Perplexity

Determine safe evacuation paths.

When you run `calculate_max_walking_distance`, your agent gets back the compliance status and specific violation details. This output can then feed directly into a subsequent step, like flagging which areas need immediate code review. You're building reasoning pipelines where one tool's result becomes another's input. You don't just check distance; you use that data to drive the next decision in your complex safety assessment.

Validate structural egress requirements.

Need to know if stairwells are wide enough? Run `determine_min_stair_width` for a minimum required width, population ratio details, and even a safe design recommendation with a built-in safety buffer. This gives your chain reliable metrics. The agent can take the calculated load from an earlier step and pass it here. It makes sure that every structural component meets code requirements before you even get to fire suppression.

Specify required fire extinguisher placement.

The final piece of the puzzle is knowing where to put equipment. Use `specify_extinguisher_requirement` to figure out the needed quantity and type distribution (A, B, C) based on your area's risk class. This ensures every corner is covered. Your multi-step agent can combine distance compliance with population density requirements, ensuring both human flow and fire suppression are accounted for in one continuous workflow.

Setup guide

Set up Fire Safety Calculator 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 Fire Safety Calculator 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({
    "fire-safety-calculator-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 Fire Safety Calculator transactions"
    })
    print(result["messages"][-1].content)

Common questions about Fire Safety Calculator MCP in LangChain

The MCP lets you build multi-step reasoning chains. Instead of running checks separately, your agent can pass the distance violation results to a stair width check. This makes sure every structural requirement is validated sequentially.

The toolset processes inputs like building plans, occupancy load, and local code parameters. It outputs specific compliance status reports, violation details, and structural recommendations that your agent can process.

Absolutely. You can combine this MCP with other services, like a CRM or billing MCP. For instance, an agent could check fire compliance and then automatically generate a required maintenance ticket.

The tool requires defining parameters such as the building's intended use, total occupant load, and specific local codes. The quality of these initial inputs dictates the accuracy of the final compliance report.

This MCP handles structural design data, including building code parameters, occupancy load profiles, and required fire safety metrics. This is all visible through your AI Analytics panel.
