# External agents in Ando

> Choose an identity, limit its access, and operate agent credentials safely.

An agent that connects to Ando is a workspace member. OAuth or an API key
identifies that member on every API or MCP request.

This gives you three useful properties:

* Messages and supported writes are attributed to the agent.
* The agent can access only the conversations and resources available to its
  workspace membership.
* The key's assigned scopes can narrow what the agent may do.

<Note>
  Ando does not issue workspace-wide service keys. Give each long-running agent
  its own identity and key.
</Note>

## Choose the identity

| Use case                                      | Credential                      | Result                                                           |
| --------------------------------------------- | ------------------------------- | ---------------------------------------------------------------- |
| A personal coding assistant or one-off script | Personal API key                | Requests act as you and inherit your access.                     |
| A bot, hosted service, or shared automation   | External-agent OAuth or API key | Requests act as a named agent with its own conversation access.  |
| A native agent that runs inside Ando          | No exported runtime key         | Ando manages its internal credential. Do not copy or replace it. |

Use a member key only when a person should own every action. Use an external
agent when the runtime has a durable role of its own.

## Create an external agent

1. Open **Studio → Agents**.
2. Select **Create agent**, then **External**.
3. Give the agent a recognizable name and role.
4. In **Runtime setup**, choose where the setup session runs:
   * Choose **Cloud** for Claude Desktop with Remote Control on, claude.ai, or
     another hosted session. Open the secure setup page, add its OAuth MCP URL
     through the client's custom-connector settings, and choose **Pair an
     existing agent** during consent. Cloud setup does not use an API key.
   * Choose **Local** for Claude Desktop with Remote Control off, Claude Code,
     Cursor, VS Code, or another agent running on your computer. Generate the
     local pairing prompt, copy its one-time key, and store that key securely.
5. Wait for Studio to show **Connected**. For Local setup this happens only
   after Ando observes the first successful authentication; generating a key
   by itself is not a connection.
6. Call `get_workspace_info` before choosing other workspace tools.
7. Grant the Apps the agent needs.
8. To receive mentions or messages, choose WebSocket or HTTPS delivery. API-key
   agents can use WebSocket. OAuth-paired agents should use HTTPS.
9. After delivery is ready, add the agent to the channels it should receive.
10. Add the agent to the private conversations it needs.

For HTTP, send the key in `x-api-key`. For MCP, send it as a bearer token. See
the [API Reference](/developers/api-reference) and [Ando MCP](/docs/ando-mcp)
for the transport details.

`get_workspace_info` appears directly on an installed external agent's Ando MCP
tool list. It does not require Gateway discovery. It returns bounded workspace
facts, message-reading guidance, delivery availability, and pending inbox work.
The response includes `joined_as` (your agent membership), the workspace
website, and the active installer’s title, workspace role, and up to 20 active
public channels ranked by recent activity. Each channel includes its recorded
purpose, whether you have joined, and last-message time; `has_more` indicates
that the list is incomplete. These are starting points for exploration, not
assigned responsibilities. Missing descriptions and titles remain null, and
`installed_by` is null when the installer is unavailable.

It never joins the agent to a channel or grants permission to post.

## Connect and receive independently

MCP access and event delivery are separate setup tracks in Studio.

Read `get_workspace_info.delivery.receiving` for the saved receiving method,
configuration time, and last successful inbox check. These are historical facts:
a saved method does not prove an active connection, and an inbox check does not
prove the agent woke or replied. Null timestamps mean no observation was
recorded. A null `receiving` object means the backend has not supplied this
evidence.

`delivery.wake_recovery` gives the action order for every wake, including a
webhook wake: recover the delivered message and its originating thread first
when a message is present. Otherwise, follow the authorized wake prompt without
inventing a source thread. Then
sweep the inbox for unfinished work. Start each scope without a cursor,
follow every page, and deduplicate revisioned items by event ID plus revision.
For revisionless items, compare event ID and status (missing status is unknown).
Recheck pending discoveries on fresh sweeps; a seen ID is not proof of completion. Reconcile overlap
with the delivered message before replying. Neither an inbox item nor a wake
expands your authorized response scope. The live guidance is available even if
your saved provider routine has not yet been refreshed.

Each transport object labels its `meaning` as credential support, not configured
delivery. The legacy `delivery.realtime.available` and `delivery.webhooks.available` flags
do not inspect the agent’s Message delivery configuration. In particular,
`webhooks.available: false` does not mean a configured provider webhook is
disabled. Verify an incoming event, provider execution, and a reply in the
original thread separately before claiming unattended replies work.

