      "Excerpt": "## Environment\n\n- metro-mcp: latest (npx -y metro-mcp)\n- React Native 0.81.6, Hermes engine, **legacy bridge (old arch)**\n- MCP client: Claude Code (multiple windows via SSE / supergateway)\n\n---\n\n## Problem\n\nmetro-mcp creates a single MCP `Server` instance and calls `.connect(transport)` once at startup. The MCP SDK `Server` class does not allow a second `.connect()` call, so connecting more than one AI window fails in two different ways depending on the transport:\n\n**With SSE transport…",

On a 3x iOS simulator that is 584K–2M characters, which is over the\nresponse limit of every MCP client I have tried, so the tool is effectively unusable —\nit never fails, it just always overflows.\n\nTwo separate problems: the payload is not an MCP image content block, and there is no\nway to ask for a smaller image.\n\n## Environment\n\n| | |\n|---|---|\n| metro-mcp | 0.13.2 |\n| React…",

      "Excerpt": "## Summary\n\nOn a real-world Expo Router app, every fiber-walking read tool stops at the navigator\nproviders and never reaches screen content. They return **empty results rather than an\nerror**, so an agent reads them as \"the element isn't there\" instead of \"the traversal\ndidn't get that far\".\n\n`tap_element` is unaffected — it uses a different search path and finds the same\nelements the read tools claim don't exist. That asymmetry is the clearest proof the\nelements are present and reachable.\n\n##…",
