Ory Agent Extension: Gemini CLI

Ory bundled into Gemini CLI: skills and TOML slash commands that scaffold Ory authentication into your codebase, a local Ory stack you can spin up in one command, and (when pointed at an Ory project) authentication, authorization, and audit for every tool Gemini runs.

You don't need an Ory account or any prior Ory experience to start.

Prerequisites

• Gemini CLI installed and signed in
• Node.js ≥ 22
• Docker (only needed for the local Ory stack)
• macOS or Linux. Windows works via WSL2.

Install

In your shell:

gemini extensions install https://github.com/ory/gemini-cli-extension

Then confirm everything landed:

npx -y -p @ory/gemini-cli ory-gemini status

status is the single source of truth — it prints configuration, user and agent identity, per-tool permission coverage, extension + skill registration, and a tail of recent debug logs. Unconfigured fields show inline as (unset).

Alternative install paths

npx -y @ory/gemini-cli install
npx -y @ory/gemini-cli uninstall

If the gemini binary isn't on your PATH, npx -y -p @ory/gemini-cli ory-gemini-setup writes the extension config directly into your project's .gemini/settings.json.

Quickstart (≈ 3 minutes)

From any project where you'd like Ory authentication, inside Gemini CLI:

1. Start a local Ory instance. Ask Gemini "start the local Ory stack" or run:

   /ory:local-up
   

   A banner prints the seeded test user's email and password. Note them — you'll log in with them in step 3.

2. Scaffold Ory into your project. Ask Gemini "add Ory auth to this app" or invoke the ory-auth-setup skill.

   Gemini installs Ory Elements, wires the SDK, generates the login / registration / recovery / verification / settings pages, and sets up session middleware. It targets the local stack from step 1, so no signup or API key is needed.

3. Sign in. Start your app, visit the login page Gemini added, and sign in with the seeded credentials. You now have a real Ory session backed by a real Ory stack — locally, offline, with zero configuration.

4. Turn on Ory login for the Gemini session itself. (Optional but recommended.) Out of the box the extension only governs your app. To also attach an Ory identity to Gemini's session — so every tool call is attributed to you, not a fallback session:<id> subject — opt in to the user-login flow:

   export ORY_USER_LOGIN=true
   export ORY_OAUTH2_CLIENT_ID=<value printed by `local up`>

   User login is off by default. Both exports above are printed in the local up banner — copy them straight from there. ORY_OAUTH2_CLIENT_ID is required whenever ORY_USER_LOGIN is on: it identifies the public OAuth2 client the PKCE browser flow exchanges for a token. With both set, the next Gemini session opens an Ory login in your browser; sign in with the same seeded credentials from step 1, and the token is reused on subsequent sessions until it expires. This is what makes permissions enforce (see Agent security) deny on the right identity later.

That's the full Ory DX path. Stop here if you're just evaluating the extension. Continue to Agent security when you're ready to enforce.

What's included

Skills for scaffolding Ory into your application

The extension bundles a catalog of skills that Gemini auto-invokes by description. Ask Gemini in natural language or invoke a skill directly:

• ory-auth-setup — full project setup. Install the Ory CLI, create an Ory Network project (or use the local one), add Ory Elements, configure the SDK, build the auth pages, wire session middleware.
• ory-login-flow — login, registration, recovery, verification, and settings pages with Ory Elements. Next.js App Router and React SPA variants.
• ory-social-login — Google, GitHub, Apple, Microsoft, Discord, and other OIDC providers with Jsonnet data mappers.
• ory-local-dev — drive the local Ory stack from within Gemini to prototype and test without a remote project.
• ory-permissions-onboarding — bootstrap permission tuples for built-in tools, switch between observe and enforce mode, troubleshoot denials.
• ory-build-integration — pull the runnable subset of an ory/integrates template (webhook / config / http-event) into your own app and wire it to your Ory project — no contribution/registry concerns.
• ory-contribute-integration — author a brand-new integration as a contribution to ory/integrates, including registry.entry.yaml, the Maintained by: footer, DCO sign-off, and registry regeneration.
• ory-e2b-sandbox — scaffold an E2B sandbox template that boots with this extension preinstalled and registered, so every sandbox session is gated by Ory auth, permissions, and tracing without any per-sandbox setup.
• ory-build-agent — drop @ory/argus directly into a custom agent you own (Claude Agent SDK, OpenAI Agents SDK, Mastra, Vercel AI SDK, PydanticAI, LangGraph, Mistral AI, or Salesforce Agentforce) so the user is authenticated, every tool call is authorized against Ory Permissions, and the lifecycle emits trace spans.
• ory-temporal-worker — scaffold a Temporal TypeScript worker per the official local-dev guide, with every Activity gated by an Ory permission check, the worker's agent identity resolved via DCR, and the full lifecycle emitting trace spans.

