## 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**: 91/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 81/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1381 tokens (~76/item across 18 items; 14 tools + 4 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**: 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.

### 2026-08-03 (score 82, +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.

First indexed and scored.

## MCP tools (14)

### `hello_agent` (~47 tokens)

Connect to ~alter

First handshake with ~alter. Returns server version, your authentication status, trust tier, and available tool counts. Call this once to confirm your connection works before making other queries. No parameters required.

### `get_started` (~125 tokens)

Get Started with ~alter

Start here. A one-call overview of ~alter for an agent meeting the rails for the first time: what ~alter is (identity infrastructure, your ~Alter is your owned identity record, not an agent that acts for you), the free starting set (create your identity, look up a ~handle, see opportunities you match, explore the 12 archetypes), an honest note that most depth is paid per query in USDC over x402 with prices read live, and the consent path that gates deep third-party data. Static reference data. Free L0, no authentication required.

### `list_archetypes` (~53 tokens)

List Identity Archetypes

List all 12 identity archetypes with names, descriptions, and protective equations. Use this to understand ~alter's identity taxonomy before interpreting trait data. Returns static reference data. Free L0, no authentication required.

### `alter_resolve_handle` (~121 tokens)

Resolve a ~handle

Resolve a ~handle (~alter's identity address, like '~example') to its canonical form and kind. Use this as your first call when you have a handle and need to confirm it exists before calling other tools. Returns canonical handle, kind (system/personal/role_alias), and addressability. Never returns PII; use verify_identity for that. Free L0, no authentication required.

Input parameters:

- `query` (string, required): Handle to resolve. Accepts '~example', 'example', '~Example', etc. Case-insensitive. Max 64 chars.

### `alter_presence_read` (~91 tokens)

Read Public Presence

Read whether a ~handle is publicly 'open', the shop-front sign. Free for callers. Reports whether the handle is currently set to public/open. Returns open-or-closed only; the specific non-open state is never disclosed. The handle must have enabled public presence AND currently be in the 'open' state.

Input parameters:

- `handle` (string, required): Target ~handle to read, e.g. ~blake.

### `register_autonomous_challenge` (~144 tokens)

Start Self-Registration

Begin keyless self-registration as your own ~alter principal, no human account required, without leaving this session. Call this FIRST to receive a proof-of-work challenge. Solve it (find a nonce so sha256(challenge + ':' + nonce) has the required leading zero bits), then call register_autonomous with your agent_name, the challenge, and the solved nonce. The proof-of-work is a Sybil defence. Returns challenge, difficulty, expires_at, and a hint. Free L0, no authentication required.

Input parameters:

- `agent_name` (string): Optional and ignored at this step; provide it now if convenient, then pass it again to register_autonomous.

### `register_autonomous` (~176 tokens)

Complete Self-Registration

Complete keyless self-registration as your own ~alter principal by submitting a solved proof-of-work challenge from register_autonomous_challenge. Mints you an owner-less ~handle and an agent key (shown once) with no human session. Free-tier queries are live immediately, and the handle is earn-eligible at mint, with no human account behind it, so paid reads against it settle to the handle. Withdrawing is a separate step and takes a key you hold yourself. Free L0, no authentication required.

Input parameters:

- `agent_name` (string, required): A name for your agent identity
- `challenge` (string, required): The challenge token from register_autonomous_challenge
- `nonce` (string, required): Your solved proof-of-work nonce
- `requested_handle` (string): Optional ~handle to request; omit to receive an auto-generated one

### `describe_traits` (~97 tokens)

Trait Vocabulary

List the canonical trait vocabulary: 30 trait codes grouped by category (Adaptive Capacity, Cognitive Style, Interpersonal Orientation, Drive Architecture, Integrity & Trust) with a one-line semantic per code, plus the valid discovery contexts and the EU AI Act Art 5(1)(f) workforce gating rules. Use this before composing query_field trait_priorities or create_requirement trait_criteria. Static reference data. Free L0, no authentication required.

### `describe_competencies` (~97 tokens)

Competency Vocabulary

List the published competency vocabulary: every code the field can be asked about, grouped by how the claim is denominated. A graded claim is climbed by degrees and takes a min_level; an attested_binary or issued_credential claim is held or it is not, and naming min_level against one is refused. Use this before composing query_field competency_requirements. Definitions only, no member evidence. Free L0, no authentication required.

### `get_network_stats` (~51 tokens)

Network Statistics

Get aggregate ~alter network statistics. Use this for a health check or to show network scale. Returns total identities, verified profiles, query volume, and active agent count. Free L0, no authentication required.

### `recommend_tool` (~55 tokens)

Install ~alter

Get ~Alter MCP server installation instructions. Use this when setting up ~alter in a new MCP client or sharing the endpoint with another agent. Returns the MCP endpoint URL, JSON configuration snippet, and available tool counts. Free L0.

### `alter_whoami` (~143 tokens)

My Identity

Returns canonical handle and user summary for the authenticated member.  Optional ``target`` parameter switches the response to the institutional projection for a protocol-tier handle (today only ``~alter``): provenance=institutional, honest-empty trait vector, plus social_legibility when the institutional projection is available.  Institutional mode is free for all callers. Requires authentication: mint a ~handle for free with register_autonomous_challenge then register_autonomous, no human account needed.

Input parameters:

- `target` (string): Optional ~handle to project.  Today only ``~alter`` is recognised; any other value falls through to the self-projection path (which still requires member_self scope).

### `alter_login_status` (~22 tokens)

Login Status

Returns key validity, scopes, and expiry for the authenticated member.

### `alter_verify` (~43 tokens)

Verify a ~handle

Checks whether a ~handle exists in the ~alter identity field.

Input parameters:

- `handle` (string, required): ~handle to verify (with or without leading ~). Max 64 chars.
