openLCA MCP Server

An MCP (Model Context Protocol) server that connects AI assistants to a running openLCA instance. Developed and tested with Claude Desktop; compatible with any MCP client that supports stdio transport. Built by Below280, the UK partner for openLCA. Its 31 documented tools cover system, process, database, flows.

People who work with system, process and database and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install openLCA MCP Server

before you install - you'll need

OLCA_PORT

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add below280-b280-olca-mcp -- uvx b280-olca-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "below280-b280-olca-mcp": {
      "command": "uvx",
      "args": [
        "b280-olca-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-09-01 - young repo, little track record yet

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package b280-olca-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.Below280 is GitHub-verified and matches the repo owner

03 · What openLCA MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can set ecoinvent or FLCAC naming conventions, find processes by name, location, or category, find flows by name and/or category folder, and list parameters for a product system.

06 · openLCA MCP Server FAQ

Is openLCA MCP Server still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-15 and it shipped 4 releases in the last 90 days. We re-verify nightly.

What can openLCA MCP Server do?

How do I install openLCA MCP Server?

Run `uvx b280-olca-mcp`. The README documents one environment variable (OLCA_PORT) to set first. You can also paste the ready-made client config above.

Does openLCA MCP Server run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
