Before you install Harness SDK

What it can access
- An AI agent decides its own next steps and calls whatever tools you give it, so its risk depends on the access you grant.
- Based on its description and topics, it likely needs to act on cloud infrastructure.
Before you install
- Use a role with only the permissions it needs, never an admin key.
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by strands-agents on GitHub, 9,018 stars and 1,458 forks. Popularity is not proof of safety.
- Last code change: Oct 30, 2026.
- Open-source license: Apache-2.0.
