MCP Gateway for Agents

Connect your agents to any tool. Authenticated, scoped, and logged.

500+ connectors and 20,000+ tools behind one MCP endpoint. Your agents act for your users, with only the access each job needs.

Trusted by teams shipping agents to production

One MCP gateway between your agent and every tool it calls.

The right credentials, a permission check, a clean request and a readable response. Handled on every call, so you build the agent, not the integration layer.
Managed auth
Users connect their own accounts. We store the tokens, refresh them, and attach them to every call. Nothing lands in your code.
20,000+ tools
Across 500+ connectors, from CRM and email to tickets and billing. Your agent calls them as the user it's working for.
Scoped tool access
Decide which tools each agent can see. The gateway enforces it, so it doesn't rely on instructions in your prompt.
Logs on every call
Which agent, which user, which tool, what came back. Searchable, exportable, and streamable to Datadog, Splunk, or any SIEM.

500+ connectors.

20,000
tools.
CRM, email, calendar, tickets, docs and billing. Every tool is written for a model to read, so your agent picks the right one and sends the right arguments.

More control over every tool call. Scope it, trigger it, extend it.

Decide which tools each agent gets, what starts a run, and what to add beyond the catalog.
Virtual MCP Servers

Build a tool set for each agent.
‍From any app, behind one endpoint.

Connect four apps and your agent sees 100+ tools. Give it the five its job needs, picked from any app and served as one endpoint.
Leaner context. Around 80% less tool overhead.
Just the right access. Each agent gets its role's tools, nothing more.
Same job, same result. Fewer choices, fewer wrong calls.
Triggers

Start a run the moment something happens.
‍In any app your user has connected.

A new email, a deal changing stage, a failed payment. Your agent starts on it right away, already acting as that user.
Listens where it already acts. Uses the accounts your users already connected.
Runs as the right user. Their access, from the first call.
No infrastructure to own. No polling, cron jobs or webhook endpoints.
Custom tools & connectors

Add any API your agent needs.
‍Managed like everything else.

Internal services, partner APIs, endpoints the catalog doesn't cover yet. Add them once, with the same auth, scoping and logs as everything else.
Extend a connector. Add an endpoint it doesn't expose yet.
Bring a new system. OAuth 2.0, API keys, bearer or basic auth.
Bring your own MCP server. Its tools join the catalog.

Credentials never touch your code.
Or your agent's context.

Every user's tokens are stored, refreshed and kept to that user at the gateway. Your code never sees one.
Connected accounts
Your agent acts as the user
Each user connects their own accounts, with the permissions they granted. One user's run can't reach another's.
Token vault
Tokens stored and kept fresh
Encrypted per tenant and refreshed before they expire. Your code and prompts never hold one.
Every auth model
Every auth method, one integration
OAuth 2.0, API keys, bearer tokens and more, behind a consent screen on your own domain.

See every tool call your agents make.
And who they made it for.

Every call, fully attributed
Agent, user, tool and result on every call. Nothing to piece together later from application logs.
Stream it to your SIEM
Datadog, Splunk or any SIEM, as calls happen. Attribution travels with every event.
Know where a failure came from
Every failure is marked as a connector error or an API error, so you know whether to fix your setup or wait.
Works with the agent framework you already use

CUSTOMERS

Agents in production, in their words.

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
CTO, 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.
