Scalekit for agent BUILDERS

Build the agent logic.
We handle the connection layer.

Every tool your agent needs, connected and authenticated. You write the logic, not the plumbing.
Get your first tool call running in under 5 minutes. Drop it into your coding agent with a single prompt.

The build tax

Your agents need to act on real systems.
Most teams underestimate what that takes.

Every external API call means OAuth flows, token storage, re-auth, and logging. None of that is your product.

How it works

You own the intelligence.
We own the connection
.

When your agent decides to call a tool, three things need to happen before any data moves.
Here's exactly who handles what.
Drop it into your stack

Already on LangChain? Mastra? It drops in.

Same connection model regardless of which agent framework you're on. Switch frameworks without touching your connector config.

Virtual MCP servers

Each agent gets its own server. It can only call what you put in it.

Compose a virtual MCP server for each agent role — pull exactly the tools it needs from any MCP, and leave the rest behind. At runtime, every call is scoped to the user the agent is acting for.
01
Scoped to the role

Pull the tools each agent needs from any MCP. What you leave out never reaches it — no prompt can call it.

02
Scoped to the user

Every run is bound to the user's own connected accounts. No credentials shared across users.

03
Leaner, cheaper runs

Fewer tools mean a smaller context. Scope an agent to what it needs and cut token overhead up to 80%.

Tools Observability

Your agent is running.
Is it actually working?

Every tool call logged. Errors classified before you have to guess. Know whether your agent never reached the connector — or the connector itself failed.
What teams build with Scalekit

Two kinds of agents. One connection layer.

Shipping to customers or deploying inside your org — same infrastructure, same connection model.
01

Customer-facing agents

Your product. Your customers' tools. Each customer's own connected accounts — isolated, scoped, audited.
02

Internal agents for your team

Your org's tools. Each employee's own identity and access — scoped to what they can see.
LIVE IN PRODUCTIOn

40+ connectors. Zero credential rebuilds.
One auth layer for all of it.

Von builds Al agents that act inside revenue teams' tools on behalf of every customer. Here's how they ship at scale without rebuilding the credential layer per connector.

"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."

Production-grade by default

The infrastructure your agents can depend on.

Every token, every call, every tenant — handled with the same guarantees. Ship to production without rebuilding the trust layer yourself.
01
Isolated token vault

Your tokens never leave our AES-256 encrypted vault. No credential bleeds across tenants. No raw tokens in your codebase or logs.

02
Your audit log, automatically

Every tool call appears in your audit log — who, which tool, what happened. Exportable to Datadog, Splunk, or any SIEM. No instrumentation needed.

03
Token lifecycle managed

Auto-refresh before expiry. Re-auth flows triggered when needed. Scope changes handled silently. Nothing breaks at 3am.

04
US & EU data residency

Choose where your data lives. Private cloud and self-hosted deployment available for regulated industries.

05
Audit-ready from day one.
SOC 2 Type II
ISO 27001

Also on Scalekit

The same stack that powers your product
also runs your org's agents.

The same infrastructure that powers developer-built agent products also handles org-wide agent rollouts — with group-level access, an approved tool catalog, and full visibility into every tool call across your team.

Build what makes your
agent intelligent.
We'll handle what makes it work.

Get connected in minutes. Ship the part that matters.
