Use Fortran MCP to improve AI-assisted Fortran development with cited documentation on language features, compiler behavior, build systems, and the wider ecosystem.

It supports lexical, semantic, and hybrid search, returning relevant passages with source attribution, version information, and links to the original documentation.

## Installation

Requires Python 3.11+ and [uv](https://docs.astral.sh/uv/).

Install the Fortran MCP server:

```bash
uv tool install fortran-mcp
```

Semantic and hybrid search require additional dependencies:

```bash
uv tool install "fortran-mcp[semantic]"
```

Data bundles are installed automatically on first run. You can also install them beforehand to avoid an initial delay:

```bash
fortran-mcp data install core      # for lexical search
fortran-mcp data install semantic  # for semantic and hybrid search
```

Check the installation:

```bash
fortran-mcp doctor
```

Use `FORTRAN_MCP_AUTO_INSTALL=0` to disable automatic installation, or set `FORTRAN_MCP_CATALOG` to point to a local catalog path or HTTPS URL.
