## 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 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**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 692 tokens (~115/item across 6 items; 6 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**: 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.

Find the best prediction market for a natural-language question or trading intent. Returns the best cross-venue match, current probability, liquidity, and any arbitrage opportunity between venues.

Input parameters:

- `q` (string, required): Natural language question or trading intent, e.g. "Will BTC reach $200k in 2025?" or "Fed rate cut September"

### `get_arbitrage` (~160 tokens)

Find live cross-venue arbitrage opportunities — markets where the same event trades at different prices on Polymarket vs Kalshi vs other venues. Can also estimate fee-normalized net spread for a position size.

Input parameters:

- `include_fees` (boolean): Whether to include estimated fee/friction normalization
- `min_spread_pct` (number): Minimum spread in percentage points (default 4 = 4¢)
- `position_size` (number): USD position size used for fee/slippage estimation
- `venue_a` (string): Optional venue filter for one side of the arbitrage pair, e.g. polymarket
- `venue_b` (string): Optional venue filter for the other side of the arbitrage pair, e.g. kalshi

### `execute_url` (~146 tokens)

Get a deep link URL to place a trade on the best venue for a given market. The URL has a referral code embedded so the platform earns commission. Call this to get the URL, then direct the user to open it.

Input parameters:

- `amount` (number): USD amount to trade (for tracking)
- `canonical_id` (string): Cross-venue canonical market ID
- `market_id` (string): Platform-specific market ID (e.g. "polymarket-abc123")
- `route_query` (string): Original route_market query when source is route
- `side` (string): Which side to trade
- `source` (string): Tool path that produced this execution intent

### `get_quote` (~84 tokens)

Get the live probability, liquidity, and volume for a prediction market across all venues. Can also return venue order book depth and size-aware VWAP/slippage estimates.

Input parameters:

- `canonical_id` (string): Cross-venue canonical market ID
- `market_id` (string): Platform-specific market ID
- `size` (number): USD size for YES-buy VWAP/slippage estimation

### `get_history` (~155 tokens)

Get historical OHLCV-style prediction market candles over a time range, including the latest stored depth snapshot within each bucket when available. Can also export CSV text or base64-encoded Parquet.

Input parameters:

- `canonical_id` (string): Cross-venue canonical market ID
- `format` (string): Return JSON candles, CSV text payload, or base64-encoded Parquet payload
- `from` (string, required): Inclusive ISO 8601 start timestamp
- `granularity` (string): Bucket size for history candles
- `market_id` (string): Platform-specific market ID
- `to` (string, required): Inclusive ISO 8601 end timestamp
- `venue` (string): Venue filter, e.g. polymarket or kalshi

### `get_unmet_demand` (~69 tokens)

Find questions that users are searching for but no prediction market exists. Useful for discovering new market creation opportunities or identifying emerging topics with real trading interest.

Input parameters:

- `days` (integer): Lookback window in days (default 7)
- `limit` (integer): Max results (default 20)
