Bringing AI Intelligence into Integration Flows
The next era of integration is here — powered by Artificial Intelligence (AI).
The MuleSoft AI Chain Connector (MAC Connector) enables developers to design, manage, and deploy AI-driven integration workflows directly within Anypoint Platform.
Built on the LangChain4j framework, it orchestrates seamless interaction between:
- Large Language Models (LLMs)
- Vector Databases
- External AI Services
—all with minimal coding effort and complete flexibility.
What is the MuleSoft AI Chain Connector?
The MuleSoft AI Chain Connector (MAC Connector) is an open-source MuleSoft connector that allows developers to design, manage, and deploy AI agents directly within Anypoint Platform.
Built on the LangChain4j framework, it orchestrates interactions between:
- Large Language Models (LLMs)
- Vector databases
- External AI services
…all with minimal coding effort.
Key Features MuleSoft AI chain Connector

Embeddings & Vector Stores | Perform semantic searches and retrieve context-rich data efficiently. |
Image Generation & Analysis | Generate, analyse, or transform images using AI capabilities. |
Sentiment Analysis | Understand user sentiment and extract actionable insights. |
Tool Integration | Extend AI capabilities by integrating APIs or external services as tools. |
Use the Connector in Your Project:
Once the connector dependency is added to your project in the pom, or we can take it from the exchange. Here’s how:
Choose the LLM Provider
The connector supports multiple LLM types — for example:
- Anthropi
- Azure OpenAI
- Mistral AI
- Hugging Face
- Ollama
- OpenAI
- GroqAI
- Google Gemini
The MuleSoft AI Chain Connector supports two configuration methods:
A) Environment Variables – Set the required LLM environment variables in your Mule runtime OS. Enter – in the File Path field.
Environment Variables by LLM Type
Based on the LLM Type, you need to set different environment variables. Here is a list of all environmental variables based on the currently supported LLM Types:
B) Configuration JSON – When choosing the Configuration JSON option, you must provide the dedicated configuration JSON file path that includes all required properties.
You can use a DataWeave expression to store this JSON configuration in the resources folder of your Mule application.
DW Expression:
mule.home ++ “/apps/” ++ app.name ++ “/envVars.json”
Configuration JSON File Example
https://mac-project.ai/docs/mulechain-ai/getting-started#configuration-json-file-example
This is an example of the configuration JSON file. Ensure that you fill out the required properties for your LLM type. The file can be stored externally or added directly to the Mule application in the src/primary/resources folder.
Note: The API token must be generated and placed correctly based on your configuration type.
Example (for OpenAI): If using Environment Variables, use the API from the Platform. Once generated, set it in your MuleSoft Studio environment.
This enables the MuleSoft AI Chain connector to authenticate and interact securely with OpenAI services.
Model Name
https://mac-project.ai/docs/mulechain-ai/getting-started
After choosing the LLM provider, the available and supported models are listed in the model’s name dropdown
- Temperature: Controls output randomness (0–2, default 0.7).
- Timeout: Max wait time in seconds (default 60).
Max Token: Limits the number of tokens to control cost.
Supported Operations
The connector supports 15 operations grouped across categories (Agent, Chat, Embeddings, Image, RAG, Sentiment, Tools).
Feature | Description |
Multi-LLM Support | Connect with OpenAI, Azure OpenAI, Anthropic, and more. |
Retrieval-Augmented Generation (RAG) | Use external knowledge to improve AI responses. |
Embeddings & Vector Stores | Efficient semantic search and data retrieval. |
Image Generation & Analysis | Generate and analyse images via AI. |
Sentiment Analysis | Understand customer feedback and insights. |
Tool Integration | Extend AI agent capabilities with external tools. |
