First indexed and scored.

## MCP tools (20)

### `authenticate` (~59 tokens)

Connect to Site Spy with an API key. If the user doesn't have one, ask them to open https://sitespy.app/dashboard to log in and copy their key from the Settings > API tab.

Input parameters:

- `api_key` (string, required): Site Spy API key

### `auth_status` (~20 tokens)

Check whether the MCP server is currently authenticated with Site Spy.

### `list_watches` (~47 tokens)

List all monitored websites. Returns each watch with its UUID, URL, title, status, last checked/changed timestamps, and tags.

Input parameters:

- `tag` (string): Filter by tag UUID

### `create_watch` (~119 tokens)

Start monitoring a URL for changes. Returns the UUID of the new watch.

Input parameters:

- `check_hours` (number): Hours between checks (default: uses account setting)
- `check_minutes` (number): Minutes between checks
- `fetch_backend` (string): How to fetch the page: html_requests (fast, no JS) or html_webdriver (browser with JS)
- `tag` (string): Tag UUID to categorize this watch
- `title` (string): Human-readable name for this monitor
- `url` (string, required): URL to monitor for changes

### `get_watch` (~37 tokens)

Get full details of a specific watch including its configuration, last check status, and change history summary.

Input parameters:

- `uuid` (string, required): Watch UUID

### `update_watch` (~119 tokens)

Update a watch's configuration. Use this to pause/resume, change check interval, update title, or modify notification settings.

Input parameters:

- `check_hours` (number): Hours between checks
- `check_minutes` (number): Minutes between checks
- `notification_muted` (boolean): Mute or unmute notifications
- `paused` (boolean): Pause or resume monitoring
- `tag` (string): Tag UUID
- `title` (string): New title
- `url` (string): New URL to monitor
- `uuid` (string, required): Watch UUID

### `delete_watch` (~32 tokens)

Stop monitoring a URL and delete the watch with all its history.

Input parameters:

- `uuid` (string, required): Watch UUID to delete

### `get_change_history` (~41 tokens)

Get the list of timestamps when changes were detected for a watch. Use these timestamps with get_snapshot or get_diff.

Input parameters:

- `uuid` (string, required): Watch UUID

### `get_snapshot` (~48 tokens)

Get the page content captured at a specific timestamp. Use get_change_history first to find valid timestamps.

Input parameters:

- `timestamp` (string, required): Timestamp from change history
- `uuid` (string, required): Watch UUID

### `get_diff` (~58 tokens)

Compare page content between two timestamps to see exactly what changed. Use get_change_history to find valid timestamps.

Input parameters:

- `from_timestamp` (string, required): Earlier timestamp
- `to_timestamp` (string, required): Later timestamp
- `uuid` (string, required): Watch UUID

### `search_watches` (~40 tokens)

Search across all watches by URL, title, or content. Returns matching watches.

Input parameters:

- `query` (string, required): Search query (matches against URL, title)

### `list_tags` (~17 tokens)

List all available tags/categories for organizing watches.

### `trigger_recheck` (~54 tokens)

Force an immediate recheck of all watches (or filtered by tag). Useful when you need fresh data now rather than waiting for the next scheduled check.

Input parameters:

- `tag` (string): Only recheck watches with this tag UUID

### `fetch_url` (~429 tokens)

Fetch a single known URL through Site Spy. Do NOT use this for discovery — use web_search to find URLs first, then fetch_url on each result. Do NOT fetch google.com / bing.com directly (they always block — wastes the cascade budget). For known static sites prefer fetch_backend: 'html_requests' (≤10s). For SPAs use 'html_webdriver'. For Cloudflare-protected pages use 'flaresolverr'. 'auto' cascades through all three and is capped at 30s total (FETCH_URL_AUTO_TOTAL_TIMEOUT_SECONDS). On failure, response includes attempts[] and cascade_summary so you can see what was tried. This does not create a watch or save history.

Input parameters:

- `body` (string): Optional request body string.
- `fetch_backend` (string): Fetch strategy. Default 'auto' cascades html_requests -> html_webdriver -> flaresolverr with a 30s total cap. Prefer 'html_requests' explicitly for fast static sites.
- `headers` (object): Optional request headers.
- `ignore_status_codes` (boolean): Return content for non-2xx responses instead of failing. Defaults to true.
- `include_filters` (array): Optional selectors used by auto mode to decide if browser rendering is needed.
- `js` (string): JavaScript to execute before extraction when a browser backend is used.
- `max_content_chars` (integer): Maximum returned characters for content fields.
- `method` (string): HTTP method. Browser fetchers use GET-like navigation.
- `output` (string): Response content format. Defaults to text.
- `screenshot` (boolean): Return a base64 screenshot when the browser backend captures one.
- `screenshot_format` (string): Screenshot format. Defaults to PNG.
- `timeout` (integer): Per-backend timeout in seconds (1-120). 'auto' mode also has a separate 30s total wall-clock cap (env FETCH_URL_AUTO_TOTAL_TIMEOUT_SECONDS) that bounds the whole cascade.
- `url` (string, required): URL to fetch
- `wait_seconds` (integer): Extra browser wait before extracting content.

### `web_search` (~183 tokens)

Search the web via DuckDuckGo HTML and return a list of result URLs with titles and snippets. Use this BEFORE fetch_url when the user asks you to 'search', 'find', 'look up', or otherwise discover content — instead of guessing google.com (which always blocks). Pipeline: web_search(query) -> pick relevant results -> fetch_url(result.url, fetch_backend: 'html_requests') on each. Returns up to 20 results.

Input parameters:

- `debug` (boolean): When true, include a debug_html_excerpt in the response for troubleshooting parsing failures.
- `limit` (integer): Max results to return. Default 10, max 20.
- `query` (string, required): Search query.
- `region` (string): DuckDuckGo region code. Default 'wt-wt' (worldwide). Examples: 'us-en', 'fr-fr', 'de-de'.

### `get_ai_summary` (~56 tokens)

Get the AI-generated plain-English summary of a watch's most recent change. Requires a Pro or Business plan. Returns the summary text if available, or a message if no summary exists yet.

Input parameters:

- `uuid` (string, required): Watch UUID

### `get_rss_settings` (~26 tokens)

Get the current RSS feed settings including whether feeds are enabled and the feed token.

### `generate_rss_token` (~83 tokens)

Generate or regenerate an RSS feed token. Use the token to build feed URLs: {server}/rss?token={token} for all watches, {server}/rss/watch/{uuid}?token={token} for a single watch, {server}/rss/tag/{tag_uuid}?token={token} for a tag. Regenerating invalidates all existing feed URLs.

### `revoke_rss_token` (~24 tokens)

Revoke the RSS feed token, disabling all RSS feed access immediately.

### `get_notifications` (~23 tokens)

Get the current notification settings (email, Telegram, web push, etc.).
