### Description (declared)

# MCP TAXII

A Model Context Protocol (MCP) server that acts as a TAXII client for AI agents, enabling them to interact with Threat Intelligence platforms using the TAXII protocol.

## Overview

MCP TAXII provides a bridge between AI agents and TAXII (Trusted Automated eXchange of Intelligence Information) servers, allowing AI systems to:
- Query threat intelligence data
- Retrieve STIX objects from TAXII collections
- Discover available threat intelligence sources
- Add new threat intelligence to collections (when permitted)

The server supports both TAXII 2.0 and TAXII 2.1 protocols.

## Features

- **TAXII 2.0 & 2.1 Support**: Compatible with both major TAXII protocol versions
- **FastMCP Framework**: Built on FastMCP for efficient MCP server implementation
- **Authentication Support**: Handles username/password authentication for TAXII servers
- **Collection Management**: Browse, query, and interact with TAXII collections
- **STIX Object Operations**: Retrieve and add STIX threat intelligence objects
- **Pagination Support**: Handles large datasets with built-in pagination (TAXII 2.1)
- **Environment Variable Configuration**: Easy setup via environment variables

## Quick Start with uvx (No Installation Required)

`uvx` is a tool that allows you to run Python packages without installing them. This is perfect for:
- **Quick testing** without cluttering your system
- **Running in CI/CD** pipelines
- **Isolated execution** without dependency conflicts
- **Always running the latest version**

### Prerequisites for uvx

```bash
# Install uv (which includes uvx)
pip install uv
# or
pipx install uv
```

### Running Directly from PyPI

Once published to PyPI, you can run MCP TAXII instantly:

```bash
# Run the latest version
uvx mcp-taxii

# Run a specific version
uvx mcp-taxii==0.1.0

# With environment configuration
MCPTAXII_HOST="http://localhost:8000/taxii21/" \
MCPTAXII_USERNAME="admin" \
MCPTAXII_PASSWORD="admin_password" \
uvx mcp-taxii
```
