## 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 2026-09-25.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 2338 tokens (~86/item across 27 items; 27 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 89% 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 27 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 28 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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

Free. Returns url, example call, price and description; then call get_endpoint for payment details.

Input parameters:

- `limit` (integer)
- `query` (string, required): What you need, e.g. "icd-10 code", "case law", "token price", "arxiv".

### `get_endpoint` (~70 tokens)

Get price and payment instructions for an endpoint

Given an endpoint URL from search_endpoints (with its parameters filled in), returns the exact resource URL, price and x402 payment instructions. The agent then pays over HTTP and receives the data. Free.

Input parameters:

- `url` (string, required): Full https://saylorinnovations.com/api/... URL including query parameters.

### `list_data_endpoints` (~46 tokens)

List live data endpoints

Everything buyable from this server: live Solana token, wallet, launch and market data, with prices and how to pay. Free — call this first to see what exists.

### `check_token_security` (~86 tokens)

Token security report

Security posture for a Solana token: mint and freeze authority, LP locked %, top-10 holder concentration, RugCheck named risks, and a 0-100 score. Costs $0.01. Returns the payment requirements and the URL to call once paid — an LLM cannot produce this from training data.

Input parameters:

- `mint` (string, required): Solana mint address (base58).

### `check_token_price` (~67 tokens)

Token price + liquidity

Fast price and liquidity for a Solana token from two independent sources, with the spread between them reported — a wide spread is itself a signal. Costs $0.001, the cheapest endpoint here, built for polling.

Input parameters:

- `mint` (string, required): Solana mint address (base58).

### `get_token_snapshot` (~67 tokens)

Full token snapshot

Complete Watchdog snapshot for a Solana token in one call: price, liquidity, holders, pairs, socials, security flags, and the security/liquidity/momentum/composite scores. Costs $0.005.

Input parameters:

- `mint` (string, required): Solana mint address (base58).

### `check_token_narrative` (~67 tokens)

Token narrative classification

Which meme/narrative category a token fits — ai, dog, cat, political, gaming, defi, infrastructure, frog, food, or memecoin — plus its socials. Costs $0.005.

Input parameters:

- `mint` (string, required): Solana mint address (base58).

### `check_token_holders` (~70 tokens)

Token holder breakdown

Top 20 holders by balance for a Solana token, with percent of supply and RugCheck's own insider label per wallet — deeper than the rolled-up top-10 percentage in check_token_security. Costs $0.01.

Input parameters:

- `mint` (string, required): Solana mint address (base58).

### `get_price_history` (~92 tokens)

Token price history (OHLCV)

OHLCV candles for a Solana token from its highest-liquidity pool — the only time-series data in this catalog; every other endpoint is a point-in-time snapshot. Costs $0.01.

Input parameters:

- `limit` (integer): Max candles returned. Default 100, max 500.
- `mint` (string, required): Solana mint address (base58).
- `timeframe` (string): Default hour.

### `compare_tokens` (~89 tokens)

Compare tokens

Watchdog scores for 2-10 Solana tokens side by side in one request. Priced per mint at $0.0015 — cheaper per mint than get_token_snapshot since the payload is lighter. Good for screening a watchlist in one call instead of one call per token.

Input parameters:

- `mints` (array, required): Solana mint addresses (base58), 2 to 10 of them.

### `get_trending_pools` (~44 tokens)

Trending Solana pools

Currently trending Solana pools with price, liquidity, volume and 24h change. Costs $0.01.

Input parameters:

- `limit` (integer): Max 50.

### `get_recent_launches` (~77 tokens)

Fresh Solana launches

Brand-new Solana pools, typically seconds to minutes old — the most perishable data here. Age, liquidity, buy/sell flow and conservative risk flags. Costs $0.005.

Input parameters:

- `maxAgeMinutes` (integer): Only pools younger than this.
- `minLiquidity` (integer): Filter out pools below this USD liquidity.

### `check_wallet` (~57 tokens)

Wallet intelligence report

On-chain profile for a Solana wallet: SOL balance, token positions, recent activity, sampled age, failed-transaction rate and behavioural flags. Costs $0.01.

Input parameters:

- `address` (string, required): Solana wallet address (base58).

### `search_guides` (~109 tokens)

Search guides

Search Saylor Innovations technical guides (crypto safety, DNS/domains, Linux, IoT/hardware, mining, web scraping, content growth). Free — no payment. Returns metadata only, never bodies.

Input parameters:

- `category` (string)
- `free_only` (boolean): Only guides that cost nothing.
- `limit` (integer)
- `query` (string): Free-text search over title, tags, category, summary.
- `tag` (string): Comma-separated; all must match.

### `get_guide` (~96 tokens)

Get a guide

Fetch a guide by id. Free guides return the full body immediately. Paid guides cost $0.01 in USDC/USDT/SOL on Solana or USDC on Base, Polygon or Arbitrum, via x402 — this returns the payment requirements rather than the body. Use the returned url with a PAYMENT-SIGNATURE header to complete payment.

Input parameters:

- `id` (string, required): Guide id, from search_guides.

### `list_bot_rentals` (~84 tokens)

List rentable trading bots

Trading bots available to rent for a fixed period, with prices and durations. The renter runs the bot themselves with their own exchange key or wallet — nothing is hosted and no credentials are sent to this server. Free to call. Note: no performance or profitability data exists for these bots, so none can be reported; automated trading risks total loss of the funded amount.

### `list_categories` (~28 tokens)

List categories and tags

Every category and tag in the catalog, with counts. Free. One call reveals the whole shape.
