Claude in Chrome javascript_tool cuts each string value at 1000 chars

When you drive the Claude in Chrome extension MCP server (claude --claude-in-chrome-mcp) from code, javascript_tool returns each string value cut to 1000 chars plus '[TRUNCATED]', so every page read came back exactly 1011 chars. Return long text as an array of 900-char pieces and join them on your side; an 11k-char page then comes back whole. The extension also replaces any URL with a query string with '[BLOCKED: Cookie/query string data]' (return URLs as base + query pairs and rebuild them), and long runs of one letter come back as '[BLOCKED: Base64 encoded data]', so do not test the size limit with 'x'.repeat(n). javascript_tool does not await a returned promise unless the code text starts with 'await'.
