Build Logic in n8n. Manage Intelligence in AgentBrains

You love n8n for its workflow flexibility, but building a production-ready agent requires more than just logic loops. It requires structured memory, precise retrieval, and rigorous testing.

The AgentBrains Node Pack bridges the gap, giving your workflows instant access to enterprise-grade tools without complex API configurations.

Stop Hallucinations with Deterministic Retrieval

The Knowledge Base Access Node

Sometimes you don't want your agent to "search and guess." You want it to read the exact file you created.

Pin-Point Accuracy

Use simple dropdown menus to select specific Folders or Files from your AgentBrains Knowledge
Base.

Ideal Use Case

Perfect for retrieving Price Lists, Technical Data Sheets, Instruction Manuals, or strict
Company Policies.

The Output

The node returns clean, parsed Markdown or JSON directly into your workflow, ensuring the LLM receives the exact data structure it needs to answer correctly.

nfinite Long-Term Memory. Zero Setup

The Vector DB Tool Node

Turn your entire Knowledge Base into a searchable brain. This node functions as a standard AI Tool that you
can plug directly into your LangChain or AI Agent nodes within n8n.

No need to set up Pinecone, manage embeddings, or write Python scripts. Just add the node as a Tool.

When the user asks a broad question (e.g., "How do I troubleshoot the thermal sensor?"), the agent uses this tool to query your entire Knowledge Base and retrieve the most relevant context chunks.

Combine this with the Knowledge Base Access Node to give your agent both broad knowledge (Vector) and specific facts (File Retrieval).

Show, Don't Just Tell

The Image Retrieval Tool Node

Standard AI agents are stuck in a text-only world. This node breaks that barrier, allowing your n8n workflow to instantly fetch and display visual assets from your Knowledge Base.

Visual Tooling

Add this node as a Tool in your AI Agent’s toolbelt. When a user asks to see something, the agent
triggers this node.

Semantic Label Search

You don't need to know the filename. The node uses the intelligent labels generated during our ingestion process (e.g., "Wiring Diagram for Model X" or "Red vs. Blue Color Comparison") to find the exact image that matches the conversation context.

Instant Delivery

The node returns a direct, hosted URL
that renders immediately in the chat, allowing your
agent to provide visual proof, specific diagrams, or
product shots without leaving the conversation flow.

Validate Your Flows Without Rewriting Them

The QA & Testing Node

Testing agents in n8n usually means manually triggering workflows and reading JSON outputs. The AgentBrains QA Node changes the game by connecting your workflow directly to our Synthetic User engine.

Non-Intrusive

Drop this node into your existing flow. It doesn't alter your logic or change your output; it simply acts as a bridge to the AgentBrains testing environment.

Synthetic Simulation

Once connected, you can use the AgentBrains interface to spin up "Angry Customers" or "Curious Leads" that interact with your n8n workflow automatically.

Instant Scoring

Once connected, you can use the AgentBrains interface to spin up "Angry Customers" or "Curious Leads" that interact with your n8n workflow automatically.

"Http Request" vs. AgentBrains Nodes

Stop writing Python scripts to manage embeddings. AgentBrains creates a production-ready backend for you.

Auth Handling

No complex header management. API keys are handled securely in the credential store.

Context Optimization

We pre-format the data for LLMs. No need to write Javascript functions to clean up HTML or parse arrays before feeding them to the AI.

Visual Management

Select files and folders via UI dropdowns, not by hardcoding UUID strings.
