A production agent often needs the same access as the person who asked for the work. Scalekit supplies that access. It is the gateway those agents call, over MCP, when they have to act inside a customer's own software. The Free plan costs $0 and covers 10,000 tool calls plus 10,000 trigger events each month. Growth costs $99 a month for 100,000 tool calls, with extra calls at $0.50 per thousand. Enterprise is quoted. On that plan the Scalekit dashboard can use SSO and SCIM, and a HIPAA BAA is available. Hosted Scalekit runs in Los Angeles or in Frankfurt. Adding EU residency to Growth costs $99 a month. Larger deployments can sit in the customer's VPC, or on infrastructure the customer runs, with air-gapped installs supported. The trust center lists SOC 2 Type II and ISO 27001. Bartłomiej Krupa, a developer at Brand24, said: "We wanted our users to be able to ask their AI tools the same questions they'd ask Brand24 directly. Scalekit let us ship that without turning our engineering team into OAuth specialists." Under the hood, a request for Salesforce, Gmail, Slack, Notion, HubSpot, Jira, GitHub, or another of the 600+ connectors is matched to that person's stored login, allowed or refused, and sent. The catalog covers 35,000+ tools. Logins are encrypted with AES-256 and kept per tenant. The agent receives a result, not the secret. The same path works for code written with Anthropic, OpenAI, LangChain, Google ADK, Vercel AI, or Mastra.

Most companies write permission checks straight into each application, which makes access hard to change, hard to review and hard to prove to an auditor. Cerbos moves those rules into one authorization management platform that covers applications, API gateways, service meshes, data platforms and AI agents. Teams describe who can do what in short policy files that people outside engineering can read. Role, attribute and relationship rules (RBAC, ABAC, ReBAC and PBAC) live side by side. When a request comes in, Cerbos pulls the current roles and attributes from Okta, Microsoft Entra ID, your databases or internal APIs, then checks the request against the policy. A change to the rules ships after its tests pass, with no application release. What each team gets For engineering, one API call takes the place of permission logic spread across services, with SDKs in eight languages including Go, Java, Python and JavaScript. For identity teams, a single place to manage access for employees, customers, services and AI agents, next to the identity provider they already run. For product teams, custom roles and per-tenant permissions for enterprise customers without building them one customer at a time. For security teams, every AI agent tool call goes through the same policy check as a person, so agent rollouts can be approved with controls in place. Each check is recorded along with the policy that applied, which gives SOC 2, ISO 27001 and HIPAA audits a clear trail. Deploy it as a hosted service, in your own cloud or fully air-gapped. Customers running Cerbos in production include Utility Warehouse, 9fin and Salesroom.

Google Cloud Agent Identity provides each AI agent with a unique, cryptographically verified identity along with managed X.509 credentials that enable it to authenticate itself to various Google Cloud resources. The APIs for identity and credential management facilitate agent authentication, access to a range of tools and services, and the management of credentials for user-delegated OAuth flows.
