INSTALL THIS SERVER

Requires authenticationK6_CLOUD_TOKEN environment variable for Grafana Cloud k6 features. Local k6 execution requires the k6 binary installed on the host.

PrereqInstall via `go install github.com/grafana/mcp-k6@latest`. Set K6_CLOUD_TOKEN for Grafana Cloud k6 features. Local k6 execution requires the k6 binary on the host (https://k6.io/docs/get-started/installation). Path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS).

OUR ASSESSMENT

Strengths
  • Official Grafana Labs maintenance.
  • 33 GitHub stars and AGPL-3.0 licence.
  • 7 commits on main in the last 30 days.
  • Covers both local k6 execution and Grafana Cloud k6 (hosted load testing).
  • Pairs with the existing Grafana MCP entry: this one focuses on load tests, the existing one focuses on dashboards.
  • AGPL-3.0 permits production use; copyleft restricts offering k6 as a competing managed service.
Weaknesses
  • 33 GitHub stars; adoption is early.
  • AGPL-3.0 has copyleft obligations distinct from MIT or Apache; review for downstream commercial use.
  • Grafana Cloud k6 features require a Grafana Cloud subscription; local k6 execution needs k6 binary installed.
Security Notes

The MCP carries the Grafana Cloud k6 API token (when used) plus filesystem access for local k6 scripts. Scope the API token to a single project. k6 scripts can target arbitrary endpoints; review scripts before letting an agent invoke run_test against production targets.

Best For

Performance engineering teams running k6 for load testing who want agents to trigger test runs and query results inside the editor; CI workflows that benefit from agent-driven load test interpretation; teams using Grafana Cloud k6 for hosted load testing.

SOURCES & VERIFICATION

We don't take any single directory's word for it. Before scoring, we cross-reference 4 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.

// How other directories see it

The same server, 4 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
