- Add langchain-mcp-adapters dependency - New app/tools/mcp_jina.py: Jina MCP client with filtered tool loading (search_web, read_url, sort_by_relevance) - Update resolve_tools to return (tools, needs_jina_mcp) tuple - Update builder.py: skip graph cache for MCP-bound tools, add search tool guidance to system prompt - Refactor chat.py: extract _run_graph_stream, add MCP/non-MCP paths, update tool titles and summaries for MCP tool names - Tested locally: both MCP search path and non-MCP knowledge path work Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
