Keycard

What is Keycard?

Keycard is runtime authorization infrastructure for AI agents. It gives each agent its own identity and decides, at the moment of each request, whether the agent can access a resource.

Key capabilities of Keycard

• Agent identity: verifies the agent, where it runs and the human user it acts for.
• Policy as code: rules written in Cedar and managed with Terraform.
• Short-lived credentials: issues task-scoped credentials only when approved.
• Audit logging: logs events with full attribution and can revoke credentials.
• Activity views: real-time views by application, user or resource.
• SIEM export: exports to OCSF-compatible SIEMs or Amazon S3.

How Keycard works

An agent requests access, Keycard verifies its identity and context, and evaluates the request against Cedar policy. If approved, it issues a short-lived credential scoped to the task; if denied, no credential is issued and the decision is logged. Enforcement runs through an SDK, a gateway or a sidecar proxy.

Who uses Keycard?

Keycard is for developers building agents, MCP servers and internal tools, and for platform, security and AI operations teams moving agents into production.

Keycard pricing

Keycard does not list pricing on its main page and links to a separate pricing page.

Keycard alternatives

Abstract Security is a security data and detection platform, so it works on logs and threats rather than agent access. Doppel focuses on defending against social engineering and impersonation. Resolve.ai is an AI agent for production incident response. Keycard differs by controlling what agents can access at runtime.
