MCP365 Explorer

Compatibility

Summary

Open-source SPFx webparts for exploring Microsoft 365's MCP and Foundry surface. Two patterns:

• Work IQ MCP servers, called directly from an SPFx webpart — no backend, no proxy, just fetch + AadTokenProvider + JSON-RPC. One webpart per server.
• Microsoft Foundry behind a protected Function App — keyless backend, Easy Auth + managed identity, deployed in one command via spfx-foundry-deploy. Starts with mcp365-foundry-chat (chat-only showcase).

Each webpart pairs with a blog post.

Preview notice: The Agents 365 Tools and MCP servers are part of the Microsoft Agent 365 tooling servers preview. These features are in preview, may change, and should not be used in production workloads.

What Each Webpart Does

• Showcase mode — click a button, see the result. No JSON, no parameters.
• Explorer mode — browse tools, inspect live schemas from tools/list, auto-generated parameter forms, formatted responses, searchable log viewer
• Custom presets — save your own parameter sets to browser localStorage

Prerequisites

For the Work IQ webparts:

1. Microsoft Frontier AI Program — Enrollment
2. Work IQ Tools Service Principal — Run New-Agent365ServicePrincipal.ps1 (one-time admin operation). See Microsoft's guide.
3. Power Platform Environment ID — From Power Platform admin center. See how to find it.
4. Node.js 22+ and SPFx 1.22

For the Foundry-backed webparts — additionally:

5. Azure subscription with quota for gpt-5-mini (or your chosen model) in the target region
6. Azure CLI ≥ 2.69 and Azure Functions Core Tools v4 (func) — both pre-installed in the included Codespaces devcontainer

Note on service principal naming: These webparts use "resource": "Work IQ Tools" in package-solution.json. If you ran the service principal script before March 12, 2026, your enterprise app is named "Agent 365 Tools" instead. In that case, change "resource": "Work IQ Tools" to "resource": "Agent 365 Tools" in each webpart's config/package-solution.json — otherwise the SharePoint admin center will reject the API permission request.

Quick Start

User Profile (5 tools)

cd webparts/mcp365-user-profile
npm install
npx heft build --clean
npx heft test --clean --production && npx heft package-solution --production

Upload .sppkg, approve McpServers.Me.All, add to a page.

SharePoint (35 tools)

cd webparts/mcp365-sharepoint-lists
npm install
npx heft build --clean
npx heft test --clean --production && npx heft package-solution --production

Upload .sppkg, approve McpServers.SharePoint.All, add to a page.

Foundry chat showcase

cd webparts/mcp365-foundry-chat
npm install
npm run deploy        # provisions the proxy + auto-wires serve.json (~5 min)
npm start             # workbench opens with the property pane pre-filled

npm run deploy walks you through a one-screen review form (region, model, prefix), then provisions everything: AI Foundry resource + model deployment, Storage Account, Function App with managed identity, Backend API Entra app, Easy Auth, platform hardening, App Insights. No function key in the browser. Full breakdown at spfx-foundry-deploy.

npm run teardown removes everything — resource group, soft-delete purge, Entra app — so you can experiment without lingering infra.
