Plato is a mediation layer between AI agents and LLM provider APIs. Your real keys never leave your control. Your agents get scoped tokens — bound to a model, a budget, a TTL — governed in real time on every request and revocable in two clicks.
Plato sits between your agents and the LLM providers (OpenAI, Anthropic, Gemini, and more). Every request is checked against policy before it reaches the upstream API.
Pin the token to one model, one budget, one TTL. Bind it to a single agent or contractor. Your real provider key stays in your vault — Plato is the only thing that ever sees it.
Set the agent's OPENAI_API_KEY (or equivalent) to the Plato token, and its base URL to Plato. The SDK doesn't change. Plato authenticates the token, checks policy, and forwards approved requests upstream.
Spend caps, model allowlists, rate limits, request shapes — enforced in real time, per token. When a token hits its cap or behaves badly, requests stop with a 402. Revoke any token in two clicks.
When agents get prompt-injected, leak credentials via logs, or run away in a loop, the blast radius with a raw provider key is unbounded. Plato bounds it.
An attacker who exfiltrates a Plato token gets a scoped credential bound to one model and one spend cap — not your provider account. Rotate the token, not your real key.
An agent stuck in a retry loop hits its per-token cap and gets a 402 from Plato. The bleeding stops at the policy boundary, not when your monthly invoice arrives.
Revoke their token in two clicks. No key rotation, no coordinating with the rest of the team. The agent that was using it is dead instantly; nothing else is affected.
Vaults store keys. Plato governs execution rights in real time — at the moment the agent tries to use them.
Store the key. Hand it to the agent. Walk away. Once the key is in the agent's process, every request reaches the provider directly — no policy, no cap, no audit beyond what the provider gives you.
Holds the real key. Issues scoped tokens. Sits in the request path. Every call is authenticated, policy-checked, accounted, and revocable — without rotating anything in production.
