Canvas LMS MCP server

Could not establish a plain stdio MCP session for target `canvas-server`. Command: npx -y canvas-mcp-server Diagnosis: The process exited or detached before MCP initialization completed. Raw error: MCP error -32000: Connection closed Likely causes: - The package may expect extra startup arguments or environment variables. - The package may not behave like a plain local-process stdio target under this invocation. - The server may be crashing immediately and only leaving clues on stderr. Next steps: - Run the command manually and look for usage output, auth prompts, or crash text. - Check whether the package expects a different transport or an app-oriented startup flow. - Use the recent stderr lines below before assuming this is a harness bug. Recent stderr: - Loaded environment from: .env - Missing required environment variables: - - CANVAS_API_TOKEN: Your Canvas API token - - CANVAS_DOMAIN: Your Canvas domain (e.g., school.instructure.com)
