              or a Contribution incorporated within the Work constitutes direct
              or contributory patent infringement, then any patent licenses
              granted to You under this License for that Work shall terminate
              as of the date such litigation is filed.
        
           4. Redistribution. You may reproduce and distribute copies of the
              Work or Derivative Works thereof in any medium, with or without
              modifications, and in Source or Object form, provided that You
              meet the following conditions:
        
              (a) You must give any other recipients of the Work or
                  Derivative Works a copy of this License; and
        
              (b) You must cause any modified files to carry prominent notices
                  stating that You changed the files; and
        
              (c) You must retain, in the Source form of any Derivative Works

                  include a readable copy of the attribution notices contained
                  within such NOTICE file, excluding those notices that do not
                  pertain to any part of the Derivative Works, in at least one
                  of the following places: within a NOTICE text file distributed
                  as part of the Derivative Works; within the Source form or
                  documentation, if provided along with the Derivative Works; or,
                  within a display generated by the Derivative Works, if and
                  wherever such third-party notices normally appear. The contents
                  of the NOTICE file are for informational purposes only and
                  do not modify the License. You may add Your own attribution
                  notices within Derivative Works that You distribute, alongside
                  or as an addendum to the NOTICE text from the Work, provided
                  that such additional attribution notices cannot be construed
                  as modifying the License.
        
              You may add Your own copyright statement to Your modifications and
              may provide additional or different license terms and conditions
              for use, reproduction, or distribution of Your modifications, or
              for any such Derivative Works as a whole, provided Your use,

           5. Submission of Contributions. Unless You explicitly state otherwise,
              any Contribution intentionally submitted for inclusion in the Work
              by You to the Licensor shall be under the terms and conditions of
              this License, without any additional terms or conditions.
              Notwithstanding the above, nothing herein shall supersede or modify
              the terms of any separate license agreement you may have executed
              with Licensor regarding such Contributions.
        
           6. Trademarks. This License does not grant permission to use the trade
              names, trademarks, service marks, or product names of the Licensor,
              except as required for reasonable and customary use in describing the
              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions
              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
              PARTICULAR PURPOSE. You are solely responsible for determining the
              appropriateness of using or redistributing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,
              and charge a fee for, acceptance of support, warranty, indemnity,
              or other liability obligations and/or rights consistent with this
              License. However, in accepting such obligations, You may act only
              on Your own behalf and on Your sole responsibility, not on behalf
              of any other Contributor, and only if You agree to indemnify,
              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.

# 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](https://below280.com), the UK partner for openLCA.

The server exposes 31 tools covering the full LCA workflow: exploring databases, building and editing models, running calculations (scenarios, sensitivity, Monte Carlo, contribution analysis), auditing and validating models, and extracting data quality assessments. All calculation patterns are tested against production ecoinvent databases.

The server works with both ecoinvent-family databases (ecoinvent, EN15804GD, HiQLCD, BAFU) and FLCAC-family databases (LCA Commons, US LCI, USEEIO). It asks which family you are using, or auto-detects from the flow property names.

Available on [PyPI](https://pypi.org/project/b280-olca-mcp/) and the [MCP Registry](https://registry.modelcontextprotocol.io).

## Install

### Quick setup (PyPI)

```
pip install b280-olca-mcp
```

This installs the server and its dependencies (`mcp`, `olca-ipc`) in one step. The server runs from anywhere with `python -m b280_olca_mcp`.

### Development setup (GitHub)

Clone the repository for the latest code, the React dashboard, or if you want to modify the server:

```
git clone https://github.com/Below280/B280-olca-MCP.git
cd B280-olca-MCP
pip install -r requirements.txt
```

The server entry point is `b280_olca_mcp/server.py`.

## What it does

Someone using this MCP can say things like:

- 'Make me a model with 34 kWh UK electricity, 5 kg sodium hydroxide, and 34 kWh steam'
- 'Build an EPD model from this LCI'
- 'Run two scenarios, one with transport at 100 km and one at 500 km'
- 'Which processes contribute most to climate change in my system?'
- 'Vary the electricity and PET resin parameters by 10%'
- 'Validate my product system and check if the linking is correct'
- 'Run 1000 Monte Carlo iterations and show me the uncertainty'
- 'Help me connect to openLCA from R / Go / Rust'
- 'What can you do?' (the help tool)

The AI assistant handles the conversation, builds the tool calls, and presents results visually with charts, tables, and exportable data.

## Connect your MCP client

The server uses stdio transport. Any MCP client that can spawn a local Python process will work.

### Claude Desktop

In Claude Desktop, go to Settings > Developer > Edit Config. Add an `openLCA` entry to the `mcpServers` section.

