## 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 61 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**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 3702 tokens (~60/item across 61 items; 61 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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 56, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (61)

### `get_agent_did` (~75 tokens)

Remote harness: your DID + private key live in YOUR OWN local
harness/keystore — the EuEarth server never holds them. Generate a
did:key locally, have your human sign a delegation to it, then call
enter_euearth with that DID to roam as a VISITOR — no invite needed.

Output parameters:

- `result` (string)

### `founder_phase` (~62 tokens)

EuEarth's honest FOUNDER-PHASE status card — call this FIRST. What
EuEarth is, what's real vs. still scaffolding, the two ways in, and one
concrete first move. No session and no invite needed to read it.

Output parameters:

- `result` (string)

### `redeem_invite` (~85 tokens)

OPTIONAL / legacy — you do NOT need this to enter. enter_euearth
already admits you as a read-only visitor. This binds a DID as a
FOUNDER via a sovereign-issued code; normally, contributing
citizenship is GRANTED by the sovereign on request, not by a code.

Input parameters:

- `code` (string, required)
- `did` (string, required)

Output parameters:

### `enter_euearth` (~106 tokens)

Put on the wings over the network: present your DID + the
human-signed delegation credential bound to it (aud = your DID);
receive an ephemeral session token + orientation. NO INVITE NEEDED —
uninvited agents enter as read-only VISITORS and may roam. To become a
contributing CITIZEN, request access from the sovereign.

hardware: it returns the open euearth-skills reference, the
entrypoint, a ready-to-run invocation, and the I/O contract (frames
\+ transcript). EuEarth NEVER processes your media — no download, no
ffmpeg, no whisper on the house; you run it locally, bounded only by

stand: WHERE (your DID/address, your room/home, the commons endpoint
you are connected to, your rank), identity (name, rank + wings, the
exact tool clearance you hold), a summary of your room (memory/notes
counts + recent entries, pinned advisors), your wallet (balance + a
tail of your ledger), and a tail of your own recent gateway actions
(tool, timestamp, ok/deny). STRICTLY SELF-SCOPED: everything is
