Viio MCP Server

The Viio MCP Server connects Claude, ChatGPT, Cursor, Microsoft Copilot, and other AI assistants or workflow builders to your Viio workspace. Use it to analyze your SaaS stack, generate reports, prepare renewals, and find optimization opportunities from structured Viio data.

What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI assistants access external tools and data sources. Instead of copying data into prompts, MCP gives the AI direct, structured access to your systems.

What the Viio MCP Server Does

The Viio MCP Server exposes specialized tools that AI assistants can call to analyze your SaaS portfolio. These tools cover:

• Cost optimization — Find savings opportunities, wasted licenses, and overprovisioned apps
• Renewal management — Get renewal briefs, seat recommendations, and negotiation leverage data
• Usage analysis — Identify low-adoption apps, unused licenses, and leavers with active licenses
• Application insights — Get detailed app data, license plans, and category breakdowns

The server uses Streamable HTTP transport and supports two authentication methods:

• OAuth with Client ID Metadata Documents (CIMD) — For AI clients that support browser-based authorization with CIMD. No API key is needed.
• API key — For developer tools and programmatic access. Requires a Viio API key.

Why Viio Uses CIMD

To better protect customer data, Viio no longer supports OAuth Dynamic Client Registration (DCR). OAuth connections now use Client ID Metadata Documents (CIMD) instead.

CIMD allows the Viio identity server to retrieve and validate an MCP client's identity, redirect URIs, and other OAuth metadata from a stable HTTPS document. This avoids accepting arbitrary client-registration requests and gives Viio tighter control over which clients can request access to customer data.

Your MCP client must support OAuth with CIMD. If it does not, you can still connect securely by creating a Viio API key and sending it as the Authorization header:

Authorization: YOUR_API_KEY

How It Works

1. You configure your AI assistant to connect to the Viio MCP Server.
2. The AI assistant discovers the available tools automatically.
3. When you ask a question about your SaaS portfolio, the AI calls the appropriate tools.
4. The server queries your Viio workspace data and returns structured results.
5. The AI interprets the data and provides actionable recommendations.

Example Conversation

You: What are our biggest cost-saving opportunities?

AI: Let me check your savings opportunities...

The AI calls the "Get Savings Opportunities" tool, then interprets the results:

You have 3 significant opportunities:

1. Slack — 45 unused licenses ($12,600/yr potential savings)
2. Figma — 28 unused licenses ($8,400/yr potential savings)
3. Zoom — Enterprise licenses downgradable to Pro ($15,000/yr potential savings)
