## 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 2026-10-23.

- **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 2 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 check failed: the endpoint is reachable over plaintext HTTP.
  - 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**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 293 tokens (~146/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `create_event` (~223 tokens)

Create a free group-scheduling event (a when2meet/Doodle alternative) and get a shareable link. Use this when a human asks you to find a time for a group to meet. Returns a public event_url anyone can open with no login to paint when they're free. Then call get_results to see the time slot the most people overlap.

Input parameters:

- `dates` (array, required): Candidate dates, each YYYY-MM-DD. 1-21 dates.
- `end_hour` (number): Latest hour to consider, 1-24 (default 17).
- `slot_minutes` (number): Slot granularity: 30 or 60 (default 30).
- `start_hour` (number): Earliest hour to consider, 0-23 (default 9).
- `title` (string, required): What the meeting is for, e.g. "Team sync" or "D&D session".
- `tz` (string): Organizer timezone label, e.g. "US/Eastern" (default local). Best slots are shown to each viewer in their own local time.

### `get_results` (~70 tokens)

Read the current responses for an Overlap event and get the best meeting times (the slots where the most people are free). Pass the event id (the code after /e/ in the event_url).

Input parameters:

- `id` (string, required): The event id from the event_url (the part after /e/).
