What Is Proxer?

Proxer is trust infrastructure for AI agents. It solves the fundamental problem of the agent economy: how do you verify who an agent is, what it's allowed to do, and prove what it did?

Passports give your agents verifiable credentials that prove their identity and capabilities. Gates protect your resources by checking those credentials before granting access. Guardrails enforce spending limits, rate limits, and scope rules to keep agents operating within safe boundaries. Everything is cryptographically signed with Ed25519 and auditable.

Whether you're building an agent that calls external APIs, protecting your own MCP server, or enabling agent-to-agent commerce — Proxer provides the trust primitives you need.

Core Concepts

Passport

A verifiable credential issued to an AI agent. Contains the agent's identity, permissions, constraints, and a cryptographic signature from the issuer.

Gate

A checkpoint that protects a resource or API. Verifies passports, checks permissions, enforces constraints, and produces signed attestations.

Guardrail

Constraints attached to a passport that limit what an agent can do. Includes spending caps, rate limits, domain restrictions, and approval thresholds.

Attestation

A signed proof record created when a gate evaluates a passport. Contains the decision, reason, and a verifiable signature for audit purposes.

Template

A pre-built set of constraints you can apply to passports with one click. Templates cover common use cases like financial agents, read-only access, and more.

How It Works

1

Create Credentials

Issue a passport for your agent with the permissions and constraints it needs to operate. Each passport is cryptographically signed by the issuer.

2

Set Up Protection

Create a gate on your resource or API. Configure which issuers you trust and what security level to enforce (L1, L2, or L3).

3

Monitor Activity

Watch authorization decisions in real time. Review signed attestations, adjust guardrails, and refine your trust policies as agents operate.