Ory MCP server

Bundled and registered automatically. Exposes the Ory CLI and the Ory Network REST API as MCP tools so Gemini can manage identities, OAuth2 clients, projects, permission tuples, and configuration without ever leaving the chat. Useful for seeding test data, verifying a scaffolded integration, or running one-off admin tasks.

Local Ory stack

/ory:local-up      # start a local Ory instance in Docker
/ory:local-down    # tear it all down
/ory:temporal-up   # start a local Temporal dev server (for ory-temporal-worker)

local-up brings up Ory Identities, OAuth2, and Permissions, plus a login UI on :3000 and Jaeger on :16686, all reachable through http://localhost:4000. A test user identity is seeded and the credentials are printed for you. Use it to:

• Learn Ory hands-on without signing up for a hosted project.
• Prototype flows (login, social, MFA, recovery, permission tuples) against a real Ory backend.
• Test an auth integration end-to-end before pushing anything to a real environment.
• Develop your application against the same identity, OAuth2, and permission surfaces you'll ship with.

Pointing at a real Ory project

The Quickstart uses the local stack. If you have a hosted Ory Network project, point the extension at it with a single configure command. The extension requires --oauth2-client-id whenever --project-url is provided — register the client first (see Register the user OAuth2 client below), then run:

npx -y -p @ory/gemini-cli ory-gemini configure \
  --project-url https://<id>.projects.oryapis.com \
  --oauth2-client-id <public OAuth2 client id>

• --project-url points the extension at your project. The agent identity (machine credentials for Gemini's outgoing Ory API calls) is created automatically on first run via OAuth2 Dynamic Client Registration (RFC 7591) against the project's /oauth2/register endpoint — no manual step required for that one.
• --oauth2-client-id is required because the user PKCE browser flow (triggered by ORY_USER_LOGIN=true) cannot self-register — you must register a public OAuth2 client ahead of time and supply its id here. The configure command refuses to save a project URL without it, so you don't end up with a silently-broken setup later. See Register the user OAuth2 client below for the exact CLI / Console steps.
• --api-key ory_pat_... is optional — pass it only if you want to override the auto-registered agent identity with a static personal access token (operator override; rarely needed).

If you only want audit logging (no auth or permission checks), substitute --audit-only — the OAuth2 client id is not required in that mode:

npx -y -p @ory/gemini-cli ory-gemini configure --audit-only

The same settings can be supplied via environment variables (ORY_PROJECT_URL, ORY_OAUTH2_CLIENT_ID, ORY_AGENT_API_KEY) — env vars take precedence over the config file when both are set, which is what most CI / scripted setups want.

Config is saved to ~/.config/ory-agent-plugins/config.json and shared across every Ory agent plugin or extension on the machine.

Without configuration the extension still loads cleanly and runs in pass-through mode: skills and commands work, but nothing is blocked. You can stay in pass-through mode indefinitely if you only want the DX features.

Register the user OAuth2 client

If you plan to turn on ORY_USER_LOGIN=true (recommended — it's what attributes every tool call to you rather than a fallback session:<id> subject), your hosted Ory project needs a public OAuth2 client (no client secret) registered ahead of time. The local stack provisions this for you automatically; against a hosted project you have to register it once yourself.

The client must list all four loopback ports as redirect URIs:

• http://127.0.0.1:47823/callback
• http://127.0.0.1:47824/callback
• http://127.0.0.1:47825/callback
• http://127.0.0.1:47826/callback

The extension walks the four ports at runtime so the login can survive any one of them being occupied — Ory rejects the callback if the port it lands on isn't on the registered list, so register all four.

Create the client with the Ory CLI:

ory create oauth2-client --project <project-id> \
  --name "ory-agent-plugin" \
  --grant-type authorization_code,refresh_token \
  --response-type code \
  --scope openid,offline_access \
  --token-endpoint-auth-method none \
  --redirect-uri http://127.0.0.1:47823/callback \
  --redirect-uri http://127.0.0.1:47824/callback \
  --redirect-uri http://127.0.0.1:47825/callback \
  --redirect-uri http://127.0.0.1:47826/callback

…or in the Ory Console under OAuth2 → Clients → Create client (pick "Public client", set "Authorization Code" + "Refresh Token" grants, scopes openid offline_access, paste the four redirect URIs above). Then persist the issued id with the configure command (preferred — survives across sessions):

npx -y -p @ory/gemini-cli ory-gemini configure \
  --project-url https://<id>.projects.oryapis.com \
  --oauth2-client-id <client-id from the step above>

…or set it in the environment alongside ORY_USER_LOGIN:

export ORY_USER_LOGIN=true
export ORY_OAUTH2_CLIENT_ID=<client-id from the step above>

Headless / CI runs that already hold a session token can skip this entirely by setting ORY_USER_SESSION_TOKEN instead — no browser flow runs, so no OAuth2 client is needed.

