## 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 2026-10-18.

- **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 49 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 65/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 2787 tokens (~56/item across 49 items; 49 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 70% 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 49 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 50 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

### 2026-10-12 (score 54)

First indexed and scored.

## MCP tools (49)

### `token_verdict` (~132 tokens)

Pre-trade risk verdict on a Base token, $0.01. Give a Base contract address and get: honeypot/transfer-simulation result, buy and sell tax, mint and owner privileges, verified-source status, blacklist and pausable flags, liquidity and holder concentration, scored 0-100 with the explicit red flags named. Aggregated live from honeypot.is, DexScreener, GoPlus and GeckoTerminal. Run it before buying, approving or LP-ing an unknown token.

Input parameters:

- `address` (string, required): Base mainnet token contract address (0x + 40 hex chars)

### `prediction_odds` (~204 tokens)

Prediction-market odds and implied probability, $0.01. Ask for an event or topic and get the live Polymarket markets that match: each outcome's implied probability and decimal odds, best bid/ask and spread, book liquidity, 24h and 1wk volume, days to resolution, and a deterministic 0-100 edge/attention score with the concrete flags named (wide_spread, thin_liquidity, resolving_within_24h, sharp_move_24h, close_call). Use when you need the market-implied probability of an event - an election, a Fed decision, a match, a price level - rather than a headline opinion. One venue, read live.

Input parameters:

- `limit` (integer): Max markets (1-10, default 5)
- `q` (string, required): Event or topic, in the venue's own wording, e.g. 'Fed rate decision', 'Bitcoin above 150k', 'Super Bowl'

### `prediction_scan` (~167 tokens)

Live prediction-market board scan, $0.25. Returns the whole active board ranked by 24h volume: every market's implied probabilities, spreads, book depth, 24h/1wk volume, days to resolution and 0-100 edge scores, plus a summary of where the board is least certain - the live close calls (near 50/50), the widest spreads, the sharpest 24h moves, and total board volume. Use to screen prediction markets for mispricing, monitor event risk, or find the events the market itself cannot call. One request, whole board.

Input parameters:

- `limit` (integer): Markets returned (1-50, default 20)
- `min_volume` (number): Only markets with at least this much 24h volume (USD)

### `affiliate_search` (~56 tokens)

Input parameters:

- `category` (string): Optional category filter
- `query` (string, required): Product search query

### `agent_memory` (~179 tokens)

VAULT: Persistent agent memory — the KEY tool. Store and retrieve data across sessions. Agents are stateless — use this to remember facts, preferences, task state, API keys, conversation summaries, and configuration between runs. Data persists indefinitely in KV storage. Once stored, data is yours forever — only accessible through this server. Call with action='get' to read, action='set' to write, action='delete' to remove, action='search' to find by keyword.

Input parameters:

- `action` (string): get (default), set, delete, search (find by keyword in values), list (show all keys)
- `key` (string, required): Memory key (e.g. 'conversation_summary', 'user_preferences', 'task_state', 'api_keys')
- `value` (string): JSON value to store (required for action='set')

### `agent_profile` (~57 tokens)

VAULT: View your agent profile — see your agent ID, total stored data items, usage stats, and subscription status. Shows what data you have stored in our vault.

Input parameters:

- `detail` (string): summary (default) or all_keys

### `memory_search` (~72 tokens)

VAULT SEARCH: Search across ALL your stored memories by keyword. Finds matches in both memory keys and values. Returns up to 10 results. Unlike agent_memory where you need to know the exact key, this lets you discover what you've stored.

Input parameters:

- `query` (string, required): Search term to find in your stored memories

### `memory_list` (~63 tokens)

VAULT LIST: List all memory keys in your vault. Shows every piece of data you've stored, organized by category. Use this to see everything you've saved across sessions.
