Bring Llm Workflows
to LangChain
Learn how to connect FlowiseAI to LangChain and start using 12 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the FlowiseAI MCP Server?
Connect your FlowiseAI (self-hosted) instance to any AI agent and take full control of your LLM orchestration and RAG workflows through natural conversation.
What you can do
- Prediction Orchestration — Trigger specific chatflows and retrieve LLM-generated responses programmatically using natural language inputs
- Chatflow Management — List all orchestration flows and retrieve detailed technical structures and metadata to monitor your AI agents
- Vector Intelligence — Programmatically upsert documents or raw data into the vector stores linked to your chatflows to ensure high-fidelity context
- Component Oversight — Access server-wide credentials, custom tools, and global variables to manage your complete Flowise ecosystem
- Operational Visibility — Monitor user feedback, leads, and assistant profiles directly through your agent for instant reporting
How it works
1. Subscribe to this server
2. Enter your Flowise Instance URL and API Key
3. Start orchestrating your LLM flows from Claude, Cursor, or any MCP client
No more manual testing in the Flowise UI for every prediction. Your AI acts as your dedicated LLM operations and orchestration coordinator.
Who is this for?
- AI Developers — instantly test and trigger complex orchestration flows using natural language queries
- Data Engineers — automate document ingestion into vector stores without leaving your workspace
- Product Managers — monitor chatflow performance and review captured leads through simple AI commands

How Vinkius secures
FlowiseAI for LangChain
Every tool call from LangChain to the FlowiseAI MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How do I find my API Key in Flowise?
Log in to your Flowise dashboard and click on the API Keys tab in the sidebar to generate or copy your unique token.
Does this support multi-tenant instances?
Yes! Ensure you provide the full Instance URL and the API Key corresponding to the specific environment you want to manage.
Can I push documents to vector stores via AI?
Absolutely. Use the upsert_vector_data tool by providing the chatflow_id and the JSON payload containing your document data.
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.
