README

One local MCP connection for KillerTools and the Killer app family: KillerPDF, KillerNotes, KillerScan, KillerShell, Killendar, and KillerBench.

KillerMCP is a native .NET 10 host. It detects supported Killer apps, exposes their available commands, and registers one MCP server with compatible agent clients. The separate [KillerTools repository](https://github.com/SteveTheKiller/KillerTools) provides the shared engine for the website utilities.

Install

[Download the signed KillerMCP installer](https://github.com/SteveTheKiller/KillerMCP/releases/latest/download/KillerMCP-Setup.exe), run setup, then open a new agent chat. Setup checks for the .NET 10 runtime and registers KillerMCP with Codex, Claude Code, Claude Desktop, Cursor, GitHub Copilot, Gemini CLI, and Windsurf when those clients are found.

You can also install it with WinGet or Chocolatey. Both install the .NET 10 Desktop Runtime for you when it is missing.

winget install SteveTheKiller.KillerMCP
choco install killermcp

Fully quit and reopen an agent client after setup or upgrade, then start a new chat. In Claude Desktop, KillerMCP appears under Settings > Developer as a running local server and under Connectors as a desktop connector. Cowork can use that local connection without a separate plugin.

Once connected, ask naturally:

killer domain search example.com
killer merge these PDFs
killerscan my network
killer update status

The server supplies tool descriptions and instructions that help the client select the appropriate tool. Client behavior varies, so these phrases are guidance rather than guaranteed commands.

KillerMCP checks GitHub Releases hourly and shows a Black/Fuchsia update window when a newer version is avai
