Adds the ability to connect the agent to MCP servers and expose their tools alongside the built-in Office/bash tools. - sdk/mcp: minimal Streamable HTTP MCP client (initialize, tools/list, tools/call with SSE parsing + session handling), config load/save in localStorage (`<prefix>-mcp-config`), and loadMcpTools() which wraps each server's tools as AgentTools (named `<server>_<tool>`). - runtime: load MCP tools during init() before the agent is built, merge them into the tool list, and expose reloadMcpTools(). - core: ChatController.reloadMcpTools() passthrough and a "MCP servers" section in the settings panel (add/remove/enable servers, save & reload). No secrets are stored in code — server URLs live in localStorage like provider config. For an http:// MCP server behind the browser, point the configured URL at a localhost proxy (Chromium allows https->http://localhost). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What
Adds Model Context Protocol (MCP) support so the agent can connect to MCP servers and use their tools alongside the built-in Office/bash tools.
Why
MCP is becoming a common way to expose tools/data to agents (databases, internal APIs, etc.). This lets an Office Agent reach those without hard-coding app-specific tools.
Changes
packages/sdk/src/mcp/(new): a minimal, browser-only Streamable HTTP MCP client —initialize,notifications/initialized,tools/list,tools/callwith SSE parsing andmcp-session-idhandling. PlusloadMcpConfig/saveMcpConfig(localStorage) andloadMcpTools()which wraps each enabled server's tools asAgentTools (named<server>_<tool>). A failing server is logged and skipped — never throws.runtime.ts: loads MCP tools duringinit()before the agent is built (so they're included), merges them into thetoolsgetter, and addsreloadMcpTools().core:ChatController.reloadMcpTools()passthrough and a new "MCP servers" section in the settings panel (add/remove/enable servers, Save & Reload).Notes
localStorage(<prefix>-mcp-config), same as provider config.http://MCP server is blocked by the browser except onlocalhost. For a remotehttp://server, point the configured URL at a local proxy (or serve the MCP endpoint over HTTPS).strictis left off, so tool JSON Schemas are passed through as-is; existing Office tools are unaffected (verified: Office + MCP tools coexist and the model picks the right one).tscpasses for@office-agents/sdk;svelte-checkpasses for@office-agents/core.Testing
Verified end-to-end against a FastMCP
mssql-mcpserver (via a localhost proxy): tools load into the agent and are callable from Excel/PowerPoint/Word.🤖 Generated with Claude Code
