Overview

A k6 extension for performance testing Model Context Protocol (MCP) servers.

Installation

Run Command
No command provided

Security Notes

The `StdioClient` in the `mcp.go` source explicitly allows the k6 test script to specify an arbitrary local executable `path` and `args` (via `exec.Command`). This grants the k6 script direct command execution capabilities on the host system where k6 is running. While intended for interacting with local MCP servers, this poses a severe security risk if the k6 script itself is untrusted or compromised.
