An MCP server that allows AI assistants and LLMs to interact with the Horizon3.ai API using the h3-cli tool.
The H3 CLI MCP Server is designed to integrate the capabilities of the h3-cli tool with AI coding assistants such as Claude, Cursor, and VS Code. This server acts as a bridge, enabling users to schedule and run pentests, query results, and automate security workflows through natural language and LLM tools. It requires a pre-installed and authenticated h3-cli on the user's system, as it does not manage API keys or CLI installations. The server is a thin wrapper that facilitates the use of the h3-cli's full API capabilities via MCP-compatible clients.
Features
- Full h3-cli API access: Everything you can do with the CLI, you can do via LLM tools.
- GraphQL documentation: Fetch up-to-date docs for all available queries and mutations.
- Parameter validation: Clear error messages and examples for all tool inputs.
- Prompt templates: Built-in guidance for pagination, pivots, and common workflows.
- Works with any MCP-compatible client: Claude, Cursor, Windsurf, VS Code, and more.
