Frequently asked questions
Can I see exactly why a Mabl test failed using my agent?
Yes. Use the mb.get_execution tool with a specific Execution ID. Your agent will retrieve deep diagnostic information, including the failure reason, test outcomes, and visual screenshots to help you identify UI regressions instantly.
How do I trigger a specific test plan through a conversation?
The mb.trigger_plan tool allows your agent to start executions associated with a Plan ID or Label. You can also specify an optional Environment ID to target a specific stage (e.g., Staging vs Prod) for your automated tests.
Can my agent list all available testing environments in my account?
Absolutely. Use the mb.list_envs tool to identify all configured environments. Your agent will report the environment names, IDs, and any associated environment variables defined in Mabl.
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.
