  "body": "Picture this: your team wants an agent to handle routine identity chores. Look up a user, check a group, maybe move someone along when they change roles. The tool is Okta's open-source MCP server, which lets agents run Okta management operations through Okta's Admin Management APIs. Before you switch it on, you want to know what you are actually giving away.\n\nBarndoor has written a gating plan for exactly that server, and it walks the real thing. Each tool maps to a minimum OAuth scope, and tools you have not granted are removed at startup. So if you grant only .read scopes, you get a native read-only mode. That part is good news for you: the safest setup needs no extra product.\n\nThe catch is that scopes work per scope, not per tool. Grant okta.groups.manage and you unlock group membership changes and group deletion together. Barndoor puts it this way: \"OAuth scopes limit which API the agent can call. They don't describe intent.\" You might want the first and never the second, and the scope will not let you say so.\n\nThe post names three risks, and they are the ones that make an identity provider different from a CRM. The first is privilege escalation through group membership. The second is persistence, through changes that survive a password reset. The third is accountability diffusion: the Okta System Log records the client, not the person who asked or the prompt that drove the action. If something goes wrong, you can see that the agent did it. You cannot see who sent it.\n\nSo the plan sorts the work into three buckets. Read lookups are allowed, with redaction. Lifecycle and membership changes are held for a named approver. Every policy write is denied. It also tells you to deny admin role grants and token creation by name, even though the server does not expose them yet. The reasoning is blunt: \"An agent should never be able to change the rules that govern agents.\" The post notes there are no vendor figures here, and its analysis checks out against the server as described.\n\nNow the turn, because you should read this with one eyebrow up. The hold and the log both need something sitting in the path, and Barndoor sells that something. The catalog shows what it ships for it. Barndoor has 13 API pages. The Policies API is where the allow-hold-deny buckets would live. The MCP Proxy API is the runtime path every call would cross. The Agents API registers the agents the post wants identified, and the Connections API brokers OAuth connections to systems like Okta.\n\nThen the catalog turns the lens on Barndoor itself. Its agentic access profile records 26 operations: 13 acting, and just one human-in-the-loop. That single operation is the catalog's count of the hold bucket on Barndoor's own surface. Barndoor holds a Kin Score of 54.7, rated strong, with discoverability at 75.0 and contract governance at 27.3. Agent Readiness is 34.8, agent-ready, with the MCP server, auth clarity, error semantics and OpenAPI examples lit.\n\nTwo things are not lit: delegated identity and consent identity. That is the very gap the post is most persuasive about, an action that cannot be traced back to the person who asked for it. The plan for Okta is sound, but Barndoor's own contracts do not yet describe whose authority an agent is acting on.\n\nWhat you take away is practical. Start with read-only scopes, since that costs you nothing. Treat per-scope grants as coarser than your intent, and put approval in front of membership and lifecycle changes. Deny policy writes outright. And when any vendor tells you its product closes the accountability gap, check whether its own published contracts show who the agent is acting for.\n\nRead the original: https://apis.io/2026/10/29/barndoor-sorts-oktas-mcp-tools-into-allow-hold-deny/",
