Add `mcpServers` to ChatConfig and expose `chat.mcp` with `listTools()`, `callTool()`, and `refresh()` methods. Supports SSE and Streamable HTTP transports with static or dynamic auth headers. Uses dynamic imports so users who don't configure MCP pay zero cost. Failed server connections log warnings and don't block initialization. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add McpCallToolOptions with per-call headers override for per-user/per-tenant auth scenarios. When headers are provided, a temporary client+transport is created for the duration of the call. Also adds MCP feature docs and API reference updates. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
