Authentication & Authorization for agents

Let your agents act as the user.
Not a shared service account.

Your agent calls tools. Our auth runtime handles the OAuth flows, token refresh, and credential storage in between.

One MCP proxy between
your agent and any tool it calls.

One SDK call handles the token, the scoped tool call, and the structured response. Tokens never enter your agent or the model.
01
Built-in token vault
Delegated authentication
Tokens stored in an AES-256 encrypted vault. OAuth consent flows carry your brand. Credentials don't enter your agent context or models.
02
Authz for agents
Scoped permissions
Permissions scoped per tool call, not per agent. Agents can't act beyond what the current tool call is authorized for.
03
8000+ tools
Reliable tool calls
500+ pre-built connectors across MCP servers and APIs. 8000+ callable actions. Bring your own custom connector for anything not in the catalog.
04
Agent logs
Tool call observability
Full attribution on every log: who authorized the call, which agent ran it, and the response.Exportable to your SIEM, with clear separation of failures by source.
CUSTOMERS

Teams shipping agents to production.

Customer stories
“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.”
Venu Madhav Kattagoni,
Head of Engineering, Von
“Scalekit gave us the identity layer to ship with confidence. Every agent now acts as its own user, and we can see and control exactly what each one can do.”
Krish Bajaj
Senior Analyst, Tech and AI • Z47
"Enterprise customers required different integrations. We needed to keep shipping. Scalekit was the fastest way to do it without splitting the team."
Erwan Martin
Director, Engineering, Napkin.ai
"We needed an auth solution that just works so we could focus on our core AI features. Scalekit eliminated months of auth complexity."
Harsh Vakharia
Product and solutions, SiftHub
Scalekit's flexibility and speed made implementation a breeze. We got secure, scalable, passwordless auth and have the option to open up other methods like SSO as we see fit, without having to refactor the existing stack
Suman Varanasi
CTO / Fello
“I wanted to get the OAuth layer done without burning a full sprint rebuilding infrastructure we'd already built. Scalekit let us add auth to the existing server, configure the right permissions per tool from a dashboard, and move on. We didn't have to migrate to a new framework or touch the core logic.”

Deploy agents. Secure MCP SERVERS.

Roll agents out across your team.
Secure the MCP servers you ship.

Agent gateway

Deploy agents your team uses internally

The control plane for internal agent deployments. Approve your connector catalog, route each call through the employee's identity, and log every action with attribution.
Auth for MCP

Drop-in OAuth 2.1 for your MCP server

Add login, SSO, and scopes to your remote MCP server. Secure access for human users, agents, and server-to-server calls, all in one layer.
AUTH FOR SAAS

Auth for humans and systems your agents live in.

Login flows, user management, sessions for your app. Manage your tenants, users, RBAC, SSO, and SCIM in one full-stack auth layer.
Security & Reliability

Built for production.

Enterprise-grade security. No exceptions. Every layer covered — storage, transit, residency, audit.
01
Encrypted vault. Your code never sees a credential.

AES-256, per-tenant isolated. Tokens auto-refresh before expiry. Your agent gets an opaque reference - nothing sensitive enters your app, logs, or memory.

02
Multi-region. 99.99% uptime.

US and EU regions with automatic failover. Data residency enforced.

03
Private cloud or On-premise

Deploy in your VPC for full data boundary control. Or let us run it. HIPAA-ready on request.

04
Full delegation chain. Every action logged.

Who authorized, which agent, which tool, what scope, what came back. Queryable, exportable to Datadog, Splunk, or any SIEM. 90-day retention by default.

Get started

From install to first tool call
in minutes.

Install from your terminal, drop in the SDK, ship the same day. Framework-agnostic, with native integrations for the stacks you already use.
FREQUENTLY ASKED QUESTIONS

Common questions that we typically hear

How does Scalekit help my agent connect to apps and APIs?

Scalekit gives your agents authenticated and scoped access to third-party apps — Gmail, Slack, Salesforce, GitHub, Notion, and 100+ more. Scalekit handles the delegated OAuth flow, token storage, and the tool call on behalf of your user. No service accounts, or hardcoded credentials.

How does "acting on behalf of a user" actually work?

When a user authorizes a connector, Scalekit creates a connected account — a per-user token store tied to that user's identity. Every tool call your agent makes uses that specific user's credentials. Actions appear as that user in the target app, and access is limited to exactly what they've authorized.

Which apps and tools are available out of the box?

100+ pre-built connectors covering productivity (Gmail, Google Calendar, Outlook), project management (Jira, Linear, Asana, Notion), CRM (Salesforce, HubSpot), data (Snowflake, BigQuery), code (GitHub, GitLab), and many more. Each connector comes with a ready-to-use tool library.

Can I bring my own app credentials?

Yes, we recommend bringing your own credentials for production agents — set it up once and Scalekit handles per-user token storage, refresh, and state tracking automatically. We also offer managed OAuth for a few applications so you can test the workflow easily.

Which AI frameworks does Scalekit support?

Scalekit is framework-agnostic — tool schemas work with any LLM API. Native integrations are available for LangChain, Google ADK, Anthropic, OpenAI, Vercel AI, and Mastra. Node.js and Python SDKs are available too.

Can I build my own connectors?

Yes. You can build them. Add a custom tool to an existing connector, or bring your own connector entirely by defining its auth pattern and tool schemas. Scalekit manages credential storage and injection — your custom connector works exactly like a built-in one.

Can I request for a new connector?

Yes, you can. Go ahead and fill out the form below so we can build it for you. Typically, it should be live and ready to use within 1 week. https://portal.usepylon.com/scalekitsupport/forms/request-a-connector-tool

What if I need to connect my agent to an internal API?

You can bring your own connector by defining its auth pattern and tool schemas. Scalekit manages credential storage and injection — your custom connector works exactly like a built-in one.