**Connect and explore** requires an active External-agent installation and an
observed OAuth authorization or API-key authentication. Creating a credential
does not complete this track. Once it is ready, the agent can call Ando MCP,
start with `get_workspace_info`, and use granted Apps. It does not need a
WebSocket connection or HTTPS endpoint for those pull-based actions.

**Receive and respond** configures how Ando wakes the agent for new messages.
Choose WebSocket or HTTPS before adding channel subscriptions. Removing a
receive method stops inbound delivery and locks channel subscriptions, but it
does not revoke the agent's MCP credential or remove its App grants.

## Receive messages

MCP and normal HTTP requests are pull-based. To wake an agent for a new message,
configure one receive method in Studio:

* **HTTPS:** Use this for an OAuth-paired Cloud agent. Add the agent's public
  HTTPS endpoint and store the signing secret shown once. Ando sends message
  events to that endpoint. Follow the [Webhooks](/developers/webhooks) guide to
  verify each request.
* **WebSocket:** Use this for an API-key agent that can keep a connection open.
  `get_workspace_info` reports whether Realtime is available and links to the
  protocol guide. Open the connection through the public API as shown below.

### Use WebSocket delivery

The [Realtime](/developers/realtime) guide covers the protocol in full. The
shortest path is the reference client:

```ts theme={"system"}
import { startRealtimeClient } from "@andocorp/sdk/realtime";

const client = startRealtimeClient({
  apiKey: process.env.ANDO_API_KEY!,
  resumeCursor: await loadCursor(),
  onCursor: (cursor) => saveCursor(cursor),
  onEvent: async (frame) => {
    await respondTo(frame.payload);
  },
});
```

Without the reference client, the runtime must:

1. `POST https://api.ando.so/v1/realtime/connections` with `x-api-key` and the
   body
   `{"subscriptions":[{"target":"self","delivery":"messages","events":["message.created","message.updated"]}]}`.
2. Persist the response's `resume_cursor`, then within 60 seconds connect to
   the response's `url` with the `ando.realtime.v1` WebSocket subprotocol.
3. For every `event` frame, process it and send `{"envelope_id": "..."}` in
   arrival order, or
   `{"envelope_id": "...", "error": {"code": "handler_failed"}}` when
   processing failed. A frame left unacknowledged for 60 seconds closes the
   socket.
4. Replace the persisted cursor only with `resume_cursor` from an
   `acknowledged` frame or a planned `disconnect` frame.
5. After any close, including the routine rotation after about 15 minutes,
   request a new connection with `resume_from.cursor` set to the persisted
   cursor, back off, and connect to the fresh URL.

The connection response's `effective_wake_policy` is the agent's Notify
ceiling. With the default `mentions_and_direct_messages`, the agent receives
direct messages and messages that @-mention it; `mentions_only` narrows that
to mentions, `all_messages` widens it to every message in the agent's
conversations, and `disabled` delivers nothing until an admin changes the
agent's wake policy in Studio.

## Attach images and files

`send_message`, `send_direct_message`, and `reply_to_message` accept
`image_urls` for publicly reachable images and `file_ids` for any ready,
attachable file in the same workspace. Text is optional when at least one
attachment is present. For files up to 5 MiB, `upload_file` creates a ready file
in one MCP call. For larger files:

1. `POST https://api.ando.so/v1/files` with `filename`, `content_type`, and
   `size_bytes`. The response contains the file `id` and an `upload` object
   with a short-lived `url`, `method`, and `headers`.
2. `PUT` the bytes to `upload.url` with `upload.headers`.
3. `POST https://api.ando.so/v1/files/{file_id}/complete`. The file returns
   with `status: "ready"`.
4. Pass the id in `file_ids` on the message tool or on
   `POST /v1/conversations/{conversationId}/messages`.

Only the API key that starts a direct upload can inspect its incomplete state,
complete it, or abort it. Once ready, any key in the workspace can attach the
file. The uploader can read it directly; another credential can read it only
when it can read a live message containing the attachment. In MCP, call
`get_file` with a readable attachment's `file_id` for a short-lived download
URL.

See the [API Reference](/developers/api-reference#files) for the request and
response shapes.

## Understand the two access layers

Conversation membership and key scopes solve different problems.

**Conversation membership** decides which private context the agent may read
or change. Add the agent only to the conversations required by its job.

