Security and trust

Built for the way real teams ship

Every call runs as you — scoped to your license, your credits, and your permissions. Nothing runs, sends, or deletes without the guardrails your security team already expects.

Every tool declares its risk before it runs

— reads run on their own; anything that changes or sends waits for you.
  • Read — looks things up · runs on its own
  • Write — creates or sends · asks you first
  • Destructive — deletes for good · needs explicit OK
How risk tiers work

Scoped to your license

Every request runs as the signed-in user. Your client only lists the tools your license and Connect access allow.

Checklist icon.

Risk-tiered tools

Every tool is labeled read, write, or destructive, with SDK hints so clients can gate side effects before a call runs.

Hand icon.

Human in the loop

Turn on confirmation for write and destructive tools. Destructive actions can't be undone — so your agent asks first.

Key icon.

OAuth 2.1 + PKCE

No shared keys. Tokens refresh automatically and can be revoked any time.

Lead generation that works

I love how accurate their data is, the ease of use for their platform and how quick I am able to research my prospects. Support is paramount in this area and they have it all. Ease of implementation helps a lot. The software is frequently used by my staff. Their integration helps with workflow into our other SaaS stacks.

Great UI/UX, quality data

I appreciate that it is real-time AI data. Other vendors store data and only review it once every 60 days or quarter, making much of the data stale. The UI/UX is clean. The system is easy to use. I have used other competitors and find the accuracy of this data to be far superior.

Great for sourcing relevant contacts

I specifically like the ability to select parameters that fit the profile of your ideal client, and even more so the ability to identify consumers that may be looking for services that fit your scope of work.
