How to Use the TextP2P MCP in LangChain

Q: What TextP2P tools are best suited for LangChain agents?

All of them. The agent can reason between using sendtextp2psms(), sendtextp2pmms(), and even calling the utility function gettextp2pbalance to check resource limits first.

Q: If I need to check my TextP2P balance in LangChain?

You simply incorporate a call to gettextp2pbalance into your chain. The agent treats it just like any other tool, reporting the result for subsequent reasoning steps.

Perplexity

Build multi-tool decision chains.

The power of the MCP Server is that every tool call becomes a link. You can create an agent where it first calls `list_textp2p_lists` to identify target groups, then uses those IDs in a loop calling `send_textp2p_sms()` for bulk messaging. The output from the list function immediately feeds into the message sending tool—that's how complex reasoning pipelines work with LangChain.

Automate contact management and flow.

You can build a pipeline that first verifies necessary contacts using `add_textp2p_contact`. If successful, the agent decides whether to send an MMS or RVM based on context. It uses `send_textp2p_mms()` if rich media is available, otherwise it defaults to a simple text message. This decision-making process—deciding WHICH tool and WHEN—is what LangChain excels at.

Observe every TextP2P step.

LangSmith tracing gives you full visibility. You can see the latency, token usage, and exact inputs/outputs for every single call to this MCP Server. If a campaign fails or gets rate-limited, you trace exactly which tool call (`get_textp2p_balance` or `send_textp2p_sms()`) caused it. This deep observability is critical when running mission-critical outreach.

Setup guide

Set up TextP2P 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 TextP2P 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({
    "textp2p-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 TextP2P transactions"
    })
    print(result["messages"][-1].content)

Common questions about TextP2P MCP in LangChain

The agent uses the output of one tool as input for the next. For example, it gets a list ID from `list_textp2p_lists` and passes that directly to `send_textp2p_mms()` without manual intervention.

All of them. The agent can reason between using `send_textp2p_sms()`, `send_textp2p_mms()`, and even calling the utility function `get_textp2p_balance` to check resource limits first.

The server handles phone numbers, campaign lists, and account billing details. The LangChain framework allows you to observe these specific inputs and outputs during the execution chain.

Yes. You build a ReAct agent that decides the best tool, whether it's `send_textp2p_rvm` or simple texting, based on the current context and objective.

You simply incorporate a call to `get_textp2p_balance` into your chain. The agent treats it just like any other tool, reporting the result for subsequent reasoning steps.
