Why MCP Dataverse?

AI agents hallucinate schema, guess column names, and build broken OData queries. This server gives them real-time access to your Dataverse environment — schema, records, metadata, solutions — through the Model Context Protocol.

• Three auth modes — device code (local), client credentials (CI/CD), managed identity (Azure-hosted)
• Works with any MCP client — VS Code, Claude, Cursor, Windsurf, Gemini, Codex CLI
• Atomic tools — each tool does one thing well; the AI picks the right one
• Structured outputs — every response returns {summary, data, suggestions}
• Guardrails — destructive operations require explicit confirmation
• Encrypted tokens — AES-256-GCM cached credentials, never logged

Install

npx mcp-dataverse install

The interactive wizard configures your environment, registers the server in VS Code, and authenticates your Microsoft account in under 2 minutes.

Requires Node.js 20+. For other clients (Claude, Cursor, Windsurf…) see Multi-Client Setup.

Authentication

Three modes — choose based on where the server runs:

| Mode | When to use | |:-----|:------------| | Device Code (default) | Local development — interactive Microsoft login, token cached on disk | | Client Credentials | Unattended: CI/CD, Docker, Azure services — authMethod: "client-credentials" + App Registration | | Managed Identity | Azure-hosted (App Service, Container Apps) — zero secrets, authMethod: "managed-identity" |

Device code quick start: authentication triggers on the first tool call.

1. Open View → Output → MCP — a sign-in code appears
2. Go to https://microsoft.com/devicelogin, enter the code, sign in with your work account
3. Token is cached encrypted — all future starts are silent

For client credentials and managed identity setup, see Authentication docs.

HTTP Transport

Run as an HTTP server for multi-client use:

MCP_TRANSPORT=http MCP_HTTP_PORT=3000 MCP_HTTP_SECRET=mysecret node dist/server.js

Connect using VS Code / Copilot with:

{
  "servers": {
    "dataverse": {
      "type": "http",
      "url": "http://localhost:3000/mcp",
      "headers": {
        "Authorization": "Bearer mysecret"
      }
    }
  }
}

Troubleshooting

| Symptom | Fix | | ---------------------------------- | ------------------------------------------------------------------ | | No sign-in prompt | Open View → Output → MCP — the device code is displayed there | | No MSAL accounts found | Run npx mcp-dataverse-auth then restart the server | | Authentication timed out | Restart the MCP server — a fresh code is generated automatically | | Server not appearing in Agent mode | Run npx mcp-dataverse install or npx mcp-dataverse doctor | | HTTP errors | Run npx mcp-dataverse doctor to diagnose config and connectivity |

Performance Tip

MCP Dataverse is designed to be comprehensive, but most AI models work best with fewer tools in context. Deselect the tools you don't need in your client's tool picker (e.g. VS Code Chat panel) to keep the agent focused and responsive.
