## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 355 tokens (~118/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 62)

First indexed and scored.

## MCP tools (3)

### `create_watch` (~231 tokens)

Create a standing watch

Create a standing watch. Types: url (page text diff), rss (new feed items), price (crypto threshold/24h-move via CoinGecko id), edgar (new SEC filings by ticker+forms, with decoded 8-K item codes). Returns watch_id, key, and the poll URL.

Input parameters:

- `above` (number): price: alert when USD price crosses above this
- `below` (number): price: alert when USD price crosses below this
- `cik` (number): edgar: SEC CIK, as an alternative to ticker
- `coin` (string): price: CoinGecko id, e.g. 'bitcoin'
- `forms` (array): edgar: form filter, e.g. ["8-K","4"]
- `move_pct_24h` (number): price: alert when |24h change| exceeds this percent
- `ticker` (string): edgar: stock ticker, e.g. 'NVDA'
- `type` (string, required): watch type
- `url` (string): url|rss: page or feed URL to watch

### `poll_alerts` (~84 tokens)

Poll a watch for new alerts

Poll a watch for alerts since a cursor. Pass since={last seq you saw}; the response carries a new cursor. Polling keeps the watch alive.

Input parameters:

- `key` (string, required): key returned by create_watch
- `since` (number): highest alert seq already seen; 0 on first poll
- `watch_id` (string, required): watch_id returned by create_watch

### `delete_watch` (~40 tokens)

Delete a watch

Stop and delete a watch. Free.

Input parameters:

- `key` (string, required): key returned by create_watch
- `watch_id` (string, required): watch_id to delete
