FastMCP Server in Python: Auth, Permissions, and Secure Tools

Secure tool server: build a minimal, auditable flow to authenticate users, enforce scopes, sandbox paths, and cap costs for safe remote tool calls. Practical Python demo showing token signing and verification with hmac and hashlib, scope checks, a path-prefix sandbox, and a per-user credit budget. Tie these guards together to run guarded tools that only access allowed files and stop runaway costs.
