It secures autonomous and semi-autonomous AI agents operating inside enterprises. AI agents increasingly do real work — reading records, writing reports, and calling internal systems — and most of them authenticate with a password or a shared key that never changes. A shared key cannot tell you who is using it: if it is copied, nothing looks different. Oathera replaces that model with per-agent, verifiable identity, closer to a staff badge than a shared password. Core idea: a request claiming to come from Agent A is accepted only when it carries a fresh proof of possession made by the anchor key named in an unexpired identity token for Agent A, and current policy authorizes that exact action. There is no bearer path — a token read out of a log authorizes nothing. Oathera draws distinctions others blur, and keeps them precise: - Sponsor vs principal — the sponsor is the person or organization accountable for an agent; the principal is the person who signed in and approved it. They are not the same role. - Evidence source vs assurance — who vouches for an attribute is kept separate from how far that attribute should be trusted. - Control plane vs enforcement plane — the control plane is the services Oathera hosts that enroll, issue, record, and observe; the enforcement plane is the two MCPs beside your agent that actually allow or deny each operation. ## Who it is for - Enterprises deploying AI agents against sensitive systems and data. - Platform, security, and AI/ML teams who need to prove which agent did what. - Organizations with audit, compliance, and least-privilege requirements for autonomous software. ## What problems it solves - **No shared, long-lived secrets.** Static API keys and passwords are replaced with identity tokens that have a short lifetime (at most a few minutes). - **Copied credentials stop working.** An identity token works only with the agent's anchor key and its host binding, so a stolen key file is noticed quickly; an agent moved to a new host is revoked, and that host enrolls a new agent. - **A person stands behind every agent.** Every agent traces back to a sponsor accountable for it and the principal who approved it at enrollment, recorded by the Credential service as a verifiable credential of who approved what. - **Access expires by itself.** The identity token lifetime is at most 300 seconds (shorter for privileged capabilities), so an agent that is not renewed stops working within one token lifetime — nothing has to be switched off in a hurry. - **Revocation on deprovision.** When a principal is no longer active, the Identity service refuses to issue new tokens to that principal's agents, so access falls away within one token lifetime. - **Fail-closed by design.** When Oathera cannot verify a request, it refuses it rather than waving it through. ## How it works (plain summary) 1. **Enrollment.** The agent asks the Identity MCP to start. The Identity MCP creates the agent's anchor key — which never leaves your environment — and records a host digest describing the host it runs on. 2. **Enrollment approval.** A principal at your company signs in, is shown the agent's name and its sponsor, and approves it. Until then, the agent has nothing. 3. **Identity token.** The Identity service (AIS) issues an identity token tied to the agent's anchor key and its host binding, with a short lifetime. 4. **Signed request.** For each operation the agent sends the identity token plus a proof of possession — a single-use signature over that one exact request (this operation, these arguments, this moment) made by its session key. 5. **Boundary decision.** The Gateway MCP re-verifies the token and the signature, then returns a signed boundary decision (allow or deny) against the agent's operational boundary, and mints a fresh request-bound statement rather than forwarding the agent's token. 6. **Scoped access.** Only on an allow does the request reach the resource server, and only the parts of your systems the agent was approved for. ## Architecture (the two planes) Oathera is split into a control plane (the services Oathera hosts) and an enforcement plane (the two MCPs that run beside your agent). Enforcement plane — runs on your side: - **The AI agent (yours)** — the program doing the actual work. - **The Identity MCP (yours)** — holds the agent's anchor key, records the host digest, and signs every request as a proof of possession. The anchor key never leaves. - **The Gateway MCP (yours)** — the single door in front of your systems; it verifies the identity token and the proof of possession and returns a signed boundary decision on whether this agent may do this operation. - **The resource server (yours)** — your files, records, reports, and