If you installed via PyPI:

```json
{
  "mcpServers": {
    "openLCA": {
      "command": "python",
      "args": ["-m", "b280_olca_mcp"],
      "env": {
        "OLCA_PORT": "8080"
      }
    }
  }
}
```

If you cloned from GitHub:

```json
{
  "mcpServers": {
    "openLCA": {
      "command": "python",
      "args": ["C:/path/to/B280-olca-MCP/b280_olca_mcp/server.py"],
      "env": {
        "OLCA_PORT": "8080"
      }
    }
  }
}
```

On Windows, if Claude Desktop cannot find Python, use the full path to your Python executable.

Restart Claude Desktop after saving.

### Cursor

Go to Settings > Tools & MCP > Add MCP Server. Choose stdio transport, set the command to `python` and the argument to `-m b280_olca_mcp` (PyPI) or the path to `b280_olca_mcp/server.py` (GitHub clone). Cursor picks up config changes without restarting.

### VS Code

Add the server to `.vscode/mcp.json` in your workspace or user settings:

```json
{
  "servers": {
    "openLCA": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "b280_olca_mcp"],
      "env": {
        "OLCA_PORT": "8080"
      }
    }
  }
}
```

Note: VS Code uses `servers` as the root key, not `mcpServers`. If using GitHub Copilot, switch Copilot Chat to Agent mode.

### ChatGPT

ChatGPT does not directly launch a local stdio server. A public Streamable HTTP endpoint remains the standard deployment route. For developer testing, OpenAI documents Secure MCP Tunnel, which can connect ChatGPT to a private stdio server without exposing it publicly.

### Other MCP clients

Any client that spawns a local Python process over stdin/stdout should work. With PyPI: `python -m b280_olca_mcp`. With GitHub clone: `python path/to/b280_olca_mcp/server.py`.

## Start it

1. Open your database in openLCA
2. Start the IPC server (Tools > Developer Tools > IPC Server > green play button, port 8080)
3. Restart your MCP client (or reconnect)
4. Ask something like 'what can you do?' or 'what's in my openLCA database?'

After creating or modifying anything, press the Refresh button in openLCA's toolbar to see changes in the GUI.

## Data security

The MCP server runs locally and communicates with openLCA on localhost. The AI client (Claude Desktop or equivalent) sends tool results to its provider's servers for processing. This means process names, exchange data, parameter values, and impact results from your database will be in the conversation.

**Do not connect a confidential client database through a personal or free-tier AI account.** Use a business or enterprise account with appropriate data retention controls, and check your provider's data processing terms before connecting any database containing sensitive information.

## Tools

### Explore (11 tools)

| Tool | Purpose |
|---|---|
| `database_info` | Counts of systems, processes, flows, methods, parameters. Auto-detects database family |
| `set_database_family` | Set ecoinvent or FLCAC naming conventions |

### Meta (1 tool)

| Tool | Purpose |
|---|---|
| `help` | Show capabilities grouped by workflow, with optional topic filter |

## Tool annotations

Every tool carries MCP tool annotations (`readOnlyHint`, `destructiveHint`, `idempotentHint`, `openWorldHint`) so clients can decide whether to auto-approve or prompt for confirmation. Explore and Calculate tools are read-only. Build tools signal that they modify the database. `delete_entity` is marked destructive. CSV tools are marked as writing files to disk. `chemical_synonyms` is marked as reaching an external service (PubChem).

## Resources

The server exposes four MCP resources that AI clients can read on demand:

| Resource | URI | Purpose |
|---|---|---|
| Database info | `lca://database/info` | Live database overview |
| Assistant instructions | `lca://knowledge/instructions` | Operational rules, workflows, and conventions |
| IPC protocol reference | `lca://knowledge/ipc-protocol` | Complete JSON-RPC spec for all 60 IPC methods |
| openLCA resources | `lca://knowledge/openlca-resources` | Links to databases, docs, forums, and training |

The IPC protocol reference enables AI clients to help users connect to openLCA from any programming language by generating client code from the protocol specification.

## EPD model building

The server includes a guided workflow for building EN15804 EPD models from LCI data. The AI maps LCI items to lifecycle modules (A1-D), creates the folder structure, bridge processes, module processes, and product systems. Ask 'build an EPD from this LCI' to start.

## Standalone scripts

For repeated analyses, the server recommends standalone Python scripts that run without AI tokens. After a scenario or sensitivity calculation, it offers to generate the CSV file needed to run the equivalent script from the [openLCA-IPC-tools-python](https://github.com/Below280/openLCA-IPC-tools-python) repository.
