### Description (declared)

# dlubal-mcp

**Model Context Protocol (MCP) server** that enables AI tools and large language models (LLMs) to interact with running [Dlubal](https://www.dlubal.com) structural analysis applications.

Built on top of the [dlubal.api](https://pypi.org/project/dlubal.api/) gRPC client library, `dlubal-mcp` exposes tools that AI assistants can call directly to do modelling, analysis or reading results through the API scripts.

## Supported Applications

| Application | Script Tool |
|---|---|
| **RFEM 6** — Finite Element Analysis | `run_rfem_script` |
| **RSTAB 9** — Frame and Truss Analysis | `run_rstab_script` |
| **RSECTION 1** — Cross-Section Analysis | `run_rsection_script` |

## How It Works

### HTTP access protection

Starting with 1.0.13, HTTP access always requires a separate bearer token and a
numeric loopback bind address. The matching Dlubal Connector provisions this
automatically. Standalone clients must configure `DLUBAL_MCP_ALLOWED_API_KEYS`
and send `Authorization: Bearer <access-token>`; the Dlubal application API key
is a separate credential. Anonymous operation and query-string tokens are not
supported. See [HTTP authentication and upgrade notes](docs/http-authentication.md).

`dlubal-mcp` acts as a bridge between an AI assistant and a running Dlubal application. The application must already be open and its API service active — the MCP server connects to the live session, it does not launch applications itself.

1. Start RFEM 6, RSTAB 9, or RSECTION 1 on your machine
2. Launch the MCP server with proper settings (urls, API ports)
3. An AI tool calls e.g. `run_rfem_script` with Python code
4. The code executes against the live application and returns the output

### LLM Responsibility for API Scripts

The `run_rfem_script`, `run_rstab_script`, and `run_rsection_script` tools execute arbitrary Python code against the live application. **The LLM is responsible for composing correct and valid API scripts** — the MCP server simply runs whatever code i…
