## 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 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `check_url` (~100 tokens)

Check whether a URL is allowed under a network policy. Returns { allowed, reason } without making any actual request. Use this to gate tool calls before they execute.

Input parameters:

- `method` (string): HTTP method (default GET).
- `policy` (object, required): A simplified network policy. Use { allow: ["api.openai.com", "*.example.com"] }. Optional: deny: string[], methods: string[].
- `url` (string, required): URL to check.

### `check_urls_batch` (~103 tokens)

Batch-check multiple URLs against the same policy. Returns per-URL decisions plus an allowed/denied summary. Useful for vetting a list of pending tool fetches.

Input parameters:

- `method` (string): HTTP method applied to all URLs.
- `policy` (object, required): A simplified network policy. Use { allow: ["api.openai.com", "*.example.com"] }. Optional: deny: string[], methods: string[].
- `urls` (array, required): URLs to check.

### `validate_policy` (~79 tokens)

Sanity-check a policy spec without making any decision. Catches: empty allow list, overly broad "*" wildcards, malformed host patterns containing schemes/paths/queries.

Input parameters:

- `policy` (object, required): A simplified network policy. Use { allow: ["api.openai.com", "*.example.com"] }. Optional: deny: string[], methods: string[].