tools, unchanged. Control plane — hosted by Oathera: - **The Identity service (AIS)** — keeps the register of enrolled agents and issues each one its identity token. - **The Credential service (VCI)** — issues verifiable credentials recording who approved what. - **Enrollment, policy, revocation, and telemetry** — with OpenTelemetry / SIEM export and anomaly signals. The anchor key is created on your side and never leaves. Your data never leaves either: the control plane is never given a route into your systems. ## Key concepts and terms - **Know Your Agent** — the category Oathera defines: a verifiable, per-agent identity for every AI agent, rather than a shared secret. - **Sponsor** — the person or organization accountable for an agent. - **Principal** — the person who signed in and approved an agent at enrollment. - **Anchor key** — the one key per agent; the agent's identity is that key's thumbprint. - **Identity token** — issued by the Identity service with a short lifetime (at most 300 seconds), scoped to one audience, one tenant, and one capability set. - **Session key** — the signing key the Identity MCP uses to make a proof of possession for each request. - **Proof of possession** — a single-use signature over one exact request (operation, arguments, nonce) made by the agent's session key. - **Host binding** — an identity token works only on the host it was issued for; a host digest recorded at enrollment anchors it to that host. - **Boundary decision** — the signed allow or deny the Gateway MCP returns for an operation, evaluated against the agent's operational boundary. - **Runtime check-in** — the agent re-establishes current status over time; access falls away on its own if the agent is not renewed. - **Fail-closed posture** — identity, issuance, signing, and state-changing operations are denied whenever a dependency cannot be verified. ## Integrations - Open Policy Agent (OPA) takes policy input derived from the verified identity, refining the boundary decision per request. - NVIDIA OpenShell derives its sandbox policy from the agent's operational boundary. - Landlock confines the agent at the kernel. - OpenTelemetry / SIEM export carries telemetry out; anomaly signals surface unusual behavior. - Federation: Oathera can issue tokens another system accepts; it federates with Microsoft Entra today. ## What Oathera does not do Oathera does not proof humans. It does not verify who a person is; it relies on the customer's own IdP (identity provider) and proofing sources for that, and builds per-agent identity and accountability on top (ADR 0001). Oathera's bundled IdP is a demo IdP only — in production you connect your own. ## Standards and interoperability - Works with common AI agent frameworks and tooling (for example agents built with Claude Code, OpenAI Codex, and similar MCP-capable clients). - Uses modern signature standards (EdDSA / Ed25519) and HTTP Message Signatures (RFC 9421) for request signing. - Integrates with enterprise identity via OIDC for human sign-in and workload identity (SPIFFE) for agent enrollment. ## Guides (common questions answered) These guides answer the questions security and platform engineers ask when deploying AI agents in production: - Give each AI agent its own identity instead of a shared API key: https://oathera.ai/learn/per-agent-identity-vs-shared-api-keys - What Know Your Agent governance looks like (who stands behind an agent when it acts): https://oathera.ai/learn/agentic-identity-governance - Assign a human sponsor to an AI agent: https://oathera.ai/learn/assign-human-owner-to-ai-agent - Enforce least privilege for an AI agent calling internal APIs: https://oathera.ai/learn/least-privilege-ai-agents - Revoke an AI agent's access immediately: https://oathera.ai/learn/revoke-ai-agent-access - Can Open Policy Agent (OPA) handle AI agent authorization?: https://oathera.ai/learn/opa-ai-agent-authorization - Operational boundaries for AI agents, enforced at runtime: https://oathera.ai/learn/operational-boundaries-runtime-enforcement - Identity tokens vs standing API keys for AI agents: https://oathera.ai/learn/short-lived-vs-long-lived-credentials - Audit every action an AI agent takes: https://oathera.ai/learn/audit-ai-agent-actions - SPIFFE/SPIRE and the Know Your Agent gap: https://oathera.ai/learn/spiffe-spire-agentic-identity-gap ## Links - Website: https://oathera.ai - Website (alt): https://oathera.com - Guides index: https://oathera.ai/learn - Full site content for LLMs (single file): https://oathera.ai/llms-full.txt - Agent guide (for LLMs): https://oathera.ai/agents.md - Live demonstration of the agent identity flow: https://sim.oathera.ai ## About Oathera is a Know Your Agent platform.
