perfscale MCP servers

Model Context Protocol servers for perfscale:

Quick start

OSS (local)

Requires the perfscale CLI on PATH (or PERFSCALE_BIN).

{
  "mcpServers": {
    "perfscale": {
      "command": "npx",
      "args": ["-y", "@perfscale/mcp"]
    }
  }
}

Tools: run_test, lint, get_schema, parse_summary, list_actions, list_configs, read_config, write_test, write_config, update_config, remove_config.

Controlplane (cloud)

Create an API token in the dashboard (Settings → API Tokens; Scale plan: 1 per user, Enterprise: 5 per user), then:

{
  "mcpServers": {
    "perfscale-cloud": {
      "command": "npx",
      "args": ["-y", "@perfscale/controlplane-mcp"],
      "env": {
        "PERFSCALE_API_URL": "https://perfscale.su",
        "PERFSCALE_API_TOKEN": "psk_..."
      }
    }
  }
}

Tools: whoami, tenant_limits, list_machines, get_machine, list_tests, get_test, list_runs, get_run, get_run_logs, runs_by_machine, run_test, metrics_catalog, query_metrics, get_otel_timeseries, list_dashboards, list_git_repos, sync_git_repo, list_env_vars (values masked), audit_log.

Development

pnpm install
pnpm test        # vitest across all packages
pnpm build       # tsc -b per package

Releasing

Bump the version in the package's package.json, then tag and push:

git tag v0.2.0 && git push origin v0.2.0

CI publishes to npm (release.yml); packages whose version is already on the registry are skipped, so packages version independently. Requires the NPM_TOKEN repo secret.
