Single tool with minimal definition quality. The tool 'get_secure_hello' has a trivial description ('Returns a secure hello message'), empty input schema ({}), and no parameter descriptions. Description under 20 chars is weak but present (~31 chars) → description score capped at 40. Tool name follows verb convention (get_*) but the tool itself is a placeholder demo with no production utility. No error handling, no output schema documentation, no parameter guidance. The server appears to be a proof-of-concept for Azure OAuth integration, not a functional MCP tool set.

• Add a proper input schema with typed parameters (even if currently none; define it as `properties: {}, required: []` with a clear statement 'This tool accepts no parameters')
• Expand description to 80-150 characters explaining: 'Retrieves a secure authenticated greeting. Requires successful Azure OAuth authentication. Returns a greeting message confirming the user's authenticated identity. Use this to verify secure endpoint access.'
• Document the output schema: specify that the response is an object with fields like `message` (string) and optionally `authenticated_user` (string), `timestamp` (ISO 8601 string)
• Add error handling documentation: 'Returns 401 Unauthorized if OAuth token is invalid or expired. Returns 500 if backend service is unavailable. Retry on 500; request new OAuth token on 401.'
• Replace this demo tool with real MCP tools that provide business value: e.g., `get_authenticated_user_info` (returns user details from Azure AD), `validate_oauth_token` (checks token validity and remaining TTL), `refresh_oauth_token` (requests a new token)
