Sequence generation for LangChain agents

The `generate_bates_numbers` tool forces your agent to produce strict, sequential indices for legal files. You get a reliable array of strings that never skips a beat. LangChain chains rely on this predictability. By piping the tool output directly into your document processing node, you ensure every page receives a unique, audit-ready identifier without manual oversight.

Tracing your document numbering

LangSmith logs every input and output for the Bates Numbering Generator Engine in real-time. You can spot exactly where a sequence starts or if a batch size exceeds your document count. Watching the tool execute inside a ReAct loop gives you total visibility. Debugging complex document workflows becomes a matter of checking the trace for the expected string format.

Managing MCP server state

Maintain persistent document context across your chain using the client session. This MCP server handles the heavy lifting of incrementing your indices while you focus on the document retrieval logic. Your agent keeps the state clean. When the chain finishes, you have a perfectly indexed list of files ready for legal submission.

Setup guide

Set up Bates Numbering Generator Engine 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 Bates Numbering Generator Engine 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({
    "bates-numbering-generator-engine-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 Bates Numbering Generator Engine transactions"
    })
    print(result["messages"][-1].content)

Common questions about Bates Numbering Generator Engine MCP in LangChain

Install the MCP adapters and point your client at the Vinkius endpoint. Pass the tools directly into your agent constructor to let the model invoke the sequence generator.

Yes, it creates sequences in memory without overhead. The engine returns the full array of formatted numbers instantly, keeping your agent logic snappy.

The tool outputs standard string arrays that map directly to document metadata fields. You can loop through the results and assign them to your file objects immediately.

No, it is stateless. You provide the starting index and the count, and it returns the calculated array.

This server only processes integer indices and string prefixes. It never touches the actual content of your legal documents, ensuring your raw text stays off our servers.
