Chain Dastra privacy tasks in LangChain

Connect your agents to your Dastra workspace to automate complex compliance workflows. You can trigger `create_dsr` to initiate a request, then pass the result directly into a chain for validation. This MCP Server lets your agent handle the entire lifecycle of a request without you manually checking the dashboard. Each tool output flows perfectly into the next link of your LangGraph sequence.

Audit processing activities with LangChain

Query your data mapping records by calling `list_processings` to feed your agent live context. It parses your ROPA data to answer questions about specific data flows during a conversation. Everything stays tracked in LangSmith so you see exactly how the agent interpreted the privacy data. You stop guessing why a compliance decision was made.

Manage data breach reporting automatically

Use `create_breach` to log incidents as soon as your monitoring agent detects an anomaly. It writes the record directly to Dastra, ensuring you never miss a notification deadline. Your agent checks existing records with `list_breaches` before acting. This prevents duplicate entries and keeps your logs clean.

Setup guide

Set up Dastra 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 Dastra 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({
    "dastra-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 Dastra transactions"
    })
    print(result["messages"][-1].content)

Common questions about Dastra MCP in LangChain

Install the MCP adapters via pip. Use the MultiServerMCPClient to point at your Vinkius endpoint, then pass the tool list into your LangChain agent constructor.

Yes, it treats Dastra tools as standard chain functions. You map the output of one tool to the input of another for complex workflows.

It does. You call the listing tools to get your processing activities into your agent's context window for analysis.

It is stateless by default. Use a session client if you need persistent context for your agents.

Dastra only exposes the specific breach records and DSR metadata you request. We secure the connection via your unique endpoint token.
