Perplexity

Chain together database operations

Stop manual data entry and let your agent handle record updates. You can trigger `create_database_row` based on the output of previous chain links, ensuring your information stays synced without you touching a keyboard. This MCP Server allows your agent to fetch schema details using `get_database` before executing logic. It creates a predictable flow where each step relies on accurate, real-time data from your workspace.

Automate page content cycles

Your agent can now read and modify your documentation on the fly. By using `list_pages` followed by `get_page`, the agent builds a map of your current knowledge base to identify exactly what needs a refresh. Once the agent identifies the right spot, it uses `update_page` to commit changes. This removes the friction of jumping between your code and your project management tool.

Query workspace knowledge instantly

Connect your agent to your entire database via `query_database` to pull specific records into your chains. It turns your workspace into a live data source that your agent can filter and sort programmatically. When you need to know who is working on what, `list_users` provides the necessary context for your agent. It makes your LangChain pipelines aware of the people involved in your projects.

Setup guide

Set up FlowUs MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes FlowUs tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "flowus-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent FlowUs transactions"
    })
    print(result["messages"][-1].content)

Common questions about FlowUs MCP in LangChain

You need to provide your endpoint token to the Vinkius-managed server. Once configured, your LangChain agent initializes the connection and starts executing tools immediately.

Yes. The MCP protocol treats each tool output as a potential input for the next step. You can take the result from `list_blocks` and feed it directly into a prompt for your agent.

It does. You pass the server tools into your agent constructor and let the model decide when to call them. The agent handles the tool invocation based on the task you assign.

Vinkius handles authentication through a single endpoint token. Your data stays within the encrypted transport layer, and your agent only accesses what you explicitly authorize.

The server returns a standard error code that your chain can catch. You can then program your agent to retry or notify you of the specific failure.
