7 TOOLS AVAILABLE
OUR ASSESSMENT
- Harness official maintenance.
- 74 commits on main in the last 30 days. Very high cadence.
- MIT license.
- Covers CI/CD plus feature flags plus chaos in one MCP.
- Go binary; no runtime dependencies.
- 52 GitHub stars indicates limited adoption to date.
- Harness account required.
- toggle_feature_flag is destructive; agent prompt path needs review.
- execute_pipeline can deploy to production environments; gate carefully.
HARNESS_API_KEY is account-scoped. Use a service-account key with the minimum role required for the agent flow. toggle_feature_flag in production environments can affect live traffic; restrict to non-production accounts for agent loops or require explicit operator confirmation in the agent prompt path.
Harness customers adopting agent-driven CI/CD; SREs managing pipelines and feature flags from inside agents; platform teams that want one MCP for the Harness suite.

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 5 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
