## Findings

- **info** The word "credentials" in `list_channels` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...it expects. Channels and their provider credentials are set up in the Ray dashboard, not th..."
```


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `archive_template`

- The name "archive_template" says "archive": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Archive a template (POST /templates/{id}/archive; write scope). Sends that reference it fail until it is restored with unarchive_template; its name stays reserved meanwhile. Confirm with the user first if it may be in production use.
```

### `delete_webhook`

- The name "delete_webhook" says "delete": a word for removing or ending something.
- The description says "cannot be restored".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete (archive) a webhook so it receives no more events (DELETE /tenant-webhooks/{id}; write scope). It cannot be restored through the API; confirm with the user first.
```

## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `publish_template`

- The name "publish_template" says "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Publish a template's current draft as its new live version (POST /templates/{id}/publish; write scope). Sends by templateId use it immediately. Fails if there is no draft or the template is archived.
```

### `send_notification`

- The name "send_notification" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.recipient): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a notification (POST /send; needs a `write`-scoped key). Returns `{ sendId }` with HTTP 202: delivery is asynchronous, so check the outcome with get_send_status. Use exactly one mode:
1. Single: `channelConfigId` + `recipient`.
2. Fan-out: `channelConfigId` + `targets` (1-1000 `{ recipient, externalUserId? }`), one channel, one sendId.
3. Multi-channel: `deliveries` (1-10, each with its own `channelConfigId`, `recipient` and `templateId` or `content`) for ONE person over several channels; add `feed` + `externalUserId` for a single in-app feed entry.
4. Feed-only: `feed` (with `title`) + `externalUserId` and no channel: an in-app notification only.
In modes 1-2 give exactly one of `templateId` (a published template, plus `params`) or inline `content`; in mode 3 that choice is made per delivery. Get channel ids and each recipient shape from list_channels first. Pass `idempotencyKey` whenever a retry must not deliver twice.
```

### `test_send_template`

- The name "test_send_template" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.recipient): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a real test of a template's PUBLISHED version to one recipient (POST /templates/{id}/test-send; write scope). It goes through the provider for real, so use a recipient the user controls. Test sends don't count toward the monthly quota (a small daily allowance applies instead) and never appear in feeds. Returns `{ sendId }` for get_send_status.
```

## Changes things (5)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_template`

- The name "create_template" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a template (POST /templates; write scope). `channelKind` is permanent and must match the channels you'll send through (list_channels `templateKind`). It is saved as an unpublished draft unless `publish: true`; sending by templateId needs a published version (publish_template). Names are unique per workspace including archived templates: a collision returns 409, so unarchive_template the old one instead. Returns `{ id, requiredParams }`. Designed (drag-and-drop) email templates can only be made in the dashboard.
```

### `create_webhook`

- The name "create_webhook" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create an outbound webhook that Ray POSTs signed event payloads to (POST /tenant-webhooks; write scope; Pro plan or higher, otherwise 403). The URL must be public HTTPS. The response contains the signing `secret` exactly once: show it to the user to store (e.g. as an env var), since it can't be read again, only rotated with update_webhook. Read the `webhooks` docs page for the signature scheme.
```

### `unarchive_template`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Restore an archived template (POST /templates/{id}/unarchive; write scope). This is how to reclaim a name held by an archived template instead of creating a new one.
```

### `update_template_draft`

- The name "update_template_draft" says "update": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Replace a template's draft (PATCH /templates/{id}; write scope). This is a full replacement, not a partial patch: pass content, logTitle, logDescription and paramOverrides as they should end up (get_template first). `name`, `folder` and `channelKind` are required for validation but not changed (channelKind must equal the original). Live sends keep using the published version until you publish, either with `publish: true` here or publish_template. Fails on archived templates.
```

### `update_webhook`

- The name "update_webhook" says "update": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Change a webhook (PATCH /tenant-webhooks/{id}; write scope). Only the fields you pass change; pass at least one. `rotateSecret: true` issues a new signing secret, returned once in the response, and the old secret stops verifying immediately, so the receiving service must be updated at the same time.
```

## Only reads (11)

Looks things up and changes nothing. Claude Code: allow.

### `get_click_stats`

- The name "get_click_stats" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Email link click counts grouped by destination URL (GET /clicks) for a `sendId`, a `campaignId`, or both (at least one is required). Only links from email sends made with `trackClicks: true` are counted.
```

### `get_send_status`

- The name "get_send_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Delivery status of a send (GET /sends/{id}): `aggregate` counts per status over the whole send (pending, claimed, delivered, failed_retryable, failed_terminal, suppressed) plus one page of per-recipient delivery rows including provider errors. Right after sending, rows are usually `pending`; check again after a few seconds. Feed-only sends have no rows. For more rows, pass the returned `nextCursor` as `cursor`.
```

### `get_template`

- The name "get_template" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one template with its published version and its current draft (GET /templates/{id}): content, logTitle/logDescription, `requiredParams` a send must supply, and paramOverrides. Read this before update_template_draft, which needs the full body.
```

### `get_usage`

- The name "get_usage" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The workspace's plan, subscription status and this calendar month's usage against the monthly quota (GET /billing/subscription). `used`/`remaining` are null on unmetered plans. On a hard-capped plan, sends beyond the quota fail with HTTP 402 quota_exceeded.
```

### `get_webhook`

- The name "get_webhook" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one outbound webhook (GET /tenant-webhooks/{id}) including its delivery health (consecutiveFailures, lastDeliveryAt, lastFailureAt, lastError).
```

### `list_channels`

- The name "list_channels" says "list": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
List the delivery channels configured in this workspace (GET /channels). Call this FIRST before sending: each entry's `id` is the `channelConfigId` for send_notification and test_send_template, `kind` is the channel type (ses_email, smtp_email, fcm_push, slack_webhook, discord_webhook, telegram_bot, twilio_sms, sendsms_mn, generic_webhook), `templateKind` is the template channelKind it accepts, and `recipientSchema` is the exact JSON Schema of the `recipient` it expects. Channels and their provider credentials are set up in the Ray dashboard, not through this API; if the list is empty, ask the user to add one there.
```

### `list_feed_notifications`

- The name "list_feed_notifications" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read one end user's in-app notification feed (GET /notifications): the entries created by sends with `feed` or `showInFeed`. This is what an in-app inbox would show, not delivery status (use get_send_status for that). Paginate by passing `nextCursor` back as `cursor`.
```

### `list_templates`

- The name "list_templates" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List message templates (GET /templates): id, name, folder, channelKind, and `publishedVersionId` (null = never published, so it cannot be sent by templateId yet). Archived templates are hidden unless `includeArchived` is true. Use get_template for content and required params.
```

### `list_webhooks`

- The name "list_webhooks" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the workspace's outbound event webhooks (GET /tenant-webhooks): url, subscribed events, enabled flag and delivery health (consecutiveFailures, lastError). Signing secrets are never returned.
```

### `read_docs`

- The name "read_docs" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read Ray's documentation as markdown. With no `slug` it returns the index (llms.txt) listing every page; then pass a page slug, i.e. the path after /docs/ without `.md`, such as `sending`, `templates`, `idempotency`, `errors`, `rate-limits`, `webhooks`, `status-and-feeds` or `channels/telegram`. Use it for anything the tool descriptions don't cover.
```

### `whoami`

- The name "whoami" says "whoami": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Identify the API key this connection uses (GET /me): `tenantId` (the workspace), `apiKeyId` and `scopes`. Write tools need the `write` scope; call this to check before attempting them.
```
