k6 MCP, Grafana's experimental k6 load testing server

• Checks a k6 script for errors without a real test

  Runs your k6 script once with one virtual user and returns syntax errors, runtime problems and suggested fixes.

  Try: “Validate this k6 script and fix whatever fails.”

  Runs code · validate_script

• Runs a k6 load test on your machine

  Runs a k6 script locally with the virtual users, duration or iterations you choose, then returns the output and raw metrics. The test sends real traffic to whatever the script targets.

  Try: “Run this script with 20 users for 30 seconds against staging.”

• Browses the k6 documentation tree

  Lists k6 documentation sections as a tree, for a chosen k6 version, without the full page text.

  Try: “What sections does the k6 docs have about scenarios?”

  Network · list_sections

• Reads one k6 documentation page

  Returns the full markdown of a k6 documentation section by its slug.

  Try: “Show me the k6 docs page on scenarios.”

• Finds k6 Cloud resources in the Grafana Terraform provider

  Searches the installed Grafana Terraform provider schema for resources whose name matches your search term.

  Try: “Which k6 Cloud resources can I manage with Terraform?”

  Files · search_terraform

• Shows server, k6 and k6 Cloud login status

  Reports details about the mcp-k6 server, the local k6 binary and whether k6 Cloud is logged in.

  Try: “Is k6 installed and am I logged in to k6 Cloud?”

Watch out for

• Load tests send real traffic

  A script with many virtual users can overload a live service. Test against staging and start with a small number of users. github.com

• It runs script code on your machine

  Both the check and run tools execute the k6 script they are given. Read scripts the assistant writes before you approve a run. github.com

• HTTP mode has no sign-in

  The optional HTTP mode has no built-in authentication. Use it only on a trusted network or behind a proxy. github.com

• Experimental

  Grafana warns of sharp edges and asks you to keep a local clone up to date. github.com
