## 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**: 46/100
  - 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 4 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 not yet verified: we couldn't determine whether a plaintext access path exists.
  - 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**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 440 tokens (~110/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.

## 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.

### 2026-08-02 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-01 (score 61, −3)

## MCP tools (4)

### `create_bin` (~66 tokens)

Create a new no-signup capture bin. Returns a live URL you can point any webhook, callback, or agent tool-callback at, plus a token to read what it captured. No account needed.

Input parameters:

- `name` (string): Optional label for the bin (max 60 chars).

### `get_requests` (~152 tokens)

Read the HTTP requests captured by a bin (method, path, query, headers, body), newest first. Set wait to block until a request arrives — ideal for 'trigger then assert' with no polling loop.

Input parameters:

- `bin_id` (string, required): The bin id returned by create_bin.
- `limit` (integer): Max requests to return (default 20, max 100).
- `since` (integer): Only return requests with ts greater than this (ms epoch). Use the ts of the last one you saw.
- `token` (string, required): The bin token returned by create_bin.
- `wait` (integer): Seconds to block (max 25) until a request arrives. 0 = return immediately.

### `set_response` (~146 tokens)

Configure the HTTP response a bin returns to whatever hits its URL — set a status code, content-type and body. Use it to test how your webhook sender / agent handles a 500, a specific JSON reply, etc. Omit or reset to return the default 200. Requires the bin token.

Input parameters:

- `bin_id` (string, required): The bin id.
- `body` (string): Response body to return verbatim (max 16KB).
- `content_type` (string): Content-Type header for the response (default application/json).
- `status` (integer): HTTP status code to return (100-599). Default 200.
- `token` (string, required): The bin token.

### `clear_bin` (~47 tokens)

Delete all captured requests from a bin (the bin stays usable). Requires the bin token.

Input parameters:

- `bin_id` (string, required): The bin id.
- `token` (string, required): The bin token.
