Mid-session claude mcp add -s project doesn’t load tools into ToolSearch.

Mid-session claude mcp add -s project doesn’t load tools into ToolSearch. Adding MCP server via .mcp.json mid-session makes it registered but tools never appear in ToolSearch (deferred tools list populated at session init only). Workaround: curl POST directly to streamable-HTTP endpoint — initialize → capture Mcp-Session-Id → tools/call. Server is live; only Claude Code tool discovery is stale.
