How to Use the Tray.io MCP in LangChain

Q: Can LangChain list all available connectors in Tray.io?

Yes. The listavailableconnectors tool provides an inventory of every service connector, such as Slack or Salesforce. Your agent uses this to confirm the operational scope before writing a new automation.

Q: Does Tray.io allow LangChain to find all existing automations?

Absolutely. The listworkflows tool lists every single workflow in your account. This lets your agent build an initial map of the entire operational landscape within Tray.io.

Perplexity

Discovering available workflows and integrations.

The `list_workflows` tool lets your agent see every automation running in the account. You can quickly check what automations exist before trying to modify them. The `list_integration_solutions` tool gives a rundown of all pre-built integration templates. This is useful for understanding which connection types are ready to go.

Monitoring data execution flows.

Need to know if a workflow actually ran? Use `list_workflow_executions` to pull recent history for any specific process. You get details on when it started and what the results were. The agent can also check the status of an entire operation using `get_workflow_details`. This lets your AI client track down exactly where a run got stuck.

Identifying connected services.

The `list_available_connectors` tool shows every service that can plug into Tray.io, like Salesforce or Slack. Your agent uses this to validate which systems are actually available for the job. Furthermore, `get_authenticated_user` retrieves details about the current user. This lets your agent know who's running the automation and what their permissions are.

Setup guide

Set up Tray.io 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 Tray.io 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({
    "trayio-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 Tray.io transactions"
    })
    print(result["messages"][-1].content)
