description	Add ADK-Rust tools, MCP integrations, and ADK UI protocol outputs safely. Use when building function tools, MCP toolsets, browser tools, or UI render tools.

ADK Rust Tools MCP UI

Overview

Implement tools with strict schema contracts and protocol-aware outputs.

Workflow

1. Start with FunctionTool and explicit JSON schema.
2. Add MCP toolsets with auth/reconnect configuration.
3. Add ADK UI render tools with protocol compatibility checks.
4. Validate tool protocol outputs with existing test matrices.
5. Use MCP Resource API (list_resources, list_resource_templates, read_resource) for server-provided data.
6. Use ElicitationHandler for MCP servers that request user input during tool execution.

Guardrails

1. Reject ambiguous argument schemas.
2. Preserve protocol behavior for legacy and MCP Apps compatibility.
3. Add tests for invalid inputs and auth failures.
