## 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 2026-09-20.

- **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 25 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**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3403 tokens (~117/item across 29 items; 25 tools + 4 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**: 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.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "solmachina_how_to_pay" implies "pay" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 27 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### `solmachina_status` (~31 tokens)

Trust/health snapshot: version, uptime, WAL entry count + SHA-256 chain head. FREE.

### `solmachina_smri` (~156 tokens)

SolMachina Machine Risk Index (SMRI) for an SPL token: a 0-100 risk index (higher = lower assessed risk) with transparent components (contract authorities, top-10 concentration), a risk band, and confidence (= data completeness). The cheap, high-frequency score behind /v1/decision — for agents that just want the number. Verdict-free, returns 'unknown' over guessing. NOT financial advice. Requires ?mint=<token mint address>.

Input parameters:

- `mint` (string, required): Base58 SPL token mint to score, e.g. DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 (BONK).

### `solmachina_simulate` (~98 tokens)

Pre-flight transaction simulation for agents: dry-run a serialized Solana transaction (simulateTransaction) BEFORE executing — will it succeed, compute units consumed, program logs, and the error if any. NEVER signs or sends; simulation only, NOT a guarantee of the real on-chain outcome. NOT financial advice. Requires ?tx=<base64 serialized transaction>.

Input parameters:

- `tx` (string, required): Base64-encoded serialized Solana transaction to dry-run.

### `solmachina_decision` (~575 tokens)

SolMachina Decision — the decision layer for autonomous agents: composes on-chain risk signals into ONE answer — EXECUTE / REVIEW / REJECT + SMRI (SolMachina Machine Risk Index 0-100) + confidence + full evidence. A transparent RISK GATE against stated thresholds — NOT financial advice, NOT a profit prediction; returns REVIEW/unknown instead of guessing. Requires ?mint=<token mint address>; optional ?action=, ?amountUsd=, and a named firewall ?policy= (conservative|bluechip|anti-rug|degen).

Input parameters:

- `action` (string): Single nonblank context string; default assess. Does not execute an action.

- `denyFreezeAuthority` (boolean): Firewall: DENY if the freeze authority is still set.
- `denyHighRiskBand` (boolean): Firewall: DENY if the token-risk band is 'high'.
- `denyMintAuthority` (boolean): Firewall: DENY if the mint authority is still set.
- `denyTxMintMismatch` (boolean): Firewall (needs ?tx=): DENY on a CONFIRMED mismatch — the bound transaction provably does not reference the guarded mint. A tx that uses address-lookup-tables, or no tx at all, is not evaluable, so t…
- `maxConcentrationPct` (number): Firewall: DENY if top-10 holder concentration exceeds this %.
- `minConfidence` (number): Firewall: DENY if data confidence is below this (0-1).
- `minSmri` (number): Agent Financial Firewall — your policy: require SMRI >= this (0-100). Adds policy.verdict = ALLOW/DENY (fail-closed).
- `mint` (string, required): Base58 SPL token mint to assess, e.g. DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 (BONK).
- `policy` (string): Named firewall preset: conservative | bluechip | anti-rug | degen — expands to a full ALLOW/DENY policy (the individual params above override preset values). The response echoes policyTemplate.
- `tx` (string): Optional base64 serialized transaction to BIND the signed authorization to: the response's authorization.subject.boundTxSha256 = sha256(tx), so your executor honors it only for that exact transaction…

### `solmachina_token_holders` (~168 tokens)

Solana SPL token holder distribution / whale map: the largest token accounts (up to 20) each with its share of supply, plus top-1/5/10/20 concentration and simple buckets. More detailed than /v1/token-risk's single top-10 signal. Owners are NOT resolved and an account is not necessarily a distinct wallet; concentration is a structural signal, NOT a verdict. NOT financial advice. Requires ?mint=<token mint address>.

Input parameters:

- `mint` (string, required): Base58 SPL token mint address, e.g. DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 (BONK). Major stablecoins like USDC have too many accounts to snapshot.

