Frequently asked questions
Can I create a certificate and send it to someone in one workflow?
Yes! First use create_credential with the recipient details and template ID, then issue_credential to make it official, and finally send_credential to deliver it via email.
How do I find the right template ID to use when creating a credential?
Use the list_credential_templates tool to browse all available templates. Each template includes its ID, name, and description. Copy the ID and use it in the create_credential tool.
Can I search for a credential by the recipient's email address?
Absolutely. Use the search_credentials tool and enter the recipient's email as the query. It will return all credentials matching that email address.
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.
