Agent Scoped Tool Access Control With Permission Model

via “multi-user-secure-tool-calling-with-oauth2-scoping”

End-to-end, code-first tutorials for building production-grade GenAI agents. From prototype to enterprise deployment.

Unique: Uses ArcadeTool abstraction with auth_callback hooks to intercept and validate tool calls at invocation time, binding each call to a specific user's OAuth2 token and scope set — unlike generic function-calling systems, this enforces authorization before execution rather than relying on downstream API validation

vs others: Provides user-scoped tool calling that frameworks like LangChain's tool_choice and Anthropic's native tool_use lack; agents cannot accidentally call tools outside a user's permission set because authorization is enforced at the agent layer, not delegated to external APIs