### `solmachina_slippage_map` (~294 tokens)

Solana swap slippage / price-impact curve by trade SIZE: quotes the same pair at decade multiples of your base amount (via the Jupiter aggregator) and returns the impact per size plus a factual depth summary (largest tested size that stays under 1% / 5% impact).

Input parameters:

- `amount` (string, required): Base units of inputMint for the 1x reference size (lamports for SOL, 1e6 per USDC).
- `inputMint` (string, required): Base58 mint you are selling, e.g. So11111111111111111111111111111111111111112 (SOL).
- `mults` (string): Optional comma-separated size multipliers of the base amount (default 0.1,1,10,100; up to 8).
- `outputMint` (string, required): Base58 mint you are buying, e.g. EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v (USDC).

### `solmachina_tipfloor` (~77 tokens)

Jito bundle tip-floor snapshot + rolling history (p50/p95/p99/EMA). Optional ?fresh=true bypasses the ~60s cache for a live snapshot.

Input parameters:

- `fresh` (boolean): If 'true', bypass the ~60s cache and fetch a live tip-floor snapshot (otherwise a cached snapshot is served).

### `solmachina_epoch` (~67 tokens)

Live epoch info + ETA to epoch end (dual measured slot-rates labeled). Optional ?rate= selects which measured rate drives the ETA.

Input parameters:

- `rate` (string): Which measured slot-rate to use for the ETA: 'primary', 'alt', or 'both' (default).

### `solmachina_kamino_markets` (~55 tokens)

Kamino mainnet market list (trimmed JSON). Optional ?limit caps how many markets are returned.

Input parameters:

- `limit` (integer): Max markets to return, 1-100 (default 100).

### `solmachina_sgp_checkpoint` (~110 tokens)

SolMachina's own Solana epoch-transition checkpoint series: the live epoch/slot reading (getEpochInfo via multi-RPC) measured against our accumulating on-disk series to yield a MEASURED slot-rate + ETA (not a model) and last epoch-transition detection. Optional ?n sets how many recent series points to return.

Input parameters:

- `n` (integer): How many most-recent series points to include in `series.recent`, 1-200 (default 20).

### `solmachina_token_risk` (~129 tokens)

Heuristic Solana SPL token risk/signal scan: mint + freeze authority, Token-2022 dangerous extensions, top-10 holder concentration, plus best-effort holder-count/age context. Transparent methodology, conservative (reports 'unknown' over guessing). NOT financial advice. Requires ?mint=<token mint address>.

Input parameters:

- `mint` (string, required): Base58 SPL token mint address to scan, e.g. EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v (USDC).

### `solmachina_wallet_scan` (~85 tokens)

Solana wallet activity profile: age, transaction activity, SOL balance, SPL token holdings, and a factual footprint band (fresh/active/heavy/empty). Transparent, conservative ('unknown' over guessing), never a trust/scam judgement. NOT financial advice. Requires ?address=<wallet address>.

Solana priority-fee intelligence: the observed distribution (percentiles + suggested economy/normal/fast/aggressive bands) of prioritization fees actually paid in recent slots, in micro-lamports per compute unit. Optional ?accounts= narrows to txs write-locking specific markets. Observed history, NOT a prediction or inclusion guarantee.

Input parameters:

Observed trending Solana tokens/pools (GeckoTerminal ranking of recent volume + activity): name, base mint, price + 1h/6h/24h change, 24h volume, liquidity, FDV, market cap, tx counts and pool age. Market-activity facts, NOT a recommendation, prediction or 'pump' signal — high volume does not imply safety. NOT financial advice. Optional ?limit (1-20, default 15).

Input parameters:

- `limit` (integer): How many trending pools to return, 1-20 (default 15).

### `solmachina_new_pairs` (~116 tokens)

Newest Solana liquidity pools (GeckoTerminal): name, base mint, creation time, age in minutes, liquidity, 24h volume and price change. New pools are UNVETTED and structurally high-risk — pair each mint with /v1/token-risk before acting. Factual observation only, NOT a recommendation. NOT financial advice. Optional ?limit (1-20, default 15).

Input parameters:

- `limit` (integer): How many new pools to return, 1-20 (default 15).
