What Kranz does

According to its repository: “Local service orchestrator with a stdio MCP server for inspecting and controlling development services, logs, ports, actions and run history across live project runtimes.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Kranz is listed under Developer tools, a category of 475 servers in the directory, where it ranks #233 by stars.

Topics declared by the repository: devtools, go, homebrew, process-manager, terminal, tui.

Installing and connecting Kranz

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Go. Listed systems: macOS, Linux.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Kranz. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on July 21, 2026, the kranz-org/kranz repository has 62 stars and 2 forks, with 0 open issues. It has more stars than 56% of the servers in the directory. It received changes this month.

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
