n8n Intelligent Query Orchestrator: Query Any Data

This n8n workflow acts as an intelligent orchestrator for querying various data sources using AI agents. It leverages large language models (LLMs) and custom tools to interpret user queries, determine the best way to fetch the requested data, and return a structured response.

What it does

This workflow simplifies complex data querying by:

  1. Receiving Chat Messages: It starts by listening for incoming chat messages, which represent user queries for data.
  2. Preparing the AI Agent: It then sets up an AI Agent, configuring it with a specific task and providing it with a "Call n8n Workflow Tool."
  3. Intelligent Query Execution: The AI Agent, powered by a selected Chat Model (Anthropic or Google Gemini), uses the provided tool to intelligently process the user's query. It determines if it needs to call another n8n workflow to fetch the data.
  4. Structured Output: After the AI Agent processes the query and potentially retrieves data, the workflow uses a Structured Output Parser to ensure the final response is in a consistent, usable format.
  5. Aggregating and Limiting Data: It includes steps to aggregate and limit the output, ensuring that the final data presented is concise and relevant.
  6. Responding to the User: The processed and structured data is then prepared for a response, likely back to the chat interface or another system.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • AI Credentials:
    • Anthropic API Key OR
    • Google Gemini API Key
    • These are required for the "Anthropic Chat Model" and "Google Gemini Chat Model" nodes, respectively. You will need to configure credentials for at least one of these.
  • Another n8n Workflow (for the "Call n8n Workflow Tool"): This workflow is designed to orchestrate queries. The "Call n8n Workflow Tool" implies that there's at least one other n8n workflow that this agent can call to actually perform data fetching from specific sources (e.g., Google Sheets, databases, APIs). You will need to specify the workflow ID and potentially parameters for these linked workflows.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure AI Credentials:
    • Open the "Anthropic Chat Model" or "Google Gemini Chat Model" node.
    • Select or create a new credential for your chosen AI provider (Anthropic or Google Gemini) and enter your API key.
  3. Configure the "Call n8n Workflow Tool":
    • Open the "Call n8n Workflow Tool" node.
    • Specify the Workflow ID of the n8n workflow(s) that this agent should be able to call to retrieve data.
    • Define the Description for each tool, explaining what kind of data it can fetch. This description is crucial for the AI Agent to understand when to use the tool.
  4. Activate the Workflow: Once configured, activate the workflow.
  5. Send a Chat Message: Send a chat message to the "When chat message received" trigger. The AI Agent will then process your query and attempt to fetch the requested data using its configured tools.

This workflow provides a powerful foundation for building intelligent, natural language interfaces to query diverse data sources within your n8n ecosystem.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