Agent security

Once the extension is pointed at an Ory project (local or hosted), Gemini's session and every tool call can be governed by Ory.

• Authentication. Two identities. The human at the keyboard (the user) authenticates interactively via Ory Identities when user login is enabled (ORY_USER_LOGIN=true, off by default — browser PKCE flow on first session, persisted token thereafter). The Gemini process (the agent) gets its own OAuth2 identity, self-registered via Dynamic Client Registration (RFC 7591) on first run.
• Authorization. Before any tool runs, the extension checks Ory Permissions (Zanzibar-style relation tuples) against the user's subject and blocks the call on deny. MCP tool calls additionally get a server-level check.
• Audit. Every decision (allow, deny, fallback) is recorded as a structured trace span: NDJSON file output and/or OTLP/HTTP export to Jaeger, Honeycomb, Grafana, and similar collectors. The user → agent delegation is written to Ory as a relation tuple so "agent X acting on behalf of user Y" stays queryable after tokens expire.

The extension is fail-open on its own infrastructure failures (network errors, rate limits, missing config), so enforcement is only as strong as your tuples — grant explicit invoke relations for the tools each user should be able to run.

Enable enforcement

After install the extension runs in observe mode: every tool call is checked against Ory Permissions, but a deny is recorded as a permission.observe_deny audit span and the tool runs anyway. This lets you see what would be blocked before turning on hard blocking.

1. Turn on user login. It's off by default. In your shell:

   export ORY_USER_LOGIN=true
   export ORY_OAUTH2_CLIENT_ID=<public OAuth2 client id>

   The next Gemini session opens a browser for PKCE login. Subsequent sessions reuse the persisted token until it expires.

   ORY_OAUTH2_CLIENT_ID is required when ORY_USER_LOGIN is on: PKCE needs a public OAuth2 client registered with the four loopback redirect URIs (http://127.0.0.1:47823..47826/callback) to exchange the authorization code for a token. The local stack provisions one and prints the export in its local up banner; for a hosted Ory project see Register the user OAuth2 client for the exact CLI / Console steps. Headless / CI runs can skip the browser flow entirely by pre-supplying ORY_USER_SESSION_TOKEN instead.

2. Bootstrap tuples for the built-in tools. One idempotent command grants the current user use on every tool Gemini ships with (read_file, write_file, shell, …):

   npx -y -p @ory/gemini-cli ory-gemini permissions bootstrap

   If a user identity is already cached at install time, the installer runs this for you automatically — re-run after adding tools, switching subjects, or changing the namespace.

3. Check coverage. permissions status probes every tool in the harness's catalog and prints allowed / denied per tool:

   npx -y -p @ory/gemini-cli ory-gemini permissions status

   Add tuples for any MCP server tools or custom commands by hand, or via the Ory MCP server from inside Gemini ("grant me use on the shell tool").

4. Promote to enforce. Once the observe-mode logs look right, switch over:

   npx -y -p @ory/gemini-cli ory-gemini permissions enforce

   Denies now block the tool call; Gemini shows the denial reason and the decision is recorded as a tool.block trace span with blocked: true. Switch back any time with permissions observe.

CLI reference

npx -y -p @ory/gemini-cli ory-gemini install                             [--link]
npx -y -p @ory/gemini-cli ory-gemini uninstall
npx -y -p @ory/gemini-cli ory-gemini configure                           [--project-url <url> --oauth2-client-id <id>] [--api-key <key>] [--audit-only]
npx -y -p @ory/gemini-cli ory-gemini agent <status|unregister>           Manage the agent's OAuth2 identity
npx -y -p @ory/gemini-cli ory-gemini permissions <status|bootstrap|observe|enforce>
npx -y -p @ory/gemini-cli ory-gemini local <up|down|status|seed|logs|env|configure|reset>
npx -y -p @ory/gemini-cli ory-gemini status

Highlights:

• agent status — show the current persisted DCR identity for the agent.
• permissions observe / permissions enforce — switch between "log denies, allow through" (the install default) and "block denies." permissions bootstrap writes use tuples for the harness's built-in tools so the promotion path doesn't require hand-writing relationships.
• configure --audit-only — kill switch that disables Ory entirely (no auth, no permission checks; only audit logging of tool invocations). For phased rollouts, prefer permissions observe over --audit-only.
• local seed / local env — reseed the test user, or print env vars for pointing other tools at the local stack.

Troubleshooting

• /ory:local-up fails. Make sure Docker is running and ports 3000, 4000, 4100, and 16686 are free.
• PKCE login loops. Clear persisted state with npx -y -p @ory/gemini-cli ory-gemini agent unregister and retry.
• npx fetches an old version. Force a fresh fetch: npx -y -p @ory/gemini-cli@latest ory-gemini ….
• Need more signal. Set ORY_AGENT_DEBUG=true and ORY_AGENT_LOG_FILE=/tmp/ory.log to capture structured logs.
