How to Use the Dalil AI MCP in LangChain

Q: Can I trace Dalil AI tool latency using LangSmith?

Yes, every call to tools like getcontactsignals shows up as a distinct tool span in your LangSmith dashboard. You can monitor input tokens, output tokens, and execution times for every Middle Eastern contact query.

Q: What happens if a LinkedIn message fails to send?

The sendlinkedinmessage tool returns a structured error payload detailing the failure reason. Your agent can catch this exception, log the failure in your chain state, and attempt a fallback path.

Feed native Arabic business intelligence and LinkedIn workflows directly into your LangChain reasoning loops.

Run Arabic prospecting chains inside LangChain

This MCP Server lets your LangChain agent run `list_companies` to identify Middle Eastern targets and feed those results directly into the next chain step. You get native Arabic comprehension out of the box, meaning your pipeline reads regional market signals without losing cultural nuance in translation. LangSmith traces every step of this sequence so you see exactly how the agent parses the company data. If the model decides to trigger `get_contact_signals` based on what it finds, you can audit the latency and token spend of that specific transition.

Automate regional outreach with multi-step chains

The `create_contact` tool registers new Middle Eastern leads directly from your chain's output variables. Your agent evaluates the buyer profile, matches it against active campaigns, and prepares a localized approach. Once the contact details are set, the chain triggers `send_linkedin_message` to initiate contact. This entire flow runs asynchronously inside your LangGraph state, keeping human-in-the-loop approvals simple before the message actually goes out.

Track Middle Eastern campaigns with LangSmith observability

Your agent calls `list_campaigns` to pull active outreach metrics and adjust its next actions dynamically. LangChain monitors this MCP tool call to ensure the returned Arabic text patterns map correctly to your local agent variables. Because the Vinkius sandbox isolates these network requests, your database credentials remain safe while the agent pulls active campaign lists. You get clean execution logs for every single run without exposing your main environment.

Setup guide

Set up Dalil AI 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 Dalil AI 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({
    "dalil-ai-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 Dalil AI transactions"
    })
    print(result["messages"][-1].content)

Common questions about Dalil AI MCP in LangChain

The server processes Arabic scripts natively before passing structured JSON to your LangChain parser. This prevents common character encoding bugs that break standard python string splitters during chain execution.

Yes, every call to tools like `get_contact_signals` shows up as a distinct tool span in your LangSmith dashboard. You can monitor input tokens, output tokens, and execution times for every Middle Eastern contact query.

Use the MultiServerMCPClient to aggregate this server alongside your other tools. Pass the combined tool list to your ReAct agent so it can decide when to query Arabic business data.

The `send_linkedin_message` tool returns a structured error payload detailing the failure reason. Your agent can catch this exception, log the failure in your chain state, and attempt a fallback path.

Your contact records and LinkedIn messages never persist on Vinkius disks. The V8 sandbox runs each execution in memory and wipes the environment clean the moment the tool returns its payload.
