Frequently asked questions
How do I get my Geetest Captcha ID and Private Key?
Sign up at Geetest Console, 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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
