What Alter does
Alter is a secure access control and authorization platform for AI agent workflows, centered on a product called Alter Vault. It gives developers a centralized way to manage OAuth tokens, API keys, access policies and audit logging across the services that agents connect to, so agents can act on a user's behalf without mishandling credentials.
Key capabilities
Alter manages OAuth credentials and automates token refresh, enforces fine-grained per-agent access policies, and evaluates each request for identity, scope and rate limits under a zero-trust approach. It logs every API call and agent action for auditability, and provides Python and TypeScript SDKs with matching interfaces, an embeddable OAuth consent widget, a developer dashboard and an end-user portal for managing connections. The platform supports 100+ SaaS providers including Google, Slack, GitHub, Salesforce, Notion and Linear.
Who it's for
Alter is built for teams building AI agents, chatbots and MCP servers, and for enterprises that need scoped access and audit trails when agents touch third-party APIs.
