Multi-Step Reasoning Pipelines

You can set up multi-step chains that pass data between tools. For example, you first run `list_companies` to get a list of IDs, then take one ID and feed it into `get_contact_details`. This process lets your agent decide the exact sequence of tool calls based on what it finds in intermediate steps. This makes building complex logic simple. Your AI client doesn't just call tools; it uses the output—like a specific contact's phone number—to determine the next best action, which might be querying `list_activities` for that account.

Evaluating Opportunities in LangChain

The `list_opportunities` tool lets your agent see every deal in the pipeline. You'll use this data to build decision logic: if an opportunity is stuck at a certain stage, the chain can automatically trigger a check using `get_company_details` to find recent news, giving context for a follow-up.

Full Activity Mapping with LangChain

The system exposes `list_activities`, which provides a history of calls, emails, and tasks. You can build an agent that reviews this feed first. Then, it uses the resulting dates or topics to decide if calling `get_notes` for more context is necessary before sending a summary report.

Setup guide

Set up Tactile CRM 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 Tactile CRM 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({
    "tactile-crm-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 Tactile CRM transactions"
    })
    print(result["messages"][-1].content)

Common questions about Tactile CRM MCP in LangChain

LangChain treats the MCP Server as a series of connected tools. It doesn't just call them; it uses the output from one tool (say, company IDs) to intelligently decide which parameters are needed for the next tool call.

Yes. Because LangChain supports full observability via tracing, you get a clear log of every step—every tool input and output—that your agent used against the MCP Server.

You can aggregate tools. If you want details on five contacts, your chain first calls `list_contacts`, gathers all the IDs, and then loops through them, calling `get_contact_details` for each one sequentially.

It does. You can use client.session() to maintain state between runs, so the agent remembers which companies or contacts it looked at earlier in the workflow.

The server handles structured data for organizations (`list_companies`), people (`list_contacts`), deals (`list_opportunities`), and communication history (`list_activities`). All these data points are available as tool inputs.
