pip install microsoft-fabric-rti-mcp

Common errors

error ModuleNotFoundError: No module named 'fabric_rti_mcp' ↓

cause Package not installed or wrong environment.

fix

Run 'pip install microsoft-fabric-rti-mcp' and ensure Python version >=3.10.

error Unauthorized: request is not authorized ↓

cause Missing or expired FABRIC_USER_ACCESS_TOKEN.

fix

Set FABRIC_USER_ACCESS_TOKEN to a valid Fabric bearer token. Use 'az account get-access-token --resource https://api.fabric.microsoft.com' to obtain one.

error AttributeError: module 'fabric_rti_mcp' has no attribute 'main' ↓

cause Incorrect import path.

fix

Use 'from fabric_rti_mcp.server import main' instead of 'from fabric_rti_mcp import main'.

Warnings

breaking Authentication requires FABRIC_USER_ACCESS_TOKEN, not Microsoft Entra credentials directly. Use a short-lived bearer token. ↓

fix Set env var FABRIC_USER_ACCESS_TOKEN from Azure CLI or Fabric API.

breaking CORS origins default to localhost only; remote hosts must set FABRIC_RTI_CORS_ORIGINS. ↓

fix Set env var FABRIC_RTI_CORS_ORIGINS to a comma-separated list of allowed origins.

gotcha Security-sensitive CRP keys cannot be overridden via MCP tools. This is a security measure, not a bug. ↓

fix Configure CRP keys through environment variables, not tool calls.

deprecated The Starlark-based Kusto skill is being replaced; older versions may use deprecated skill names. ↓

fix Use the updated Kusto Copilot skill introduced in 0.5.1.