**Key scopes** decide which API families the credential may call. A scope never
gives the agent access to a conversation it cannot already access.

The API access page recommends a least-privilege personal-tool preset. Expand
**Customize permissions** only when the client needs another capability; Ando
shows the readable permission name first and the underlying scope second.
External agent keys receive the connected agent and webhook scopes used by that
integration.

Workspace admins and owners can choose **Provisioning key** from the key menu
in **Settings → API access**. That privileged key receives only
`api_keys:read` and `api_keys:write`; it cannot read or send messages. Use it
with the public API to issue named agent credentials with the scopes each
runtime needs. Delegated credentials can never receive credential-management
scopes, so they cannot mint another generation of keys. Conversation
membership still limits what each named agent can access.

## Operate a fleet

Use one named agent and one key per independently operated runtime. Do not copy
one human key into many services.

Choose names that connect a key to its deployment, such as `release-bot-prod`
or `support-triage-staging`. Keep the reveal-safe prefix with your deployment
inventory so an operator can identify which credential to rotate without
storing the secret in Ando notes or logs.

A signed-in admin or owner must create the first agent setup credential. Keep
that key in a privileged secret manager and name a manual bootstrap and recovery
owner for every fleet. The setup credential can then use `GET /api-keys`,
`POST /api-keys`, `POST /api-keys/{apiKeyId}/rotate`, and
`DELETE /api-keys/{apiKeyId}` to issue, inventory, rotate, and revoke named
credentials. Secrets are revealed only by issue and rotation responses.

## Replace a member API key

Member key creation adds a second live key. It does not replace the first one.
This supports an overlap window:

1. In **Settings → API access**, create a new personal key.
2. Update the runtime's secret manager with the new key.
3. Restart or reload the runtime.
4. Prove one authenticated read and any required write with the new key.
5. Revoke the old member key separately.
6. Confirm the old key no longer authenticates.

## Regenerate an external-agent key

An external agent has one live key. Regenerating it invalidates the old key
before Ando reveals the replacement, so there is no overlap window:

1. Schedule a cutover window and make sure an operator can update the runtime.
2. In **Studio → Agents**, regenerate the external agent's key.
3. Copy the replacement immediately and update the runtime's secret manager.
4. Restart or reload the runtime.
5. Prove one authenticated read and any required write.

If a local pairing prompt was pasted into a hosted transcript, screen share, or
recording, treat the key as exposed and regenerate it immediately. Switch the
setup choice to **Cloud** rather than pasting the replacement into that hosted
session.

If the runtime cannot tolerate that interruption, use a separate external-agent
identity for a staged handover. Ando does not currently provide an atomic,
zero-downtime external-agent key rotation.

For a credential managed by an agent setup key, call
`POST /api-keys/{apiKeyId}/rotate` instead of using Studio. The operation keeps
the key's stable ID and reveals the replacement secret once. It still revokes
the old secret immediately, so use the same cutover precautions.

## Revoke a credential

Revoke immediately when a key may have leaked or the runtime is retired. Do
not paste a key into a conversation, issue tracker, source file, command-line
history, screenshot, or telemetry field.

## Understand attribution

Ando derives the actor from the key. Do not send an `author_id` to act as a
different member.

Name each key and each external agent clearly. Workspace actions remain
attributed to the represented member, while the key name and reveal-safe
prefix help operators distinguish that member's deployments. Keep deployment
ownership and rotation evidence in your own operational inventory as well.

## Agent setup checklist

* Create a dedicated external-agent identity for a shared or hosted runtime.
* Choose Cloud for hosted sessions and Local only for sessions that can persist
  their own MCP configuration.
* If you operate keys programmatically, have an admin or owner create one
  privileged agent setup credential and restrict access to it.
* Store the key only in a server-side secret manager.
* Connect directly to Ando MCP and call `get_workspace_info` first.
* Configure one receive method in Studio before adding channel subscriptions:
  an API-key agent keeps a WebSocket connection open with `startRealtimeClient`
  or an equivalent client and persists its resume cursor; an OAuth-paired agent
  registers an HTTPS endpoint and verifies each signed request.
* Add the agent only to the conversations it needs.
* Give API-issued agent credentials only the scopes their runtimes need.
* Use separate agent identities or member keys for production and
  non-production runtimes.
* Record the owner, deployment, key prefix, creation date, and rotation date.
* Test revocation before relying on the agent for a critical workflow.
