n8n-nodes-azure-cohere-reranker

This is an n8n community node package that adds Azure-hosted Cohere reranking support for AI workflows.

It provides:

• Azure Cohere Reranker (AI Reranker node)
• Azure Cohere Rerank API (credential)

This node is useful when you want to rerank retrieved documents using Azure AI Foundry-hosted Cohere models (for example, rerank-v3.5) before passing context to an AI Agent.

n8n is a fair-code workflow automation platform.

Installation

From n8n UI (after npm publish)

1. Go to Settings -> Community Nodes.
2. Install package: n8n-nodes-azure-cohere-reranker.

Manual install (self-hosted)

Use this for Docker/air-gapped/private installs.

npm i n8n-nodes-azure-cohere-reranker

For Docker/manual install details, see n8n docs:

• https://docs.n8n.io/integrations/community-nodes/installation/manual-install/

Nodes

Azure Cohere Reranker

AI Reranker node that reorders candidate documents by relevance to a query.

Parameters:

• Model: Azure Cohere rerank model/deployment name (default: rerank-v3.5)
• Top N: Maximum documents to return after reranking

Credentials

Azure Cohere Rerank API

Required fields:

• API Key
• Base URL

Supported Base URL formats:

• https://<resource>.services.ai.azure.com
• https://<resource>.services.ai.azure.com/providers/cohere
• https://<resource>.services.ai.azure.com/providers/cohere/v2/rerank

The credential test automatically normalizes these URL variants.

Usage

Typical RAG flow in n8n:

1. Retrieve candidate documents (for example from a vector store).
2. Connect Azure Cohere Reranker to the retriever reranker input.
3. Provide Azure Cohere credential, model, and top-N value.
4. Pass reranked results to your AI Agent / LLM chain.

Compatibility

• Package type: n8n community node
• Tested on: n8n 2.17.5
• Requires self-hosted n8n with community packages enabled.

Troubleshooting

• If the node does not appear, verify community packages are enabled and restart n8n.
• If credential test fails, validate API key, base URL, and Azure resource access to Cohere models.
• For Docker, ensure package is installed in ~/.n8n/nodes for the running container user.
