### Description (declared)

# JACTUS MCP Server

**Standalone MCP server for [JACTUS](https://github.com/pedronahum/JACTUS)** — Enables AI assistants like Claude Code to directly access JACTUS financial contract simulation capabilities.

## What is this?

[Model Context Protocol (MCP)](https://modelcontextprotocol.io) is a protocol that allows AI assistants to interact with external tools. This package gives Claude (and other MCP-compatible assistants) the ability to discover, validate, and simulate all 18 ACTUS financial contract types powered by [JACTUS](https://github.com/pedronahum/JACTUS).

## Installation

```bash
pip install jactus-mcp
```

This installs the MCP server and pulls `jactus` as a dependency automatically.

### Download Docs & Examples

After installing, optionally download JACTUS documentation and examples from GitHub:

```bash
jactus-mcp setup
```

This downloads the matching version's `docs/` and `examples/` into `~/.jactus-mcp/data/`. You can also specify a tag:

```bash
jactus-mcp setup --tag v0.2.0   # specific version
jactus-mcp setup --force         # re-download
jactus-mcp status                # check what's downloaded
jactus-mcp clean                 # remove downloaded data
```

### From GitHub

```bash
pip install git+https://github.com/pedronahum/JACTUS-MCP.git
```

### For Development

```bash
git clone https://github.com/pedronahum/JACTUS-MCP.git
cd JACTUS-MCP
pip install -e ".[dev]"
```
