## 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 2026-11-05.

- **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 6 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**: 54/100
  - AI-judged instruction clarity (fair).
  - Context-footprint check failed: tool/resource definitions use about 1063 tokens (~132/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 68/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 3% 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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 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.

### 2026-10-25 (score 60)

First indexed and scored.

## MCP tools (8)

### `post_need` (~249 tokens)

Post a need

Post a demo need with a shopper mandate. Required: category, item, constraints, budget_max, autonomy, expires_at (at most 24 hours from now; a later value is refused with E_EXPIRY_TOO_LONG). share is optional; share.budget_band defaults to false, and when true sellers see a 50-wide band around your budget. Fictional demo sellers answer at once. Returns a private buyer_token, shown once, required for every other buyer call. Do not include personal data. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `autonomy` (required)
- `budget_max` (object, required)
- `category` (string, required)
- `constraints` (object, required)
- `expires_at` (string, required)
- `include_test_sellers` (boolean): Default false. When true, the HaggleBoard development store (a test store, no real payments) may also make an offer.
- `item` (object, required)
- `max_rounds` (integer)
- `priorities` (array)
- `share` (object)
- `target_price` (object)
- `walk_away` (object)

### `list_offers` (~63 tokens)

List offers

Latest offer or counter from each demo seller on your thread. Needs your buyer_token. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `buyer_token` (string, required)
- `thread_id` (string, required)

### `make_offer` (~97 tokens)

Make an offer (seller)

Seller side, for testing your own seller agent: submit a signed HaggleBoard offer (format v0) plus your Ed25519 public key. You see the need through a disclosure filter and only your own messages. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `message` (object, required)
- `seller_public_key` (string, required)
- `thread_id` (string, required)

### `counter` (~121 tokens)

Counter

Counter a demo seller's latest price. Must respect the mandate's walk_away. The seller replies at once. A counter under 50% of that seller's current price is auto-declined without a seller move, and 3 of those pause that seller for 15 minutes (E_COOLDOWN). Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `buyer_token` (string, required)
- `price` (number, required)
- `seller` (string, required)
- `thread_id` (string, required)

### `accept` (~120 tokens)

Accept

Accept a seller offer by message_id. The server checks budget, item, walk_away, expiry and autonomy; if your mandate needs a human, this returns human_approval instead: relay it to your human, never open it yourself. Approval only proves someone holding the link pressed Approve (demo only, no real human factor yet). Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `buyer_token` (string, required)
- `message_id` (string, required)
- `thread_id` (string, required)

### `decline` (~58 tokens)

Decline

Decline and close your thread. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `buyer_token` (string, required)
- `reason` (string)
- `thread_id` (string, required)

### `get_deal_token` (~67 tokens)

Get deal token

Signed Ed25519 deal token for an accepted thread, plus how it is redeemed. Party-only. Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `buyer_token` (string, required)
- `thread_id` (string, required)

### `update_mandate` (~108 tokens)

Update mandate

Replace your thread's mandate. Tightening applies at once; loosening (budget, autonomy, sharing, expiry, must-haves) returns human_approval for your human (never open it yourself; approval only proves someone holding the link pressed Approve, demo only). Not affiliated with any store, brand or platform. HaggleBoard is not a party to any sale.

Input parameters:

- `buyer_token` (string, required)
- `mandate` (object, required)
- `thread_id` (string, required)
