Chain compliance checks in LangChain

LangChain agents can coordinate multi-step workflows to keep your UK entities compliant via Inform Direct. Your agent triggers `get_filing_status` to pull upcoming deadlines, evaluates the results, and then calls `list_filings` to verify what actually went through. This LangChain compliance sequence runs autonomously without you needing to log into the Companies House portal manually. Every tool execution, from `list_companies` to `get_company`, is tracked in LangSmith so you can audit the exact inputs and outputs.

Automated onboarding pipelines with this MCP Server

Build ingestion pipelines that add new UK entities to your Inform Direct dashboard instantly using LangChain. The agent uses `add_company` to register the firm, then immediately invokes `list_directors` to pull the active leadership team into your local database. Using the LangChain MCP adapter means these actions happen in a single, observable execution graph. You don't write custom integration code for each endpoint, as the LangChain agent resolves dependencies between the Inform Direct tools on the fly.

Offboard entities and clean up records

Manage your entity list dynamically when clients offboard from your LangChain-driven compliance service. The agent runs `remove_company` to clean up the local Inform Direct dashboard, which keeps your active list focused on current clients. Because this action does not affect the official records at Companies House, your LangChain workflow remains safe from accidental legal deletions. The agent checks the status using `check_informdirect_status` before running any MCP commands in your LangChain pipeline.

Setup guide

Set up Inform Direct 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 Inform Direct 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({
    "inform-direct-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 Inform Direct transactions"
    })
    print(result["messages"][-1].content)

Common questions about Inform Direct MCP in LangChain

Install the LangChain MCP adapter package first. Instantiate the client using the Vinkius HTTP transport URL, call the MCP tool registration method, and pass those tools directly to your agent.

Yes. Your agent can loop through a list of entities, calling `list_companies` and then querying `get_company` for each ID to compile a master report.

LangChain handles this through standard runnable configs or custom backoff wrappers. If `get_filing_status` hits a limit, the chain pauses and retries based on your policy.

Every call to `list_shareholders` or `get_account` is logged in detail. You see the exact payload sent to the API and the raw response, making debugging straightforward.

Vinkius runs the MCP server in an isolated sandbox, meaning your UK company filings and director details are never exposed to the public internet. Communication between LangChain and the API uses single-token authentication, keeping sensitive corporate records locked down.
