Scalekit for agent BUILDERS

Build the agent logic.
‍We handle the rest.

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. Auth plumbing shouldn't stop them.

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.

The tool catalog

100+ connectors out of the box. Extend to anything else.

The apps your agents need most, ready on day one.
Internal APIs, niche tools, custom actions — same connection model, no rebuilding.

ready now

Built-in connectors + pre-built tools

100+ connectors, each shipped with a library of tools your agent can call directly. Every tool is tested, schema-optimised for LLMs, and ready to use — via API or MCP. Auth, pagination, retries, and rate limits handled for every call.

100+ connectors available

~30 min

Custom tools on existing connectors

Need an action that isn't in the default tool library? Define the schema once and point it at any endpoint on an existing connector. Scalekit injects the user's credentials automatically. Your agent calls it exactly like a built-in tool.

Any endpoint, any connector

define once

Bring your own connector

Have an internal API or a custom MCP server? Add it as a connector in a few steps. From that point it behaves identically to a built-in — auth handled, tools callable, full audit trail. No second-class connectors.

Expose your tool stack over MCP

Define a config once. Scalekit generates a per-user authenticated URL. Point any MCP client at it — tools are discovered and called automatically.

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.

Customer-facing agents

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

Internal org-deployed agents

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."

READ THE FULL STORY

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.

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.

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.

Token lifecycle managed

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

US & EU data residency

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

Audit-ready from day one.

Also on Scalekit

The same stack that ships your product
‍runs your entire org.

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.
