Introducing the Real-Time LCA MCP Server

We’re thrilled to announce the public launch of the Real-Time LCA MCP Server. With this hosted Model Context Protocol server you connect your AI directly to Real-Time LCA. No local installation, no manual API calls, no scripting. Just natural language and your existing Real-Time LCA account.

What you can do

Connect once, and your AI gains access to your Real-Time LCA workspace:

  • Projects: List and manage building projects; view GWP metrics, status, and metadata at a glance

  • Material Mapping: Map BIM materials to EPDs from the global library, preview AI-suggested matches, or trigger full automapping in one step

  • BIM Inspection: Traverse construction hierarchies, identify unmapped types, and drill into material properties

  • LCA Reports: Generate BR18-compliant XML and Excel reports and download them directly

  • EPD & Materials Library: Search by name, category, datasource, or manufacturer; create, patch, and map EPDs and constructions to your inventory.

  • Dashboards & Timelines: Pull GWP summaries, emissions-over-time charts, stage breakdowns, and project event histories

53 tools are available across 7 functional areas.

How to connect

The server is hosted at https://mcp.realtimelca.com/mcp and ready to use. Authentication is handled via OAuth using your existing Real-Time LCA login — no API keys required.

Claude AI

Configure MCP servers in Claude.ai

  1. Add servers at claude.ai/customize/connectors. On Team and Enterprise plans, only admins can add servers.

  2. Plus sign → Add custom connector → Add this URL https://mcp.realtimelca.com/mcp

  3. Authenticate the MCP server

  4. Complete any required authentication steps in Claude.ai.

The next time you mention RTLCA in a chat, Claude will detect the access and ask you for permission to execute tools.

Claude Code

Run this single command in your terminal:


claude mcp add realtimelca --transport http https://mcp.realtimelca.com/mcp

Claude Code will prompt you to authenticate on first use.

Local AI

We are also preparing a guide on how to connect to this MCP via a local LLM. Then you don’t need Claude or other subscriptions. No token limit, no sharing of data. Stay tuned…

Example prompts to try

  • “List all my projects and show me the GWP for each”

  • “Which materials in project X are still unmapped?”

  • “Map missing materials with most adequate EPDs and show me the suggested matches”

  • “Generate a BR18 XML report for project X”

  • “Search the EPD library for mineral wool insulation from Danish manufacturers”

  • “What’s the GWP breakdown by life cycle stage for project X?”

  • “Show me emissions over time for project X”

  • "What are five promising mitigation actions to reduce environmental impacts in the structure of this project?
