Description
Solana & Base DeFi intelligence for AI agents over x402: decisions, risk, signed receipts.
What our measurements say
io.github.imnotamob/solmachina-x402 is a remote MCP server published at api.solmachina.com. It has been probed 8 times since 9/12/2026. It answered in 8 of them (100.0%), a near-uninterrupted record. Median response time is 263 ms, placing it among the faster endpoints. It exposes a broad tool surface of 25 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names are generally descriptive and indicate their purpose clearly.
- Some tools provide clear usage scenarios in their descriptions.
Weaknesses
- Descriptions for some tools are vague or incomplete (e.g., 'solmachina_simulate' ends abruptly).
- Parameter requirements are inconsistently documented (e.g., 'solmachina_how_to_pay' does not explicitly state 'endpoint' is optional).
- Tool overlap exists (e.g., 'solmachina_token_risk' vs 'solmachina_token_intel').
solmachina_simulate— Description abruptly cuts off with 'NOT financi' without explanation.solmachina_how_to_pay— Parameter 'endpoint' is optional but not explicitly stated in description.solmachina_token_risk— Overlaps with 'solmachina_token_intel' in token risk analysis functionality.

solmachina_catalogDiscover the x402 catalog (endpoints, USDC prices, category, network, payTo). FREE.
solmachina_sampleFREE preview of any endpoint: response shape/example, inputs and price — inspect before paying.
endpointstringrequired
solmachina_how_to_payExplain the x402 402->sign->retry flow so an agent can pay a paid endpoint with its own wallet. FREE.
endpointstring
solmachina_verify_receiptHow to verify a paid answer's Ed25519 SIR receipt OFFLINE (proof of what you paid for). FREE.
receiptstring
solmachina_statusTrust/health snapshot: version, uptime, WAL entry count + SHA-256 chain head. FREE.
solmachina_smriSolMachina 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>.
mintstringrequired
solmachina_simulatePre-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>.
txstringrequired
solmachina_decisionSolMachina 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).

solmachina_token_holdersSolana 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>.
mintstringrequired
solmachina_slippage_mapSolana 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). Execution intelligence beyond a single /v1/dex-quote. A quote, NOT an execution guarantee. NOT financial advice. Requires ?inputMint=&outputMint=&amount= (input base units).

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

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