satgate vs tsidp

satgate: SatGate acts as an economic firewall for AI agents, governing their API calls by enforcing scoped authority, budgets, and paid-rail context. It prevents unauthorized spending and resource invocation, integrating seamlessly with existing routing gateways and LLM providers.; tsidp: `tsidp` is an experimental OpenID Connect (OIDC) and OAuth Identity Provider that integrates with your Tailscale network, enabling applications to authenticate users using their Tailscale identities. It supports both OIDC-compatible applications and authenticated MCP client/server connections, offering flexible deployment options via Docker or direct Go execution.
