# Introduction

> Connect AI clients to Real-Time LCA via the MCP server

## What is the MCP server?

The Real-Time LCA MCP server exposes the platform's REST and EPD APIs to AI clients through the [Model Context Protocol](https://modelcontextprotocol.io). Once connected, your AI client can manage building projects, map materials to EPDs, run automapping, generate LCA reports, inspect BIM data, query dashboards, and browse the full EPD library through natural language — without manual file uploads or copy-pasting OpenAPI specs.

All clients connect via OAuth — no API key, no token to paste. The
**RTLCA endpoint** signs you in with your Real-Time LCA account; the
**Autodesk endpoint** signs you in with your Autodesk account via APS
(Autodesk Platform Services).

## Two endpoints

Pick the one that matches your data source. Setup steps are nearly identical; the URL and prerequisites differ.

<CardGroup cols={2}>
  <Card title="Connect to RTLCA" icon="plug" href="/ai-tools/rtlca-mcp">
    The standard endpoint. Connects any AI client to your RTLCA projects,
    materials, EPDs, reports, and dashboards. **Needs only an RTLCA
    account.**
  </Card>

  <Card title="Connect to RTLCA × Autodesk" icon="compass-drafting" href="/ai-tools/autodesk-mcp">
    Adds tools that read from your **Autodesk Forma hub** and **Revit**
    projects. **Needs an RTLCA account + an Autodesk account with Forma
    hub access.**
  </Card>
</CardGroup>

## Available tools

The tool surface depends on which endpoint you connect to. Pick the
endpoint that matches your data source — same client setup, different
tool catalog.
