docs do not state that profiles are mutually exclusive.",
      "core: Default profile: navigation, snapshots, interaction, waits, reads, screenshots, JavaScript eval, close, tab basics, and profile discovery.",
      "network: Profile for network routes, request inspection, HAR, headers, credentials, and offline controls.",
      "state: Profile for cookies, storage, auth, saved state, sessions, profiles, and skills.",
      "debug: Profile for console/errors, tracing, profiling, recording, clipboard, plugins, doctor, dashboard, install, upgrade, chat, diff, batch, and confirm/deny.",
      "tabs: Profile for back/forward/reload, tabs, windows, frames, and dialogs.",
      "react: Profile for React tree/inspect/renders/suspense, vitals, and pushstate.",
      "mobile: Profile for viewport/device/geolocation/media, touch, swipe, mouse, and keyboard.",
      "all: Every MCP tool, including the full typed CLI parity surface.",
      "Prerequisite: Configure the MCP client to launch command `agent-browser` with args `[\"mcp\"]`; the server communicates over stdio.",
      "The server uses stdio.",
      "The default `core` profile keeps context small."
