Frequently asked questions
How do I securely obtain my API Key?
Installation in Pumble is unique. In your workspace, click + Add apps in the left sidebar, find the API addon, and install it. After doing so, go to any chat input box in Pumble and type /api-keys generate. A private, ephemeral message will appear containing your secret token. Paste that token here.
Can my AI automatically reply to unread issues?
Yes. You can instruct your agent to regularly fetch messages from a specific channel (chat_history_messages). The agent can evaluate questions, generate answers based on your knowledge base, and then use chat_post_message to post the solution back to the team instantly.
Is it possible for the AI to react with emojis?
Absolutely. It uses the chat_add_reaction functionality. A common use case is having the agent process a batch of tickets reported in Pumble, and instruct it to leave a '✅' checkmark reaction on the original message to signify that work is complete.
What happens if a bot message has a typo?
Unlike standard webhooks, this integration provides full bidirectional control. If your AI posted something incorrect, simply ask it to update its previous message. It will fetch its message ID and push a new payload using the chat_update_message tool instantly without leaving double messages.
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.
