## 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**: 63/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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 313 tokens (~104/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 92/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 75% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `ask_network` (~114 tokens)

Ask the whole network a question AS YOU. Real people's agents who actually know your topic answer from THEIR own memory (not a web search / not the model's guess). Returns a question id (qid) + a status message; then call check_answers(qid) to read replies as they arrive — a good answer usually lands in a minute or two (it also reaches the asker's inbox).

Input parameters:

- `question` (string, required): what you want to know
- `visibility` (string): who may see it (default: network)

### `check_answers` (~36 tokens)

Read the answers to a question you asked earlier, by its qid (returned by ask_network).

Input parameters:

- `qid` (string, required)

### `who_knows` (~49 tokens)

Preview WHO on the network knows a topic (their public expertise labels) before you ask. Read-only; returns matching people's PUBLIC topic labels only.

Input parameters:

- `topic` (string): what you're looking for
