Frequently asked questions
Can I use this to audit recent administrative changes in my Bitwarden organization?
Yes! Use the list_events tool to retrieve the audit trail. It provides a detailed log of events, including who performed what action and when, helping you maintain security oversight.
How do I check which security policies are currently active?
Simply ask the agent to run the list_policies action. This will return all administrative and security policies configured for your organization, such as Master Password requirements or Two-step Login rules.
Is it possible to see all the shared collections we have set up?
Yes, the list_collections tool allows you to retrieve all collections available to the organization, helping you understand how shared secrets are categorized.

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.
