How to Use the TrackingTime MCP in LangChain

Q: How do I track time entries using LangChain?

First, your agent calls listtimeentries to see what's logged. Then, it can use the data from that list to either manually add a new entry with addtimeentry, or pass the existing log details to another service.

Q: Can LangChain help me get project lists?

Yep. The agent executes listprojects and returns a clean list of all your projects immediately. This output can then be used as input for creating new tasks or updating existing ones.

Q: What if I need to know who's on my team with LangChain?

You simply invoke the listworkspaceusers tool. The chain outputs a structured list of every user, which you can then feed into other logic for reporting or assignment purposes.

Perplexity

Execute complex workflows via MCP Server

The `add_time_entry` tool lets your agent log time manually, and the `create_project` tool sets up the context. Your AI client builds a chain where one step processes project data, and the next uses that output to correctly format an entry. The agent decides when it needs to run these steps: first it lists projects with `list_projects`, then it calls `add_time_entry` using the resulting IDs. This makes sure every action is grounded in previous results.

Manage team capacity and resources

You can get a full view of your workforce by calling `list_workspace_users`. Then, use `list_customers` to see who those users are working with. The chain combines this data: it identifies the people available and matches them against the list of clients. If you need to update roles or responsibilities, the agent uses `update_task` after gathering user and client context. This ensures your task assignments reflect current team structure.

Track time flow with LangChain

The `start_timer` tool immediately begins logging work duration. Later, the agent can use `list_time_entries` to pull those raw logs into the next step of the chain. It’s a direct handoff: start tracking now, then analyze it later. This process is perfect for complex reports. The user's AI client uses the timing data from `list_time_entries` and passes it directly to generate a summary via another tool call. You get continuous visibility into resource usage.

Setup guide

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

Common questions about TrackingTime MCP in LangChain

First, your agent calls `list_time_entries` to see what's logged. Then, it can use the data from that list to either manually add a new entry with `add_time_entry`, or pass the existing log details to another service.

Yep. The agent executes `list_projects` and returns a clean list of all your projects immediately. This output can then be used as input for creating new tasks or updating existing ones.

Absolutely. Because the MCP Server exposes its tools directly to the chain, LangChain treats `list_tasks` like any other API call. This lets you build multi-step reasoning around your time data.

You simply invoke the `list_workspace_users` tool. The chain outputs a structured list of every user, which you can then feed into other logic for reporting or assignment purposes.

This server primarily handles operational data like project names (`list_projects`), task details (`list_tasks`), and user profiles (`get_user_profile`).
