SEE HOW AUTH WORKS

Each user signs in to Datacircle once; Scalekit stores and refreshes their tokens. Tokens stay vaulted, every call is scope checked, and every action is logged.

1

Authorize

Your user connects

Datacircle MCP

once. We tie it to their identity and the meetings they approved — no shared bot account, no org-wide access

Who:

user ‘A’

when:

Once per user

access:

Limited to user

2

Store

Their

Datacircle MCP

token lives in a vault scoped to them. User A's meetings are never reachable by an agent acting for user B, even on the same connection

vault:

encrypted

scope:

per-user

tokens:

auto-refreshed

3

Resolve

When your agent calls a

Datacircle MCP

tool, we fetch the right token server-side. It never touches your agent, never appears in the LLM context, never shows up in your logs

speed:

~40ms

check:

before every call

seen by:

nobody

4

Audit

Every

Datacircle MCP

tool call is logged — who triggered it, which meeting was fetched, what came back. 90 days of history, tied to the user who authorized it

history:

90 days

export:

SIEM-ready

logged:

every call

GTM and RevOps Teams

Outbound prospecting agent

Searches Apollo for prospects matching your ICP, scores and ranks them, drafts personalized outreach in Gmail, and logs every send to Google Sheets. Mail goes out as the rep, not from a shared inbox.

GTM and RevOps Teams

CRM AI agent

Reads the Granola transcript after every call, extracts next steps and updates the HubSpot record, drafts the follow-up in Gmail, and confirms in Slack, all on the rep's own delegated OAuth.

GTM and RevOps Teams

Sales call prep agent

Reads tomorrow's calls from Google Calendar, mines past Granola notes and Attio history for context, and delivers each rep a prep brief in Slack, scoped to the calls that rep actually owns.

GTM and RevOps Teams

Deal intelligence agent

Pulls recent Gong calls, scores deal risk with an LLM, cross-references the record in Attio, and DMs each owner their at-risk deals in Slack. Every read is scoped to that rep's own access.

Why Scalekit

Secure your agent's access. Connectors ship in minutes

01.

Shared tokens break per-user analytics

A shared Datacircle token looks fine in a demo. In production every profile lookup looks like one service account, and you cannot tell which user triggered it. Scalekit resolves the credential of the actual user who triggered the agent, never a shared bot.

// shared key
audit → bot_service_account

// scalekit
audit → user_abc ✓

02.

Authentication is not authorization

03.

Multi-tenancy is architectural

04.

Datacircle today. Ten connectors tomorrow.

“Our agents act across Salesforce, Gong, Google Drive, and more, on behalf of every customer. Scalekit behind the scenes meant we can keep adding tools without ever rebuilding how credentials or tool calling work.”

FAQs

Frequently Asked Questions

Does the agent access Datacircle as the user or as a shared key?

As the user. Each user signs in to Datacircle once, and Scalekit stores and refreshes their tokens. Audit logs attribute every action to that user, not a shared service account.

Where is the Datacircle OAuth token stored?

In Scalekit's managed AES-256 token vault, namespaced per tenant. Refresh is automatic. Revocation is a single dashboard action. Credentials never appear in prompts, logs, or LLM context.

Can I limit what the agent does in Datacircle?

Yes. Filter by tool name in listScopedTools to expose only what you want, for example the free file, balance, and invite tools without datacirclemcp_get_linkedin_profile, which spends from the balance, or datacirclemcp_add_funds, which starts a Stripe Checkout. Scalekit also enforces scope checks before every API call.

What happens when a user revokes Datacircle access?

The connection is invalidated on the next tool call. Subsequent requests for that user fail closed with a clear error. Other users in the tenant remain unaffected. The event is logged for audit.

What can the agent do in Datacircle?

6 tools. 4 are free reads: the balance in USD, the invite link and its sign-up count, the list of downloadable lead files, and a signed download link valid for one hour. datacirclemcp_get_linkedin_profile fetches a live LinkedIn profile at the provider's own price, taken from the balance. datacirclemcp_add_funds starts a Stripe Checkout, and nothing is charged until the user pays.
