It's wired up with storage, credentials, the session's bearer token, and configuration for reading the projects binding. This is controlled by a feature gate.\n\n**Why**\n\nThis lays groundwork for connecting headless sessions to a webagent MCP bridge, though it isn't enabled for general use yet.\n\n- Flag `tengu_webagent_mcp_bridge`: Off in both readings (read for one account on one subscription tier against v2.1.273; this account: off, anonymous baseline: off, compiled default: not a boolean we can read) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Remote Control\n- Tier: Nothing to try yet\n- Useful: 3\/5\n- Signal: 3\/5\n- Present in the build but not switched on"}
