Built for Both Sides of the Agent Stack

Whether You Deploy Agents or Host What They Access

Agent Operators

If You Deploy AI Agents

Your agents are making API calls, accessing data, and spending money on your behalf. Without trust infrastructure, you have no way to know what they're doing — and no way to stop them when they go wrong.

Modei gives every agent a cryptographic identity with built-in limits. You define what's allowed, and the infrastructure enforces it — before damage is done, not after.

Service Providers

If You Run APIs, MCP Servers, or Tools

You're exposing APIs and services to AI agents you didn't build and don't control. You need to verify who's calling, what they're allowed to do, and optionally meter and bill for usage.

Modei lets you require cryptographic proof of identity and authorization on every request — and gives you the metering and settlement infrastructure to monetize agent access.

How It Works

Start in Minutes, Not Sprints

Register Your Identity

Create your account on Modei and generate cryptographic credentials for your agents or your services.

Issue Passports or Create Gates

Deploying agents? Issue passports with scoped permissions. Hosting services? Create gates that define what’s allowed.

Connect via MCP or API

Plug in with the TypeScript or Python SDK. Modei is MCP-native — it works with Claude, GPT, and any MCP-compatible host.

Every Action Signed & Verified

From this point forward, every agent request is verified, every decision is signed, and every action is recorded.

Integrate in Minutes

Whether you're deploying agents or protecting services, Modei plugs into your stack with a few lines of code.

What's Inside

Six Pillars of Trust

Passports

Cryptographic identity bound to what the agent actually is — model, version, architecture. Not just who operates it. Issue in seconds. Verify in under a millisecond. Delegate with guaranteed attenuation.

Gates

Policy enforcement where it matters — between the agent and the resource. Permission catalogs, spend limits, rate controls, domain allowlists. Credentials pinned to specific catalog versions so terms can’t change without your awareness.

Enforcement

Decisions made before damage is done. Spend limits enforced at the gate, not tracked after. Revocation propagated in real time, even mid-execution. Four-decision model: permit, block, suspend, or output-hold.

Supravision

Human oversight when it matters. When an agent hits a decision that needs a human, you get an SMS. Reply YES or NO directly from your phone — no app required. Emergency stop from the dashboard. Every approval recorded as a signed attestation.

Audit

Every action produces a signed receipt. Every receipt is hash-linked to the last. Both sides hold a copy. Gaps are detectable. Tampering is evident. Export the whole chain for compliance, accounting, or regulatory review.

Commerce

Infrastructure for agent-to-agent transactions. Services publish signed catalogs with pricing and terms. Agents discover, compare, and transact — with pricing locked to their credential and every transaction producing a cryptographically verifiable receipt.
