Frequently asked questions
Can I check if a document has been signed using the agent?
Yes! Use the get_envelope_status tool with the Envelope ID. Your agent will fetch the current status (e.g., 'Completed' or 'Sent') directly from BunnyDoc.
How do I send a signature request to multiple recipients?
Simply ask the agent to create_signature_request and provide the Template ID and a JSON array of recipients. Each object should include the recipient's name and email.
Does the integration allow listing all available templates?
Yes. Use the list_templates tool. It will retrieve all the document templates configured in your BunnyDoc account, making it easy to find the ID you need for a new request.
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.
