Two tools with minimal definitions. 'add' has a clear verb-noun name and basic schema with typed parameters (a, b as numbers), but description is generic (10 chars). 'getToken' violates security best practices by exposing a bearer token as tool output, this should never be a tool. Both tools lack output schema documentation. Parameter descriptions are present but terse. No error handling guidance. No pagination, no idempotent hints, no recovery paths. Schemas are present but incomplete (no output types documented).

• Remove getToken tool entirely or redesign it to NOT return the bearer token. If the goal is to demonstrate auth, create a tool that returns a masked token or a token metadata object (expiry, scopes) instead.
• Expand 'add' description to 80 - 150 chars: 'Adds two numbers together and returns the sum. Use this for arithmetic operations. Returns a numeric result as text.'
• Document output schemas for both tools. E.g., add returns {type: 'object', properties: {result: {type: 'number'}}}.
• Add error handling: 'If inputs are not numbers, returns error: Invalid input, both a and b must be numbers.'
• Rename getToken to something more specific (e.g., 'retrieve_current_bearer_token') and add a description explaining it is for demonstration only and should never be used in production.
