How to Use the Gripr MCP in LangChain

Q: Can a LangChain chain call multiple Gripr tools sequentially?

Yes, you can build chains where your LangChain agent calls listprojects first, selects the target ID, and then calls createtask to assign safety audits.

Run multi-step construction safety and project tracking chains in LangChain using Gripr.

Run multi-step construction compliance chains with LangChain

Your LangChain agent can chain `list_forms` to inspect safety reports and then immediately run `create_task` to assign corrective actions. This MCP Server makes it easy to build reactive compliance workflows that trigger based on actual field data. By chaining these tools, you build workflows that react to real-time field data. The output of one tool feeds directly into the next, allowing your agent to check project status via `get_project_details` and then immediately update worker schedules.

Track labor hours and project budgets automatically

This MCP Server lets your LangChain agent track labor hours by pulling active files using `list_registered_hours` in a single execution chain. You don't have to chase down foreman logs at the end of the week. You can build a chain that pulls users with `list_workspace_users` and crosses that data with `list_projects`. This lets you verify hours against active project lists in real time.

Trace every Gripr tool execution in LangSmith

This MCP Server allows you to trace every call to `register_hours` or `create_customer` inside LangSmith. You see the exact latency, token usage, and tool inputs for every safety audit. If `list_tasks` fails to return results during a safety check, you don't have to guess why. You can inspect the exact payload sent by your agent to find the issue.

Setup guide

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

Common questions about Gripr MCP in LangChain

Install the adapter package and initialize the client using `MultiServerMCPClient`. Pass the tools to your LangChain agent constructor to start managing construction tasks.

Yes, you can build chains where your LangChain agent calls `list_projects` first, selects the target ID, and then calls `create_task` to assign safety audits.

Your LangChain agent uses ReAct reasoning to catch errors from this MCP Server and can retry the call with corrected arguments.
