How do I get my Geetest Captcha ID and Private Key?

Sign up at [Geetest Console](https://www.geetest.com/), create a new CAPTCHA project, and find your Captcha ID and Private Key in the project settings.

What's the difference between validate_captcha and validate_with_risk?

validate_captcha checks only the CAPTCHA completion. validate_with_risk also analyzes the user's IP address and behavior patterns for more accurate bot detection.

How does Geetest detect bots?

Geetest v4 uses behavioral analysis, mouse movement patterns, touch events, and environmental fingerprints to distinguish humans from automated scripts — without requiring users to solve puzzles.

Why Use Google ADK with the Geetest MCP Server

Google ADK provides unique advantages when paired with Geetest through the Model Context Protocol.

Google ADK natively supports MCP tool servers — declare a tool provider and the framework handles discovery, validation, and execution

Built on Gemini models, ADK provides long-context reasoning ideal for complex multi-tool workflows with Geetest

Production-ready features like session management, evaluation, and deployment come built-in — not bolted on

Seamless integration with Google Cloud services means you can combine Geetest tools with BigQuery, Vertex AI, and Cloud Functions

Geetest + Google ADK Use Cases

Practical scenarios where Google ADK combined with the Geetest MCP Server delivers measurable value.

Enterprise data agents: ADK agents query Geetest and cross-reference results with internal databases for comprehensive analysis

Multi-modal workflows: combine Geetest tool responses with Gemini's vision and language capabilities in a single agent

Automated compliance checks: schedule ADK agents to query Geetest regularly and flag policy violations or configuration drift

Internal tool platforms: build self-service agent platforms where teams connect their own MCP servers including Geetest

Geetest + Google ADK FAQ

Common questions about integrating Geetest MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
