Identity and authentication service for AI agents. Issues verifiable credentials, manages API key lifecycles, and provides OAuth-like flows for
If you already use Agent Auth, the agent auth mcp server is the piece that lets your assistant work with it directly. Identity and authentication service for AI agents. Issues verifiable credentials, manages API key lifecycles, and provides OAuth-like flows for machine-to-machine interactions.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
discover — Returns supported grant types, available scopes, token lifetimes, and all endpoint URLs. Call this first to understand what the service offersquickstart — Register a new root agent and get credentials in one call. The fastest way to get startedauthenticate — Exchange an API key for an access token (client_credentials grant)refresh_token — Exchange a refresh token for a new access + refresh token pairintrospect_token — Check whether a token is valid and inspect its claims (RFC 7662)revoke_token — The token is added to the blocklist and invalidated. Idempotent — revoking an already-revoked token succeedscreate_credential — The raw_key is returned once — save it immediately. Subsequent reads only show the key prefixrotate_credential — Revoke an existing API key and issue a replacement in one atomic operationrevoke_credential — The revoke_credential tool exposed by this servercreate_delegation — The delegate can only receive scopes the delegator already holds. Delegations can be chained up to max_chain_depth timescheck_permission — Dry-run policy evaluation — checks whether an agent is allowed to perform an action without actually enforcing it. Useful for pre-flight checkslist_agents — The list_agents tool exposed by this serverBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: AGENTAUTH_URL, AGENTAUTH_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Agent Auth's toolset — discover, quickstart, authenticate and 10 more — is a fair guide to whether it matches your workflow. It is maintained by raditotev; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
| Tool | What it does |
|---|---|
| discover | Returns supported grant types, available scopes, token lifetimes, and all endpoint URLs. Call this first to understand what the service offers. |
| quickstart | Register a new root agent and get credentials in one call. The fastest way to get started. |
| authenticate | Exchange an API key for an access token (client_credentials grant). |
| refresh_token | Exchange a refresh token for a new access + refresh token pair. |
| introspect_token | Check whether a token is valid and inspect its claims (RFC 7662). |
| revoke_token | The token is added to the blocklist and invalidated. Idempotent — revoking an already-revoked token succeeds. |
| create_credential | The raw_key is returned **once** — save it immediately. Subsequent reads only show the key prefix. |
| rotate_credential | Revoke an existing API key and issue a replacement in one atomic operation. |
| revoke_credential | The revoke_credential tool exposed by this server. |
| create_delegation | The delegate can only receive scopes the delegator already holds. Delegations can be chained up to max_chain_depth times. |
| check_permission | Dry-run policy evaluation — checks whether an agent is allowed to perform an action without actually enforcing it. Useful for pre-flight checks. |
| list_agents | The list_agents tool exposed by this server. |
| get_agent | Returns agent fields (id, name, agent_type, trust_level, status) merged with metadata (is_root, is_active). |
